SEM Good Sale Bulldozer SEM822D Track Type Tractor for Sale
Technical Features
Hydrostatic Drive System
- Upgraded hydrostatic system not only leverages Caterpillar automatic, dual path, hydro-static drive with electronic control technology of the third generation TTT, but also increas-es efficiency and reliability
- Adopt Rexroth German new generation drive pump to combine control valve, trackmotor, simplified hose line design, continue to increase the reliability
- Caterpillar high pressure hose provides reliability and durability. Caterpillar 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
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 efficiency and lower maintenance cost
- Durable final drive bearings and multiple wet discbrakes 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) to identify and protect high stress areas
- Advanced structure welding technique, relieving welding stress
Modular Radiator
- New advanced cooling system designed to meet -40°C to +50°C ambient temperatures capability
- Modular designed radiator, easy to maintain remove and repair
- Radiator grill provides better heatdissipation, easy access or maintenance
Maintenance
- Electronic Control Module (ECM) fault diagnosis system,automatic diagnosis of eight key parameters
- Monitoring system provides three levels of alarm,to indicate 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
