For the equipment that is not easy to package, take a big block and lift it after sealing the vehicle to ensure the safety of the lifting process.

3. Ensure that the rated traction of the winch is less than the breaking tension of the wire rope. If there is any cutting or squeezing of the wire rope, it must be replaced by a 4T chain or stirrups.

31. When the winch lifts the hook head, each switch and the car stopper must be guarded to prevent the car stopper and the hook head from being damaged.

32. When pushing a cart at the parking lot and lane change, people should avoid the scope of wire rope to prevent skipping rope from hitting people. When loosening the car, there is no excess rope, and the safety facilities of the parking lot should be restored immediately after the car passes the slope change point.

33. When handling faults in inclined lanes, the driver must brake the brake of the winch tightly, lock the car to the track with a chain or rope sleeve from above, and then handle the faults. Personnel are not allowed to work under the car, and anti-skew measures must be taken when working on both sides of the car to prevent injuries.

34. When disposing of the road car, first check the situation and stability of the car, cover up the car, lay the pillar below, and tighten the winch rope. If there is any problem with the car sealing, it must be reloaded. If there is no problem with the car sealing, the road can be started from below. This work must be commanded and supervised by a special person.

35, transportation shall not exceed two cars at a time.

36. During the operation, the winch driver shall not lift the rope by hand or use the pedal rope, listen to the signal accurately, and shall not leave his post without authorization.

(2) Install car stoppers in each parking lot to prevent vehicles with ropes from entering the non-running parking lot or section by mistake.

(3) Install a car stopper at the entrance of the upper flat yard, which can control the vehicle to enter the place where the hook is disengaged.

(4) At the upper flat car yard near the slope change point, a car stopper is installed to prevent the unconnected vehicles from sliding into the inclined lane.

(5) At the location where the general plan is greater than 1 train length under the slope change point, a barrier is set to prevent the unconnected vehicles from getting off the sports car.

(6) Signal devices that can give out warning signals when cars are dumped are installed in each parking lot.

43. The hoist, chain and rope sleeve used for lifting heavy objects should be carefully checked before use. Unqualified ones are not allowed to be used, and they are not allowed to be overloaded.

44. When lifting, experienced workers should choose the lifting point and check the roof. When lifting, personnel should avoid under the lifting point, under the lifting beam, under the heavy object and the direction of force rebound. The lifting should be commanded by special personnel, and the changes of the roof should be observed at all times. If any abnormal situation is found, the operation should be stopped immediately and handled. When lifting the equipment, the center of gravity of the object should be found and the lifting should be carried out smoothly.

45. The lifting operation shall not be stopped in the middle, and the personnel shall not leave their posts or act without authorization. When it is necessary to stop, the objects must be dropped and stabilized.

46. Check whether the lifting is firm and reliable, otherwise it is not allowed to lift, understand and master the weight center of gravity of the lifted object and the reliability of the lifting point, and select lifting tools and devices that meet the requirements.

47. Before lifting, check the surrounding conditions. No one can stay within 5 meters except the operator.

48. The dismounting part of the sling should be padded with soft materials to prevent sliding and rigging damage.

49. When transporting equipment, pay attention to the liquid inlet and outlet and the joint surface to prevent damage to the equipment.
