Main configuration

1. Engine: Cummins
2. Main pump: German (Rexroth)
3. Main motor speed reducer: German (Rexroth)
4. Tail bracket hoisting motor: American (Eton)
5. Hydraulic meter: German

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

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.

Additional Devices
Lighting system for the trailer
Hydraulic brake system for the trailer
Extra rollers for an additional pilot rope
Hydraulic rope clamp for reel change operations
Extra shaft
Electronic pull and speed recorder
