Description

Self-locking pliers, assigned for gripping for the purpose of lifting and carrying cargo, usually represent a pair of crank-type broken-linear, cranked, etc., newly-rotated arms in the frame, which seize the load with their lower ends, fitted with hooks or claws, and the upper ends are hinged with a heavy head under the hook of a crane. The proposed pliers for cargo are mainly in soft containers — they are of the indicated type, differing in the use of a spring latch, which automatically closes the pliers in the opened state before the seizure of the cargo and after lowering it.

In FIG. 1 is a front view of a tick with a partial cut; FIG. 2 - side view; FIG. 3 - top view.

The device proposed ticks is. On the hinges 6 at the ends of an elika / pivotally fixed two bend bent levers. Their lower knees 15 are branched in two for better gripping of the cargo and are equipped with: ryukchkas or claws 7, tipping 3 soft containers of cargo, and the upper knees 16 are made of two parts, which are moved apart

along the length and fastened with a collar 19 in order to be able to change the size of the opening of the pharynx ticks. Beam/. podlitsya to the hook of the crane through the head 26, with which the ends of the knees 16 are hinged by means of earrings 22. At the center of the head is fastened to the thread and nut 29 vertical rod 27, freely passed through the sleeve 2 in the middle of the beam. At the top, this rod has a gash 8 for putting on a crane hook, and in the lower part of the rod there is a nest 5 (Fig. 2), which may include a latch 3, equipped with a spring 4 and a handle 33.

When the latch is pushed into the socket, the tongs are in the open position shown in FIG. 1 drawing flat lines. In this form, the pliers are lowered onto the load to be gripped and lifted, and then the latch 3 is pushed onto its handle by an action. Then the rod 27 and the head 26 are allowed to lift. Under the action of the initial weight, and then when the load is lifted from the tension of the crane load rope, the knees 15 of the arms compress the load and their claws 7 are thrust into the soft container. This position is shown in the dashed drawing.
