① The hooks and rings used in lifting operations must have a smooth surface and must not have defects such as breaks, peelings, scratches, sharp angles, seams, and cracks;
②Hooks and rings must not be used with excessive loads;③The hook should be able to rotate flexibly; the use of repaired hooks and rings is not allowed;④The hook deflection angle should not exceed 10 degrees⑤When using a hook to connect a heavy lifting ring, the position and force of the hook must meet the requirements;⑥The positioning bolts, cotter pins, and nuts above the thrust bearing of the hook are tightly tightened, and the connection is reliable;⑦The lifting ring must bear vertical force when used, and lateral force is strictly prohibited;⑧The thread of the lifting ring must be tightened when rotating to prevent looseness and the hanging object falling off;⑨When using two lifting rings to work at the same time, the angle between the two lifting ring surfaces shall not be greater than 90 degrees.① The hooks and rings used in lifting operations must have a smooth surface and must not have defects such as breaks, peelings, scratches, sharp angles, seams, and cracks;
