Description

Technical Field

[0001] The utility model belongs to the field of hoisting, and in particular relates to a steel plate hoisting tool. Background Art

[0002] The material transportation track system at the production site has a large number of 20mm thick steel cover plates, and the on-site trenches that need to withstand the passage of larger vehicles or personnel have thick steel cover plates. However, the covers need to be lifted open during equipment maintenance and trench cleaning operations.

[0003] At present, when lifting thick steel plates and other large objects, most of them are lifted by clamping the edge of the steel plate with four clamps, or lifting the steel plate with a magnetic disk; and some narrow and long steel plates are lifted by tying them with ropes. These lifting methods have many inconveniences. For example, whether using clamps or ropes, you need to find a way to pry the steel plate off the base surface with a crowbar before lifting, so that the clamps and ropes can pass under the steel plate for operation, which poses a safety hazard; lifting the steel plate by magnetic disk also has the safety hazard of the disk suddenly losing its magnetism and the steel plate falling.

[0004] Therefore, there is an urgent need to design a safe and convenient steel plate lifting tool for lifting cover plates made of thick steel plates to reduce safety risks and the occurrence of safety accidents. Utility Model Content
