ENGINE

Equipped with a CAT3306B(L) or Cummins NTA 855 series engine. These engines are purpose-built to produce high torque coupled with superior reliability and performance with energy-saving. An effective cooling system is required to suit different climates. An all-new enlarged radiator is designed for superior heat-dissipation, ensuring that the engine works at an ideal temperature. Unobstructed access to the radiator makes cleaning and servicing hassle-free

HEAVY DUTY STRUCTURE

Adopting a highly reinforced hull frame that is welded together by robots as its core. The frame is then tested by a five-axis measuring device to ensure its quality and fit. This extensive process ensures that all other components fits onto the frame perfectly resulting in a flawless machine.

The oscillating equalizer beam suspension system facilitates the bulldozer to overcome the roughest of terrains resulting in outstanding traction and seamless blade control.

UNDERCARRIAGE

The undercarriage components adopt Italian heat treatment technology, incorporates imported Japanese oil seals and larger bushings to increase the life span on this major wear and tear components for optimum strength and durability, and lower the running costs
