What are the basic points for safe crane operation?
Prepare well for homework. All preparations must be made before lifting operations to prevent accidents and accidents. The contents of operation preparation are as follows: 1) Prepare and inspect lifting equipment, including wire rope, shackles, clamps, hanging baskets, etc. 2) Prepare auxiliary equipment, including skids, pry bars, wire hooks, etc. 3) Determine and clear the location of the falling objects, which should be flat and spacious.
Improve bundling technology. The main points are: 1) Before binding components or equipment, appropriate binding points should be determined according to the shape and the position of the center of gravity; 2) When binding heavy objects, consider that there is a certain angle between the wire rope and the horizontal plane when lifting. 3) When bundling objects with edges and corners, they should be covered with wooden boards, tires, sacks, etc. to prevent damage to the wire rope. 4) It is necessary to consider whether the lifting of the heavy objects is convenient for binding. Will the slings be crushed or broken after the heavy objects are put into place? 5) When lifting various loose parts, appropriate fixtures must be adopted to ensure the lifting Shipment is smooth.
Standardization of contact signals. The contact signal is the bridge between the driver and the crane industry. Many accidents are caused by the mistake of information exchange. Therefore, whether it is a ground command signal or a crane warning signal, it should be communicated according to the prescribed standards. Especially the crane driver can only operate after confirming the command signal, hanging state, running channel and landing space. Choose a safe location. In the process of crane lifting, the area endangered by the impact, sway, and fall of the hanging objects is called the danger zone (dead corner). During operation, the lifting industry is often in the danger zone. Therefore, selecting a safe location according to the characteristics of the danger zone under specific conditions is an important aspect of effective prevention of lifting injuries.
