Problems solved by technology
[0002] At present, cranes are widely used in wharfs and storage yards to lift bulk cargo such as sand, ore, and coal. However, the current limit of the range of the crane boom is limited by four steel wire ropes to 30° to 75°, and at 75° When the boom bumps into the mechanical positioning, it will cause deformation of the boom. If you do not pay attention to continue to rise, it will break the boom, which has serious safety hazards and cannot guarantee production safety.

According to the limiting device disclosed by the invention, the structure is compact, and the limiting on the boom can be effectively realized, so that the safety and the reliability of the boom during working are guaranteed.
Description
technical field [0001] The invention relates to a limit device, in particular to a limit device for a boom of a crane, belonging to the technical field of cranes. Background technique [0002] At present, cranes are widely used in wharfs and storage yards to lift bulk cargo such as sand, ore, and coal. However, the current limit of the range of the crane boom is limited by four steel wire ropes to 30° to 75°, and at 75° When the boom bumps into the mechanical positioning, it will cause deformation of the boom. If you do not pay attention to continue to rise, the boom will break, causing serious safety hazards, and production safety cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a crane boom limit device, which has a compact structure, can effectively realize the limit of the boom, and ensure the safety and reliability of the boom when it is working. [0004] Accordi...
