ABSTRACT:
A load-conveying apparatus provided with a load support device, a jib arm having the load support device mounted thereon and adapted to be swiveled relative thereto about a vertical axis, a guide frame having the jib arm extending therefrom in a cantilevered fashion, the guide frame supporting the jib arm for lateral movement along the guide frame in a generally horizontal direction, drive means for driving the jib arm along the guide frame, and stabilizing means for absorbing turning moments applied about a vertical axis acting between the jib arm and the guide frame. In accordance with the present invention, the stabilizing means include a moment-absorbing carriage having a length extending in the direction of lateral movement of the jib arm on the guide frame and being laterally movable on the guide frame in the lateral direction, movement limiters for limiting the range of movement of the moment-absorbing carriage on the guide frame between two opposed locations, and a sliding member having the jib arm mounted thereon and being displaceable along the moment-absorbing carriage to effect displacement of the jib arm relative to the moment-absorbing carriage, the sliding member having a length which is smaller than the length of the moment-absorbing carriage so as to enable sliding movement thereof together with the jib arm along the moment-absorbing carriage.
