The other is single pole sliding wire.
Seamless sliding wire
The seamless sliding wire doesn’t have joint, which is a whole line, widely used when the crane travelling length is within 100 m crane traveling length.

Application:

when the crane travelling length is within 100m crane traveling length.
Seamless sliding wire is suitable for single girder crane, and just one crane conductor bar is needed for each one crane.
