SD20-5LNG bulldozer, the world's first bulldozer powered by liquefied natural gas, once again embodies Shantui's world-class level in the manufacturing technologies of bulldozer.
Technical Features
It's equipped with Weichai WP12G220E33NG engine with power output at 200ps to realize low carbon emission and high environmental-friendliness by reducing the harmful gas emission by >90% and effectively prolong the service life of engine due to sufficient combustion of LNG without carbon deposit, featuring low operating cost and significant comprehensive benefits.
The rear four-point shock-absorbing installation is adopted for the gas system. The multi-layer insulated high vacuum tank body features high safety, with the capacity at 500L and the maximum filling capacity at 196KG, which is enough for 12h continuous working.
The installed temperature controlled system features excellent energy-saving and consumption reduction and high economy and environmental-friendliness.
The independently developed control program implements real-time monitoring on the engine and temperature controlled fan.
The bogie adopts central hinge type suspension installation, without splayed beam, to reduce the impact on the drive system.
The drive system adopts modular design and double shock-absorbing installation to ease the maintenances and improve the reliability and comfort of the whole machine.
The high pressure low flow hydraulic system is adopted to reduce the volume of hydraulic units and achieve compact and reasonable structural layout.
The externally installed operating valves ensure easier checking and maintenances.
The hydraulic pilot control is adopted for the working device.
The mechanical operations by single joystick are adopted for the gearshift and the steering.
It features comfortable, labor-saving, accurate, flexible operations, rapid response, and improved efficiency.
The structure of high strength special-shaped tubes, labyrinth seals, and four-point shock-absorbing installation feature low noise and vibration and high comfort and safety.
SD20-5LNG is equipped with standard straight tilting blade and optional U-blade to provide operation possibility for the regions of higher environmental-friendly requirements.
