Description

Special lifting appliance for large steel plate

Technical Field

The invention relates to a special lifting appliance for a large steel plate, in particular to a device which is adsorbed by an electromagnet and is convenient to lift by clamping the edge of the steel plate by a clamp, and belongs to the field of lifting tools.

Background

Generally, industrial and mining enterprises directly use steel wire ropes to hoist thicker steel plates. In the traditional hoisting method, more than two steel wire ropes pass through the lower surface of a steel plate, and then the ends of the steel wire ropes are tied to a crane hook for hoisting. In the hoisting process, the steel wire rope is worn at the edges and corners of the edges of the steel plate, so that strand breakage is easy to generate, and the service life of the steel wire rope is shortened. And because the stress direction of the steel wire rope stress point at the edge of the steel plate is inconsistent with the hoisting direction, the generated resultant force makes the steel wire rope move towards the middle direction, so that the abrasion of the steel wire rope is accelerated, the steel plate suspended in the air is unstable, and the steel plate is easy to overturn and fall, thereby bringing great hidden danger to safety. Therefore, there is a need for a lifting device that overcomes the above-mentioned shortcomings, can effectively avoid the abrasion of the steel wire rope and the strand breakage, and can stably lift and transport the steel plate.

Currently, there is no such device available on the market.
