Description

technical field

[0001] The invention relates to a hoisting device, in particular to a locking type hoisting device with simple structure. Background technique

[0002] In production practice, the assembly or transportation of heavy objects such as large parts and components needs to be hoisted with the help of a spreader, such as a crane or a lifting mechanism. During the hoisting process, the transported heavy objects need to be locked and fixed on the spreader to ensure the safety of the hoisting process.

[0003] Existing hoisting and locking mechanisms are generally commonly used bolt hoisting and locking mechanisms, gear hoisting and locking mechanisms and spring hoisting and locking mechanisms. For example, Chinese patent CN201325827 discloses a lifting device for an automatic locking hoisting device, which includes an upper beam and a lower beam. Vertical poles are symmetrically installed at both ends of the upper beam and the lower beam. Station installation bracke...
