HAMM HC Series Compact Rollers
Page 54 • September 7, 2022 • www.constructionequipmentguide.com • Paving Section • Construction Equipment Guide With the HC series, Hamm is launching a new generation of compactors on the market. With operating weights of 24,251 to 55,115.6 lbs. and a wide range of equipment variants, they can comply with an extremely wide range of requirements.
HC Series: New Generation of Compactors for Earthworks
Hamm is attending bauma 2022, where it will present the HC series — a new generation of earthwork rollers for all markets.
The compactors achieve a high level of compaction power while simultaneously achieving a reduction in CO2 emissions. The communication capabilities are new: All models in the HC series are “digital-ready” since they can be equipped with various interfaces for the digital construction site.
One Platform for All Markets
The manufacturer is bringing together the two previous compactor series from Hamm — the 3000 series (Tier 3) and the H series (EPA Tier 4/EU Stage V) — with the HC series on one platform together with models with an operating weight of 24,251 to 55,115.6 lbs.
The diesel engines comply with the regional requirements, and their power varies between 85 and 160 kW, depending on the weight. On all models, the drum width is 84.3 in.
In addition to the previously known sales variants, in future there will be CR machines with reinforced components for applications on difficult terrain and special equipment for applications on rocky ground. New Design
The HC series is recognizable from the new, athletic design and the view channel in the engine hood. A new frame concept also guarantees increased tank volume; in particular, in future, the heavy compactors will be delivered to the construction site with an 88.8 gal. fuel tank.
Impressive Compaction Parameters
In comparison to the predecessor models, Hamm has increased the compaction power. The manufacturer has increased the centrifugal force by up to 15 percent; and the static linear load is as high as 451.6 lbs/in.
There are even innovations when it comes to the steering: A new cast articulated joint with articulated joint lock allows for a greater steering and swing angle with improved kinematics. Due to the optimized weight distribution in combination with the traction control, the gradeability also has been further improved. Furthermore, the front vehicle and the scraper have been redesigned. This has resulted in significantly increased clearance on the drum, meaning that no material can accumulate there, which eliminates cleaning work.
Great Power, Economical in Continuous Operation
Due to new approaches in machine management, the HC series achieves increased overall performance. The integrated ECO mode supports the operator so that they can work in the economical partial-load range as often as possible, which reduces the need for cooling. The speed is reduced for this — but, due to a large travel pump, without compromising the power.
This concept saves fuel and reduces the noise and exhaust gas emissions. With the optional engine stop system, the energy consumption can be reduced even further.
Comfortable Workstation Hamm also has again increased the operator comfort: The cab offers the operator over 20 percent more tread, around 30 percent increased space and numerous storage compartments. Furthermore, the vibrations and the noise level in the cab are significantly reduced due to the materials and design.
A comfortable heating and air-conditioning system, the Easy Drive operating concept, the innovative seat operating unit, the comfortable steering as well as modern ventilation round off the comfort.
Great Visibility During Day, Night
In the dark, the standard LED lights light up the environment in all working situations. At day and night, due to the view channel in the hood, the roller meets the requirements for the field of vision in accordance with DIN EN 474.
On the cab, a large additional mirror with proximity detection improves the view of the immediate environment, and design tricks guarantee low-vibration mirrors. Furthermore, the mirrors can be easily adjusted from the cab. Equipped for Digital Construction Site
The HC series is well prepared for the quality and communication requirements of the future. The “Smart Doc” app, which was developed by Hamm, graphically displays all of the key compaction parameters as well as the compaction progress, and logs the measured rigidity as well as the position data. In the Smart Doc app, even inexperienced drivers can immediately see which areas have been sufficiently compacted and which areas still require compaction. Furthermore, the compactors can communicate, even with digital applications from third parties, via a standardized interface.

Large slope angles and powerful drives guarantee that the compactors in the HC series achieve excellent compaction on uneven and steep terrain — even on inclines over 60 percent.

Wirtgen’s New Paving Train Makes Debut at bauma 2022
WIRTGEN from page 47
The concrete is poured evenly over the pre-placed steel rebar in front of the slipform paver and distributed across the entire working width. The SP 94(i) slipform paver then compacts and paves the concrete mix.
The paver at the show, which has a maximum working width of 32 ft., is fitted with a TeleMold system. It enables fast and convenient alteration of the working width by up to 3 ft. on each side, resulting in an overall increase of 6 ft. This increases the flexibility and productive utilization time of the machine by the reduction of down times.
The final link in the process chain is the TCM 180(i). This field-proven texture curing machine applies the desired finish to the surface of the freshly paved concrete. It enables the realization of lengthwise and crosswise textures and pre-defined surface roughness in accordance with project specifications. It also allows the application of a range of different curing agents to the concrete surface, for example a concrete surface retarder. year’s Bauma is the SP 124(i). The 4-track paver can be configured for paving at a working width of 39 ft. and fits seamlessly into the fleet-wide operating concept of slipform pavers from WIRTGEN.
The machine is fitted with the latest generation of the integrated dowel bar inserter. The dowel bars are extracted from the magazine by a chain feed system with an endless chain and automatically transported to the insertion location.
“Smart” cylinders with displacement sensors precisely position the dowel bar inserter at the desired locations. The high degree of automation reduces the proportion of manual work required, increases process reliability, and, ultimately, the cost-effectiveness of the process.
AutoPilot 2.0: Stringless
Control for Concrete Paving
Developed in-house by Wirtgen, AutoPilot 2.0 is a control system for stringless paving that serves as an alternative to the conventional method of mechanically scanning a stringline. The system, which precisely controls both the height adjustment and steering of the machine, is available for all offset pavers and placer/spreaders.
A GNSS signal and, depending on the configuration, various local sensors (e.g. an ultrasonic sensor on the machine), serve as a reference. The time and effort otherwise required for setting up and removing the stringline is eliminated. It also enables fast and precise paving of tight radii and complex geometries.
The system is conveniently operable from a tablet PC, which also supports the generation and editing of terrain models. Wirtgen AutoPilot 2.0 offers machine control and stringless control for concrete paving in one.

OSHA’s New Directive Only Revises Its Existing Operator-in-Training Section
OSHA from page 32
The evaluation must be conducted by an individual who has the knowledge, training and experience necessary to assess equipment operators. This knowledge, training and experience is not necessarily the same as the knowledge, training and experience to perform the particular construction operations or processes themself. Additionally, the evaluator must be an employee or agent of the employer.
Within the flowchart for crane operator evaluation, the key elements are: • “Has the operator been evaluated on the assigned equipment” • “Did the employer determine the evaluator is competent?” (If yes, please document) • “Did the evaluator determine the operator is competent to operate a crane which is similar to that assigned, and for a task similar to that assigned?” • “Does the required evaluation documentation include at least the six pieces of information specified?”
If the employer has not conducted the required evaluation(s) of the operator that serves as the basis for the operation of particular equipment for the particular task, then the operator is considered as an operator-in-training with respect to that equipment or task (see requirements for operators-intraining).
Multi-Employer Work Sites
For multi-employer work sites, OSHA states that “controlling contractors must exercise reasonable care to prevent and detect violations of the crane standard at the construction site.” OSHA goes on to say, “Controlling contractors assume a heightened duty to monitor an operator who is allowed on the site without providing evidence that the operator has been certified/licensed and evaluated in accordance with the crane standard… If the controlling contractor informs the other employers on the site that the crane operator has not provided evidence of certification/licensing, each employer could then take appropriate measures to ensure the safety of its own employees to fulfill its duties as an exposing employer.”
Additional Resources
OSHA also will be releasing the revised Small Entity Compliance Guide and Frequently Asked Questions related to this final part of the rule. In the last cycle these documents were released within a few months of the Compliance Directive.
Avoiding OSHA Citations
The best way to avoid citations by OSHA is to know and understand how the rule affects you, ensure that your operators and those around equipment are properly qualified, and that documentation is in order before OSHA asks. CCO will continue to monitor information released and assist in creating resources to assist the industry in compliance.
