Liebherr ltm 1220 – a crane you need to know more about!

The Liebherr 1220 mobile crane is structurally oriented to perform such tasks with which cranes of insufficient load capacity cannot cope. The total weight of this five-axis crane is 60 tons and is fully used to optimize the carrying capacity. With the help of the Liebherr crane with a lifting capacity of 220 tons, you will be able to perform the most complex lifting and construction work.

Modern drive concept

  1. Two-speed transfer case, designed to work in harsh conditions; lockable distributor differential; slow motion speed 0.72 km/h.
  2. Drive 10×6, bridges 2.4 and 5 leading.
  3. Drive 10×8 (on request); bridges 2.4 and 5 leading; the 1st bridge is connected when driving off-road.
  4. Cylinders of the suspension are free from the effects of lateral forces and do not require maintenance; the piston rod is protected by a plastic pipe from damage.

Braking decelerators: motor brake in the form of a brake system of a free-discharge valve with an additional brake system Liebherr ZBS, mounted directly on the gearbox, retarder.

Service brake: all bridges are equipped with pneumatic disc brakes, which have high braking efficiency, long intervals between maintenance operations, providing the possibility of quick replacement of brake linings.
