When Iwamoto Metal Co Ltd's earthmoving excavator, which had been converted for material handling, had to be replaced, it was clear that the new machine had to be more powerful and at the same time generate lower operating costs. The new material handler is custom-made and perfectly adapted to the handling conditions on site: a SENNEBOGEN 830 E with 4.5 m pylon elevation and 132 kW electric drive.
Material handlers instead of earthmoving excavators in metal recycling: with a crawler undercarriage, 4.5 m pylon extension and 132 kW electric motor, the machine is configured precisely for the handling conditions at Iwamoto Metal Co Ltd's largest plant.
Iwamoto Metal Co Ltd is a BIG PLAYER in Japan's metal recycling . Over 90,000 tons of metal scrap are processed every month at 11 scrap yards across the country . The trend is increasing, because the recycling expert is seeing an increasing flow of scrap, particularly from the automotive industry.
The higher influx of scrap means that the machines are subjected to higher loads, have to process more material in the same amount of time and use on-site space more efficiently. The new acquisition should play a key role at the site, loading the metal scrap delivered by trucks and feeding the 7 m high shredder . The decision to replace the previously used, converted earthmoving excavator with a machine that was specially designed for material handling in scrap and is perfectly adapted to the handling conditions in Eichigawa was all the easier for the company. Like a tailor-made suit that fits perfectly and is prepared for any use.
"When it comes to recycling and scrap handling, earth-moving excavators often reach their limits in terms of load capacity, engine performance and cooling," explains Takeshi Iwanami, sales representative at SENNEBOGEN's Japanese sales and service partner Sun Earth Co. Ltd.
The conditions in earthmoving are different from those in material handling : earthmoving excavators are designed to exert their force downwards, directly into the ground. Material handlers , on the other hand, are optimized for high reach heights with maximum payloads. In these areas, earthmoving excavators lack the necessary power.

ergonomic joysticks and a cab that can be raised by 2.7 m
The cargo handled also has a decisive difference. Earth material has a significantly lower density than, for example, aluminum, copper or steel scrap. Since less load capacity is required, the engines of earthmoving excavators are usually smaller. The consequence: there is a lack of performance and also the right engine cooling to be able to work reliably and sustainably in material handling. If material handling is operated with a material handler, the driver and operator can look forward to high engine and hydraulic performance. This is the only way to move heavy material safely and efficiently.
The 4.5 m pylon elevation and the 2.7 m cab elevation ensure an ideal view of the 7 m high shredder and the loading areas of the trucks.
In addition to these advantages, the material handler from Iwamoto Metal Co Ltd. shows that the more a machine is customized to the customer's needs, the higher its efficiency. In order to make a contribution to environmental protection and to reduce operating costs, the scrap recycler made a conscious decision in favor of a material handler with a 132 kW electric drive . The 4.5 m pylon elevation provides the best possible overview of the mountains of scrap up to the 7 m high shredder. Thanks to the cabin elevation, driver Hisao Sugino can see even the most remote corner with a maximum eye level of 10 m. This increases effectiveness, but above all safety on site.
A significantly better view, noticeably more power and precise control: driver Hisao Sugino is more than satisfied with the newcomer. For years, his employer has relied on the green machines "Made in Germany" at all of his locations and the cooperation with the SENNEBOGEN sales and service partner Sun Earth Co. Ltd. “We are glad that we chose the electric excavator. The machine performs far better than its predecessor and the running costs are significantly lower,” emphasizes Hiroshi Iwamoto, Managing Director of Iwamoto Metal Co Ltd.
