Caterpillar Inc. is pleased to announce the availability of the PM620 and PM622 Cold Planers. The machines are high-production, highly maneuverable half-lane milling machine that perform controlled full-depth removal of asphalt and concrete pavements in a single pass.
Operating weight for the PM620 is approximately 33 330 kg (73,260 lb) and the PM622 is approximately 33 900 kg (74,580 lbs). Transport weight for the PM620 is approximately 29 400 kg (64,680 lb), and the PM620 is approximately 30 000 kg (66,140 lb).
Engine
The PM620 and PM622 are powered by a Cat® C18 ACERT™ engine, a turbocharged, 6-cylinder diesel engine that provides 470 kW (630 hp) of gross power. The C18 engine meets regional emission requirements. In regions that require it, the engines meet U.S. EPA Tier 4 Final / EU Stage IV emission standards. For all other regions, the engine meets Tier 3 / Stage IIIA equivalent and China Nonroad Stage III emission standards. The engine is iso-mounted to reduce vibration and increase operator comfort.
Operator’s Environment
The operator’s station features dual operating controls, including joystick steering/propel lever, upper conveyor controls and rear track steering controls. Ergonomic instrumentation layout has been designed for comfort and ease of use. A touchscreen display is visible in day or night conditions, and keypads are backlit for comfortable low light operation. Keypad controls are positioned within easy reach for the operator. A large storage locker is standard. Options that add comfort for the operator include suspension seats and a hydraulically operated canopy. The canopy can quickly deploy and retract to a storage position without disrupting operation. The canopy can be equipped with optional front and rear windscreens that protect the entire width of the operator station.
Cat Grade Control Option
The PM620 and PM622 can be equipped with integrated Cat Grade Control. The 2D-capable/3D-ready grade and slope system automatically controls rotor depth and cross slope to a preset cutting depth, and can be enhanced for full 3D control with the addition of optional equipment. The base system is fully integrated with the machine, providing easier, more precise operation and better system protection. The system can be configured with contacting or non-contacting grade sensors including Cat sonic sensors and mounting hardware, the side plate position or optional inboard ski. The machine can be set up to control grade on both sides using any combination of sensors. Or, the machine can be set up to control grade on one side of the machine and slope on the other. The system allows you to change the sensor arrangement during operation with simple commands, as work site application requires.
