Product Description
Chinese Top Brand 240HP Crawler Bulldozer SEM822D
with Shank Ripper for Sale
Hydrostatic Drive System
- Upgraded hydrostatic system not only leverages Top brand 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.
- Top brand high pressure hose provides reliability and durability. Top brand 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.
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.
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.
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.
