New upgrade - superior performance

1. Powertrain:

• Equipped with Isuzu 4JG3X engine, the fixed power of 55kW, the power surplus is more sufficient, and the hydraulic power is not reduced below 4000m plateau. With high-pressure co-rail technology, fuel consumption is lower.

• Mature DPF post-treatment + 8 hours automatic regeneration control strategy, to ensure that the accumulation of particles in a low state, reduce the number of standby manual regeneration, worry and durable.

2. DPD + EGR technical route:

• Part of the exhaust gas is recirculated into the gas admittance system, where it is mixed with fresh air and burned to suppress NOX production.

• EGR is upgraded from tubular to laminated, cooling faster.

3. Hydraulic system:

• With a load-sensitive system, the operation efficiency is higher, the control performance is better, and the flat surface performance is superior.

• The main valve diameter is increased, the pressure loss is reduced by 15%, the valve oil channel is optimized, the liquid power is reduced, and the operation energy efficiency is greatly improved.

Optimization of structural components - durability

1. Arm, pole, and shovel upgrades:

• The axial length of the moving arm body is increased, the stiffness is increased and the reliability is greater. Optimize the position of the butter mouth of the braid from the side to the lower side of the braide for easy maintenance.

• The bucket is widened and the bucket capacity is increased to 0.3 m3; Optimize the barrel structure and increase the lifetime; The material of the bucket ear plate is upgraded to G70 / Q460C, and the wear resistance is greatly improved.

2. The bulldozers escalated

• The shovel is lengthened and lifted, the height increased to 480 mm, and the angle increased to 28.5 °, eliminating walking obstacles.

3. Get off the chassis to strengthen

• The reinforced integral welded X-shaped lower frame has more advantages in safety and reliability than H-shaped, and extends service life.

Upgrade the driver's room - a new experience

1. Sealing improvements:

• Using a modular perforation design of wire duct ducts, an upgrade of sealing tape, a secondary filling of unwelded areas, etc., the cabin sealing is greatly improved to solve the dust annoyance.

2. Air conditioning upgrades:

• Automotive-grade vents are used to optimize the position of air conditioning vents and are more ergonomic, and are controlled from head to toe at a constant temperature.

The 3.7-inch smart touch screen:

4. Interior upgrades:

• The interior is designed in a new way, with the water cup positioned in front of the right lever to reduce wind tunnel space on the right side. The multi-function panel, one button to start the machine and the throttle knob two is made one, the standard equipment water cup, 12V power supply port, USB interface and so on, more humanized.

5. Deep mining field optimization:

• The beam of the front window of the driving room is moved down 117 mm, and the view of the deep excavation is better.

6. Human / Mechanical Engineering Analysis Assistance Design

• The thick waist support on both sides of the back is designed to increase waist support and reduce spinal burden. It is easier to ride. Back and rear, hand support, back and headrest are adjusted in 8 directions. Comfort is better. Universality is good
