A new barge-mounted Liebherr LHM 600 mobile harbour crane is proving its worth in the Port of New York/New Jersey.
Sims Metal Management, one of the world’s leading metal recyclers, took delivery of the LHM 600 in November 2019.
Because Sims operates two terminals in the port, the floating crane has provided the operator with a highly flexible solution. Depending on requirements, the floating mobile harbour crane can be towed by sea between Sims’ terminals at Port Newark and at Claremont in Jersey City, a linear distance of 10 km, and is thus ready for operation in the shortest possible time.
The crane can also move along the barge to reach further hatches without having to move the barge. Operation from a barge also means that no adjustments to port infrastructure was necessary. The space gained at on the quayside can thus be used as storage and operational space.
The Liebherr LHM 600 operated by Sims is equipped with a 750 kW Tier 4 final-compliant Liebherr diesel engine. The crane has a maximum lifting capacity of up to 144t. In four-rope grab operation, a capacity of up to 75t is available, making it the most powerful mobile harbour crane operating on a barge in the US.
The Liebherr Pactronic hybrid system is installed as an additional power booster in the new machine. Its main feature its accumulator, an additional energy storage device. The accumulator is charged when the load is lowered and by surplus power from the conventional drive unit. Both lifting and lowering speeds are significantly increased despite the primary power output remaining the same.
Sims is also benefitting from Liebherr’s LiDAT smartApp software, an IT solution for the analysis and optimisation of cargo handling processes.
