Overall concept designed for simplicity and economy
The new Liebherr crawler crane cannot just be transported easily and at low cost, but is also simple to set up and operate.
The powerful main hoist gear with its rope hoist of 180 kN can handle all hoists up to the maximum load capacity. This makes crane operation easier since it means that there is no need for a second winch for dual operation for heavyweight hoists. Another winch with a rope hoist of 125 kN is only needed if the crane is operated with a runner.
The designers also developed the whole lattice boom system to be simple. They reduced the number of parts and parts range on the new LR 1500 by deliberately not using the otherwise standard divisions of lattice elements. That makes the transport and erection of the lattice boom simpler and therefore more economical.
