220hp crawler bulldozer 822D with hydrostatic drive system and joystick

822D specification:

Hydrostatic Drive System
Upgraded hydrostatic system not only leverages Cater-pillar automatic, dual path, hydro-static drive with electronic control technology of the third generation TTT, but also increas-es efficiency and reliability
Adopt Rex-roth German new generation drive pump to combine control valve, trackmotor, simplified hose line design, continue to increase the reliability
Ca-ter-pillar high pressure hose provides reliability and durability. Ca-ter-pillar control technology provides accurate control and high transmission efficiency
Integrated the hydrostatic oil tank and implement hydraulic oil tank to improve filtratedprecision and cooling capability of hydraulic system, increasing reliability and reducingmaintenance 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
