This auxiliary winch, has been designed for jobs in telecommunication network maintenance.
A piston may be connected to the front end of the wire rope (4mm dia.) and be blown by compressed air through ducts of up to 1000m length. The piston may also be used for gauging the cross section of the duct. When the reel is disengaged from the drive, the rope may be freely pulled off, although the reel may at any time be braked by means of the V-belt.
The handy winch maybe used to pulling heavy steel wire ropes of large cable winches or cables of small diameter.
