Caterpillar introduces PM620 and PM622 cold planers

The Cat® PM620 and PM622 profilers are high-production, highly maneuverable half-lane milling machines that perform controlled full-depth removal of asphalt and concrete pavements in a single pass.The Cat® PM620 and PM622 Profilers are high-production, highly manoeuverable half-lane milling machines that perform controlled full-depth removal of asphalt and concrete pavements in a single pass. The PM620 is equipped with a 2010 mm (79″) wide high production rotor and the PM622 is equipped with a 2235 mm (88″) wide high production rotor. The maximum cutting depth is 330 mm (13″).

A Cat C18 ACERT engine provides 470 kW (630 hp) of gross power and meets regional emission requirements. Automatic Engine Speed Control optimises output to match the load, reducing excessive fuel consumption and wear.

A four-post design with four mode steering and auto-leveling provides smooth operation. A robust propel system provides exceptional traction. True-tracking alignment offers greater steering precision and reduces track pad wear.

The operator’s station features high visibility and dual operating controls designed for comfort and ease of use. An available hydraulically operated canopy quickly deploys and stows without disrupting operation.

Three cutting speeds match the best rotor rpm and torque with the job site conditions. Automatic Load Control continually evaluates engine rpm and controls propel speed as required to maintain peak performance.

Optional Cat Diamond Bits offer the ultimate in cutting performance.

Optional integrated Cat Grade Control, a 2D-capable/3D-ready grade and slope system, provides the machines with additional functions such as automatic plunge cut, ramp-in, ramp-out capability, and a jump-hold feature.

A water spray system lubricates the conveyor belt and helps control dust. The 3400 L (898 gal) water tank can be filled from several different standard and optional ports.

The folding front loading conveyor features height adjustment for raise and lower and a 60 degree swing to the left and right of center.

The machines are designed for easy service. Excellent access to critical systems and maintenance points, a computerised monitoring system and available Product Link help ensure service is quick and timely.
