1. In tension stringing construction, puller is one indispensable tool of main tools and its performance has direct impact on quality and progress of stringing construction.
2. Important components of the puller, with reasonable design and high safety coefficient, are selected from international famous professional manufacturers such as German Rexroth, German , American Eton, Italian ATOS; other parts and auxiliary equipment are also selected from domestic excellent products, in addition to strict production management by this company, thereby it effectively guarantees fine performance and reliable quality of the product and wins the flavors of numerous customers.

Purposes and characteristic

1. 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.
2. 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.
3. 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.
