Product Description

Hydrostatic transmission technology

The upgraded hydrostatic system not only inherits the automatic double-circuit electronically controlled hydrostatic transmission technology of third-generation bulldozer, but also improves efficiency and reliability

• The driving pump and travel motor of Germany Rexroth's new generation integral and integrated control valve are adopted to simplify the pipeline design and further improve the reliability 
• High pressure hose, reliable and durable. Control technology, precise control, high transmission efficiency
• The hydrostatic oil tank and the working hydraulic oil tank are combined into one, which improves the filtration accuracy and cooling capacity of the hydraulic system, improves reliability, and reduces maintenance costs
• Eliminate torque converter, gearbox and rear axle box, saving 60% in maintenance costs
• In-situ steering, power steering, infinitely variable speed, saving working time and greatly speeding up work efficiency 

easy operation

Multi-functional electronically controlled travel handle to realize spot steering, power steering and cruise control

• Cruise control - press the yellow button for 5 seconds to realize automatic operation at the set speed, freeing the driver's hands and making the operation easier
• Steering in situ - move the walking handle to the left/right to the end to realize in situ steering in the corresponding direction
• Power Steering - automatic, more dynamic load steering

Hydraulic pilot control, easy to operate
Precise Control of Jobs
The electronically controlled engine with high torque reserve coefficient can realize real-time switching of three modes of economy/standard and heavy load under any working condition through a multi-state switch to meet the requirements of different working conditions
The electronically controlled engine continuously variable speed knob can realize precise control of engine speed, and the engine can walk at low speed
Accelerator pedal selection mode, which can only reduce the vehicle speed while keeping the engine speed constant, which is more convenient for the engine power to be exerted
The steering mode can realize fast and slow steering to meet the different needs of the operator

Large capacity SU shovel

The standard configuration is the most popular SU shovel of the family, with a large capacity, which is 26% higher than that in the industry year-on-year

• The SU shovel combines the advantages of the straight shovel and the U-shaped shovel. It not only has the leveling function of the straight shovel, but also is compatible with the large capacity of the U-shaped shovel.
• L-shaped push arm, the push arm on each side is connected with the push rod to form the switch of the English letter L, which reduces the use of castings and forgings and has higher strength
• The blade adopts a box structure, and the stress point is additionally reinforced for higher strength
• Optional double link push arm

Long-life four-wheel belt

• Four-wheel and one-belt products, high reliability, long life, provide a variety of track shoe configurations to meet different application conditions
• Lubricating oil is sealed in the copper sleeve, and the carrier sprocket, track roller and idler are free of maintenance for life
• The final drive adopts one-stage straight teeth plus one-stage planetary transmission (two-stage straight teeth are commonly used in the industry), with large transmission ratio, high speed ratio, high transmission efficiency and low maintenance cost
• The braking system adopts wet multi-plate friction plates, which doubles the reliability
• Designs Final Drives to Twice the Reliability

Finite Element Analysis of Structural Parts

• Use the bulldozer database information to conduct FEA (finite element) strength and fatigue life analysis on all structural parts, and check the analysis through OMSA (stress test analysis on the whole machine) test for the stress concentration position, which greatly enhances the structure strength and service life
• Welding technology for structural parts eliminates weld stress

Modular Cooling System

• Optimized heat dissipation of the water tank and hydraulic oil radiator, higher efficiency, and can meet the environmental capacity of 43 degrees Celsius
• Modular design, easy to disassemble, the oil cooler can provide heat dissipation for the hydrostatic system and the working hydraulic system at the same time
• The louver-type front grille has a good heat dissipation effect and can be opened in one direction, making maintenance more convenient
• The desert type can be equipped with a sand shield to improve the service life of the radiator

maintenance

• ECM fault diagnosis system, optional fault code display
• Lifetime maintenance-free support rollers, carrier sprockets and idlers
• Eliminates torque converter, gearbox and rear axle box, reducing maintenance costs
• The hydrostatic oil replacement cycle is 2000 hours, reducing maintenance costs
• The working valve is placed outside the hydraulic oil tank for easy inspection and maintenance
• Three-level alarm system, automatic fault diagnosis
• Add P/S/E power mode indicator switch
