The brand of the parts may change depending on the factory's spare parts availability. We guarantees that it will use parts of similar quality, and the actual usage parameters will not change.

Engine

• Diesel: 298kw(400hp)
• Cooling system: water
• Electrical system: 24V

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 15 km/h
• Extra shaft
• Electronic meter (extra charge)
