Frame hoist for containers comprises top and carriage bottom frames linked by bolt-jointed telescopic bearers both sides with drive and pressure cylinders ensuring steady load handling.
Joint bolts (5,6) both sides of the top frame (4) and the carriage beams (3) are for telescopic bearers (1,1a,1b,1c) between frame and carriage beams, each bearer (1,1a,1b,1c) allotted a pressure cylinder (2) between respective beam (3) and securement. The spacing between top frame (4) and beams (3) varies parallel and normal and the carriage beams take load as the bearers and cylinder move at the same time. Both sides of the vehicle are pairs of criss-crossing bearers and their cylinders plus an allocated drive. A clamp between bearers (1 and 1c) adjusts in height at their intersection to keep the bearers clamped securely at all levels. The bearers (1,1a,1b, 1c) come in three telescopic parts (1,1a,1b,1c) with pulleys (9,17) on the bottom part (1c) for a return rope (12,13) and a further pulley (17) for the bolt (5) and pulley supports for the up and down movements of the pulley (9).
