Control of daily inspection, maintenance and management system during tower crane operation
The probability of accidents in the operation of the tower hanging is the majority, such as illegal operation, equipment with disease operation, etc.. The risk factors are random and difficult to control. Below, the daily inspection, maintenance, management of the tower during the operation of the system control.
1. Daily inspection, maintenance and other quality control.
The tower crane driver, maintenance electrician and mechanical repairer shall carry out regular inspection before and during operation, focusing on the key parts such as wire ropes, hooks, various transmission parts, braking systems, safety protection devices, bolt connections, and hoists. When the author inspected the equipment at a construction site in the city, a tower crane not far away was turning. The base of the tower made a squeaking sound. He went to see that 3 bolts had been cut and used to stop the tower crane in time. The accident occurred. According to mandatory requirements, tower cranes must have specified safety devices: moment limiters, starting weight limiters, height limiters, stroke limiters, rotary limiters, hook safety devices, wire rope slotting insurance, car breakrope devices,
etc.. These safety devices must ensure that they are sound, sensitive and reliable. If damage is found in use, it should be repaired and replaced in a timely manner. It can not be lifted or arbitrarily adjusted. Nowadays, most tower cranes in the construction market do not have collectives, but instead use rotary limiters. Although some of the tower cranes have rotary limiters, they do not have wiring. The tower crane driver, with his own experience, relies on a few turns to estimate the accident. Similarly, torque limiters, weight limiters also have this situation. Therefore, it is very important to strengthen the daily inspection of the tower crane. It is timely found that the fault can be handled in time to prevent many accidents. During use, maintenance must be carried out according to the product usage instructions, and regular maintenance work such as cleaning, lubrication, tightening and adjustment of the crane must be done.
2. Control of the running process
The use of tower crane management is mainly a human factor. It requires operators to have a high degree of responsibility, understand the mechanical structure and working principles, be familiar with the mechanical principles, maintenance rules, and be familiar with the technical performance of tower crane; The management operator must pass the training of the relevant departments of the country and pass the examination. The quality of relevant personnel such as tower crane operators, cable operators, and command personnel directly affects whether the tower crane can be used safely. It is necessary to strengthen technical training regularly.
3. Control of management systems
We will establish and improve various rules and regulations for the management of Tower lifts, especially the safety operating rules for tower lifts, the permit system for drivers, cable workers, and commanders, the maintenance system for tower lifts, the succession system, and the safety education system. We should follow the rules and regulations of the tower crane management system. We will further strengthen the responsibility system for security and ensure that the various security management rules and regulations are put into practice. For example, if the operation rules of the tower crane machinery are strictly followed during use and the tower crane is "ten forbidden and ten not suspended" for operation, no illegal operations or barbaric operations are allowed, and no illegal command is eliminated.
