SA-YQZ Hydraulic Puller and Tensioner for OPGW Installation

OPGW Stringing equipments is specially used for exchange old earth wire with new OPGW line. Our puller tensioner with hydraulic tensioner is one set for exchange work. The hydraulic puller Product Directory tensioner has big wheel and strong engine for retrieve the hard earth wire well. It also can drive hydraulic reel stand for retriving the old earth wire on steel or wooden drum.
​The machine is suitable to string various conductor,earthwires,OPGW optic cable compounded earthwire and ADSS self-stand optic cable etc.The bull-wheel grooves are made up of high resistance interchangeable nylon sectors.
