SENNEBOGEN’s “Gentle Giant” at Home in Turkey
The world’s largest purpose-built material handler, a 420 t giant unveiled at Bauma 2019, recently joined the ranks of working port machines. The SENNEBOGEN 895 E Hybrid was commissioned for the Tosyali Holdings fleet, at the Mediterranean port of Iskenderun, Turkey.
Since then, the machine has been moving massive amounts of scrap metals around the clock, every day. Electrically powered, the machine never needs to take a break for refueling. As one observer noted, walking near the 895 conjures images of Jurassic Park, where tiny humans tread lightly past peacefully gracing brontosaurs. But this gentle giant is real.
Everything about this machine is big and record-breaking. A convoy of 16 trucks transported the machine to Turkey. SENNEBOGEN’s distributor, Forsen Machinery, required just a few days to assemble its crawler platform, configure the set-up for Tosyali, and test run the 670 hp (500 kW) drive. Fitted with a 9,9 m3 orange peel grapple, it can reach out to 40 m to grab 10,9 t of scrap on every bite from the holds of panamax and post-panamax ships. Its operators move quickly, perched in the highly responsive and accurate elevating Skylift cab as much as 22 m above ground level. With SENNEBOGEN’s industry-leading hydraulics in hand, it allows for surprisingly quick cycle times.
“We handle 10,000,000 t/y in this port alone,” says Harun Karaarslan, Tosyali’s technical port director at Iskenderun. “Our machines are in constant use. We rely on our fleet to be producing constantly – downtime would be fatal.”
The 895 material handler, of course, does not produce all that throughput alone. Tosyali’s facility operates a total of 7 material handlers, including 2 SENNEBOGEN 880 EQ balance cranes also running on electric power. These machines, said Mr. Karaarslan, were a big part of Tosyali’s confidence in moving up to the 895.
The Green Hybrid energy recapture system engineered into the 895’s boom hydraulics greatly reduces the energy consumption. A pair of large hydraulic cylinders are mounted to either side of the main lifting cylinders. On each downstroke of the boom, the Green Hybrid cylinders hydraulically compress the gas in the storage modules at the rear of the upper carriage. On the next lift cycle, the compressed gas is released to give the lift cylinders a power assist, effectively offsetting the boom’s own weight, much as a compressed spring generates energy when it is released. As a result, the recapture system saves up to 55% of the energy for every lift, all day long!
