摘要:
A device for hoisting and lowering a load comprises driving (13, 14), coupling (5, 6) and winding means (1, 2, 3), wherein at the start of the hoisting operation, the driving means (13, 14) and the coupling means (5, 6) undergo an axial displacement relative to each other such that a coupling between the driving means (13, 14) and the winding means (1, 2, 3) becomes possible thereby, and wherein at the start of the lowering operation, an uncoupling between these driving means (13, 14) and the winding means (1, 2, 3) is effected. A locking member (16) is present for locking the coupling means (13, 14) before the driving (13, 14) and coupling means (5, 6) are axially displaced relative to each other to enable a coupling between the driving (13, 14) and winding means (1, 2, 3), and for undoing this locking when the coupling is effected before the load is hoisted.

An apparatus for treating a hind leg of a four-legged animal, in particular a cow, the apparatus being provided with holding means for holding the animal, the holding means being provided with a retaining member extending, during use, at least behind the hind leg to be treated of the animal when this hind leg is in a standing position, the apparatus being provided with lifting means for bringing said hind leg from the standing position to a raised position for treatment and vice versa, wherein the retaining member (3), at least during use of the lifting means (5) for bringing the hind leg from the one to the other position, is arranged such that the retaining member (3) can only be moved substantially vertically.
摘要:
The invention relates to an apparatus (1) for supporting a leg (P) of an animal, for instance for the purpose of inspection or treatment. The apparatus comprises a supporting element (2) and a winch (5) for hoisting he respective leg (P) onto the supporting element (2). The winch (5) comprises a rotatable spool (8) with a drive element (12) for winding and unwinding an elongated element (6) that can be fastened around the leg. The winch further comprises blocking means for blocking the unwinding of the spool, releasing means for eliminating this blocking action and immobilizing means for immobilizing the drive element in at least the unwinding direction for as long as the blocking action of the blocking means (10) is deactivated.
