Description

technical field

[0001] The invention relates to a sling, in particular to a novel sling which can adjust the length of the hook chain according to the needs of use, and belongs to the technical field of slings. Background technique

[0002] A spreader is a device for lifting heavy objects in a hoisting machine. The most commonly used spreader for lifting items is a hook, and its related accessories include lifting rings, lifting suction cups, clamps and forks. Among them, the lifting suction cup, clamp and fork are used together on the crane, which can be used as a special spreader for a long time, and can also be used temporarily as an auxiliary spreader hanging on the hook to improve work efficiency. The spreader for grabbing bulk materials is generally a grab with jaws that can be opened and closed, and an electromagnetic sucker can also be used to absorb magnetic materials such as metal chips; the spreader for lifting fluid materials is commonly used for buckets and hang...
