Hydrostatic transmission technology

The closed dual-circuit electronically controlled hydrostatic transmission system inherited from the third generation of Cat bulldozers has high working efficiency.
The German Rexroth drive pump, drive motor, and Cat high-pressure oil pipe are selected for high reliability and long service life; Cat control technology, precise control and high transmission efficiency.
In-situ steering, power steering, stepless speed change, save working time and greatly speed up work efficiency.
Eliminates torque converter, gearbox and rear axle box, saving 60% in maintenance costs.

Easy operation

Multi-function electronically controlled walking handle for in-situ steering, power steering and cruise control.
Cruise control – press the yellow handle for 5 seconds to automate the operation at the set speed, freeing the driver’s hands and making the operation easier.
Steering in situ – Toggle the walking handle to the left/right to the end to achieve in situ steering in the corresponding direction
Power steering – automatic realization, load steering power is more powerful.
The electronically controlled engine with high torque reserve factor can switch between three modes of economy/standard and heavy duty in real time under any working conditions through the multi-state switch to meet the requirements of different working conditions.
Accelerator pedal selection mode, which can only reduce the vehicle speed while keeping the engine speed unchanged, which is more convenient for the exertion of engine power.
The stepless speed change knob of the electronically controlled engine can realize precise control of the engine speed, and the engine can walk at low speed.
Steering mode, which can realize fast and slow steering to meet the different requirements of operators.
Hydraulic pilot control, easy to operate.
Precise control of the job.

Large capacity SU shovel

Standard Cat family’s most popular SU shovel, large capacity.
SU shovel combines the advantages of straight shovel and U-shaped shovel, not only has the function of straight shovel leveling, but also is compatible with the characteristics of U-shaped shovel’s strong soil collecting ability.
Cat technology L-shaped push arm, with high structural strength, the blade is close to the fuselage and the thrust is more stable.
The blade adopts a box-type structure, and the blade joint is reinforced design to ensure the strength of the blade

Finite Element Analysis of Structural Components

Use the Cat bulldozer database information to perform FEA (strength, fatigue life) analysis on all structural parts, and conduct OMSA (stress strain test) analysis and check for stress concentration locations to ensure structural strength and service life.
Adopt Cat structural parts welding process to eliminate weld stress and further improve structural strength.

Modular Cooling System

Equipped with a hydraulic temperature-controlled fan as standard, the fan speed can be adjusted according to environmental needs, with automatic fan reversal function, the reversal time interval can be set by yourself, and a manual reversal function is added, which saves fuel consumption and facilitates radiator cleaning.
Modular design, easy to disassemble, easy to maintain, only need to replace the corresponding module louvered front grille after damage, which can be opened in one direction, good heat dissipation effect and easy maintenance.
With low temperature start function, it is convenient for the whole machine to start in low temperature environment.
Standard 50°C high temperature ambient cooling package.

Maintenance

Eliminate transmission components such as torque converter, gearbox and rear axle box, reducing maintenance costs.
Cat ECM fault diagnosis system, automatic diagnosis of the whole vehicle electrical system fault.
The hydrostatic oil replacement cycle is 2000 hours, reducing the cost of use.
Three-level alarm system, automatic fault diagnosis.
External working valve for easy inspection and maintenance.
