　　There is no need for cracks and damage to the steel plate clamp, and there is no crack in the ring screw and hole shaft. The steel plate pliers should be dragged easily; The steel plate pliers should be manufactured by free forging or die forging; The steel plate pliers can select two appropriate parts at the clamp interface to copy the mark that is not easy to damage, and measure the mark spacing as the basis for testing the deformation in application.

　　If one of the following conditions occurs, it should be deactivated, repaired or scrapped:

　　Jaw opening exceeds the original specification by 10%; When the damage to the pin and shaft exceeds 10% of the original straight warp, and the damage to the ring screw exceeds 10% of the original straight warp; The surface is cracked; The damage to the clamp body exceeds the original specification by 10%.

　　Q&A:

　　1, suspension training installation and hanging work must be carried out by suspension training installation and hanging work qualifications;

　　The use of tongs suitable for the main purpose; Application within the allowable load range, not overweight;

　　2, in the allowed plate thickness range of application;

　　Do not enter the lifting scope or rotating area; Do not knock or impact lifting and lifting tools;

　　3. The lifting shall not be moved or terminated significantly;

　　To prevent the occurrence of lifting emphasis, in order to ensure good safety, it is necessary to use about 2 lifting pliers; Before application, check the bite head, sealing gasket, obstruction between teeth, damage and its abnormal condition, check and then apply.
