Heavy lift handling in ports

Harbour operators face ever-changing challenges in relation to the heaviest of load lifting operations. Development of the product portfolio continues to expand at Liebherr alongside the rising tonnages that need to be moved in harbours around the world.

Suitable for sea harbours and inland harbours, can be used for all goods and ship sizes whether mobile or permanently anchored, maritime cranes from Liebherr set new standards in heavy duty material handling. Technology in the area of port equipment can currently cope with 616 tonnes. To achieve this, two LHM 800-type mobile harbour cranes are required.

Advantages at a glance

Accurate statements regarding the life expectancy of a crane are only possible in conjunction with the frequency and type of deployment. Therefore, Liebherr assumes the toughest of conditions when designing the crane. Not only the crane structure but also all of the components meet the conditions for acceptance at the highest possible classification level.

With heavy lifting, precision crane movements are decisive. To position goods weighing many tonnes with millimetre accuracy, the crane operator must rely on the movement of the machine. The hydrostatic drive's electronic control system ensures direct translation of the commands from the joystick and controls into crane movements.

A Liebherr subsea crane (RL-K 7500) with a weight of 665 tonnes is lifted by two mobile harbour cranes (LHM 600) and a mobile crane (LG 1750) from the base pillar on the test bed onto the pier in order to prepare the RL-K 7500 for shipping.

Safety-relevant functions are distributed throughout the crane. On the machine and hardware-side, measures range from redundant angle senders and force measuring axes up to twin microprocessors.
On the software side, too, the crane can be upgraded with a wide range of systems that support safety. Among these are preventative systems to prevent overload, inclined lifting and swinging of the load. A wide range of machine and handling analysis modules enhance the offer.
