Maximum mobility, performance and economy

The comment by Per Thorsen Christiansen says everything about the new LTM 1090-4.2. He is the Managing Director of Danish crane and heavy haulage contractor BMS A/S at its Aarhus branch. "When the concept and the technical highlights of the LTM 1090-4.2 were explained to me, I decided I had to have the first one of this new model.

The new 90-tonne crane from Liebherr convinced me straight away.

I'm delighted that the decision has come to fruition. The new 90-tonne crane from Liebherr impressed me immediately because it has a very long telescopic boom, is just 2.55 metres wide and can carry a great deal of ballast with an axle load of 12 tonnes. Furthermore, Liebherr has also incorporated its VarioBallast® and VarioBase® innovations on this model."

A real winner

The LTM 1090-4.2 is an economical all-rounder with high lifting capacities – so powerful that it exceeds every other 4-axle crane on the market with an axle load of 12 tonnes. Its boom length of 60 metres also places the LTM 1090-4.2 on the podium. And in terms of flexibility it is the clear winner of the gold medal: VarioBase® and VarioBallast® mean that the crane is extremely flexible.It wins the cup for economy thanks to its sophisticated, variable driving states: uniformly distributed axle loads of 10 tonnes, 12 tonnes or 16 tonnes ensure low cost mobility all over the world.

The result is massive benefits in terms of licensing and road permits. The wide range of storage boxes on the vehicle is another plus for the crane driver. The wooden chocks are perfectly stored between the outriggers which means less legwork to place them under the outrigger pads. At the rear of the vehicle there is additional space for lifting equipment which means that the crane carries everything it needs for the hoisting work.

VarioBallast® with mechanical adjustment

The LTM 1090-4.2 features the innovative VarioBallast® system which means that it can be operated with two different ballast radii: 3.77 metres or 4.71 metres. The ballast radius can be reduced by 940 millimetres quickly and easily using standard mechanically slewing ballasting cylinders to ensure that the ballast radius remains inside the outriggers. This solution is a major benefit on constricted sites.
