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
• Swivel guide rope roller
• Trailer for towing at max speed of 30 km/h
• Extra shaft
• Digital speed and meter counter
