Used SEM816D crawler dozer mining
Product introduction
The upgraded hydrostatic system of SEM816D’s hydrostatic transmission technology not only inherits the automatic double-circuit electronically controlled hydrostatic transmission technology of Caterpillar’s third-generation bulldozer, but also improves the efficiency and reliability. It adopts the drive pump and travel motor of the new generation of integral and integrated control valves from Germany Rexroth, which simplifies pipeline design and further improves reliability.
Product features
1. Easy to operate the multi-functional electric control walking handle to realize in-situ steering, power steering and constant-speed cruising – 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 To meet the requirements of different working conditions, the electronically controlled engine stepless variable speed knob can realize precise control of engine speed, and the walking accelerator pedal selection mode at low engine speed can realize only reducing the vehicle speed while keeping the engine speed constant, which is more convenient for engine power. Steering mode can realize fast and slow steering to meet the different needs of operators
2. The large-capacity SU shovel is equipped with the most popular SU shovel of the Caterpillar family as standard, with a large capacity, which is 26% higher than the same period in the industry. The SU shovel combines the advantages of the straight shovel and the U-shaped shovel. It not only has the function of straight shovel leveling, but also is compatible with the large capacity of the U-shaped shovel.
3. Long-life four-wheel-one-one belt four-wheel-one product with high reliability and long service life. Various track shoe configurations are available to meet different application conditions. Lubricating oil is sealed in copper sleeves, and the carrier sprocket, track roller and guide wheel are maintenance-free for life.
4. Finite element analysis of structural parts Use Caterpillar bulldozer database information to perform 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 structural strength and service life. Caterpillar structural parts welding technology eliminates weld stress
5. Modularized cooling system Optimized water tank heat dissipation and hydraulic oil radiator have higher efficiency and can meet the environmental requirements of 43 degrees Celsius. Modular design of capacity is easy to disassemble. The oil cooler can provide heat dissipation for both the hydrostatic system and the working hydraulic system. The louver-style front grille has a good heat dissipation effect and can be opened in one direction for more convenient maintenance.
6. Maintenance and maintenance Caterpillar ECM fault diagnosis system, optional fault code display Support rollers, carrier sprockets and guide wheels are life-long maintenance-free, saving torque converter, gearbox and rear axle box, reducing maintenance costs Hydrostatic hydraulic oil replacement cycle 2000 hours, reducing maintenance costs The working valve is placed outside the hydraulic oil tank, easy to check and repair.
