The vertical plate lifting clamps must be familiar with the safety operation rules before use. To a certain extent, the wear and deformation of the lifting equipment should be checked, and the inspection results should be registered on the inspection record. The lifting should be free of cracks, sharp angles and burrs. Harmful defects such as corrosion, warpage and torsion. Whether all of the rotating parts are flexible or not, the fasteners cannot be loosened. If the section of the stressed member is worn, 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 must not be used.
vertical plate lifting clampss can only be used for horizontal lifting of steel plates, and other uses are strictly prohibited. To a certain extent, according to the length and width dimensions 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. For lifting short or single steel plates, no fixed lifting clamps can be used. No matter which lifting clamp is used, only the pair can be used, and the thickness of the lifting steel plate cannot exceed the specified thickness of the jaws.
vertical plate lifting clampss are strictly prohibited from lifting from above the personnel. During the lifting process, they must not collide with other objects. The lifting person must assist the crane driver to do the reminding work for the personnel in the direction of the object to avoid accidents. No lifting clamps shall be used beyond the rated load.
