This TENSIONER is equipment to prevent damage of overhead conductor or OPGW by loosing to ground when stringing work for overhead conductor or OPGW, and also tensile resistant equipment to keep required tensility of the overhead conductor by operating together with engine puller.

Features

Shoe chain increase working ability of the tension by friction minimize of conductor and it's drum

Simple and light maker operating easy

Easy and smooth passing for dead end stocking or stringing clamp.

Valve system ensure to have safety tensility and speed, and also the valve can be locked to stop operating.

Opera table tensility by hydraulic brake is 2,000kgf max. and by using together with hand band brake is 3,500kg max.

Max. running speed of conductor is 60m/min

Oil cooling system helps continuous operating for 10 hours.
