HD32 Hydraulic Crawler Bulldozer

Engine Model: Cummins NT855-C360S10
Rated Power: 257 Kw/1800rpm
Operating Weight: 37.20 tons

Main Features

A CUMMINS NTA855-C360S10 engine gives you more power and reliability you need. With exhaust turbocharger, it can still work normally at altitude of 4,300 meters.

The highly reliable power shift transmission, stable torque converter and the two-stage straight-tooth structure’s final drive transmit power efficiently.

With independent engine cooling water tank, chassis oil cooler, water and air intercooler provides excellent cooling performance and simple maintenance operation to ensure continuous operation of the machine.

The final drive is driven low and provides more powerful driving force and efficient grade ability. The standard straight tilt blade features powerful cutting force and the heavy single-shank ripper can be equipped for the ripping of clay and frozen earth, featuring high working efficiency and super-strong penetrating force.
