Caterpillar 220HP (Sem822LGP) Bulldozer with Weichai Engine
Advantages
Efficient: The electronically controlled hydrostatic drive system and multi functional joystick provide high levels of performance and maneuverability
Comfortable Operation: The cabin is ergonomically designed for increased operator comfort and visibility. The advanced monitoring system tracks machine operating conditions and keeps the operator informed of all vital machines functions
Reliable: The proven hydrostat design along with world class pump and motors provide a highly reliable tractor. The undercarriage components are designed for longer life versus the leading competitor
Serviceability: The SEM tractors are designed for easy access to reduce overall maintenance time. The machines electronic control module allows for quick troubleshooting
Cat ® Product Link™
- Cat ® Product Link™ will support your business, and accurately convey information of the equipment to relevant personnel in a timely and effective manner for your better equipment management
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
