High Efficiency Mini Crawler Dozer Heavy Equipment Automatic Speed
Change
The appearance of the Machine is based on optimization design.
◆ High engine power reserve, strong torque output, low fuel
consumption, reliable controls.
◆ The technology of the machine adopted advanced Japanese
technology.
◆ Hydraulically powered, automatic speed change, shift the gears
without stop the vehicle.
◆ 3 elements, single stage and single phase torque convertor
features high efficiency and
capacity.
◆ The updated hexahedral cab features outstanding visibility and
good tightness.
◆ Using the triangle spline and the gear of crowned teeth and tip
relief in the final drive to
average the loads on the trans-mission components for more
stability, prolong the lifetime.
◆ New blade is more durable and capacious.
◆ Alarming & monitoring system is reliable.
◆Implement Controls are Piloted to minimize operating force.
