A new Liebherr LHM 600 Mobile Harbor Crane has been in operation in the Port of New York and New Jersey since November 2019. Metal recycler Sims Metal Management places its LHM 600 on a floating barge, which offers the company various advantages.Firstly, the barge solution offers enormous flexibility in terms of location. The company operates two different terminals in the New York Harbor. In addition to a terminal in the Port of Newark Sims Metal Management also operates the terminal of Claremont in Jersey City, N.J., which is about 10 kilometers linear distance.

Growing interest in hybrid-electric power systems is expanding the search for new propulsion and energy-storage systems in the workboat sector, where compliance with emerging environmental regulations and a relentless pursuit of operational efficiency are driving change. To meet demands for cleaner more efficient power, owners are examining the potential for less conventional methods of energy generation and storage – such as fuel cells, lithium-ion batteries, super-capacitors, flywheels, wind and solar – to propel their vessels.

Last September the test bed in Rostock was the stage of a single lift of the RL-K 7500 subsea crane. The same crane was then loaded and shipped to the South Korean customer. On December 21, a new Liebherr RL-K 7500 started its long journey to South Korea. after waiting since the middle of September for its shipment at the pier of the Liebherr factory in Rostock. Mid-December, the transport ship arrived at the Liebherr factory, and the RL-K 7500 was loaded aboard together with another model of Liebherr’s range of knuckle boom cranes, the RL-K 4200.

RL-K 7500 Subsea Crane

During customer days at the production plant in Rostock in January 2013 Liebherr presented its new subsea crane, type RL-K 7500. With this new knuckle boom crane the company extends its range of offshore cranes for subsea operations. The RL-K 7500 is able to lift up to 260t in the air and handle loads down to a water depth of 3,400m. The maximum rope diameter is 100mm, the maximum overturning moment of the crane is 75,000kNm. Depending on customers’ specifications, the boom configuration allows for working radii of up to 50 m.

Liebherr has announced the industry’s first hydraulic hybrid drive for mobile harbour cranes. The new Pactronic - hybrid drive system addresses two critical issues: increasing handling performance and reducing fuel consumption. The Liebherr Pactronic is a new hydraulic hybrid drive system. It is characterized by an energy storage device. A hydraulic accumulator supplements the fluid pump in delivering power to the system. It serves as a pressure storage reservoir incorporating a gas in conjunction with a hydraulic fluid. Energy is stored in this compressed gas to be released upon demand.
