Introducing Two New Reclaimer/Stabilizer Models by Cat

Cat is set to unveil two brand-new reclaimer/stabilizer models: the RM600 and the RM800, both developed from the ground up.

Mark Eiden, Cat’s Global Sales Consultant, highlights that this introduction expands the brand’s equipment category offerings, providing the widest array of choices for customers.

“This accomplishment is the outcome of extensive validation and attentive listening to our customers,” he stated, estimating that around 10,000 hours of validation efforts have contributed to this achievement.

The primary objectives of the two new machines encompass enhancing performance, ensuring easy maintenance, and providing optimal operator comfort.

Both models are equipped with the reliable Cat C18 engine. The RM600 model features a single turbo and delivers a remarkable 17% increase in power compared to the RM500B. On the other hand, the RM800 model comes with twin turbos, offering an even more impressive 23% increase in power over the RM600.

The cooling system optimizes fuel efficiency by utilizing cool air. Moreover, reversible cooling fans not only improve efficiency but also clean the heat exchangers, leading to extended maintenance intervals. The cutting tools are designed to deliver precise material sizing. For reclamation applications, a bolt-on paddle toolholder can be configured on the rotor, while it can be easily switched out for a wedge when performing soil stabilization tasks.

The operator can easily choose the appropriate down pressure with the help of a hydraulically actuated floating rear rotor chamber door. Moreover, when there is a substantial amount of material in the chamber, the door can be opened to accommodate it effectively.

The automatic load control system ensures that the rotor maintains the desired mixing depth and machine speed, resulting in precise mix quality. The presence of depth indicators on both the side and front legs allows a ground person to guide the leading edge of the rotor effectively. The new models have the capability to cut 2.4 meters wide and 50 centimeters deep.

The focus on operator comfort starts with a newly designed cab featuring easy-to-learn controls integrated with the latest technology. The cab is equipped with heat and air-conditioning for optimal comfort during operation. It also offers enhanced visibility with floor-to-ceiling glass, including an angled pane on the right side that provides a clear view of the cutting chamber’s leading edge. The full left-to-right sliding cab further enhances sightlines, leading to improved productivity and increased safety.

Operators will find great comfort in the heated air-ride suspension seat, which offers 180-degree positioning for optimal support. The standard 25-cm color touchscreen display, conveniently positioned in the headliner, provides easy access to important information. Additionally, an auxiliary display near the armrest offers added convenience. To further enhance visibility, the equipment comes with standard configurable front and rear-mounted cameras, and optional side-mounted cameras are available as well.

The controls are thoughtfully grouped by function, and a mini wheel on the armrest replaces the central steering wheel, ensuring clear sightlines for the operator. Scott Reynolds, CEO of ARS Companies and one of the Cat customers involved in field testing, praised the ergonomic creature comforts, stating that they contribute to enhanced productivity.

Enhanced versatility

Cat has introduced new reclaimer/stabilizers the RM800

Tailored for full-depth reclamation and stabilization projects, both Tier 4 Final machines offer exceptional stability achieved through front-to-rear weight distribution and consistent traction. The machines feature four independent columns that facilitate leveling and enable the chassis to be raised for easy maintenance or cross-slope cutting.

The rotor drive system, powered by a belt, is designed to handle heavier cuts efficiently. The rotors are free from pins, fasteners, or setscrews, simplifying maintenance. Enhanced stability is achieved by adding weight over the rotor area.

The RM600 and RM800 models offer four steering modes (rear-wheel, front-wheel, crab, and coordinated) to enhance maneuverability. With wheels at each corner, these machines can achieve the tightest turning radii. Electronically controlled all-wheel drive further aids in providing excellent traction and mobility.

At the front of the machines, dual hookups are positioned for a spray system to dispense water and bitumen emulsion. According to Eiden, these hookups are exceptionally accurate even at low flow rates. Equipped with self-cleaning nozzles, the spray system is available in both manual and automatic modes, and it can be configured for any mix design, whether it’s based on volume, area, or a percentage of soil density.

Maintenance made easy

With the RM600 and RM800 models, Cat guarantees extended service intervals. One example of this is the auto-reversing cooling fan, which effectively prevents debris build-up, leading to longer maintenance intervals.

For maintenance purposes, the machines offer convenient access points, making the process easier. A walk-in access is provided through an opening hood. Service doors on both sides of the rotor chamber allow for easy inspection or replacement without the need to reach inside the rotor chamber. Additionally, the rotor can be cleaned and bits replaced efficiently with the help of hydraulically powered turning and a control pendant.

Equipped with a standard compressed air system capable of powering pneumatic tools, the machines feature two access points, expediting rotor bit changes. The controls are adjustable, allowing the operator to exit at ground level and elevate the machine for bit service. To ensure safety while the engine is running, a rear safety switch with lock-out functions is included. Additionally, an optional high-pressure wash system is available for efficient and rapid cleanup.

Both machines are equipped with built-in diagnostics to closely monitor performance and offer troubleshooting information, enabling remote diagnosis when necessary. With a rich design history dating back to the late 1950s, Cat has a solid foundation on which these new models are built, as per Eiden’s belief.
