Abstract

1,191,875. Jib cranes. G. THALIN. 24 Aug., 1967 [31 Aug., 1966], No. 39115/67. Heading B8B. A crane comprises a boom 1 having connected to it tie cables 2 and having mounted on it a member 6 engaging the cables 2 so that any tendency of the boom to deflect laterally is counteracted by the cables. The member 6 may be detachably secured to and movable along the boom and is in the form of a frame having side portions for engagement with the cables 2. In a modification, Fig. 3 (not shown), each side portion of the frame forms a slit through which the associated cable 2 extends.
