Bearing crab with swivellable jib

摘要

A bearing crab which can be moved on the rails of a suspended monorail laid underground is provided for transporting bulky and heavy loads in underground mountain and tunnel construction. This bearing crab has jibs which are arranged swivellably on the side walls of the bearing crab. For this purpose, a carrier which is assigned to the side wall and the jib which is constructed in a fork-shaped manner are connected to one another via a perpendicularly arranged bolt. The two jibs are coupled to one another via a connecting arm in such a way that they are each involved in the reverse swivel movement so that the heavy, bulky goods carry out the necessary movement continuously and uniformly when going around bends. <IMAGE>
