Product Description

SEM Brand New SEM822D 220HP 230HP Crawler Bulldozer

Product Description

<sub>Hydrostatic transmission technology
* Use German drive pump, drive motor, high-pressure tubing, high reliability, long life; control technology, precise control,
high transmission efficiency
* In-situ steering, power steering, stepless speed change, saving working time and greatly speeding up work efficiency
* Eliminates torque converter, gearbox and rear axle box, saving 60% of maintenance costs

Easy operation
* Multifunctional electronically controlled walking handle, realizing in-situ steering, power steering and cruise control
* The electronically controlled engine with high torque reserve coefficient can realize real-time switching of economy/standard
and heavy load three modes under any working conditions through multi-state switches to meet the requirements of different
working conditions
* The accelerator pedal selection mode can reduce the vehicle speed while keeping the engine speed unchanged, which is more
convenient for the use of engine power
* The electronically controlled engine stepless variable speed knob can realize precise control of the engine speed, and the
engine can run at low speed
* Steering mode can realize fast and slow steering to meet different requirements of operators
* Hydraulic pilot control, simple and easy operation
* Precise control of operations

Large capacity SU shovel
* The SU shovel combines the advantages of the straight shovel and the U-shaped shovel, which not only has the function of
straight shovel leveling, but also compatible with the U-shaped shovel's strong soil collection ability.
* Technology L-shaped push arm, high structural strength, the blade is close to the fuselage while ensuring more stable thrust
* The shovel blade adopts a box-shaped structure, and the blade joint is strengthened to ensure the strength of the shovel blade

Long-life four-wheel area
* The chassis adopts balance beam pivot suspension, which can effectively reduce the impact on the final drive and increase the
life of the final drive
* Modular final drive design adopts one-stage spur gear plus one-stage planetary transmission, with large transmission ratio and
high transmission efficiency
* Wet friction plate brake, normally closed design, spring compression hydraulic separation, life extension 2 times
* Lifelong maintenance-free design, industry-wide chassis</sub>
