Earthmoving machine 220hp mini bulldozer 822D in Kenya
Hydrostatic Drive System
Hydrostatic drive with electronic control technology
- Hydrostatic system delivers higher efficiency and maximumoutput traction force of 280KN. for 816, 350KN for 822.
- Maintenance costs are reduced by 60% when compared tocompetitors with torque converter and transmission design.
- Counter-rotation and power turn feature delivers excellentmaneuverability on job sites
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
Semi-Universal (SU) 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 a world class supplier ensures high reliability and resistance to wear.
- Carrier rollers track rollers and idle rollers areall maintenance free.
- Planetary final drive design delivers increased torque ratio for higher transmission efficiency and lower maintenance cost.
- Durable final drive bearings and multiple wet disc brakes provide reliability, reduce system heat and extend overall life.
Structures
- Machine structures are analyzed using Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) toidentify and protect high stress areas.
- Advanced structure welding technique, relieving weldingstress.
Modular Radiator
- New advanced cooling system designed to meet -43°C to +50°C ambient temperatures capability.
- Modular designed radiator, easy to maintain remove and repair.
- Radiator grill provides better heat dissipation, easy access for maintenance.
Maintenance
- Electronic Control Module (ECM) fault diagnosis system, automatic diagnosis of eight key parameters.
- Monitoring system provides three levels of alarm, toindicate fault diagnosis.
- Hydrostatic system has longer service interval (2000 hrs), reduces maintenance time by 50%.
- Implement valve mounted outside of hydraulic tank provides easy access to check and service.
