Don't hoist: (1) Don't hoist obliquely (2) Don't hoist when it is overloaded (3) Don't hoist when the bulk material is too full or loosely bound (4) Don't hoist when the edge of the hoisted object has no protective measures (5) Don't hoist when there are people on it (6) Don't hoist when the command signal is unclear (7) Don't hoist buried components (8) Jack-up and 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 supervised by technicians and safety personnel. 2. After the tower crane is installed, the verticality deviation of the tower body shall not exceed 3/ 1000 under no-load condition. 3, tower crane special distribution box, power switch should comply with 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 the main components shall meet the standards. (4) Wear of wire rope and pulley shall comply with the regulations. (5) The power cable shall be intact. 7. Check that the power supply voltage reaches 380V, and its variation range does not exceed+20 V. Before sending, set the control switch to zero. Before starting the machine, turn on the power supply and check the metal structure for no leakage. 8, no-load operation, check the walking, slewing, lifting, luffing and other institutions of brakes, safety limit, protective devices, etc. , confirmed to be normal, before operation. 9. When manipulating each controller, it should be operated step by step, and it is forbidden to operate beyond the gear. When changing the running direction, the controller should be set to zero, and then the motor will be transported in the other direction after it stops running. Try to operate smoothly, and it is forbidden to start and stop suddenly. 10, the hook is lifted close to the top of the boom, and when the car runs to the end, it should slow down to the stop position. The distance between the hook and the top of the boom shall not be less than1m. 1 1. Free descent is prohibited after lifting heavy objects. After the weight is in place, it can be lowered slowly by micro-motion mechanism or brake. 12. When lifting heavy objects translate, they should be more than 0.5m higher than the obstacles they cross. 13. When three tower cranes are running, the distance between any close parts (including the lifted weights) between the two cranes shall not be less than 5m. After 2 1. operation, the boom of tower crane should be turned to the downwind direction, and the slewing brake should be released. 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, turn off each switch in turn, close the doors and windows of the operation room, and cut off the main power switch after disembarking. Turn on the altitude indicator. 23, any personnel in the tower inspection or maintenance, 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 risks (i.e. hook insurance, wire rope drum insurance and ladder climbing retainer) and five risks (i.e. overload limit, amplitude limit, superelevation limit, walking limit and rotation limit) must be complete and sensitive. 2, it is strictly prohibited to use broken wire rope, waste wire rope and surface corrosion of wire rope. Check whether all kinds of rope clips, slings and ropes are properly equipped before and after work. 3. Cab doors and windows are in good condition and can effectively prevent rain. 4. The distance from the transmission line shall conform to the regulations, and effective protective measures shall be taken, and all kinds of protective measures shall 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, all operators in zero. Cut off the power supply, lock the electric box and close the doors and windows. Safety operation regulations for iron tower 1. Check 1 before operation. You must go through the handover procedures at work, and you must check the filling and recording of mechanical resume and handover records. 2, check the fastening of the main bolt, weld and protagonist steel without cracks, welding and other phenomena. 3.
