The new Caterpillar RM400 Rotary Mixer delivers a 2.4m cutting width and weighs in at about 23 500kg. The RM400 replaces the RM300 Rotary Mixer and according to a statement by Caterpillar has 19% more power and better manoeuvrability than its predecessor.

The Cat C9.3 engine provides 311kW of power and meets US EPA Tier 4 Final and EU Stage V emission standards. Standard all-wheel drive utilises four independent drive pumps for maximum torque while providing excellent traction and greater speed for moving around the job site. An operating length of 9.56m is 44cm shorter than the RM300. The shorter length improves manoeuvrability in commercial zones, parking lots, and residential areas, while also enhancing visibility.

Furthermore, a full left to right sliding cab enhances side-to-side viewing to the tire edges and rotor cut lines for improved operator efficiency and increased production. Standard front and rear facing cameras viewed through a display in the cab provide good visibility, while optional side mounted cameras provide good sight lines along the machine for enhanced safety.

Additionally, optional cameras can 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.

Hand-wheel steering offers simple control and good forward viewing, while a joystick controls the rear wheels when utilising select modes 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.
