technical field

The invention relates to the technical field of hoisting equipment, in particular to a hook stabilization system of an endless chain winch and hoisting equipment.

Background technique

The hoist is a light and small lifting device that uses a drum to wind a wire rope or a chain to lift or pull heavy objects. The hoist can lift heavy objects vertically, horizontally or obliquely. The hoist is widely used in construction, water conservancy projects, forestry, mines, wharves and other fields because of its simple operation, large amount of winding rope, and convenient displacement.

For hoisting equipment including a plurality of winches, if the plurality of hoists are not synchronized, it is easy to cause the hook to tilt, and the tilt of the hook will cause heavy objects to fall off, resulting in a safety accident. In order to synchronize the multiple winches of the winch equipment, the following strict restrictions have to be imposed on the winch equipment: a. The multiple winches are identical to each other, for example, the reduction ratios and drum sizes of the multiple winches are identical to each other; b. The installation positions of multiple hoists must be close to each other, roughly at the same position, which will lead to inconvenient arrangement of multiple hoists; c. The diameter difference of the wire ropes of multiple hoists must be controlled within a small range, generally requiring the same batch d. The multiplier of the wire ropes of multiple hoists must be the same as each other; e. The control accuracy of the length of the wire rope released and retracted by the hoist is relatively high.
