A new look

1. Intelligent:

• The 10-inch screen is once again upgraded to be thinner, brighter and sharper;

• Higher system integration, multi-unit integration of body control and power management, and fewer components;

• Support 4G network OTA upgrade, faster and more secure, add a button call function;

• Night stop lights delay extinguishing, a key switch between the forehand and backhand display screen, rear camera configuration, to ensure safe driving.

2. New interior:

• The interior is fully upgraded, narrow armrest box, minimalist front control box, standard water cup seat, 24V power access port, USB interface, etc., with automotive quality interior.

• Equipped with comfortable shock-reducing seats, vibration comfort improves.

3. Structural upgrade:

4. A new air conditioning system:

• Powered by a new air conditioning system, the air conditioning wind tunnel is optimized, the cooling effect is stronger, and the wind amount is allocated more reasonably. Air conditioning evaporators enable in-car cleaning and maintenance, making cleaning simpler.

5. Exterior upgrade:

• Sany has worked with a well-known automotive design company, and its exterior has been upgraded completely, with a steady and robust style.

• Covered doors are highly designed, and side doors use a automotive double-layer door making process to strengthen.

• The engine casing and toolbox lids are powered by air springs, making the opening process more labor-efficient.

new technology

1. The shovel upgrade:

• The standard rock shovels are optional, and the earth shovels can be equipped to achieve "one condition, one blow" and meet the needs of different working conditions.

• Optimize the shovel hinge point, optimize the shovel thickness, increase the flow of material inflow and reduce friction.

• The angle between the front blade plate and the base plate is increased, increasing the thrust rate.

• Optimize the mining power cloud diagram, reduce the average resistance of the mining process, and increase the mining efficiency.

2. Rod Regeneration and Quick Oil Recovery:

• The light load shaft excavation increased the recovery flow from the small cavity to the large cavity of the cylinder by 30%, reducing the power of the engine.

• When heavy loads are excavated, the small cavity of the cylinder quickly returns oil, saving 18% of the power, faster speed and more fuel efficient.

• When the braid is unloaded, the cavity quickly returns to the fuel tank, reducing pressure loss, and the braid unloading speed is faster and more fuel efficient.

3. DPC technology

• Direct power control technology is used to dynamically adjust according to the load, so that all commonly used work stages are moved to the economic zone, and the power matching achieves "what is needed," reducing waste and achieving energy savings.
