Product Description

SEM 220HP hydraulic track dozer crawler bulldozer (SEM822D)
 

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
