Check the brakes, hooks, wire ropes, safety devices and other components according to the requirements of the spot check card. If abnormal phenomena are found, they should be eliminated first. The operator must confirm that there is no one on the platform or track before turning on the main power supply. When the power circuit breaker is locked or there is a notice board, the original person concerned should remove it before turning on the main power... What is the safe operation code of Kunming construction hoist 1. Before working on the Kunming construction hoist, apply the brakes, hooks, wire ropes and Safety devices and other components are checked according to the requirements of the check card, and abnormal phenomena are found, which should be eliminated first. The operator must confirm that there is no one on the platform or track before turning on the main power supply. When the power circuit breaker is locked or there is a notice board, the main power supply can be turned on only after the original person concerned removes it. 2. When lifting heavy objects for the first time in each shift during work (or when the load reaches the maximum weight), the heavy objects should be lowered after the height of 0.5 meters from the ground, check the brake performance, and confirm the reliability. Perform normal operations. During the operation, the operator should ring the bell and alarm for the following operations according to regulations. 3. After working, raise the hook to a certain height, park the cart and trolley at the designated position, and place the controller handle at the 'zero' position; pull down the switch handle of the protective box to cut off the power. Perform daily maintenance. Do a good job of handover. Picture: Kunming 1. When lifting heavy objects, the hook wire rope should be kept vertical, and the object to be hoisted is not allowed to be dragged diagonally. 2. The weight to be hoisted should be located at the center of gravity and tied firmly. The application with sharp angles is good as a mat. 3. Before the heavy object is lifted off the ground, the crane must not make a slewing motion. 4. When lifting or lowering heavy objects, the speed should be uniform and stable to avoid sudden changes in speed, which may cause heavy objects to swing in the air and cause danger. When dropping heavy objects, the speed should not be too fast, so as not to break the heavy objects when landing. 5. When the crane is lifting, try to avoid lifting and lowering the boom. When the boom must be hoisted, the hoisting weight shall not exceed half of the specified weight.
