Abstract

The invention discloses a novel lifting appliance which comprises a lifting head, a balance plate, a lifting rope, a lifting hook and a curb chain of the lifting hook, wherein the lifting rope is connected with the lifting head and the balance plate; and the balance plate is internally provided with an electric winding device which is used for controlling the length of the curb chain of the lifting hook, so that the curb chain of the lifting hook can be elongated or contracted in a synchronous way. The novel lifting appliance disclosed by the invention is reasonable in structural design and unique in effects; the length of the curb chain of the lifting hook can be electrically adjusted according to the use demand; the novel lifting appliance is convenient in operation and implement and high in accuracy; after being adjusted, the curb chain of the lifting hook is automatically locked, so that the work stability of the novel lifting appliance is excellent; and the novel lifting appliance can be matched with a bearing plate for use, thus being capable of lifting parts with various sizes and specifications.

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...
