ABSTRACT:
A mobile crane in which the front section of a lower carriage is provided with first fluid storage container, and in which an upper carriage has a first end section with an operator's stand and a second end section with second fluid storage container. A pump is provided which is operable by motor which may also form at least a part of the drive for the crane. This pump is adapted to pump fluid from the first fluid storage container to the second fluid storage container to serve as counterweight during hoisting operations of the crane. When the crane is to be moved over roads, the fluid from the second fluid container can selectively be released to the first fluid container for equalizing axle loads.
