Power Line Stringing Equipment 150kN Puller Machine For Overhead Line With Cummins Engine
| Purposes and characteristic | |
The machine is a kind of high efficiency electric construction machinery, with good entire performance, high configuration of main functional components, large power reserve, quick pulling speed and wide application. The machine is mainly matched with small efficiency tensioner, is used for the stringing of pulling ropes and also pulls conductor under meeting pulling force. It can satisfy the stringing of double-bundle LGJ-720 and below conductor in mountainous area and foothills, four-bundle LGJ-630 and below conductor in flatlands, OPGW or ADSS optical cable in various terrains, and 500KV and below wire pulling ropes in various terrains. | |
