High Efficiency 220HP Crawler Bulldozer SEM822D Heavy Duty Bulldozer for Sale 

Product Description

Hydrostatic Drive System

• Upgraded hydrostatic system not only leverages 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
• SEM high pressure hose provides reliability and durability. SEM 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
