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 even 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 50% of the specified weight.
6. When the crane is slewing under heavy lifting, pay close attention to whether there are obstacles around it. If there are obstacles, try to avoid or remove them.
7. No people should stay under the crane boom, and try to avoid people passing through.
8. If two cranes are operating on the same track, the distance between the two cranes should be greater than 3m.
9. When two cranes are combined to lift an object, the lifting weight shall not exceed 75% of the total lifting weight of the two cranes, and the traveling and lifting actions of the two cranes must be consistent.
10. Lifting and luffing steel wire ropes need to be inspected once a week, and records should be made. The specific requirements shall be implemented in accordance with the relevant regulations of lifting steel wire ropes.
11. When moving or turning with an empty vehicle, the hook should be at least 2m away from the ground.
12. When the wind exceeds level XNUMX, work should be stopped immediately. TMK should turn the boom to the downwind direction and lower it appropriately, and hang the hook firmly.For gantry cranes, iron wedges (track stoppers) must be pierced and the hooks raised to the upper limit.At the same time, close the doors and windows, cut off the power, and pull the cable wind rope.You should do the same after you finish your work.
