Safety operating instructions for top running crane lifting operations

1. During lifting operations, vrhunska dizalica is necessary to have a comprehensive understanding of the working environment, travel routes, buildings, and object weights at the work site.
2. Operators should sound the signal before carrying out lifting, turning, luffing, walking, hook lifting and other actions, and strictly implement the commander’s signal. Special operators must have a special operation safety operation certificate.

3. Open-air operations should be stopped when encountering strong winds above Level 6 or severe weather such as heavy rain, heavy snow, or heavy fog.
4. Safety protection devices such as the crane’s amplitude indicator, torque limiter, and various travel limit switches must be complete, sensitive and reliable, and must not be adjusted or dismantled at will.
5. Hoisting machinery must operate according to the prescribed lifting performance, and must not be overloaded or lift objects of unknown weight. In special circumstances, when overloading is required, technical measures must be taken to ensure safety. Approved by the technical director of the enterprise, a dedicated person must be appointed. Supervise before lifting.
6. Custom top running bridge crane equipment is strictly prohibited to use a crane to tilt, lift or lift heavy objects buried underground or condensed on the ground. Concrete components or formwork poured on site must be loosened before lifting.
7. When lifting heavy objects, they should be tied steadily and firmly. No scattered objects should be stacked or hung on the heavy objects.

When the wire rope is released, at least three turns should be kept on the drum to prevent the wire rope from looping, kinking, bending and tangling. When using rope clamps to fix the rope, the number must not be Less than 3, the rope clamp sliding saddle should be on the side that receives the force when the wire rope is working, and should not be staggered forward and backward.
