10, the bridge erecting machine shall be commanded and operated by designated personnel. During operation, it is forbidden for non-working personnel to get on the bridge erecting machine, and the driver is on duty. It is forbidden for other personnel to enter the bridge erecting machine control room. Strictly prevent the loss of electrical equipment and other components of bridge erecting machine.

1 1. Non-operators are forbidden to enter the girder erection site.

12. It is forbidden for pedestrians and vehicles to pass under the bridge erecting machine when erecting beams.

13. All staff members must wear safety belts and safety helmets when working on docks and abutments. Do not drink alcohol during working hours and get enough sleep. Operators should use safe voltage working lights.

14, stop girder erection when the wind exceeds level 6. It is forbidden to erect beams in rainy days.

15, the power switch should be locked, and a special person should be appointed to open and close the switch.

16. Vehicles parked on the sidewalk must be equipped with non-slip iron shoes and must not be parked without electricity.

17, temporary switches shall be kept and maintained by special personnel. And be familiar with the operation essentials of manual braking of switches, and strictly implement the safety guarantee measures for the use of temporary switches.

19, mechanical operators and beam lifting personnel should receive safety training and hold relevant certificates.

20, before entering the scene of the settled machine, it is forbidden to settle all parts and equipment abnormal situation and problems, not in accordance with the provisions, before the safety preview, shall not be carried out for the next step.

2 1. Protective personnel should be set on both sides of the road section where the bridge erecting machine passes after assembly, and the personnel should avoid a safe distance. When the place where the bridge erecting machine stops may be hit by a slipping vehicle, a derailer should be installed at an appropriate position; Or put the switch in front where other vehicles can't reach the bridge erecting machine, and lock or nail it firmly; If necessary, protective personnel can be set up for monitoring.
