TY180 Hydraulic Puller Machine With Cummins Engine For Overhead
Line
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 220KV double-bundle LGJ-630 and below
conductor in mountainous area and foothills, 220KV double-bundle
LGJ-720 and below conductor in flatlands, OPGW or AESS optical
cable in various terrains and single conductor LGJ-720 and below in
mountainous area and foothills, and 500KV and below wire pulling
ropes in various terrains.
