ABSTRACT:
A lifting yoke for containers consists of a central beam (1) and two coaxial extending beams (2, 3) guided for reciprocating movements by the central beam and capable of telescoping one into the other. A guide tube (4) arranged coaxially inside the extending beams is able to connect them together when they are extended one from the other and to guide one of the beams into the other when they are telescoped one into the other. The telescoping mechanism (5) for the lifting yoke consists of a hydraulic cylinder (9) with driving wheels (10), two pulleys (11, 12), a cable (13) running over the driving wheels and the pulleys, and protruding rods (14, 15) attached to the cable for operating the extending beams (2, 3).
