Cable puller uses requirements and work process

- Jul 06, 2019-

The cable puller is also called a ratchet retractor when it is used, and is used as a tensioning wire in an overhead line installation facility. When using, first loosen the wire rope or galvanized iron wire on the wire tightener, fix it on the cross arm, clamp the wire with the clamp, and then pull the special wrench. Due to the anti-reverse action of the pawl, the wire rope or the galvanized iron wire is gradually wound around the ratchet roller to tighten the wire. Secure the tightened wires to the insulator. Then loosen the pawl to loosen the wire rope or galvanized iron wire, then loosen the wire clamp and wind the wire rope or galvanized iron wire around the roller of the ratchet.


Pay attention to the following points when using the tightener


1. The wire tightener of the corresponding specification should be selected according to the thickness of the wire. The wire rope should be straightened and not twisted during use.


2. The ratchet and pawl should be in good working condition and there should be no tripping. Should be added to the oil when applied



When using the wire tightener, if it is found to be slippery, stop using it immediately, and take appropriate measures (such as winding a layer of wire on the wire) to secure the wire and continue to use it.


The tightener is a tool used to tighten the cable during the construction of the transmission line, adjust the position of the equipment or equipment, replace the insulator and other tensions during the construction process. The double hook tightener is made of steel and aluminum alloy. The former is heavier, but it has a large bearing capacity and can carry a tension of 100kN. The latter is light in weight and easy to carry, but the large load is generally not more than 50kN.
