Machine specifications
1. 178kW@2000rpm low speed engine, standard electromagnetic fan, lower fuel consumption, lower noise, large torque reserve, strong power; Optional oil bath filter, suitable for extremely harsh environment and efficient hydraulic system
2. Load sensing constant variable and shunt hydraulic system, more energy saving, more comfortable operation;
Key hydraulic system components using world famous brand suppliers to ensure high reliability;
High hydraulic tank, ensure the service life of hydraulic pump
3. Fixed-shaft transmission has simple structure, comprehensive upgrade of core parts, higher reliability and longer service life; The optimized torque converter matches the engine more reasonably and has higher efficiency.The structure of single stage three components is simple, the design of core components is strengthened, and the reliability is higher
SO32 drive axle, large bearing capacity, equipped with 10 brake pliers (first 6, then 4), better braking performance, long life,
more safety
4. The cooling system designed with Caterpillar’s proprietary technology is more reliable and has better heat dissipation effect; It can meet the continuous operation at +43°C ambient temperature, and the configuration of high temperature cooling system can meet the requirements of +50°C working environment.The radiator is installed with suspension shock absorber to ensure the reliability under severe turbulence
5. The front and rear frames and working devices have been analyzed by FEA (finite element) and verified by OMSA, and are durable, with longer service life and suitable for heavy-duty working conditions; Upgraded high performance bucket with high load factor; Rubber soft limit is adopted to reduce the impact of steering
6. The transmission torque converter is installed in two parts, which is more convenient for disassembly and maintenance;
Fixed shaft transmission design is simple and reliable, easy to maintain, low maintenance cost
7. The manufacturing process conforms to caterpillar CPS production system requirements;
Reverse alarm, reverse light, to ensure the safety of reversing;
8. The vehicle painting process is environmentally friendly and free from heavy metal pollution
