Before using the horizontal steel plate lifting clamps, the worker needs to check the wear and deformation of the lifting and register the inspection result on the inspection record. Lifting should be free of cracks, sharp angles, burrs, corrosion, warping and torsion. And to ensure that the rotation of all the rotating parts of the horizontal lifting steel lifting clamp is flexible, the fasteners can not be loose.
If the transverse lifting steel plate lifting clamp appears to be worn by the force member, the corrosion reaches 10% of the original size, or the jaw opening is increased by 10% compared with the original size, it must be scrapped and not used. Horizontal lifting clamps can only be used for horizontal lifting of steel plates, and other uses are strictly prohibited. Before use, according to the length and width of the steel plate, different horizontal hanging clamps are used for the lamination. If lifting a long number of iron plates, use a fixed beam lifting clamp.
The horizontal steel plate lifting clamps shall not collide with other objects during lifting. The lifter must assist the crane driver to do the reminder work for the direction of the object to avoid accidents. No lifting clamps shall be used beyond the rated load. Keep in mind that no matter which kind of lifting clamp is used, it must be clamped in accordance with the instructions and procedures, and it can be lifted after confirming that it is locked.
