Boom upgrade kit for Liebherr LR1600/2

Liebherr has introduced a boom upgrade kit for its LR 1600/2 crawler crane which increases lifting capacities by up to 20 percent and extends the heavy duty lift height.

The new SL-10 system adds 15 metres to the main boom lift height and when combined with 12 metre fixed jib takes the maximum hook height to over 160 metres at which it can still lift 71 tonnes.

A more direct comparison with the standard boom system shows an increase in capacity from 77 to 92 tonnes at a hook height of 147 metres. The boom kit allows the crane to erect the latest generation of wind turbines with tower heights of up to 150 metres. The derrick system has also been improved to allow the longer main boom and jib combinations to be erected.

As usual with Liebherr, this new system can be retrofitted to existing machines, with the owner only requiring a few additional lattice sections, which can be combined with the existing standard lattice sections to form the new SL-10 system. The additional sections can be supplied as a kit, making them ideal for those who have more than one LR 1600/2 in their fleet. The new system does not affect the basic machine and also does not increase its transport dimensions.

Liebherr says that the new wind power system is the basis of an all-round upgrade of the LR 1600/2 involving the standard boom system being extended using lattice sections from the new SL10 system. The new boom ‘system’ carries the suffix H for Heavy.
