SU461887A1 - Cargo hook - Google Patents

Description

This invention relates to lifting mechanisms.

Devices are known for automatically releasing a hook from a loop of a cargo lanyard, comprising a shaped brace mounted on the hook shank in the form of a freely hanging rod with a support bar and one, with the middle part of the bracket having a vertically spaced groove.

However, in such devices, the cargo sling loop is not securely protected from dropping the hook.

The purpose of the invention is to improve the reliability of the cargo hook.

This is achieved by the fact that the safety device is made in the form of a movable sleeve connected with a bracket with trunnions, on which there are levers locking the hook shed, which interact with the clamping with stops attached to the hook.

FIG. 1 shows a load hook at the time of lifting the load; in fig. 2 - the same, side view; in fig. 3 - the same when lowering the load. On the support.

A device mounted on a standard hook 1 consists of locking levers 2 pivotally connected to a movable sleeve 3 pins 4. The levers 5 for dropping are fixed to the movable bracket 6, the stops 7 and 8 are fixedly connected to the hook 1.

When working on the hook 1, two loops 9 of the sling are put on, for which the movable sleeve 3 is raised, and the locking levers 2, interacting with the stops 8, are folded, opening the mouth of the hook 1.

When lifting the hook, the movable sleeve 3 with the locking levers 2 and the basement hook 6 slides along the shank of the hook 1.

The locking levers 2, in cooperation with the stops 7, close the hook jaw, and the stops 8 do not allow the safety device to open.

When lowering the load and when the movable bracket 6 stops in the load, the hook 1 continues to lower, the base sleeve 3 slides along the hook shank, locking the levers 2, interact with the stops 7 and 8, fold, opening the hook shed and dropping the loop 9 of the line with lever 5.
