Manipulator Tool for Offshore Cranes
The Liebherr offshore crane division has produced and delivered a new manipulator tool with a safety working load of 100t. Using this special equipment will extend the task the company’s offshore cranes can complete in service.
Providing reliable machines and safe working conditions is quintessential for an equipment manufacturer. To underline this approach, Liebherr designed a manipulator for its ram luffing knuckle boom crane series. This series is used for both deep-sea operations and pipe handling. Manipulator 100 is able to be used with either hook or crossbar function. The crossbar mode perfectly matches to any operation, especially to those under bad weather conditions or to emergency operations. It can be used for swing-free liftings of bigger components such as flotation devices of several dozen tonnes. These devices prevent the loss of equipment like pipes and cables underwater.
Next to the crossbar mode the manipulator can be used for more efficient material handling onboard. Load handling is restricted because conventional main and auxiliary hooks can’t rotate. This makes lifting of loads within limited space very difficult. The Manipulator 100 is able to fill this gap due to its 360° rotatable structure. Additionally it is equipped with a 2m long hydraulic telescoping arm. In this way the manipulator ensures an optimised working range and is an ideal tool for pipe handling operations for example.
