7 Grooves Hydraulic Puller Tensioner Overhead Line Stringing Equipment
275KV transmission line stringing equipments are used for two conductors overhead transmission line stringing operation. We normally used 9 ton hydraulic puller SA-YQ90D with 7 ton hydraulic tensioner SA-YZ2X35 for the double conductors stringing. 8 ton hydraulic tensioner SA-YZ2X40 can be also used.

Application:
The hydraulic puller is used to pull four bundled conductors or 2 bundled conductors for power line construction. It is fully hydraulic controlled, easily used and maintained
Features:
- Closed hydraulic circuit,infinitely variable speed control in both rotating directions.
- The max pulling force for stringing operation can be preset, pulling force in the rope can be read on the line pull gauge.
- Automatic over pulling protection system
- Spring applied hydraulic released brake acts automatically in case of hydraulic failure to ensure safety.
- Hydraulic oil cooling system.
- Heat treated wear-proof bull wheels
- With rigid axle for towing at high speed, the machine looks beautiful.
- Hydraulic actuated pulling rope clamp for convenient reel change.
- Integral self-loading reel winder with automatic level wind.
