March 21 - At the port of Bremen, Germany, Ulferts & Wittrock has assembled a Liebherr LPS 280 portal slewing crane for handling scrap metal, utilising a Liebherr LTM 1500-8.1 mobile crane for the heaviest loads.

The crane manufacturer says its Liebherr LPS series portal slewing cranes are handling machines with a small footprint and are therefore mainly used where space is at a premium, making the assembly of the machines, which weigh hundreds of tonnes, an even bigger challenge.

Heiko Ramke, from the external technical service team for large cranes at Ulferts & Wittrock, explains: "The size of the area available meant that it was not initially possible to assemble the portal slewing crane on the rails.

"Initially the travel gear supports were assembled with the cross carriers and this total load of 115 tonnes was then moved around 2.5 m by three cranes, the 500-tonne LTM 1500-8.1 and two 200-tonne machines, then hoisted onto the travel gear which had already been placed on the rails."

Two weeks later the portal crane's boom was assembled during a tandem hoist by a 130-tonne and a 160-tonne mobile crane.

Ulferts & Wittrock is a sister company to Ulferts and the Wittrock Group which provides a complete range of services for mobile crane and heavy haulage logistics, heavy assembly work, company relocations and the rental of work platforms, telescopic handlers, forklift trucks and miniature cranes.
