Abstract

The folding crane jib comprises two or more sections hinging together, the rear one also hinging on the crane towr, and folds and unfolds by a system of struts and ropes. A main strut (4) is attached to a rear hoist rope (6), and also to a tie rope (18) on the rearmost section (13) of the jib (2), while a second strut (8) is also attached by further tie ropes (30, 33, 33a, 41) to the other one (15, 16) and also to components (20, 9) holding it at an angle to the main strut in the direction of the forces exerted when working. These components secure the second strut to the tower so as to form a supporting arm, thus allowing the main strut to swing freely in relation to the second strut when folding and unfolding. Means are provided for adjustment of the outer jib section supported on the second strut.
