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

• Negative self-acting hydraulic brakes

• Hydraulic dynamometers with set-point and automatic control of maximum pull

• Hydraulic oil cooling system

• Digital meter counters

• Control instruments for hydraulic system and diesel engine

• Rigid axles for towing at max speed of 30km/h with mechanical parking brake

• Hydraulic power pack to control up to 1 drum stand with hydraulic motor or 1 reel winder

• Grounding connection point 

 

Additional Devices

 

• Lighting system for the trailer

• Hydraulic rope/conductor clamp(extra charge)

• Swivel guide rope roller

• Trailer for towing at max speed of 30 km/h

• Digital speed and meter counter
