High Quality SEM822D 220HP Hydraulic Crawler Bulldozer with 3 Rippers EXW Price
Advantages and highlights:
1. Hydrostatic Drive System
* Upgraded hydrostatic system not only leverages automatic, dual path, hydrostatic drive with electronic control technology of the third generation TTT, but also increases efficiency and reliability.
* Adopt Rexroth German new generation one case drive pump to combine control valve, track motor, simplified hose line design, continue to increase the reliability.
* High pressure hose provides reliability and durability. Control technology provides accurate control and high transmission efficiency.
* Integrated the hydrostatic oil tank and implement hydraulic oil tank to improve filtrated precision and cooling capability of hydraulic system, increasing reliability and reducing maintenance cost.
* Maintenance costs are reduced by 60% when compared competitors with torque converter and transmission and rear axle.
* Counter rotation, power turn and infinitely variable speed save lots of time,increasing working efficiency.
2. Comfortable Operation
* Counter rotation-Tracks counter rotate to provide best in class maneuverability.
* Powered turn-Machine maintains full power through turns to increase productivity.
* Cruise control - Operators can retain previous speed settings which makes operation easily.
* Multi-function joystick allows for counter-rotation, powered turn and cruise control.
* Pilot joystick control provides comfortable precise blade operation.
3. Semi-Universal Blade
* SU blade combines the excellent penetration of the S blade and the high production capacity of the U blade.
* Designed for superior load retention and penetration in tightly packed materials.
* L-shaped push arms bring the blade closer to the machine, providing excellent maneuverability, balance and blade penetration.
* Blades feature a strong box section design, made from high tensile strength steel to stand up to the most severe applications.
4. Undercarriage
* Undercarriage is provided by China industry expert ensures high reliability and resistance to wear.
* Carrier rollers track rollers and idle rollers are all maintenance free.
* Planetary final drive design delivers increased torque ratio for higher transmission effi ciency and lower maintenance cost.
* Durable final drive bearings and multiple wet disc brakes provide reliability, reduce system heat and extend overall life.
