Abstract

The invention discloses a lifting hook interval adjustable lifting appliance, which comprises a lifting head, a sling, a balance plate, a lifting hook chain and lifting hooks, wherein the sling is used for connecting the lifting head with the balance plate; the lifting hook chain is used for connecting the balance plate and the lifting hooks; a linkage mechanism is arranged in the balance plate, and is controlled by an external hydraulic system; and the linkage mechanism can make the lifting hook chain slide under the drive of a slide block so as to fulfill the aim of regulating the intervals of the lifting hooks. The lifting hook interval adjustable lifting appliance is reasonable in structural design and convenient to use; the distance between the lifting hooks in the lifting appliance can be adjusted according to use requirements, the moving and positioning of the lifting hooks are controlled by the hydraulic system, the operation is quick and accurate, the goods lifting stability is effectively improved, and the lifting appliance is suitable for lifting parts in various specifications.

Description

technical field [0001] The invention relates to a sling, in particular to a novel sling which can adjust the distance between hooks 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 hangin...
