With front-to-rear weight distribution optimized for stability in hard cuts, standard electronically controlled all-wheel drive maximizes traction and mobility for the new RM600 and RM800.
Expanding the product line, the new cat The RM600 and RM800 reclamation/stabilizers offer the power, performance and productivity needed to efficiently complete full-depth soil reclamation and stabilization projects.
These versatile machines compete at the top end of the reclaimer/stabilizer size class with an all-new adjustable height design capable of cross-slope cutting, the manufacturer said.
Its powerful turbocharged Cat C18 engine gives the RM600 up to 17 percent more power than the RM500B. The RM800 offers up to 42% more power than the RM500B and up to 23% more than the RM600.
These recuperator/stabilizer models adopt key rotor system components from Cat cold mills for reliable cutting and mixing. With a belt-driven rotor drive system, the machine is capable of cutting flush on the right side.
The new System K rotor utilizes the same base block and double-tapered tool holder components without clamping the cold planer to deliver superior material quality on a variety of projects. The exit and return to cut functions simplify operation, save time and ensure that the machine maintains a constant depth of cut.
Efficient power, high mixing quality
Two configurations are available for the Cat C18 engine to meet regional emissions requirements. Its robust cooling system uses a fresh air intake to maximize fuel efficiency and reduce emissions. To allow the system to cool more efficiently to extend cleaning and maintenance intervals, automatic cooling fans periodically cycle in reverse to clean the heat exchangers.
A single Electronic Control Module (ECM) monitors engine performance and provides diagnostics to the operator.
With front-to-rear weight distribution optimized for stability in hard cuts, standard electronically controlled all-wheel drive maximizes traction and mobility for the new RM600 and RM800. Four height-adjustable legs provide up to + or – 12.5 percent (8 degrees) of slope on either side when working on uneven terrain or to maintain traction in difficult soil stabilization applications.
Two heavy-duty, self-tensioning six-rib belts prevent slippage, while the rotor drive features a heavy-duty hydraulically actuated clutch that requires no adjustment. The high-strength, abrasion-resistant alloys of the System K rotor can withstand tough, high-power applications, and the cutting tools are strategically placed to provide ideal material sizing and homogeneous mixing results.
The versatile rotor can be configured with bolt-on paddle tool support protection for full-depth recovery applications or wedge protection to reduce drag for ground stabilization.
The new models offer the power and performance to efficiently cut 96 inches wide to 20 inches deep. Advanced electronic controls and automatic load control maintain rotor mixing depth and optimum machine speed to deliver ideal mixing quality.
Adjustment of the front and rear mixing chamber doors allows instant modification of material gradation, and an easy-to-read touchscreen indicator informs the operator of door positions. A rear rotor chamber door float feature simplifies operation by allowing the operator to select the desired down pressure. RM600 and RM800 also offer bi-directional cutting capability.
Increased versatility
The positioning of the wheels in the corners provides a highly maneuverable recovery/stabilizer design. The machines can navigate an incredibly small 10.1 feet. inner turning radius. Four steering modes (front only, rear only, crab and coordinated) further improve on-site maneuverability. Offering up to + or – 12.5 percent (8 degrees) of slope on either side when working on uneven terrain or to maintain traction in difficult soil stabilization applications, the four-post design and adjustable height improve stability and cutting precision.
Water and emulsion spray systems are available for the new machines, and the emulsion system features self-cleaning nozzles and is designed to deliver water and bitumen emulsion. Computer metering provides accurate application rates with variable flow rates from 8 to 500 gal/min. for water and 8 to 225 gal/min. for emulsion to meet site needs. The operator controls the flow of additives and customizes the spray width from inside the cab.
Simple and convenient operation
Inspired by the RM400 design, controls are grouped by function for quick and easy access. A small steering wheel provides precise steering, while the operator easily adapts machine speed and functions to grading specification using the large 10-inch color touchscreens and push-button controls.
Sliding hydraulically from side to side, the cab is easily positioned to improve visibility to the front and sides of the machine. Floor-to-ceiling glass and an angled panel on the right-hand side provide a clear view of the work ahead and the leading edge of the cutting chamber.
Fully pressurized cab design with air conditioning and heater/defroster provides a comfortable environment for the operator while keeping out noise, dust and the elements.
Standard and optional cameras enhance the performance and safety of the new RM600 and RM800. Improving front and rear visibility, standard front- and rear-mounted cameras provide configurable guidelines on the touchscreen. Two standard cameras mounted above the front and rear mixing chamber doors give operators visibility into obstructions and material grading. Optional side-mount cameras provide views on each side of the machine.
Reduced maintenance
Long service intervals reduce ownership and running costs from RM600 to RM800. Engine oil service intervals occur every 500 hours of operation. Provided the recommended sampling schedules are followed, hydraulic oil service and coolant change intervals are extended to 6,000 and 12,000 hours respectively. Access to maintenance points is easy with daily checkpoints centrally located on a secure platform.
The standard compressed air system can power pneumatic tools and offers two access points to reduce rotor bit change time. Service mode allows the motor to run while the machine is locked, supplying compressed air so the rotor can be safely repaired. Side service doors provide quick access to inspect or change end ring bits without reaching inside the rotor chamber.
Further simplifying rotor maintenance, the rotor can be hydraulically actuated to rotate in any direction via a control pendant.
The new models feature built-in diagnostics to monitor machine systems, alert the operator to performance issues and simplify troubleshooting. Standard Product Link provides critical machine status, operation and location data and enables the use of Cat Remote Services. Dealers can virtually diagnose machine problems before dispatching a technician using Remote Troubleshoot, helping to ensure the right tools and parts are available to perform repairs. Remote Flash ensures that the machine is running the latest software, updated at a convenient time for the production schedule.
