Cat unveils new RM400 Rotary Mixer with extra energy, visibility

Caterpillar plans to launch its new RM400 Rotary Mixer within the second quarter of 2020 to exchange the RM300.

Cat gave the brand new RM400 a 19 p.c increase in energy over the RM300, with a 417-horsepower Tier 4 last Cat C9.3 engine. The brand new rotary mixer was unveiled September 12 at a press occasion at Cat Paving’s headquarters in Minneapolis.

Cat additionally improved the cab, which might slide proper and left for facet views of the tire edges and lower strains. For additional visibility, Cat offers normal entrance and rear cameras and elective side-mounted cameras. Cameras will also be mounted in entrance and behind the rotor chamber. The entrance digital camera helps when reducing near obstacles, comparable to manholes and curbs, whereas the rear digital camera offers a view of the discharge materials. These two cameras will be considered by an extra touchscreen show within the cab.

The 51,809-pound RM400 has a reducing width of eight toes and is designed for full-depth reclamation and soil stabilization. At 41.4 toes lengthy, the RM400 is 17.3 inches shorter than the RM300, offering higher maneuverability in business zones, parking heaps and residential areas whereas additionally bettering visibility, the corporate says. The rotary mixer options normal all-wheel drive with 4 impartial drive pumps for elevated torque, improved traction and higher velocity.

Different options embrace hand-wheel steering for easy management and good ahead viewing, and joystick controls for the rear wheels for extra exact management. A tablet-sized LCD show shows machine features, together with the entrance and rear door opening of the rotor chamber.

Cat provides 4 rotor choices for the RM400:

Common rotor for full-depth reclamation or soil stabilization. It’s geared up with 200 point-attack, carbide-tipped instruments.
Soil rotor for a wide range of mixing and stabilization purposes. It blends components with semicohesive or granular supplies and is supplied with 238 point-attack, carbide-tipped instruments.
Mixture rotor for soil stabilization purposes in cohesive supplies. It additionally works effectively for mild asphalt reclamation, Cat says. It’s geared up with 114 point-attack, carbide-tipped instruments.
Spade rotor for mixing soils. It’s fitted with 58 bolt-on spade instruments.

The RM400 additionally options three rotor speeds for desired materials gradation. An digital controller retains the rotor on the appropriate depth and the machine at a constant velocity for optimum mixing efficiency, Cat says. It may be geared up with a water spray system at the side of an emulsion system for versatility and time financial savings when components are wanted.

Cat additionally made the RM400 simpler to service with an engine hood that tilts ahead when flipping a swap. The cooling system’s variable velocity fan will be reversed for brief intervals to shed mud and preserve the system cleaner. And an elective onboard air compressor, mixed with a tilting rotor hood and enormous rear discharge door, makes it simpler and faster to vary rotor bits.
