Material handling made easy

Thanks to their robust design and the high line pull of the main winches, duty cycle crawler cranes from Liebherr are ideal for jobs using heavy grabs.
During operation with material handling grabs, the stabilizing winch with constant tension and free-fall prevents swinging of the grab and ensures exact positioning of the material.

Service life

Duty cycle crawler cranes must endure especially high dynamic stresses during dragline operation. Their robust steel construction not only increases the performance but also extends the service life making them perfectly suited for material handling operation.

Dragline control

The Interlock control system allows for power regeneration in dragline operation. This reduces the fuel consumption as well as the wear of the free-fall winch.

Transportation

Special attention was given to the uncomplicated and economic transportation on all roads in accordance with current international transport regulations. Thanks to minimum set-up work the machine can be quickly mobilized between jobsites so promoting economic deployment.

Sand quarrying in Australia: 400 t/h

The HS 895 HD - duty cycle machine with two 350 kN winches - is handling 400 t of sand per hour. With a swing angle of approx. 180° it requires only 45 seconds per cycle. The digging depth has been increased to 40 m.

The grab, with a filling capacity of 5 m³, can optimally penetrate very hard soils or interlocked material thanks to the specifically rounded shape and the grab teeth.

Stone-laying

Stone blocks are positioned with the aid of a mechanical or hydraulic orange peel grab in the construction of breakwaters or harbour facilities.

Looking to the future

Traffic jams, smog, crowding in the metro. The transport network of the French capital is completely overloaded. The infrastructure project Grand Paris is intended to prevent gridlock. Liebherr construction machines help to improve the connection between Paris and the surrounding suburbs. Find out here, how demanding the work in the middle of this densely populated metropolitan area is.
