Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a European-style electric hoist with an anti-falling structure. Background Art

[0002] The European crane is a gantry crane with light weight, compact structure and low energy consumption. A trolley and a lifting mechanism are set on the bridge. The trolley can run forward and backward, and the carriage can run other mechanisms to realize the transportation of materials in three-dimensional space. The electric hoist is a special lifting equipment installed on the overhead crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and easy use. It is used in industrial and mining enterprises, warehouses, docks and other places. When the crane drive equipment fails, the hoisted goods will cause the crane's winding mechanism to stall and rotate due to its own weight, and fall, which has a great impact on the life safety of the operator.

[0003] A suspended European-style electric hoist disclosed in the Chinese utility model patent application disclosure CN209922734U is convenient for lubricating the wire rope, thereby increasing the service life of the wire rope, and is convenient for adjusting the angle of the hook. It is also convenient for fixing the hook to avoid the hook from rotating during operation. However, the suspended European-style electric hoist has the disadvantages of low safety level and lacks the function of preventing the crane hoisting mechanism from falling. When the crane drive device fails, the hoisted cargo will cause the drive device to stall and rotate due to its own weight, and the cargo will fall. Utility Model Content
