Update Date: 2015/12/7 comes from: jyrcpr.cn Author: clicks:

1. Design, installation and replacement Xugong truck crane Wire and cable should be selected rationally according to factors such as environmental working temperature and protection rate.

2. Xugong truck crane The main slide line should be supplied by a dedicated feeder. For the AC 380V power supply, a special zero line or grounding wire should be provided when the slide line or the flexible line is supplied. The main line should be painted red paint on the non conductive contact surface and the safety sign or indicator light should be installed in the appropriate position.

3. Xugong truck crane The main slip line and control slip line have two ways: power supply by trochlear dragging cable or closed sliding line and centralized power supply by naked sliding line. When adopting naked sliding mode power supply, the pulley should be straight, smooth and non corrosive. The collector should have enough pressure and maintain good electrical conductivity.

4, located in Xugong truck crane A screen protection device should be installed on the bare line on the side of the driver's cab to prevent electric shock accidents on and off the train.

5, outdoor Xugong truck crane It is necessary to adopt pipe wiring. Indoor protective wiring or wiring should be used. When the pipe is used for wiring, only one conductor in the same pipe can be worn. No corrosive damage can be carried out in the working environment.

6. Xugong truck crane When the bare slide line is used, it should maintain a certain safety distance from the ground or other facilities, such as the ground is not less than 3.5m, the automobile passageway is not less than 6m, the general pipeline is not less than 1m, the oxygen pipeline is not less than 1.5m, and the gas and acetylene gas pipeline is not less than 30m.

7. Xugong truck crane The lighting and signal power lines should be connected before the power switch, and when the power part is cut off, it can still maintain normal power supply.

8, overhaul Xugong truck crane The lighting supply voltage should be a safety voltage.

9. Xugong truck crane Metal structure and all electrical equipment metal shell, tube slot, cable metal outer skin and so on must be connected into continuous conductors. According to the power supply mode of the power grid, reliable grounding or zero connection is adopted. The ends of the truck mounted rails must be connected to the ground by the wheels and tracks. Greater than 4 ohms.
