Derrick and ballast systems

Using a suspended ballast systems makes your crawler crane much for flexible. Technically quite easy to explain, the suspended counterweight tray features a hydraulically telescoping guidance to increase the radius of the counterweight even under load. This increases the load capacity of the crane.

With a small radius the derrick ballast will adjust perfectly to a constricted working environment. If there is adequate space available, on the other hand, the increased radius enables ballast weights to be saved.

If you need to travel longer distances with the load on the hook, the ballast wagon is an option to look into.

The 750-tonne LR 1750 is moving prefabricated concrete components. The suspended counterweight tray with hydraulically telescoping guidance increases the counterweight radius.

For heavy loads, the comfort class and heavy lifting LR cranes can be fitted with a derrick boom.

The radius of the suspended counterweight can simply be hydraulically displaced by the operator.

Our LR 1800-1.0 features a new type of ballast system – the V-Frame®. This is a hydraulically adjustable folding frame. It enables enormous adjustment distances between 14 and 23 metres. That delivers maximum flexibility compared to the standard rigid system for large ballast radii.

With good job planning, the V-Frame® creates an enormous range of uses and makes it possible to dispense with ballast transport.

The ballast wagon allows the crawler crane to move or turn with the load on the hook without the complete change of the attached ballast. This is the big advantage compared to the suspended ballast where the ballast must always match precisely the beforehand calculated load.

We offer different ballast wagon solutions for our different sizes of LR crawler cranes. Check out some crane jobs with ballast wagon in use.

The ballast wagon for the LR 11000 features a whole host of railings and access ladders to ensure the safety of the operating personnel.

A Liebherr LR 1750 crawler crane with ballast wagon dismantles a motorway bridge. Using the derrick ballast as a counterweight increases load capacity.

The ballast wagon for the LR 1750, shown here in driving position, can also be used on the smaller LR 1600/2. This benefits crane contractors who have both models in their fleet.
