ABSTRACT:
An apparatus for angularly displacing and/or moving a load suspended by ropes, comprising a lifting carriage frame running along a girder carried on running wheels, and rope sheaves for the lifting ropes. In lifting and transporting apparatus of prior art, fine adjustment of the load position was not possible. The problem has been solved with the aid of this invention in that the frame carries a running surface for each rope sheave set, and that the rope sheaves can be moved either together or separately with a separate moving machinery.
