What are the safety requirements of the Overhead Crane Trolley Bus Bar

What are the safety requirements of the Overhead Crane Trolley Bus Bar: (1) design, installation and replacement of Overhead Crane Trolley wire and cable, should be based on the Overhead Crane Trolley's environmental operating temperature, power continuity and other factors, a reasonable choice of current carrying capacity.

(2) The main bus bar of the Overhead Crane Trolley should be powered by a dedicated feeder. For the exchange of 380V power supply, the use of bus bar or cord power supply should be equipped with a dedicated zero line or ground wire.

(3) The main bus bar and control bus bar of the Overhead Crane Trolley, there are two types of pulsed cable or closed bus bar power supply and bare slide friction. In the use of naked slide power supply, the trolley should be straight, smooth and no corrosion. The collector should have sufficient pressure and maintain good electrical conductivity.

(4) Located on the side of the Overhead Crane Trolley cab side of the bare skid should be installed on the screen protection device to prevent the accident when the accident occurred.

(5) outdoor Overhead Crane Trolleys will use pipe wiring, indoor must be used to protect the wiring or pipe wiring. When using pipe wiring, a tube can only wear the same motor wire. Non-corrosive damage to the operating environment can be used to apply insulation wire.

 (6) Overhead Crane Trolley lighting and signal power lines should be connected to the power switch before the power part of the power, it can still maintain normal power supply.

(7) The lighting power supply voltage used when servicing the Overhead Crane Trolley should be a safe voltage.

(8) Overhead Crane Trolley metal structure and all electrical equipment, metal shell, pipe slot, cable metal skin, etc. must be connected into a continuous conductor, according to the grid power supply to take a reliable grounding or zero. Through the wheels and rail grounding (then zero) at both ends of the Overhead Crane Trolley track, should be taken to zero or ground protection. The grounding resistance of the track, and the grounding resistance of any point on the Overhead Crane Trolley shall not be greater than 4 ohms.
