Terna, the company that manages the Italian electricity grid, has tendered the contract regarding “civil engineering work for the 132 kV substation in Collesalvetti (Livorno, Italy)”, i.e. a project of exceptional importance, to Salvati S.p.A., that for the foundation work has turned to the machinery and equipment of the company Locafond S.r.l. and in particular the Enteco E9080. The latter has been called on to install numerous foundation piles using soil displacement technology (lateral soil compaction). There seems little point in stressing that the site called for exceptional output capacity and speed of execution, re uirements fulfilled to perfection by the nteco drilling rig that actually set records. The piles of 32 m in length were installed in 9 minutes: 4 minutes of downward boring to make the hole, 5 minutes to cast the concrete.

switching station in the village of Guasticce. The new infrastructure will link the Livorno Marzocco-Marginone, Guasticce-Cascina, Guasticce-Pisa Porta a Mare and Guasticce-Acciaiolo Livorno overhead power lines, making the local grid safer and more efficient, reducing grid losses and the risk of power cuts. It will also help to deal with the increased demand for energy following strong residential and industrial development in the area that is located close to the Amerigo Vespucci Freight Village in Livorno. The new 132 kV double busbar facility with air-insulated switchgear will be completed in around three and a half years, extending over an area of more than 18,000 m2. The substation will be placed on an embankment in order to ensure optimum safety based on the hydraulic properties of the area in question.

The new infrastructure

The Tuscan construction site

Terna is the company that runs the national high and extra-high voltage power grid and is responsible for distribution. The company, a coordinator and enabler of energy transition and an increasingly structured and innovative electrical system, has always been committed to and focused on the sustainable development of infrastructures so as to protect the environment and local communities. To this end, Terna has opened the construction site for the new Collesalvetti 132 kV

In the circumstances, Terna has awarded the contract to Salvati S.p.A., a leading player in the Italian construction sector. Founded in Terni as a sole proprietorship by the surveyor Francesco Salvati, in the nineteen sixties the company began to grow and branch out into other areas with the first si able contracts from and Today it is a joint-stock company operating in the sectors of road construction, manufacturing facilities, renovation, civil engineering and special structures. In short, the ideal

company to take responsibility for such an important contract as the Livorno one. However, the Collesalvetti construction site is also a nice tale of synergy between Italian businesses. For the special-foundation work, Salvati used the plant and machinery of the Treviso company Locafond and in particular an Enteco E9080 drilling rig (therefore designed and constructed by Enteco in Venice) equipped with the soil displacement kit and an Enteco E 8018 crane for installing the cages and site service activities. We are talking about a total of 720 piles installed using soil displacement technology with diameter of 420 mm and 620 mm and depth varying from 31 to 33 m.

Complex stratigraphy

s happens on all construction sites, the first thing to do is check the condition of the soil. Down to a depth of about 22.5 m, the Collesalvetti site had a fairly uniform stratigraphy with the sequence of alluvial, silt and paludal deposits, followed by lagoonal soft clay deposits and finally sands n digging deeper, an important lateral variation of gravel and sand was noted. Careful geological studies revealed greater density only when approaching a depth of 30 m. As can easily be imagined, this is not a simple stratigraphy, given that as far down as the soft clay, the soil has no bearing capacity. This led to the choice of soil displacement as the drilling technology. To support this technology, the natural choice was an Enteco E9080 drilling rig equipped for soil displacement application in which the company from Venice is a veritable specialist.

Soil displacement technology

In order to increase the bearing capacity, the E9080 SP300 installed thick-mesh piles (2.5 × 2.3 m) of depth ranging from 31 to 33 m with lateral compaction provided by the Flagship of the E9000 series, the Enteco E9080 features the exclusive E9000 Mast Support System

Solutions also designed to reduce costs, vibration, noise and consumption. special rotary displacement tool also designed by Enteco. he benefits of soil displacement are now well known: this technology produces no drilling waste, therefore reducing transport costs, keeps the site area clean and, above all, is safe for the workers. And should that not be enough, it enables an increase in the natural density of the soil, so that the pile has greater bearing capacity. In this respect, Enteco studies have shown an increase of between 25% and 40% compared to a CFA pile of the same diameter. Thanks to sizeable research and development investments, use of state-of-the-art components and extensive experience in the field, nteco machines have received important international acclaim for their soil displacement capabilities in construction sites all over

he nteco is the flagship drilling rig of the series that includes models from 75 to 200 tons. Its main feature is the exclusive E9000 Mast Support System providing the mast with excellent rigidity and high torque along its entire length. Improved rigidity is provided by a large triangle conformation formed by, at the bottom, the connection between frame and mast and two long backstays (comprising extremely solid steel hollow sections) that connect the frame (at the centre of the machine base) to a point very high up the mast. The system also allows the mast to be lowered and touch the ground. The mast’s articulated joints are also of great

The entire layout of the machine is designed to allow easy maintenance of the components through a special opening in the bodywork and a corridor in the middle of the frame. At the same time, the engine is readily accessible by opening the hatches located on all sides. Another feature of the E9080 is the EIAS (Enteco Interactive Automation System). The EIAS means that all machine operations, from work to transportation, are automated and continuously monitored. The EIAS also allows remote troubleshooting and consequently a fast response from the service department.

Furthermore, the availability of a larger area will also enable us to better manage the construction of larger machines, as our market is requesting”. The company has also invested in another CNC centre (the company has now a total of five a ak centres for high precision components, i.e. the components needed for rotary heads, drifters, motors, clamps, etc. Through this project, Marini QG will increase its indoor area by around 50%.

production. It is also worth pointing out that there is a test field next to the manufacturing area where drilling can be performed, both in the ground (whose stratigraphy is actually quite demanding) and also in rock due to the presence of a block of granite that is regularly replaced and enables verification of machine drilling speed and operating efficiency, particularly when fitted with external percussion systems. “90-92% of our machines”, Zaninetti advises, “are built in-house. As regards mechanical parts, only surface treatments of materials are outsourced, whilst we source our components from Italian manufacturers, or European ones, with Germany in the front line as far as hydraulic parts are concerned. The internal combustion engines are eut , ohn eere, anmar and Kohler. In any event, the choice

As previously mentioned, Marini QG will be unveiling the brand new MR-P 400 at bauma. “We entered the piling market”, Zaninetti resumes, “with the small MR-P 350, following a request from our Californian dealer who was looking for a machine in small sites. After this first rig, we built several others in a couple of years and this led us to look at this market more closely.

mongst the recent innovations also applicable to track-mounted machines, worthy of note is the M-Tronic, the new operator interface with 7” display that allows the entire machine to be controlled electronically, including through the dedicated app, available for computers and smartphones The system unveiled at bauma, actually installed on the MR-P 400, can support the operator and manages to provide interesting feedback from the machine. Indeed, whilst in use, the operator can monitor drilling depth, mast angle, operating pressures and interact with the machine in order to change principal settings in real time.

versatile machines are required”. This piling rig has a fairly long reach for the installation of standard bored or cased piles. “At bauma”, Zaninetti continues, “we will be exhibiting a machine with a seven-section kelly bar for a depth of 22 m, but you can have also a nine-section kelly bar to reach 27 m depth: the machine is supplied ready to accept both solutions. Whilst our competitors for machines of approximately 15 tons tend to offer a single-engine rotary, we wanted to offer a little bit more durability and rotary torque, and we opted for a twin-engine head offering greater speed (rpm) and allowing better torque control, especially in the CFA version. Furthermore, the twin engine gives the rotary head better protection by distributing the torque over the main gear in a more uniform manner he kit can be fitted very easily and thus installed on-site in about one working day without any assistance. Additionally, in CFA mode you have the possibility of fitting a third auxiliary winch (pull down that can also be retrofitted and combines with the main winch and the service winch. It is also worth pointing out that the machine is mounted

on a ero tail swing base, making it easier to handle on sites with confined spaces or when working at the roadside. Also ideal for the Italian market, it has a reduced height and can also be used in low headroom situations. “The machine exhibited at bauma” Zaninetti resumes, “has already been sold to our french distributor, whilst the second one, with both kelly bar and and CFA kits, has already been reserved

At bauma, Marini is also exhibiting an MR-C 85 which is a drill rig designed for anchoring works, an MR-C 20P and a MR-2PN, along with drifters and rotary heads. “This is our debut at bauma and we have a booth of around 150 m2”, Zaninetti concludes. “It is a very busy period, so we expect a really interesting show: the first truly 1 international event. There are one or two doubts about the American market, because Conexpo is going to be held ust five months later and this could put off a few visitors”.

this year. Seventy years of business, seventy years of history, seventy years of drilling. We are talking about MAIT’s anniversary, stretching over a period almost equal to the life of a generation. And in a way it is.

THE BEGINNINGS MAIT was founded in 1952 by Emilio Tonti with the help of his wife, Enrica

Camilletti: together, they worked very hard to establish and grow what was, historically, the drilling sector’s first Italian company he fifties were characterised by great spirit of enterprise: the memories of the war and its pain and sacrifices were still vivid in everyone, prompting a desire to start again, rebuild, put into practice and realise new ideas and dreams that would improve or even change lifestyles. At that time, there was a widespread spirit of enterprise that would eventually lead our country

into a period of sizeable growth, both of consumption and the economy. Many companies were established and the regional or provincial geographic areas began specialising in certain types of product, laying the foundations for what future generations would come to know as ‘Made in Italy’, characterised by family-run businesses forming the basis of a social and economic fabric comprising ideals, traditions and innovation. Yes, there was already a lot of innovation: every businessman was fully focused on the development and improvement of his product and not on bureaucratic or social issues. As a result, MAIT immediately offered reliable, hard-wearing products that have been the basis for solid corporate growth.

until becoming an international player, it has diversified its business into other sectors, thanks to the development of composite materials and interests in the on-shore sector. How much of company turnover concerns activities relating to the development and marketing of composite materials? M.G.Tonti: omposite is certainly going to be the steel of the future and this can already be seen, for e ample, in the automotive sector The e perience and knowhow that T has ac uired in the wind power sector has enabled us to perceive and nd new and different technical hori ons for composites that can be applied to drilling rig construction urrently, all T hoods are manufactured in composite

has been dealing with extremely competitive markets, such as the American and Japanese ones, for years. As of today, the company’s goal is to further expand its horizons, focusing on technical evolution and, for the first time, the introduction of machines for rental use, but also and most importantly, the creation of new types of construction machines (stay tuned!).

A SPECTACULAR YEAR It is good to say that has been following an upward line for 10 years now”, says Giacomo

Giacomo Cartechini, CEO of HPM

artechini he year 2022 in particular sees us growing not only in terms of machine sales but also in terms of strength. A push forward that required us to invest in resources, expanding the staff of the technical and design department. In addition, through the large increase in material in stock, we have been able to shorten delivery times significantly at a time when the opposite is much more likely to happen hese choices have opened the door to new possibilities for growth in markets still unexplored for us o conclude a splendid

Blaze Equipment

“Blaze Equipment is the exclusive North America dealer for HPM. Blaze Equipment was founded to directly address a lack of support for foundation drill rig operators in the eld and the poor uality of after-sales service often found in the industry The founder was a previous drilling Contractor and much of our staff were Managers of Drilling Businesses or Owners themselves. Our extensive background in drilling means we understand how to create a reliable partnership that helps you, the Drilling Contractor, succeed. Working with HPM has been one of the best relationships you could have between a Dealer and Manufacturer. The corner stone which HPM laid may have been small to start, but it was a strong corner stone that turned into the large and growing foundation that is the HPM you see today. That foundation has been built on ease of communication between HPM, end users, and Blaze Equipment. The advantages that HPM has over other rig manufacturers are 10 Rotary Speeds, Self-Erecting counterweight System, upper House lock, Parker IQUAN System, Larger Tooling Capacities in front and under the Mast, and more importantly, the best torque/weight ratio in their class. Blaze Equipment services the U.S. for all after sales and support la e has a rental eet of units and continues to invest in the growth of the rental market”. Matthew Loghry, General Manager Blaze Equipment

essentially oriented toward the U.S. and then apan he participation in bauma and the recent 1 year celebration event mean an interest to the Italian and European markets. “We have always wanted to be part of the Italian market and make our contribution”, explains Cartechini, after all, ours is a proudly ade in Italy production o demonstrate this, we are investing in the rental field by offering the possibility to rent our machines for short or long periods, directly from us, without going through local dealers o date we already have 5 models of machines available that can be configured as needed he goal is to have at least one machine per model always available in the rental fleet

THE TECHNICAL INNOVATIONS In addition to the new commercial purposes explained, bets on technical and technological innovation he strengthening of our technical staff and design staff is giving us the opportunity to work on multiple projects simultaneously”, says Cartechini. “Staying true to the drilling industry, in 2 2 will introduce two types of machines that are completely different from what you are used to seeing. In addition, through the study of specific pps we are revolutioni ing after sales services and interfacing with users by giving periodicity to exchanges of information in order to make routine and extraordinary maintenance as quick as possible”.

Reliability, versatility, technology Gennaretti centrifugal systems are used in the “Costa Francara” microtunnel construction site, in the batch 2 of the gas pipeline San Salvo-Biccari from Apulia to Abruzzo

I

n Molise countryside, surrounded by a landscape with sea view and by the elevations of Campobasso province, the hills are not just a place of agricultural development, but they become the main character of an important excavation work. The centralsouthern position of Molise region makes it one of the main places of gas pipeline San Salvo – Biccari crossing, which travels through southern Italy from Apulia to Abruzzo. Right there, immersed into the green landscape of Larino in Campobasso province, Italy, there is a MTBM of I.CO.P. S.p.A. (a company specialised in special ground work construction), which is working for a microtunnelling excavation, contributing to the construction of batch 2 of the gas pipeline, which will guarantee a direct connection between southern and northern Italy for 88 km.

THE CHALLENGE The “Costa Francara” microtunnel construction site is located in an uncommon place, just behind a hill. Despite the panoramic setting, this hill presence makes the excavation works difficult, since the incline

Who is Gennaretti

G

ennaretti is an Italian company from Jesi in Ancona, Italy province and it works in industrial equipment sector from 1983, by producing centrifugal systems and plants for water and slurry treatment. It has a strong presence both on Italian and international markets, by having more than 400 installations. The company studies, plans and builds its centrifugal systems and guarantees the high quality of “Made in Italy”, which stands Gennaretti out from the competitors. Innovation and high-technology are the main principles on which the production is based and through which Gennaretti can adapt to the development of sectors, such as tunnelling, drilling, mining and special foundations.

Let the customer speak ➜

“The experience with Gennaretti is absolutely positive” says Ing. Marco Dusso, construction manager of Costa Francara Microtunnel, “from different points of view: for the system, really efficient and safe, for the people that work in this company, for the continuous assistance both in electronic and mechanical components, and for the process”.

causes an unstable ground and its geology seems to present some management problems. The preparatory geological studies highlight the presence of clay, a material whose density and viscosity are not adequate and which would get slower the works. Therefore, separating drilling slurries becomes a necessary action in order to keep

on with works without obstacles. Thus, the company decided to seek help from Gennaretti and his separation technology. It is not the first time Gennaretti takes part to these major works, since the relationship with I.CO.P. is longstanding. The company has relied on Gennaretti separation technology for years, whenever it has


# G r e a t . M a c h i n e s . W o r k i n g / @G E N N A R E T T I

to face problems related to ground slurries and waters.

THE SOLUTION Generally, there are two problems within building sites: the first one is the space management, since it is limited and it should be organised and optimised; the second one is the time management, as the works should go on constantly and without delays, which in this case are caused by the ground geology. I.CO.P. has found an innovative and rapid response to those issues thanks to the Gennaretti centrifugal systems. The S.P.A.C.I. 22 plant is the convenient, flexible and adaptable-to-space solution provided by the Italian company. It is supplied with all the mechanical and electronic components and it does not require masonry or civil works. The installation in container allows the product to be easily transportable and, mainly, transferable from a building site to another taking up a minimum amount of space. Inside the container, Gennaretti has installed a GHT 403VF-75kW decanter centrifuge, that can guarantee process speed, since it can treat several flow rates (from 1 to 25 m3/h) and can reach high-speed rotations (from 500 up to 2,000 rpm).

THE RESULTS Reliability, versatility, high – technology: three key factors from

The service

The centrifugal system is supplied turnkey and it can be powered up as soon as it arrives in building site, without external operators. Gennaretti specialised technicians support the process of commissioning and start-up of the system and are ready to provide assistance in case of difficulties and to carry on ordinary and extraordinary maintenance.

which excellent results come from in building site. On one hand, the opportunity to generate water useful for construction site activities means immediate availability, which helps the excavation continuation rapidly complying with construction times. Moreover, it is a good way to save clean water. On the other hand, solid-liquid separation produces outgoing dry solid, which is highly stackable. The material volume to dispose of will be clearly to a lesser degree and it will be possible to transport it and dispose it of as excavation rocks and ground. In addition, the work will not be obstructed by a soft clayish material and density and viscosity will be adequate for an optimal advance of the MTBM.

Outline Stroke

THE OPPORTUNTY OF DECANTER CENTRIFUGE Separating drilling slurries definitely represents an economic advantage from disposal costs’ point of view, which will be lower, but it undoubtedly represents an opportunity. Nowadays, the trend towards a circular economy, to the issues related to water scarcity and everything concerning water consumption lead us to adapt us and our products to this necessities, as well as to limit any waste. The

opportunity derives exactly from there: the water generated from the separation process can be recovered and reintroduced in building site. Generating clean water means producing a liquid, which is adequate to reuse for its chemical features. The high-quality construction of the Gennaretti centrifugal systems, supported by a suitable cycle of organic-based additive dosage, allows to separate clay’s finest particles (from 0 to 63 µ). The microtunnelling company will be able to reuse water for excavation works, a necessary requirement for the construction site beginning.

AUTO... matically. In Germany Stuttgart. The company Geopunkt is installing 63 cased piles of diameter 600 mm and 900 mm to depths of between 10 m and 21 m. In order to tackle the difficult stratigraphy it is employing several SIP&T Automatic Casing Drive Adaptors (AUTO CDAs) and tools

T

he quality of SIP&T products demonstrates its worth abroad as well. e are in the indelfingen stadium where the automatic casing drive adaptors patented and manufactured by SIP&T are showing their worth on the

construction site along with double wall screw type casings, buckets, augers, core barrels, tremie pipes and the accessories needed to meet all site requirements. The pile installation speed is ama ing and beyond all expectations. The AUTO CDA eliminates the need for manual

connection of the casings to the drive adaptor and so there is no downtime.

A word from the parties “I know SIP&T and have been using its products for more than twenty years” explains Ciro Ponticelli, Geopunkt foreman and operator. “Right from my earliest experiences, I have always appreciated the willingness of its engineering/sales team to understand my requirements and transform them into the right tools for the project, stratigraphy and the drilling rig to be used. People often make the mistake of considering the drilling rig as the one element required and sufficient to carry out drilling This is a serious blunder, because without an operator with the necessary experience and without bespoke tools, you cannot meet deadlines and budgets that are now the main targets in a project. I introduced SIP&T to Geopunkt management and I must say that as things stand we are e tremely satis ed with the partnership because the on-site results obtained in terms of rapid execution demonstrate perfect synergy between the manufacturer of the drilling tools and their user. The AUTO CDA really impressed me, it is an innovative, sturdy and userfriendly tool. Before starting to use it, we received training from SIP&T engineer, Francesco Cantisani, who pointed out the operations to avoid. After more than a year’s use, it has been entirely problem-free and we have yet to replace a component. This is also thanks to the scrupulous manner in which we operate that includes frequent lubrication of mechanical parts”.

“we have always been proud to promote the idea that a product’s high quality offers guarantees in terms of reliability, life expectancy and sustainability. Therefore, all new products we are introducing at bauma have been designed to meet these prerequisites, essential in tackling planned obsolescence, i.e. deliberately planning for a product to have a limited lifespan, in order to restore a relationship of trust with the customer and harmony with the environment we live in”. The logical consequence of this approach is an enlarged product range. The Autec development teams have undertaken to improve existing models and develop new ones, designing solutions offering greater

capacity, higher performance and more customisation options that satisfy new applications. Furthermore, quite clearly, we have never halted the process of certification and compliance with international standards. Several important innovations will be introduced at the trade show and in this article we can give you an advance preview of the most interesting ones.

AUTEC AT BAUMA

The new DCRF13 compact base station is designed mainly for forestry and mobile applications

Therefore, the October show is not to be missed so that you can finally see the latest technical innovations first hand and chat with Autec sales managers and engineers (open-air area FM, stand 807/9) in order to exchange opinions and ideas.


But what are the main innovations that Autec will be unveiling? Amongst the waist-worn wireless systems, the new M-PRO and R-PRO will attract the greatest attention. These two ergonomic portable stations are designed for the Dynamic/Dynamic+P series and have a medium/high number of actuators available, high control reliability and excellent battery life. The AIR series Sidekick family has two new additions, the waistworn portable stations SK8B (with double row of actuators and possibility of fitting 1 display and SKL (version that enables fitting of up to two linear oysticks

Staying with the AIR series cableless control system, it is extremely interesting to note that the stop function has been certified by the leading international body TÜV Rheinland. This means that the GSS/EMS/ATS safety functions comply with PL e according to ISO 1 1 and I according to I 2 1, meaning that utec control systems are indeed extremely dependable in a market demanding ever increasing reliability.

renewed stand, three machines that well represent Tescar design and a great desire to meet customers and enthusiasts of the sector. These are the ingredients that will characterize the presence of the Marche manufacturer at the next bauma.

THE SMALL WONDER The CF2.5 COMPACT, called “The Small Wonder” by the North American customers, is undoubtedly one of the symbols of the brand. A model invented in the late 1980s by the current owner’s father, it was a technological gem that turned the concept of the mini-drill upside down. At that time Tescar had already launched several models of drills mounted on mini-excavators such as the CF2.5 and the CF3 S, with minimum working heights around 3.5m; but, you know, we are in Italy, and many jobsites require working inside existing buildings, awkward spaces with very low working headroom. And it was on the request of one of a longstanding customers from Osimo (“the city of piling rigs”) who needed to work at 2.8 m that Tescar decided to design a machine from scratch, with a special chassis equipped with an extendable undercarriage and mast support with counterslide device to allow working at a minimum height of even 2.5 m. “An achievement”, says Antonello Verdolini, Tescar Sales Director, “that has never been matched by anyone else so far, as an evidence of the excellent work done by our designers”.

The CF2.5 Compact is called “The Small Wonder” by the North American customers


Now, the new CF2.5 Compact has been equipped with dual hydraulics for the possibility of mounting 2 different rotaries, with 25 and 35 kNm of torque, and has been fitted with a brand new and innovative radio remote control that, thanks to the new electronic system developed by Tescar engineers, allows the operator to see on the display the whole range of information that would normally be shown on board the cab of an excavator. The machine is then equipped with a removable power-pack to be able to work inside delicate and/or inhabited structures, avoiding noise pollution and especially environmental pollution due to exhaust from the heat engine. Mechanically then, the new CF2.5 Compact can also be equipped with a special kit for reverse circulation drilling, an option that enabled an important Japanese customer to win the contract for the construction of a section of the new electromagnetic suspension railway linking Tokyo and Osaka.

power-to-weight ratio in its class”. In particular, the version at Bauma is the “CFA Extended” i.e. the configuration for 1 m depth (12 m propeller + 4m extension rod), equipped with oil-bath rotary and double slewing bearing for k m of torque, heavy duty expandable undercarriage 2,500-3,500mm, auger cleaner star-type with ropes, 24 t extraction force with main winch on III layer pull, additional 4 t pull-down winch on II layer pull and on-board data logger for recording drilling parameters. All with a total weight of 23.5 t. This model, mounted on a CASE excavator base mod. CX130, is equipped with all the latest safety devices, both active (such as electromechanical limit switches, electronic detection sensors, perimeter cameras, gps and remote control of engine parameters) and passive, such as the ops ops level II certified cabin.

The most important international trade fair for the drilling & foundations sector will be held in September 2023

F

ollowing a 2021 edition which has registered record numbers (250 exhibiting companies with more than 350 brands, almost 9,500 visitors including 12% from abroad representing 54 European and non-European countries) confirming the validity of the Geofluid exhibition format, the show scheduled for September 2022 has been postponed until 2023 due to the pressure on the supply chain that is affecting all sectors, along with an outlook of instability that does not guarantee sufficient international mobility to meet exhibitor expectations. We must also consider increasing energy costs that are severely affecting manufacturing. Therefore, Geofluid will next be taking place from 13th to 16th September 2023, a time that will become extremely important when planning future work in the drilling, foundations and underground engineering sector, not only on the strength of a desired market recovery, including as regards international stability, but also new challenges associated with the post-pandemic upswing. In the EU 2021-2027 budget, a

large part of the resources of the European Regional Development Fund (ERDF), running into billions of euro, will be allocated to renewables, decarbonisation and energy efficiency improvement and the use of funds from the ational ecovery and Resilience Plan will be in keeping with the provisions of the European Green Deal. The actions to be taken regard renewable energy investment and research programmes, schemes to combat hydrogeological instability, efficient use of water and improvement of inland water uality The plan allocates substantial resources to land safety, meaning hydrogeological risk mitigation (with prevention and restoration projects), the elimination of water and soil pollution and the availability of water resources as primary infrastructures and purification

should pursue as part of their company’s social responsibility. Obviously, innovation cannot be an objective in itself, but should rather provide an effective response to latent or evident market needs. Discussions and listening to the technicians carrying out tests in the field were essential in defining the TGAS-12’s characteristics.

Drilling: What do technicians r i i the field re ire from a data logger? Edoardo Pagani: Simplifying is the key word. Simplifying, which means being practical and easy to use, quick in the acquisition of data with high performance levels. The more advanced and sophisticated the device, the more one expects

T

he TGAS-12 is lighter and more compact, much quicker in acquiring data and more intuitive to use compared to the previous model, the TGAS-08. For many years, this had been the top-ofthe-range model for the Company in Piacenza, as well as the reference standard for carrying out electronic penetrometic tests. We asked the owner of the Company, Edoardo Pagani, to tell us how the TGAS-12 was developed, and outline some of the main new features that we can expect.

Drilling: How did the new TGAS-12 come to be? Edoardo Pagani: In the industrial sector, innovation is often driven by commercial considerations, but in the case of the TGAS-12, our primary motivation was wanting to create something completely different from what already existed.

The idea of re-inventing the data acquisition system for electronic tests was conceived in 2019, but took almost three years to develop. A long time, which was also overshadowed by the pandemic, while we aimed for excellence, without ignoring any of the functional or aesthetic aspects.

Drilling: What do we mean by innovation? Edoardo Pagani: I believe that innovation is a value in itself, an objective that all entrepreneurs


previous versions. Thanks to the new programme, running tests in the field is fully automated: the system detects the information referring to the connected piezocone, the installed sensors and the seismic module connection, with the operator not needing to enter any data. The calibration test is also done by simply clicking on the screen. The programme guides the operator every step of the way, reducing the time needed to carry out the test as well as the risk of human error. To ensure data is reliable, considerable work was done on electromagnetic compatibility and immunity in a civil environment. in terms of precision and reliability from the tool. On this basis, most steps and processes in the TGAS-12 were fine tuned to make it simpler to use, and increase its performance in the field, whilst also reducing errors to a minimum”.

Drilling: In what way does the ease se i pa t the data l er s per r a e Edoardo Pagani: The simplicity in using the device allows it to express its potential, whilst taking into account the fact that time is a fundamental variable when running a geotechnical test. To save on time, it can happen that not all the functions available are used, if these are cumbersome or complex, or

one can use expedients that could then increase the risk of committing errors.

Drilling: a y hi hli ht some of the more relevant innovations made to this model? Edoardo Pagani: We have introduced significant improvements to certain hardware components and have updated the operating system, making it more intuitive compared to

Size Matters

The TGAS-12 is more compact and lighter than the previous model: 42% less weight, 52% less volume, but the same 12” screen. The new data-logger can be transported in a small case, and this also helps to reduce the time needed to startup and carry out the tests.

Drilling: It also seems that the TGAS-12 differs from previ s dels r a aestheti perspe tive hat has changed? Edoardo Pagani: The design is also an essential feature for a data logger, because it reflects the care taken in its planning and increases its value. In addition, in the case of the new capacitive touch-screen monitor, the modern design combines with a substantial improvement in functionality, because the flush screen with its frame prevents water from remaining inside the device, when it is being used in the rain. The screen is also perfectly legible in direct sunlight. Regarding the hardware, the TGAS-12 uses new generation push-pull connectors, which ensure more efficient performance and require less maintenance. The data-logger is resistant to water, dust and extreme temperatures (-20 ÷ +70 °C)”.

TracMec, as our title shows, assists OEMs with the most difficult tasks in order to build, day after day, increasingly competitive, higher performance machines

I

n the undercarriage world, TracMec certainly has no need for introductions. Indeed, as is often the case, the figures speak for themselves. From 2005 up until today, the company from Mordano has manufactured more than 2,500 undercarriages with an average weight of around 24 tons. But besides the numbers, there are the ideas, the people, i.e. those who really run a business.

PRODUCTS AND FIELD OF APPLICATION rac ec manufactures fixed and extendable undercarriages, supporting customers with complete tracked solutions, so that

the end user can gain a competitive advantage. We are talking about bespoke serial designs that enable the machine to exhibit superior performance, confirmed by drivers stating that they can identify the machine has a TracMec undercarriage, even with closed eyes. And as if this were not enough, the Italian manufacturer recently acquired new projects and improved its organization leading to further deployment of its distinctive competences such as milling and welding. “In a nutshell , explains rac ec ales Manager, Lorenzo Landi, “we

Eng. Lorenzo Landi, TracMec Sales Manager

design and manufacture crawler undercarriages for drilling rigs, cranes, demolition excavators and other types of tracked industrial machinery. The core business is represented by extendable undercarriages that offer adjustable track width to have maximum stability when working but, on the other hand, a reduced width during transportation or when working in narrow and confined spaces In addition, there are crawler tracks and fixed undercarriages for more niche applications such as forestry machinery or for aggregate processing”.


A DEEP TRANSFORMATION “In recent years”, continues the manager from Mordano, “TracMec has evolved in every respect: from the implementation of technical solutions to the type of undercarriage produced, representing one of the new

corporate challenges, and finally the implementation of a new organisational structure in order to be better equipped to face the market and the latest challenges. We are designing and building ever more challenging products with increasingly distinctive

specifications and optionals requiring robust, but also userfriendly and effective, technical solutions. And in order to take up these challenges, there is just one secret: to believe in continual improvement through the right blend of in house experience and know-how and encouraging new staff to be innovative. A mix to enable these challenging objectives to be achieved as they evolve over time. This leads to the importance for a deep internal change to the organisational structure that is now stronger and more resilient, prepared for external changes and looking towards an increasingly changeable and dynamic future”.

A word from Alberto Dalle Coste “T

racMec’s aim is to support its customers’, i.e. the machine manufacturers (OEMs) operating in the various construction machinery sectors, in particular drilling and hoisting, in order to provide complete crawler undercarriage solutions so that the end user may gain a real competitive advantage. A mission that we pursue with the

aid of skilled staff who love their work. In order to reach these objectives, the optimisation of design costs is an important challenge to be achieved by streamlining projects and using high quality components. In this respect, it should be stressed that our main suppliers are located within a radius of just a few kilometres from our facility

and are characterised by their exceptional skills. Whilst on the one hand there are threatening clouds such as the pandemic, war and supply chain problems, the future also holds great opportunities in store for us such as electri cation, digitalisation and the need for machines to use renewable energy as best they can”.

The range

TracMec undercarriages can basically be split into three families: extendable, ed and electric undercarriages n turn, the e tendable ones, that obviously offer more versatile, e ible and stable machines, can be split into parallel, H-frame, telescopic and pantograph undercarriages. The latter are very popular on cranes and hoisting systems in general Trac ec ed undercarriages can be designed and produced with central chassis (with or without crossed roller bearing), cross members or crawler tracks alone. Meanwhile, the electrical products can complete the technical possibilities for special machines as they can e clude, or at least limit, the use of hydraulic uid

THE FORTHCOMING CHALLENGES Whilst the medium-term objectives can be summarised in the ‘Road to 25’ project, a challenging objective of achieving sales of 25 million euro in 2025, 25% of which by the parent company Bauer, on the other hand, the short-term challenges are those that torment many manufacturers. Landi resumes: “components not delivered, delays notified at the last minute and continuallyrising costs have been a feature of the last few months, if not years. Achieving cost stability and then also managing, where possible, to stabilise prices has been this year’s business leitmotif. And at all times with an eye on essential economic indicators.

Many of these construction sites are concentrated in a hundred kilometers stretch along the coast of Abruzzo, from Giulianova to Vasto. In addition to the refurbishment and reinforcement of these structures, the projects under way are aimed at improving the anti-seismic performance of the viaducts, located in a region of Italy that is known for a high

level of earthquakes. The general contractor Divisione Cantieri Stradali S.r.l. was awarded the contract by Autostrade per l’Italia S.p.A. (the joint-stock company that manages this motorway section under concession). Thanks to their cooperation, we were granted a visit to one of these construction sites, located in the municipality of Vasto.

THE CONSTRUCTION SITE “The project involves the seismic reinforcement of the entire viaduct, which is approximately 400m long, as well as the simultaneous reinforcement of the foundations of all piers and abutments.

The use of sensors and electronic devices that detect the position and inclination of the machine has allowed to speed up and facilitate all positioning phases

Indeed, the project envisages expanding the existing structures on which the piers rest, in order to increase the number of piles that currently support the base of the foundations”, explain Mr. Marco Pezone (Site Manager) and Mr. ario Iorio of the urchasing ffice of Divisione Cantieri Stradali S.r.l. A total of six piles of 1,000mm diameter will be constructed beneath each of the piers for both carriageways. The lowest piers will require piles of 20m depth, whilst the piles beneath the highest piers, will be 25m deep. “The additional piles have a larger diameter compared to those of


the existing piles,” the managers of Divisioni Cantieri Stradali S.r.l. confirm moreover, as they are positioned further away from the centre of gravity of the pier, they are better able to absorb the normal stress caused by the movements of the piers compared to the existing piles. The same can be said for the shear stress.” Given the characteristics of the region, the piles will be tested, taking into account the subsequent stresses from the full spectrum of seismic actions. The existing structures will then be integrated within the new design. Characteristically, the soil within this area is typically made up of consolidated clays with sand and silt layers and intermittent pockets of aggregates of about 10cm diameter. The Site Supervisor, Mr. Vincenzo De Cristofaro explains, “the main challenge we are facing on this site is the low headroom. The drilling and grouting needs to be performed underneath the viaduct, with a clearance ranging from a minimum of 7m to a maximum of 19m below the deck beam “.

THE SITE’S STAR This is where the new Comacchio CH 150 comes into play. The rig is operated by a Vasto-based foundation contractor, dilflorio

S.r.l., who are responsible for the completion of the installation of the foundations. This latest addition to the CH range of Comacchio piling rigs (unveiled during the last Geofluid , uses an 1 ton class excavator as a base carrier. This excavator is equipped with a modular mast system and a multifunctional rotary head. Thanks to its design, the Comacchio CH 150 can be utilized for the construction of both bored piles (with or without casings) and CFA piles, using simple conversion kits. “The compact size and low weight allow for trouble-free transport of the machine with the rotary head and Kelly bar in

situ. The design and construction of the CH 150 allows for access construction sites with difficult access conditions. Our company mainly operates in Central Italy, where the majority of the terrain consists of mountainous areas, and therefore, the road connections are not conducive to the movement of large and heavy vehicles. Many of the projects we complete often involve the construction and maintenance of medium-sized infrastructures which require us to operate in small and difficult to-access spaces, under bridges, adjacent to roads or alongside railway lines. The Comacchio CH 150, with its compact size, is the ideal solution for these types of pro ects ithin the confines of this construction site, we simply remove the cathead to allow us to operate in low headroom conditions”, explains Vittorio Florio, who, along with his father Giuseppe Nicola, heads up family owned dilflorio r l Positioned between the piers of the viaduct, you cannot but notice the extremely small footprint of the machine. This is possible thanks to the base excavator configuration which accommodates the ballast within the size of the tracks. What is striking is the agility with which the machine manages to complete the entire work cycle. Such maneuverability is simply unthinkable for larger, heavier, and cumbersome “conventional” piling machines. “The kelly set-up allows for the installation of bored piles with a diameter ranging we are

The sensors and electronic devices used to detect the position and inclination of the machine allow for the increase of speed and facilitate all positioning phases. Moreover, sensor technology allows for the machine to automatically adjust the set-up to synchronize with the actual operating conditions, thus preventing potential hazards. All machine functions are managed through the Comacchio Control System (CCS) software, which provides the operator with comprehensive data of the machine operating parameters via a userfriendly touch screen display. The hydraulic system of the base excavator has been optimized for this type of application. The CCS system electronically controls the diesel engine, thus allowing the hydraulic system to acquire the maximum available power from the engine and therefore maximize productivity. In addition, the cooling system of the base excavator hydraulics has been enhanced to cope with demanding environmental conditions along with the intensive use that is typical of a foundation construction site. In this instance, construction will continue once the seismic reinforcements on the viaduct piers is completed. Mr. Pezone concludes, “further construction work will be carried out on the abutments of the viaduct, both on the north side which will be consolidated using a jet grouting technique to discharge a proportion of the seismic stresses, and on the south side with the installation of five active tie rods which will assist with a reduction to the shear stresses on existing foundations ”.

from 750mm to 1,000mm. In this case, we are working to the maximum diameter achievable, to a depth of 20-25m, which is quite an achievement for a machine within this weight category. The CH 150 is proving to be more than capable of meeting the needs of this task, thanks additionally to the 44 kNm torque rotary head that has the option of being operated in “constant power” mode. Essentially, the regulation between speed and torque occurs automatically, thus optimizing performance “, Vittorio

continues on average, we complete four piles per day with production only slowing when we encounter particularly stony layers.”

Performance and productivity are not the only advantages the CH 150 offers. The same systems that are normally used to optimize efficiency and safety on their larger piling machines are consistently applied by Comacchio to the smallest rigs within their CH range.

while increasing the safety and simplicity. Free fall winch: When crowd force is applied on the Rotary/Kelly Bar, the main winch will automatically release the rope without the pressing of any buttons or pedals. Automatic winch stop function (swivel up function): the main winch stops automatically when the operator reaches the bottom of the hole with the tool, but with the cable that remains tensioned while keeping the swivel joint in a vertical position. The swivel on top of the kelly bar will remain upright and hold the rope in a vertical position. This results in easier operation, less wear and tear on the main winch rope and greater


lifespan of the main winch. Every single command on the IMT is performed using direct feel hydraulics. IMT will present its product range in different configurations at bauma 2 22

A70 The latest is the A70, a powerful, lightweight machine with exceptional stability, specially designed to be easily transported without the need for special permits and in a single solution. Its small size makes it a perfect machine for work in areas with space limitations, but does not preclude its use on construction sites with large-diameter piles up to 1,300 mm and 5 m deep he configuration presented during the show is a CFA with maximum depth of about 15 m and diameter up to a maximum of 600 mm. Although it is the smallest model to date in the IMT range, it benefits from all the peculiarities of our high-end machines. Full load-sensing hydraulic system, which maximizes performance while saving fuel, layout that makes maintenance operations as easy as possible. The main winch has the function of automatically unwinding and stopping the rope while drilling. The rotary is equipped with a transmission derived from superior machines that means thousands of hours of maintenance-free operation, also features the same system that has always characterized our machines, unloading speeds above 90 rpm, so as to ensure fast cycle times, and possibility of unloading the tool with reversal of the direction of rotation at high speed.

The A70 is a powerful, lightweight machine with exceptional stability, specially designed to be easily transported without the need for special permits and in a single solution

A successful partnership The partnership between Sandvik and URI recently witnessed the delivery of a new DD311D jumbo, yet another machine added to the fleet of the company from Trento that currently boasts three DD311Ds and two Commandos

T

he partnership between Sandvik and URI, dating back more than 50 years, continues to everyone’s complete satisfaction and was recently confirmed by the purchase of a new single-boom hydraulic jumbo.

A TRULY EUROPEAN OPERATION After starting off in the explosives sector, URI has always been associated with drilling as a supplier of construction site, quarrying and mining materials, machinery and services with the name of the company from Trento linked to numerous infrastructure projects. “Previously a strictly local business”, explains Carlo Conedera, URI’s Head of Drilling & Foundation Technology, “we have become a national and European operation and our machines are at work all over

64

we are

drilling foundations

Northern Europe, in Spain, Austria, Germany and Switzerland. We specialise in drilling and foundations, but we are branching out, including into small drilling for civil engineering work. Therefore, renovation of existing structures, such as tunnels, or even the building of new tunnels and tunnel ancillary structures. In Italy we have contacts with all of the sector’s major players. These companies help us to step outside the domestic market, establish relations with foreign partners and even be involved in large projects. For example, shortly, one of our DD311Ds, along with a Comando, will be going to Madrid to repair a tunnel”. With a team of around 35, URI’s market is split almost equally between machinery and materials hire and sales for construction sites and services.

A PERFECT PARTNERSHIP

Andrea Iacolucci, Sales Manager Drilling Equipment and Rock Tools Italy, Balkans & Med di Sandvik, with Carlo Conedera, URI’s Head of Drilling & Foundation Technology

“We have a longstanding relationship with Sandvik”, Conedera continues, “dating back to the 70s. In the beginning we were Sandvik dealers in this specific area hen the relationship grew, Sandvik altered its business and so did we. Our current partnership with Sandvik regards drilling materials, but above all machinery. For us, it has become a strategic supplier as it offers unbeatable quality. Our choice of machinery is always a purely technical one: Sandvik machines offers high performance and we have been familiar with their drilling rigs, by which I mean drifter drills, for many years. These are extremely reliable drills that in recent years we have bought and also fitted to bespoke machines that we ordered.


In our opinion, when compared to rival products, they work much better, require less spares and have greater long-term reliability”. At the current time, the I hire fleet has five andvik rigs: a ommando 130, a Commando 300 and three DD311Ds. All Sandvik machines have been purchased over the last three years, the latest DD311D jumbo having been delivered in July.

DRY HIRE URI dry hires all Sandvik drilling rigs. A clear sign of the degree of user friendliness and the training skills of the staff of the Trento company that also provides technical support on its own. “Sandvik”, the URI manager continues, “has enabled us to train our staff, whilst the in-house skills mean that we have great familiarity with this type of machine and can perform maintenance throughout the entire life cycle of every piece of equipment. This in-depth knowledge enables us to supervise the training of our customers’ operators. Furthermore, the drilling rigs have enjoyed far greater technical and technological innovation than other types of machinery. They are modern and also slightly complicated to use, in that they have many automated features. We therefore need to be good at training the operators in how to use this type of machine safely”.

The DD311 single-boom jumbo can be used for both face drilling and ground improvement work

&Med joins the conversation, “is a machine that we manufacture and develop in France, at our factory in Lyon, and therefore the experts from the factory are also always very quick to provide assistance. Indeed, Sandvik is totally committed to supporting both URI and the end customers using the skills of those who actually manufacture the machine, as well as the engineers from Sandvik Italia. This proximity and the wealth of experience provided serve to facilitate problem solving”.

A VERSATILE MACHINE The Jumbo DD311 has three different versions: DD311, diesel-powered for translation and with electric power

for drilling 11 , powered by diesel for both translation and drilling and DD311DE diesel powered for translation and, optionally, electric or diesel power can be used for drilling. URI has made a choice of utility and versatility by choosing the diesel-only DD311D in order to satisfy those customers who operate on construction sites where power is difficult or impossible to find owever, this choice should not make you think of Sandvik as a manufacturer stuck in the past (indeed, Sandvik is also developing full electric models), but rather as a manufacturer capable of offering the correct solution for every situation. “It is quite easy”, Conedera advises, to find machines that build tunnels

SANDVIK SUPPORT Clearly, technical support is of vital importance for a hire company. “The DD311”, Andrea Iacolucci, Sandvik Sales Manager Drilling Equipment and Rock Tools Italy, Balkans

A history within history

The story of URI, acronym for fficio appresentan e Industriali, began in 1925 and is a tale of construction sites, quarries and large infrastructures that intersects and intertwines with Italian history, its complexities, its revival and the current difficulty in running an enterprise, in the noblest sense of the term. URI was founded by two young entrepreneurs from Trento, Count Giannantonio Manci

and Luigi Battisti, son of national hero Cesare. Manci and Battisti were subsequently partnered by Angelo Proclemer and Mario Agostini who took over the running of the business during the Second World War. These were the years of the reconstruction and URI was a supplier to businesses responsible for the great change taking place in the country. The challenge was that of the large infrastructures and

in its sector of operation URI took on a clearly international quality with regard to the construction site and quarry technology it offered. As time passed, URI helped to build bridges, roads and tunnels by providing increasingly hi-tech, safety-conscious machinery. A sector in which service, meaning efficiency, reliability, maintenance and consultancy, becomes a strategic value. Starting in

the nineties, hire became the company’s core business. The modern URI has three keywords: Reliability, meaning support and maintenance; Technology, meaning innovation and performance; Service, meaning the ability to solve problems. All this without forgetting the people, who were and remain at the centre of a corporate vision based on training, professional skill and expertise. we are

with the conventional system of progressing directly along the main tunnel face It is more difficult to find a machine that can create the niches. In many cases, tunnels require niches, cross passages and ancillary works that cannot be constructed directly by a conventional jumbo, they need machines that are slightly different. And this machine, the DD311, can do both things, it can perform the face drilling, but having a telescopic feed rod, it can be placed crosswise to the tunnel in order to drill through side walls and also perform ground improvement. When the tunnel requires bolting, this type of feed rod lets you move upwards and downwards in a radial pattern and carry out drilling for any ground improvement work”. In short, the DD311 is perfect for building small tunnels (the coverage area is 40 m2, i.e. 5.8 m × 7.2 m) and multiple applications inside tunnels.

System) drilling feed may be fitted that lets you oin two rods and bore more deeply. Another interesting option is the on-board Air Mist Flushing System, providing the machine with compressed air for drilling and water for flushing y fitting these optionals, the machine can be completely self sufficient without the need for cumbersome connections through the tunnel”. For the time being, URI has not chosen this option, but it is a device that can also be retrofitted “What is more”, Iacolucci notes, “if you need to perform maintenance in an existing tunnel, maybe only

open at night for these operations, the possibility of using a machine without electrical, water and air supply connections certainly represents added value”. Finally, by focusing on the machine in its standard configuration, it is certainly worth giving a quick mention to the 20 kW RDX5 rock drill. This rock drill, that has enjoyed considerable development over the years, is a reliable product with exceptional output and low maintenance costs.

THE TECHNICAL FEATURES “The question of the telescopic feed rod is particularly important”, Iacolucci advises. “Indeed, we can install two types of drilling feed: 6-12 feet (that chosen by URI) and 8-14 feet. The URI umbo can fit 1 m rods making it versatile in confined spaces: you can actually turn the feed rod even in a very small tunnel where it manages to drill very long holes. A TRS (Two Rod

The rig receives drilling data and drilling patterns that appear on the display and the cab operator can therefore see what type of hole he needs to drill. As it offers bidirectional information between office and machine, the T enables ful lment of re uests from ndustry and therefore, for the talian market, entitlement to the tax breaks available.
