Key Features
Reengine NT855-C280S10, powerful power, energy efficient. Highly reliable power shift transmission, stable hydraulic torque converter, two straight tooth structure of the final transmission, can be efficient transmission of power, with high transmission power and efficient production efficiency. The engine can work normally and reliably under any load conditions and any thermal environment required by the user, without causing the engine to overheat.
It can realize automatic fault diagnosis and whole-process monitoring. Integral cast instrument panel, air conditioning, electrical appliances, instruments as a whole, more beautiful high-grade. The main frame of the whole box structure, the application of high-performance materials and high-strength castings, with high impact load bearing and bending and torsional resistance, high-quality weld to ensure that the main frame has a full life cycle. The semi-rigid suspension walking system increases the ground area of the track and improves the traction force of the vehicle.
According to ergonomics, the driving seat and armrest can be easily adjusted up and down, the transmission, steering and throttle control is placed on the left side, and the flexible shaft structure is used, the working device control is placed on the right side, and the servo control system is used to make the operation process more light and flexible and reduce fatigue.
Applications
SD22 it is mainly applicable to the pushing, excavation, backfilling of earth and stone and other bulk materials on the ground of roads, railways, airports, etc. It is an indispensable mechanical equipment for national defense projects, urban and rural roads and other construction and water conservancy construction.
