7 Grooves Hydraulic Puller Tensioner Overhead Line Stringing Equipment

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.

1. SA-YQ90D Hydraulic Puller

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.

Main Components:

- Engine: Cummins water-cooled diesel engine.

- Main variable displacement hydraulic pump and main motor: Rexroth (German)

- Reducer: Rexroth. (Germany)

- Reel winder motor: Danfoss (Danish)

- Main hydraulic valves: Rexroth (Germany

- Hydraulic instruments: (German)

- Radiator: AKG (German)

7 Ton Hydraulic Tensioner SA-YZ2X35 for 2 bundled conductors

Application:

It is suitable to string two bundled conductors or single conductor in overhead transmission line.

Features:

- Closed hydraulic circuit, infinitely variable tension force control in both directions.

- The max. tension/pull back force for conductor stringing operation can be presetted, the tension /pull back force can be read from the tension gauge of machine.

- Spring applied hydraulic released brake acts automatically in case of hydraulic failure to ensure line safety

- Hydraulic oil cooling system

- Bull wheels lined with wear proof MC nylon lining segments

- With 2 hydraulic power outlets to control 2 sets of hydraulic reel stands.
