An attachment for stacker trucks in the form of a fork-arm or gripper adjuster, with a right-angled lifting frame (1) consisting of lateral cheeks (2) and a top and bottom supporting and guide tube (3, 4) connecting the cheeks as well as supporting beams (7, 8) held in such a way as to be displaceable in a sliding manner on the supporting and guide tubes (3, 4), accommodates tubular supports (15, 15'; 16, 16') in additional bores (13, 14), which tubular supports (15, 15'; 16, 16') are connected at their outer end to a fork arm (17, 18) or gripper element. The other respective end of the tubular supports (15, 15'; 16, 16') is provided with a stop (23) and can pushed free of contact through an additional recess (25) in the other respective supporting beam (7; 8). The fork arms (17, 18) can be displaced from a retracted position centrally in front of the lifting frame (1) into a position well outside the lifting frame (1) by the exclusively tubular guides with slight expenditure of force via piston/cylinder arrangements (19; 20). <IMAGE> |
