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.
Cummins KTA19-C525 turbocharged diesel engine is powerful, efficient and energy-saving.
The cylinder block and cylinder head are designed inanintegrated way to effectively avoid water leakage andoilleakage.
Compared with similar products, the number of partsislessthan 25%, the failure rate is greatly reduced, the maintenancecost is lower, and the maintenance time is saved by morethan50%.
Reliable power shift gearbox and final drive of planetarystructure can be transmitted efficiently.Power, high durability and high production efficiency.
According to the change of external load, it has high fueleconomy.
Hydraulic components can absorb the impact load of thetransmission device, which can increase the life of theengineby 1.5~2 times.
The gearbox adopts multi-disc clutch, hydraulic combinationand forced lubrication, and the central transmission adoptsspiral bevel gear and splash lubrication
The oil cylinder with new structure is adopted, and the sealsandhydraulic hoses at key parts are imported products.
The service life and reliability are higher. External workingvalve is more convenient for maintenance.
Imported instruments can display data more accurately and intuitively, and can realize electronic monitoring and over-limit alarm for the operation of main components and parameters such as oil temperature, oil level and water temperature, with higher reliability.
The main frame of full-box structure is made of high- performance materials and high-strength castings, which has high capacity of bearing impact load and resisting bending and torsion, supports equipment to carry out high-strength continuous operation under harsh working conditions, and high-quality welds ensure the whole life cycle of the main frame.
K suspension floating driving system and pivot chassis structure can effectively reduce the impact of impact load on the transmission system and improve the traction performance and service life of the vehicle.
Advanced shock absorption system can effectively absorb impact load and improve the stability of the whole vehicle under complex working conditions.
The main joint type sealed and lubricated crawler belt has long service life and convenient disassembly and assembly.
The cab is beautiful in shape, with 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 operators are safer and more comfortable in their work.
The instrument panel is cast integrally, which makes the layout of electrical, instrument 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 control system is adopted to make the control process more light and flexible and reduce fatigue
The front working device is the standard semi-U-shaped shovel blade, high-strength box structure and high-performance materials. Ensure that the blade has strong cutting force and excellent durability, and can cope with various complex working environments. 16m³ super-capacity shovel is an ideal and efficient operation device for earthworkconstruction and bulk material shoveling.
The rear working device is a single tooth scarifier with adjustableangle, which has super penetration and high strength.
Safety warning light, reversing alarm bell, horn, good braking and distinctive painting of the whole machine effectively protect the safety of peripheral personnel and improve the safety guarantee of all-weather operation: seat belts, a large number of handrails and safety signs of the whole machine provide safety protection for operators.
The side shield can effectively protect the engine and radiator from blockage and damage caused by external particles, making the whole machine more beautiful.
The standard antifreeze can raise the boiling point and lower the freezing point, effectively prevent the engine and radiator from generating scale, which is beneficial to the cooling and protection of the engine.
In addition, an anti-overturning frame with anti-tumbling and anti-falling functions can be optionally installed to avoid the injury of accidents to operators.
Eye-catching signs accurately remind the owner to carry out correct maintenance, and the battery is maintenance-free: the open hoodfullyexposes the internal components, making it easy to carry out inspection and maintenance.
Because of its high reliability and long mean time between failures, the cost of use and maintenance is lower than that of other manufacturers.
Platinum's perfect service network and timely and thoughtful enthusiastic service are the intimate guarantee for you to use theequipment with peace of mind. The durable product quality meetsyour expectations of Shanplatinum equipment.
