In transmission and distribution industry, the whole set of construction technology, which uses tensioners, pullers and other main equipment to make the conductor with a certain tension in the air, and uses corresponding methods to tighten the wire, hang the wire and install accessories, is called tension stringing . Generally, traction fields and tension fields are set up at both ends of the line-laying section. The main tools include: tensioner that apply tension to the conductor, Stringing blocks that suspend the conductor in the air, puller that pull the conductor, head boards that connect the conductor and the traction rope, and other auxiliary tools. The equipment that applies tension to the tail end of the conductor is called a tensioner, and the equipment that pulls the guide rope is called a puller .

traction force has been set. the traction force pre-adjustment is not enabled, the traction force will not exceed the maximum set value under any circumstances.
automatically adjusted to adapt to the change of the drum diameter, and the tail wire rope can maintain the predetermined tension and brake.
Added to the hoisting mechanism of the puller to effectively protect the tail frame screw and extend the service life of the screw and slider; a manual device is added to the tail rope arrangement, and this function can still achieve neat cable arrangement for traction ropes of special specifications.
When replacing the tail rope reel, there is no need to hold the tail rope by hand. The tail rope hydraulic clamping device is used to make the tail rope replacement safe and reliable. The device is hydraulically controlled and interlocked with the main hydraulic system to prevent misoperation and is safe and reliable.
