1. We manufacture a lot of models Cable pulling block for different uses in the overhead transmission line construction.
2. They have are used to support conductors, OPGW,ADSS, communication lines.
3.The sheave of the pulley blocks are made from high strength MC nylon,or aluminum materials, and the frame of blocks are made of galvanized steel.
4.Cable pulley block are high strength and flexibility, easy to use, light weight, wearresisting, and long service life.

Power and communication cables are often laid in open trenches where the road and ground conditions result in the cable route having a number of curves. With the cable’s own weight and the high tensions involved the cable cannot be fed cleanly.The ground cable rollers and corner cable rollers are made of aluminium, steel. The sturdy and robust steel frames are completely galvanized and guarantee a long working life even under extreme conditions.
