Through the Lens… ‘Equipment Manufacturers Make America’ Tells Story of Manufacturing in U.S.

The Association of Equipment Manufacturers (AEM), the North American based trade group representing off-road equipment manufacturers and suppliers, unveiled its Through the Lens: Equipment Manufacturers Make America photo series by documentary photographer Brad Romano.

Romano took more than 150 photos to help tell the story of the 2.8 million men and women of the equipment manufacturing industry in America. The photos were taken in April and May of this year on location at Bomag (Ridgeway, S.C.), Calder Brothers (Taylors, S.C.), JCB (Pooler, Ga.), Kubota Tractor Corporation (Jefferson, Ga.), LeeBoy (Lincolnton, N.C.), and Power Curbers (Salisbury, N.C).

The series will be highlighted through AEM’s national grassroots advocacy campaign, I Make America, as well as Facebook, Instagram and Twitter, throughout the rest of the year.

I Make America is made up of more than 40,000 supporters throughout the United States who are committed to advancing promanufacturing policies that help the $288 billion equipment manufacturing compete globally.

“Equipment manufacturers have a powerful story to tell and AEM’s Through the Lens: Equipment Manufacturers Make America photo series spotlights the critical work the 2.8 million men and women of our

SENNEBOGEN Delivers Increased Safety, Performance

Scrap Handlers Versus Excavators: Built for A Purpose

Iwamoto Metal Co. Ltd. has seen first-hand how a purpose-built scrap handler is better suited to their operation than a converted excavator. But why is the difference so pronounced? The key is the difference in purpose: one machine is built to lift heavy weights above ground, while the other is supposed to dig deep below ground level.

That difference in geometry means a lot to the engineers who design such machines. The stresses on the structural components are distributed very differently, so the parts are designed to handle different points of wear. When an excavator is forced to reach up very high with a full load, the weight is transferred to places that were never intended to carry it. The same is true when you mount a high-rise cab on an undercarriage that was not designed to stabilize such a top-heavy-structure.

Excavators generate massive break-out forces to take big bites into the earth. Their booms, hydraulics and power train are all built for that purpose. But these forces are not needed to swing a grapple or magnet load of scrap. Instead, the scrap handler is built for speed, to lift high and swing fast. The engine power and heavy frame of the digging machine are simply a costly energy drain in scrap handling tasks.

What the scrap handler really needs is smooth handling and dampening of the vibrations so operators can run non-stop for entire shifts without fatigue.

Outwardly, the two machine types appear very similar, but closer examination shows you how engineers recognize their different purposes. For example, on a scrap handler, the hydraulic stick cylinder is positioned on the underside of the boom, to power the stick upwards to the top of its lift range. The stick cylinder of an excavator, however, is located above the boom, allowing to leverage the stick and bucket down into the earth more efficiently. The scrap handler also is designed to support its counterweight while the counterweight on a converted excavator is added as an afterthought.

Both machines are built for a purpose. Choosing the machine that is built for your purpose will pay off in performance, uptime, efficiency and safety.

When Iwamoto Metal Co. Ltd. converted its excavator into a material handling machine, it proved to be a useful short-term solution. However, when it was time to replace it, the company knew that its new machine had to be more powerful and more efficient in order to reduce operating costs.

The solution was a custom-built SENNEBOGEN 830 E with a 15 ft. pylon and powered by a 180 hp (132 kW) electric drive motor that was purpose-built to meet Iwamoto’s material handling requirements on this site.

Iwamoto Metal Co. Ltd. is a major player in Japan when it comes to metal recycling. More than 90,000 tons of scrap metal is processed every month at 11 scrap yards spread across Japan. And with recycling experts predicting an increasing influx of scrap materials, particularly from the automotive industry, Iwamoto Metal Co. will only be busier as time goes on.

Modern Material Handler Replaces Modified Excavator in Metal Recycling

An influx of scrap means that machines are subjected to higher loads, required to process more material within the same time frame and every square foot must be used more efficiently.

Iwamoto Metal Co.’s new SENNEBOGEN acquisition will play a key role at the site, loading the metal scrap delivered by trucks and feeding the hopper of the 23 ft. high shredder. In fact, it was the reach and versatility that allowed for this decision to ultimately be an easy one.

Swapping out a converted earthmoving excavator with a machine that is purpose-built for material handling operations and has been customized for the material handling conditions at Eichigawa is like having your suits tailor-made… they fit perfectly and you always look your best regardless of the situation.

Explaining Differences

What are the differences between an earthmoving excavator and a material handler?

“Excavators often reach their limits in recycling and scrap handling in terms of load capacity, engine power and cooling," explained Takeshi Iwanami, product expert at SENNEBOGEN's Japanese sales and

Complete with its high-performance powertrain, closed-loop hydraulics and upgraded screening, the new Cat D1 mulcher is specially designed to optimize performance when clearing a mix of small- to medium-diameter materials.

Design-matched with the rugged Cat HM518 mulcher, the D1 mulcher clears a 72 in. wide strip on each pass, making it the right machine for right-of-way construction and maintenance, site development, tree management and firebreak clearing, according to the manufacturer.

The new mulcher is powered by the 77.6 kW (104 hp) Cat C3.6 Diesel Engine meeting U.S. EPA Tier IV Final/EU Stage V emission standards. An alternate emissions package for the C3.6 is available to meet Tier III-equivalent standards.

The machine’s lower sloping hood line improves visibility to the mulching head, allowing the operator to better assess the job site from the cab. Standard auto reversing fan purges debris from the radiator and enclosures, plus the hinged grill requires no tools to access the radiator for cleaning.

Isolating machine vibration from the operator to reduce fatigue, the Cat HM518 mulcher controls are mounted on the air-suspension seat. Inside the pressurized, heated and air-conditioned cab, an intuitive operator interface features a 10 in. color touchscreen monitor with standard reversing camera display to help improve all-around visibility to the jobsite. An in-cab drum indicator offers quick glance of drum speed and direction to help the operator manage ground speed and mulching productivity.

Featuring cladding material in high-wear areas, the new HM518 mulcher frame offers increased service life. Bolt-on wear plates deliver long wear life and are quickly replaced.

Offering a drum speed range of 2,150 to 2,450 rpm, the drum’s 38 fixed teeth feature a single-bolt carbide tooth retention design for simple replacement. Its closed-loop hydraulic circuit includes load-sensing hydraulics to prevent rotor damage when hitting an obstruction.

The HM518 mulcher has a 31 in. maximum lift height, 14.5 in. maximum tilt and 25degree maximum angle to either side.

Standard sweeps, screens, windows plus rear guard help to protect both the operator and machine when mulching. With its specially designed tractor platform, the D1 mulcher is balanced and rugged to increase efficiency when operating in challenging applications.

Contractors can choose between the conventional (XL) or low-ground-pressure (LGP) undercarriage design, offering 16 in. or 25 in. track shoe widths respectively, to increase flexibility and efficiency for working in soft underfoot conditions, on slopes and in rough terrain. To increase machine versatility, the new D1 mulcher can be equipped with an optional variable-pitch/angle/tilt (VPAT) blade in XL, LGP or Intermediate configuration.

The 15 ft. pylon and the hydraulically raised 9 ft. Maxcab provides ideal visibility into the 23 ft. high shredder.

service partner Sun Earth Co. Ltd.

Conditions in earthmoving differ from those in material handling: earthmoving excavators are designed to exert their force downwards, directly into the soil. Material handlers are designed to reach high heights with maximum payloads. In these situations, excavators don’t have the necessary power or reach to maximize their onsite performance.

Increased Performance Through Customized Configuration, Electric Drive

In addition to being right-sized, Iwamoto Metal Co. Ltd.’s 830 E Series material handler continues to showcase the SENNEBOGEN philosophy that the more a machine is customized to the customer's needs, the more efficient it is. Furthermore, in order to be environmentally responsible while also reducing their operating costs, the company chose a SENNEBOGEN material handler with a 180 hp electric drive powerplant.

The 15-ft. pylon elevation provides the best possible view of the scrap piles being loaded on to the infeed deck of the 23 ft. high shredder. Due to the hydraulically raised Maxcab, the operator has a clear view of even the most remote corners from his vantage point now being 32 ft. This increases his efficiency while at the same time, reducing the risk of any accidents related to visibility challenges.

With a much better view, noticeably more power and precise control, the operator is genuinely pleased with the new machine. "We are glad that we decided to go with the electric material handler. The machine performs much better than its predecessor and the operating costs are much lower," said Hiroshi Iwamoto, managing director of Iwamoto Metal Co. Ltd.
