RM400 Rotary Mixer utilizes sliding cab to improve sight lines and enhance safety

Utilizing both standard and optional cameras, the RM400 hones in on enhanced visibility

RM400 Rotary Mixer utilizes sliding cab to improve sight lines and enhance safety

Replacing the RM300, Caterpillar 's newly announced RM400 Rotary Mixer offers enhanced visibility during operation, four rotor options, and improved maneuverability due to its shorter length.

Available in the second quarter of 2020, the RM400 features a full left to right sliding cab which enhances side-to-side viewing to the tire edges and rotor cut lines for improved efficiency and production. Standard front and rear facing cameras viewed through a display in the cab provide additional visibility, while optional side mounted cameras provide sight lines along the machine for enhanced safety.

Optional cameras can also be mounted in front and behind the rotor chamber. The front camera assists the operator when cutting close to obstacles such as manholes and curbs, while the rear camera provides a good view of the discharge material. Viewing these cameras from the operator's station requires an additional touch screen display.

The machine's hand-wheel steering offers simple control and good forward viewing, while a joystick controls the rear wheels for more precise control. A tablet sized LCD display keeps the operator informed of machine functions, including the front and rear door opening of the rotor chamber.

Four rotor options are available for a variety of applications. A universal rotor can be used for either full depth reclamation or soil stabilization and is equipped with 200 point-attack carbide-tipped tools. A soil rotor is used for a variety of mixing and stabilization applications and blends additives with semi-cohesive or granular materials and is equipped with 238 point-attack, carbide-tipped tools. The combination rotor is designed primarily for use in soil stabilization applications in cohesive materials, but also works well for light asphalt reclamation. The combination rotor is equipped with 114 point-attack, carbide-tipped tools.

Three different rotor speeds help deliver the desired material gradation. An electronic controller keeps the rotor at the proper depth and the machine at a consistent speed to ensure optimal blending performance. The RM400 can be equipped with a water spray system in conjunction with an emulsion system to provide excellent versatility and time savings when additives are needed.

With a 2.4 m (8 ft.) cutting width and an operating length of 9.56 m (31.4 ft.), these features help contractors achieve the demanding job specifications in both full-depth reclamation and soil stabilization applications. The machine weighs in at 23 500 kg (51,809 lb.) and meets U.S. EPA Tier 4 Final and EU Stage V emission standards via the The Cat® C9.3 engine.

Opening New Windows into Remote Asset Management and Worker Safety with Satellite Communications

Industries such as construction, mining, energy, utilities and forestry, face many challenges when it comes to tracking assets and employees. Equipment often has to be transferred between locations, or monitored while it is dormant during off seasons. Lone workers may have to travel long distances or visit multiple sites during the course of their activities. And, all of this is further complicated today with shifting supply chains and economic realities putting further strain on the bottom line.
