Tower crane safety management rules and regulations?

The main construction period of the dumper room of Huanghua Port Phase III Project is about 6 months, during which the workload of tower cranes is heavy and the working hours are long. Three tower cranes were installed in the dumper room according to the engineering requirements, including one QTZ63 (arm length 5 meters) and two QTZ8 (arm length 58 meters). In use, when tower cranes are working at the same time, there is a cross situation. The height difference between tower cranes is 5 meters, 1# tower is 5 meters higher than 3# tower, and 2# tower is 5 meters higher than 1# tower. In the process of work, it is necessary to avoid the cross of the big arms when the front end of the tower crane is hoisted, so as to prevent mechanical accidents. Tower crane driver management system In order to ensure the smooth completion of the third-phase dumper room project and the safe operation of equipment during construction, the tower crane driver management system is formulated as follows: 1. The tower crane driver must abide by the rules and regulations of the project department, ensure the normal operation of equipment and personnel 24 hours a day, and meet the needs of on-site construction. If the tower crane driver asks for leave, he must obtain the consent of full-time management personnel and leaders of the project department before leaving. 2, the driver must install the tower crane safety operation procedures, put an end to unsafe factors. The tower crane driver should know the operating tower crane equipment, check it regularly, maintain the tower crane according to the operation method of "cleaning, lubricating, fastening, adjusting and anticorrosion", and report the bad phenomena of the equipment to the full-time management personnel of the project department in time, so as to eliminate the faults in time and ensure the normal operation of the equipment. 3, each tower crane fixed two tower crane drivers, due to special reasons need to change the tower crane driver, must obey the arrangement of the project department full-time management personnel. 4, without the consent of the project department, the tower crane driver shall not be replaced without authorization; If it is necessary to replace the tower crane driver, it must be approved by the project department, and the replacement of the tower crane driver must be verified by full-time management personnel before taking up the post. 5, tower crane driver at work, must obey the command of full-time bell man, at the same time refused to command requirements of other personnel except full-time bell man, but emergency stop instructions to anyone, shall be executed immediately. During the hoisting process of tower crane, it is forbidden to overload and overload lifting to ensure the safe operation of tower crane. 6, tower crane driver is strictly prohibited to go to work time, noon break to drink. You must concentrate on your work, and it is forbidden to chat and listen to music on your mobile phone at work, so as not to affect your work. 7, in the normal work of tower crane, if you have any other problems, to timely put forward to the project department, the project department as the case may be. 8. Don't hoist: (1) Don't hoist obliquely (2) Don't hoist when overloaded (3) Don't hoist when the bulk material is too full or loosely bound (4) Don't hoist the edge of the hoisted object without protective measures (5) Don't hoist when people are standing on the hoisted object (6) Don't hoist when the command signal is unknown (7) Don't hoist the buried component (8) Don't hoist when the safety device fails (9) Look at it in dark light. Demolition must be carried out in accordance with regulations, and safety operation measures shall be formulated, which shall be carried out by a professional team (group) with demolition qualification under the unified guidance of the team (group) leader, and technical and safety personnel shall be present for supervision. 2. After the tower crane is installed, the verticality deviation value of the tower body shall not exceed 3/1 under no load. 3, tower crane special distribution box, power switch should conform to the specified requirements. 4, tower crane must be installed car walking, luffing, hook height limiter and torque limiter and other safety devices, and ensure sensitive and reliable. 5, tower crane tower, shall not hang placards. 6. Check before operation: (1) Appearance of mechanical structure, and all transmission mechanisms should be normal. (2) The oil level of each gear box and hydraulic oil tank shall meet the standards. (3) The connecting bolts of main parts shall meet the standards. (4) The wear of steel wire rope and the pulley should comply with the regulations. (5) The power supply cable shall be undamaged. 7. Check that the power supply voltage reaches 38V, and its variation range shall not exceed+2 V. Before sending, start the control switch at zero. Turn on the power supply and check that there is no leakage in the metal structure before starting the machine. 8, no-load operation, check the walking, slewing, lifting, luffing and other institutions of brakes, safety limit, protective devices, etc., after confirmed normal, before operation. 9. When manipulating each controller, it should be operated step by step in turn, and it is forbidden to operate beyond the gear. When changing the running direction, the controller should be turned to zero, and then conveyed to the other direction after the motor stops running. Try to operate smoothly, and it is forbidden to start and stop suddenly. 1, hook lifting close to the top of the boom, the car to the end, should slow down to stop position. The hook shall not be less than 1m away from the top of the boom. 11. After lifting heavy objects, it is forbidden to fall freely. When the weight is in place, it can be lowered slowly by micro-motion mechanism or brake. 12. When the lifting weight is translated, it should be more than .5m higher than the obstacle it crosses. 13, three tower crane operations, should keep any close parts between two machines (including lifting heavy objects) distance shall not be less than 5 m.. 21, homework, tower crane boom should be turned to the downwind direction, and loosen the slewing brake. The trolley and counterweight should be moved to the non-working position. Lift the hook 2 ~ 3m away from the top of the boom. 22. Turn each control switch to zero position, disconnect each switch in turn, close the doors and windows of the operation room, and cut off the main switch of power supply after disembarking. Turn on the high-altitude indicator. 23, any personnel on the tower inspection or repair, must wear a seat belt. Daily maintenance system of tower crane In order to further strengthen and control the daily inspection and maintenance of tower crane in the process of safe production, this work should be carried out by the driver before shift every day. There are the following points: 1. Three insurances (i.e. hook insurance, wire rope drum insurance and ladder guard ring) and five limits (i.e. overload limit, amplitude limit, ultra-high limit, walking limit and rotary limit) must be complete and sensitive. 2, it is forbidden to use broken wire super standard wire rope and waste wire rope and surface corrosion of wire rope. Check whether all kinds of rope clamps, slings and ropes are equipped reasonably before and after work. 3. Cab doors and windows are in good condition and effective against rain. 4, with the transmission line distance attached to the provisions, and effective protective measures, all kinds of protective measures should be complete and firm. 5, must abide by the "ten don't hang" and other relevant safety regulations. 6, after the completion of the work, should lift the hook, the car in, all operators in zero. Cut off the power supply, lock the electric box and close the doors and windows. Tower safety operation procedures 1. Pre-operation inspection 1. Hand-over procedures must be carried out at work, and the filling conditions and records of mechanical resume and hand-over records must be checked. 2, check the fastening of the main bolts, weld and protagonist steel without cracks, welding and other phenomena. 3, check the oil level of mechanical transmission gearbox, hydraulic oil tank, etc. meets the standards. 4, check the ministries brake wheel, brake band (shoe) without damage, brake sensitive; Hooks, pulleys, snap rings and wire ropes shall meet the standards; Safety devices (torque limiter, weight limiter, walking, height amplitude limit and hook insurance, etc.) are sensitive and reliable. 5, operating system, electrical system contact is good, no loose, no bare wires, etc. 6, distribution box before sending, linkage controller should be at zero. After closing, check that there is no leakage in the metal structure before starting the machine. 7, all electrical systems must have a good grounding or zero protection. A set of grounding every 2m shall not be connected to the building, and the grounding resistance shall not be greater than 4Ω (Ω). 8, tower crane parts in operation within 1m can not have obstacles. 9, tower crane before operation should be no-load operation or test run, confirmed before put into use.
