Abstract

A mobile crane has a mast (1) which is swung to the horizontal position with the boom (3) lying on top of it in order to facilitate transport. The ballast (10) is brought to a central position so that the crane as a whole is balanced on the base (8). When the crane is erected, a mechanism (11) connecting the mast and the ballast (10), automatically pushes the ballast outwards along guide rails. Thus, when the boom is fully extended, the ballast is in the correct position for counterbalancing the load being lifted.
