摘要：
A hoisting mechanism comprises a pole (1) with weight and build-up branches (2, 3) and carrying elements (4) in these branches (2, 3), and a mechanism (6) for moving the carrying elements (4) in the branches (2, 3) from one such branch to the other. The mechanism (6) includes a hydraulic cylinder (8) with two pins (12, 13), two pairs of pivotable stops (17, 18), a guide (30), and two pushers. Axes (19) of oscillation of the stops (17, 18) are positioned in their centers of gravity, whereas the guide (30) has the form of an oval cup (31) secured to a housing (7) of the mechanism (6), has a slot (33) in a bottom (32) and holes (37) in the side wall to receive the push. ers.
