The corresponding category and working principle of the cable puller
Apr 27, 2018

The cable puller will also be called a tightener, and it will also be called a ratchet tightener. It is used as a tensioning wire when laying overhead lines. In use, the wire rope or galvanized iron wire on the tightener is loosened and fixed on the cross arm. The wire is clamped with a clamp and then the special wrench is pulled. Because of the reversal effect of the pawl, the wire rope or galvanized iron wire is gradually wound on the ratchet drum to tighten the wire.

 

When the cable puller is in use, the tightened wire is fixed to the insulator. Then release the pawl, loosen the wire rope or galvanized wire, and then release the wire clamp. Finally, the wire rope or galvanized wire is wound on the roller of the ratchet wheel.

 

The corresponding categories and working principle of the tightener:

 

The cable puller is divided into a hand pull (hand lever), a ratchet tightener, and a double hook tightener.

 

Hand pullers in the cable puller will also be used mainly for tightening various types of cables such as wires for power and overhead lines, and for pulling and moving equipment and other heavy objects. When the car is being transported, goods such as large equipment are fixed. Hand pull (hand lever) hoist driving method will also have two kinds of hand pull and hand pull, hand chain hoist is to pull through the chain to achieve the purpose of tension, lifting purposes, lever hoist has ring chain lever hoist and Wire rope lever hoist, lever hoist will pull the chain through the handle or the rope to achieve tension, lifting purposes.

 

The ratchet tightener, also known as the ratchet lever hoist, is a tool for tightening and tightening strands of steel strands and small cross-section wires during construction of transmission lines. Usually, the wire is used to fix the wire, and then the wire is tightened to the proper sag through the tightener.

 

The double hook cable puller is a kind of tool used to tighten the pull wire, adjust the position of the equipment or the equipment, replace the insulator and other tools in the construction process during the construction of the transmission line project. Double hook tighteners are available in steel and aluminum alloys. The former is heavier, but allows greater bearing capacity. The largest can carry 100kN tension. The latter is lightweight and easy to carry, but the maximum load is generally not more than 50kN.
