1) The crane driver in heavy lifting or fall, should ensure a smooth, accurate, safe and reasonable operating the device, the anti-hanging objects swing tour, causing objects to fall lifting injuries occur. 2) When lifting operation, it was prohibited in the wagon lifting operations, to prevent re-launched injuries. 18) When lifting operations, large-tonnage cranes, is prohibited on someone or lifting objects float glove lifting large tonnage crane rental, to prevent personal injury accident. 3) crane carrying full load or near full load lifting, large-tonnage crane rental, prohibit simultaneous operation of two or more actions to prevent the lifting was swinging fall, lifting injuries occur. 4) crane operations, the work area should be closed, in case of foreign personnel and vehicles need to enter the job should be suspended. To prevent the occurrence of lifting injuries. 5) When the object is in a suspended state, the cab drivers are not allowed to leave without permission, and only after heavy landing before leaving, to prevent the crane out of control, causing personal injury or damage to the goods. Rope pulley rope kept by slots and reel, to regularly check the wire rope. For non-twist rope, because the special structure, when wrapped around must not destroy or interfere with the original fixed pitch between the strands to prevent slippage or outer cord loose strands forming the cage shape. Wire rope lifting mechanism is an important part, under conditions to ensure manufacturing quality, using factors have a great impact on the life of wire rope. Otherwise, large-tonnage crane manufacturers, wire rope reel winding process will diverge, thereby reducing the service life of the rope. Pulley shown in Figure 1, when the rope around pulley group, the rope being repeatedly reversed bending, bending stress also changes direction, this alternating stress, the affirmation of life reduced rope, therefore, pulley block use, best to use the rope in the same direction as shown in FIG. 3 bent pulley.
