| TY90 Hydraulic Puller |
- This machine allows for the tension stringing of twin-bundle
conductor of 500mm2 and below in mountainous and hilly areas, of
twin-bundle conductor of 630mm2 and below in flat lands, and of
single conductor 720mm2 in various terrains;
|
- besides, it can be used for traction stringing of OPGW or ADSS
optical cable and 220kV haulage rope in various terrains.

Hydraulic Transmission
Closed hydraulic circuit for step less speed variation in both
rotating directions.
This machine is provided with a pull pro-setting system that
maintains the pre-set pulling value (also when the speed is reduced
to "0") by automatically adjusting the operation speed according to
the friction and unexpected loads which may occur.
