Product Description

Product Description

Heavy Duty 235hp Bulldozer SEM822D with Rear Single Ripper Crawler Dozer

Hydrostatic Drive System

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

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.
