| TY220 Hydraulic Puller |
| The machine allows for the tension stringing of 4-bundle conductor
of 630mm2 and below in mountainous and hilly areas, and of 4-bundle
conductor of 720mm2 and below in flat lands; besides, it can be
used for traction stringing of OPGW or ADSS optical cable and 500kV
traction stringing 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. |
| Configuration |
- Hydraulic dynamometer with set-point and automatic control of
maximum pull
- Hydraulic oil cooling system
- Control instruments for hydraulic system and diesel engine
- On board reel winder with automatic level wind, suitable for
standard reel mod. 1400 and 1600
- Hydraulic front stabilizer
- Grounding connection point
|
| Additional Devices |
- Lighting system for the trailer
- Air brake system for the trailer
- Hydraulic rope clamp for reel change(extra charge)
- Swivel guide rope roller
- Trailer for towing at max speed of 30 km/h
- Extra shaft
- Digital speed and meter counter
