Abstract

The invention discloses a lifting appliance used for hoisting a cargo boom. The lifting appliance used for hoisting the cargo boom comprises a cross beam, a first limiting piece, a second limiting piece, a third limiting piece and a fourth limiting piece, wherein the cross beam can extend in the first horizontal direction; the first limiting piece and the second limiting piece can be arranged on the cross beam in a spaced manner in the first horizontal direction; at least part of the third limiting piece and at least part of the fourth limiting piece can be arranged on the cross beam in a spaced manner in the second horizontal direction; and the first horizontal direction is perpendicular to the second horizontal direction. By utilizing the lifting appliance according to the embodiment ofthe invention to hoist the cargo boom, the safety for hoisting the cargo boom is improved, and the cost for hoisting the cargo boom is lowered.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a spreader for hoisting a boom. Background technique [0002] The existing hoisting method of the boom has potential safety hazards. Contents of the invention [0003] The object of the present invention is to provide a spreader for hoisting a boom in order to overcome the problems in the prior art. [0004] In order to achieve the above object, the present invention provides a sling for hoisting a boom, the sling for hoisting a boom includes: a beam that can extend along a first horizontal direction; a first limit A member and a second limiting member, the first limiting member and the second limiting member can be arranged on the beam at intervals along the first horizontal direction; and the third limiting member and the fourth limiting member As for the limiter, at least a part of the third limiter and at least a part of the fourth limiter can be arranged on the beam ...
