Electric wire laying of electric eot crane

May 29, 2019
The electric wire of electric eot crane should be laid in the wire trough or metal pipe, if the place which the wire trough or metal pipe is inconvenient to lay or move relative to each other, should use the flexible metal tubing. The wire  or cables can be laid directly, but protective measures should be taken where there is mechanical damage, chemical corrosion, or oil contamination. 

Wires of different mechanisms, different voltage types and voltage levels should be separated as far as possible, and the lighting wires should be laid separately.
 
Electric eot crane single-core wires (or cables) with AC currents above 25A are not allowed to be worn separately.
 
The bending radius of the fixed laying wire or cable shall not be less than 5 times the outer diameter of the cable. The bending radius of the flat moving cable shall not be less than 10 times the thickness of the cable. The bending radius of the circular moving cable shall not be less than 8 times the outer diameter of the cable.
 
Rainproof measures shall be taken for the inlet and outlet,  cable duct and conduit of the outdoor crane wire, driver's cab wire, electric box wire and electrical equipment, and no water shall accumulate in the wire trough.
 
The low-voltage, low-power cables should not use the same cable pipe with power cables or cables of different voltage levels. If necessary, should use shielded cables.
