Operator’s Station

Ergonomic design emphasizes comfort, visibility and easy operation. Isolated operator’s station with heavy-duty rubber mounts reduce machine vibration

ransmitted to the operator. The hydraulically assisted platform slides side-to-side to

t an infinite number of positions. A switch on the side console allows the operator to select any desired position for good visibility and comfort.

The fully adjustable steering column and rotating seat are positioned to provide an optimal operating position. Machine controls are grouped and conveniently located to enhance operator productivity and reduce fatigue.

Performance and reliability you expect.

The RM-500 combines superior performance and reliability to achieve the most demanding job specifications while maximizing machine uptime. With many enhanced features and options, the RM-500 is designed to work well in both full depth reclamation and soil stabilization applications.

Cab

The optional cab increases machine utilization, provides greater year-round

omfort and offers reduced interior

c sound levels. The pressurized cab slides side-to-side and includes a rotating cloth seat, left and right side doors, tinted windows, front and rear windshield wipers, heater/defroster and air conditioning. Sound absorbing floor mat reduces sound and machine vibration transmitted to the operator.

Dual Propel Pumps

The dual pump propel system provides separate balanced hydraulic flow to

oth the rear drive motors and the front

b drive motors to propel the machine with full-time all-wheel drive. This system enables the operator to achieve superior tractive effort for soil stabilization applications that require maximum cutting depth and that are also high in moisture content.

Rotor Drive

A Caterpillar®powershift transmission drives the rotor and provides three rotor

peeds for maximum performance in a

s variety of materials and cutting depths. Heavy-duty shear disc or optional torque limiter protects rotor drive components from torsional stress and shock loads.

Mixing Chamber

Mixing chamber allows the rotor to move independently so that the capacity of the chamber actually increases in deeper cuts to allow better material mixing and excellent gradation. Machine weight is well distributed to provide stability in the cut for uniform depth control.

Rotor Options

With a choice of three rotor options, the RM-500 can be configured for different applications and depth specifications. The universal rotor is intended primarily to pulverize asphalt layers. The soil rotor is intended primarily for soil stabilization. The combination rotor is intended primarily for use in soil stabilization with secondary application in light cuts of asphalt reclamation.

Serviceability

The one-piece fiberglass hood tilts forward for exceptional access to the engine and cooling system. Daily service points are accessible from ground level and are grouped on one side of the engine. Hinged ground level side panels allow total engine access. Hinged service doors open wide for access to power train and rotor drive components. The rotor hood tilts forward to allow access to the rotor and cutting tools. Ground level side access doors on the rotor hood provide convenient access for easy cutting tool removal and replacement.

C15 Engine with ACERT™ Technology

A combination of innovations working at the point of combustion, ACERT Technology optimizes engine performance while meeting U.S. EPA Tier 3 and European EU Stage IIIa emission regulations for off-road applications.

Turbocharged and Air-to-Air Aftercooling (ATAAC)

The turbocharged air-to-air aftercooling system provides high horsepower with increased response time while keeping exhaust temperatures low for long hours of continuous operation.

Air-to-Air Aftercooling

Air-to-air aftercooling keeps air intake

Cat®C15 Engine with ACERT Technology

The C15 engine provides a full-rated gross power (SAE J1995) of 403 kW (540 hp) at 2000 rpm with a torque of 2356 Nm (1738 lb/ft). The combination of large displacement and high torque allow the RM-500 to propel through the toughest materials.

Mechanically Actuated Electronically Controlled Unit Injection (MEUI)

The MEUI fuel system is a unique system that combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. The MEUI system excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C15 to have complete control over injection timing, duration and pressure.

Multiple Injection Fuel Delivery

Multiple injection fuel delivery involves a high degree of precision. Precisely shaping the combustion cycle lowers combustion chamber temperatures, which generates fewer emissions and optimizes fuel combustion, translating into more work output for your fuel cost.

C15 Cylinder Block

The cylinder block is a one-piece, grey iron block that features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. This new design supports the engine’s higher compression ratios and increases its power density. The incorporation of straight-thread, o-ring connection points reduces the loss of engine oil and fluids.

High Cylinder Pressures

High cylinder pressures combined with tightly controlled tolerances promote extremely efficient fuel burn, less blow by and lower emissions.

Service, Maintenance and Repair

Easier service, maintenance and repair is accomplished by monitoring key functions and logging critical indicators. Advanced electronic diagnostic capabilities are possible using Cat Electronic Technician.

temperatures down and in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. New turbocharger, unique cross-flow head, single, front driven, overhead cam and a more efficient intake manifold generate significant improvements in air flow. This generates significant improvements in efficiency and reduced emissions.

ADEM™ A4 electr

The ADEM A4 electronic control module manages fuel delivery, valve timing and airflow to get the most performance per gallon (liter) of fuel used. The control module provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It keeps track of engine and machine conditions while keeping the engine operating at peak
