The quick replacement device has the beneficial effects that the quick replacement on the lifting hook can be realized, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lifting heavy objects, in particular to a fast hook replacement device. Background technique [0002] Cranes must use hooks to hoist goods. In many hoisting workplaces, the same crane needs to hoist many different goods. These goods are of different sizes and shapes, so it is necessary to replace the crane hooks to adapt Different goods, but the current crane hooks are mostly connected with the main body of the crane through threads, the operation speed is slow during the reloading process, resulting in low efficiency of lifting goods, so some crane staff and crane manufacturers hope to have a A crane hook device that can be quickly replaced can be quickly replaced when different items are hoisted, thereby improving the hoisting speed and work efficiency. Contents of the invention [0003] In order to solve the above problems, according to the structural characteristics of the sling, the present invent...
