The new LR 1700-1.0 from Liebherr combines the benefits of economical transport of 600-tonne class crawler cranes with the performance of 750-tonne class lattice boom cranes and also features all the innovations of Liebherr’s crawler crane developments from the last few years.

Great mobility and compact dimensions

Liebherr has completely redesigned the base machine for the new LR 1700-1.0 based on the dimensions of the LR 1600/2. Its track width is slightly larger than its predecessor at 8.7 metres whilst the length of the crawler carriers has grown to 11.35 metres. The LR 1700-1.0 is available with Quick Connection as an option.

Another low-cost feature for operators of the LR 1600/2 is that a large number of equipment components from the predecessor crane can also be used for the new LR 1700-1.0. These include the S sections for the main boom, the luffing jib, the 600-t head, several winches, hook blocks, ballast slabs and the runner.

High performance for industry and wind power jobs

The basis of the high performance of the new 700-tonne crane is the new base machine, which delivers between 10 and 15 per cent more lifting capacity. Furthermore, the 3.5 metre H lattice sections at the bottom of the main boom significantly improve the lateral stability of the entire system.

The boom can be raised to a height of up to 198 metres, comprising the main boom at 102 metres and a luffing jib at 96 metres. These lattice sections enable the crane to be used in purely main boom mode with a length of up to 162 metres.

For erecting wind turbines, the LR 1700-1.0 can achieve a maximum main boom length of 165 metres using additional H sections. A fixed jib of up to 15 metres in length can be attached to this. The lifting capacities of the new crane in this area are on a par with the LR 1750/2 with SX system.
