Rotor depth control can be manual or automatic, with electronic over hydraulic control as an option. The steering system includes front and rear wheel steering, with optional crab and coordinated steering modes.
Norms and Recommendations
The machine's frame is made from heavy gauge steel and includes a Roll Over Protective Structure (ROPS) and Falling Object Protective Structure (FOPS) for safety. Optional equipment includes a sliding cab, rear wheel-drive for increased tractive effort, and a water spray system for accurate water addition during processing.
Key Features
- Closed-loop hydrostatic drive for dynamic braking.
- Front wheel drive with optional rear wheel-assist for all-wheel drive.
- Three rotor speeds for various materials and applications.
- Maintenance-free Caterpillar batteries for maximum cranking power.
- Product Link System for equipment tracking and maintenance scheduling.
Operating Dimensions and Weights
The machine's overall length is 1000 mm, width is 3000 mm, and height at ROPS is 3500 mm. The operating weight varies depending on the rotor type, with the universal rotor configuration weighing approximately 24,450 kg.
System Components
The system includes an operator interface panel, a hydraulic filter, an EDC controlled hydraulic pump, a vane-type centrifugal pump with a capacity of 379 - 1895 liters per minute, an in-line flow meter, a spray bar with nozzles, and a hydraulically operated single valve spray bar shut-off.
Powertrain Guard
This feature includes three bolt-on steel guards designed to protect the engine crankcase and hydraulic hoses located at the front axle area.
Rotors
  • Universal Rotor: Designed for asphalt reclamation, featuring breakaway bolt-on tool holders with a maximum cutting depth of 457 mm.
  • Soil Rotor: Intended for soil stabilization, includes weld-on tool holders and offers a maximum cutting depth of 508 mm.
  • Combination Rotor: Primarily used for soil stabilization with secondary applications in light road reclamation cuts, featuring bolt-on tool holders and a maximum cutting depth of 508 mm.
