460 HP Crawler Medium Bulldozer
SD46-6 crawler bulldozer adopts working device controlled by PPC pilot proportional valve, K-suspension floating walking system, global intelligent service system, rollover protection and falling object protection device, which has the advantages of advanced structure, strong adaptability to working conditions and high working efficiency. It is especially suitable for working conditions such as earthwork mining and rock stripping in mining, construction and other projects.
Electric power system
Cummins KTA19-C525 turbocharged diesel engine is powerful, efficient and energy-saving.
Integrated design of cylinder block and cylinder cover can effectively avoid water leakage and oil leakage.
Compared with similar products, the number of parts is less than 25%, the failure rate is greatly reduced, the maintenance cost is lower, and the maintenance time is saved by more than 50%.
Transfer system
Reliable power shift gearbox and planetary main reducer can transmit power efficiently. Great power, high durability and high production efficiency.
According to the change of external load, it has high fuel economy.
Hydraulic components can absorb the impact load of transmission device, which can improve the life of engine by 1.5~2 times. .
The gearbox adopts multi-disc clutch, hydraulic combination and forced lubrication, and the central transmission adopts spiral bevel gear and splash lubrication.
Working hydraulic system
The cylinder with new structure, seals and hydraulic hoses at key parts are imported products.
The service life and reliability are higher. External working valve makes maintenance more convenient.
Structure
The main frame of full box structure is made of high-performance materials and high-strength castings, which has high impact load and bending and torsion resistance. The supporting equipment runs continuously with high strength under bad working conditions, and high-quality welds ensure the whole life cycle of the main frame.
Chassis system
K suspension floating drive system and pivot chassis structure can effectively reduce the impact of impact load on transmission system and improve the traction performance and service life of vehicles.
The advanced damping system can effectively absorb the impact load and improve the stability of the whole vehicle under complex working conditions.
The main joint type sealed lubricating crawler has long service life and convenient disassembly.
Driving environment
The cab has beautiful appearance, huge internal space and wide field of vision. The installed shock absorber can reduce vibration, and at the same time, with the air conditioning system, the operator is safer and more comfortable in his work.
The dashboard is cast as a whole, which makes the layout of electricity, instruments and air conditioning reasonable and beautiful.
According to ergonomics, the driver's seat and armrest can be easily adjusted up and down. Speed change, steering and throttle control are placed on the left, and working device control is placed on the right. PPC pilot control system is adopted to make the control process more flexible and reduce fatigue.
Work tool accessories
The front working device is a standard semi-U-shaped shovel blade, a high-strength box structure and a high-performance material.
Ensure that the blade has strong cutting force and excellent durability, and can cope with various complex working environments. 16m super-large capacity electric shovel is an ideal and efficient operation equipment for earthwork construction and bulk material shoveling.
The rear working device is a single-tooth scarifier with adjustable angle, which has super penetration and high strength.
The beam, bracket, toothed bar and tooth tip are heat-treated through multiple procedures, so the reliability and service life are more durable. It can be used not only for loosening clay and hardening frozen soil, but also for stripping hard working surfaces, such as gravels, hardened salt mines and strata developed in layers.
Security
Safety warning lights, reversing alarm bells, horns, good braking and special painting of the whole machine effectively protect the safety of surrounding personnel and improve the safety of all-weather operation: safety belts, a large number of handrails and safety signs of the whole machine provide safety protection for operators.
The side guard can effectively protect the engine and radiator from being blocked and damaged by external particles, making the whole machine more beautiful.
Standard antifreeze can raise the boiling point, lower the freezing point, effectively prevent the engine and radiator from producing scale, which is beneficial to the cooling and protection of the engine.
In addition, an anti-overturning frame with anti-rolling and anti-falling functions can be selected to avoid the injury of accidents to operators.
