Improved by 40%. Cooling ability is enhanced with a hot air reflow isolating device, optimal thermal dissipation duct, and aluminium plate-fin type radiator, ensuring engine reliability. An automotive-type oil filling cap and optimally structured oil filling channel enhance the entire truck’s safety. A constant displacement pump load sensing steering system increases lifting speed and reduces hydraulic oil temperature. Key components like the frame, mast, overhead guard, and steering axle are optimally designed, improving overall safety and reliability. Retropositioning the truck’s centre of gravity improves loading capacity, stability, and safety.
