CAT Command for Compaction helps contractors achieve compaction quality
Caterpillar announces the release of Cat Command for Compaction (header image), an operator-assisted technology that automates the soil compaction process and helps contractors achieve compaction quality. The Command for Compaction system is available for use on select Cat vibratory soil compactors.
Simple Set-up and Operation
An in-cab display with an intuitive, touchscreen interface makes setup easy and the system connects to common base stations with no back office or design needed. The operator uses the machine to map the boundaries of the area to be compacted and enters the compaction parameters. Once the operator places the machine in “auto,” the system will control the propulsion, steering and vibration of the machine. Recent jobs are saved in the system and can be accessed through the touchscreen interface.
An integrated object detection system alerts the operator if an object is in the pathway. If there is an area that cannot be compacted using vibration, the operator can choose to turn the vibration system off and give control back to the system once the area has been passed.
By automating the compaction process, operator skill gaps are minimized by providing consistent results based on operator inputs. Command for Compaction enables compaction quality by maintaining constant speed and correct pass count with consistent and precise overlap, allowing contractors to hit compaction targets more frequently.
Caterpillar introduces the RM400 rotary mixer

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 utilizing 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.
Superior Mix Quality
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.
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. A spade rotor is also available.
Daily service points are grouped and easily accessible. The engine hood easily tilts forward with the flip of a switch for easy access to the cooling system and engine. The cooling system utilizes a variable speed fan that can be set to periodically reverse direction for short intervals during operation. This unique design helps the system shed accumulated dust and keep the system cleaner for maximum efficiency and extended service intervals.
An optional onboard air compressor combined with the tilting rotor hood and large, rear discharge door makes changing rotor bits quick and easy.
