A: It is equipped with the inline 6 Weichai WP12.420E32 engine with a maximum power of 420 HP and a peak torque of 1750 N·m. It generates sufficient low speed torque and excellent climbing capacity. The mature and durable powertrain achieves favourable fuel consumption and high attendance rate on construction sites.
Q2: What braking configurations are available? Is it safe when travelling downhill under heavy load?
A: It is fitted with a triple braking system consisting of dual circuit air service brake, spring energy storage parking brake and engine exhaust auxiliary brake. It offers high safety factors for downhill heavy load operation and adapts to long downhill conditions at construction sites.
Q3: What are the cab specifications and how about driving comfort?
A: It adopts the NG80B long flat roof cab with a single sleeper, meeting ECE R29 safety standards. Standard configurations include an air suspension seat, heating cooling air conditioner and electric windows to improve comfort during long hour construction site operations.
Q4: What are the functions of the axles and differential lock?
A: The middle and rear axles are 13 ton double reduction drive axles with built in differential locks. On muddy and bumpy construction site roads, the rear axles can be locked to prevent wheel slip and improve the vehicle’s passability over complicated terrain.
