The G4804BII mild hybrid mixer truck adopts the Sinotruk HOWO TX chassis, equipped with a 350-horsepower engine, a 55kW drive motor, and a battery pack. The reducer is directly driven by the motor, featuring strong power, high efficiency, and fewer failure points. It can achieve functions such as engine shutdown during material waiting, using the air conditioner when the engine is off, and maintaining a constant rotational speed of the drum during driving, saving more than 15% of the comprehensive fuel consumption. At the same time, it has the function of brake energy recovery, saving fuel costs, reducing the wear of brake pads, and saving maintenance costs. The upper mixing drum is made of high-strength and wear-resistant plates, and wear-resistant strips are welded to the blades, which can extend the service life of the drum. The rectangular tubes of the sub-frame are made of high-quality chassis girder steel, which is more reliable and durable. Both the drum and the sub-frame are welded by robots automatically, ensuring high-quality welds. In addition, options such as cold region packages, oxygen generators, side-mounted receiving hoppers, and special painting schemes are available to meet the usage requirements of different customers.
