① For newly installed, overhauled or changed hoisting machinery with important performance, hoisting test must be carried out according to relevant provisions of crane performance test before use.

② Before each shift of crane operation, no-load lifting, rotating, luffing, front and rear left and right operation, as well as safety performance test of brake and limit device shall be carried out first. If there is any fault in the equipment, it shall be eliminated before formal operation.

③ The crane driver shall contact the signalman according to various specified gestures or signals. During operation, the driver shall closely cooperate with the signalman and obey the command of the signalman. However, in case of danger in lifting operation, no matter who sends the emergency stop signal, the driver shall stop immediately.

④ After receiving the lifting signal sent by the signalman, the driver must sound the signal before lifting. When lifting, the heavy object shall be lifted off the ground first, and the lifting shall be continued after confirming that the heavy object is firmly hung, the braking performance is good and the crane is stable.

⑤ When lifting a heavy object, the hook wire rope should be kept vertical, and it is forbidden to drag the lifted object when the hook wire rope is inclined. When the hook has been hung but the lifted load has not been lifted, the crane is prohibited from moving or rotating. It is forbidden to lift or pull objects buried or condensed underground or with unknown weight.

⑥ When lifting and rotating heavy objects, the speed should be even and stable to avoid danger of heavy objects swinging in the air. When putting down heavy objects, the speed should not be too fast to prevent them from being damaged by sudden falling. When lifting long and large loads, special personnel shall be assigned to pull the sliding rope. Prevent accidents caused by heavy objects swinging.

⑦ When the crane is lifting a heavy object at a high place, a certain distance shall be kept between the hook and the pulley to prevent the winch from breaking the steel wire rope or turning back the boom. When the boom reaches the elevation angle and the hook is in the horizontal position, the wire rope on the drum shall be kept at least 3 turns.
