Sanitation garbage trucks have special requirements for chassis technical parameters due to their own particularities, and general-purpose chassis cannot meet the following special needs:

1. Demand for the total mass of the chassis:

In the case of the same model, the maximum total mass of the general chassis is designed to be 5T, and the total mass of the sanitation chassis is designed to be about 7 to 8T. It is necessary to know that the self-mass of the top loading box of the sanitation garbage truck needs to occupy a part of the total mass, and the user needs to carry a larger mass car, so there is a higher requirement for the total mass.

2. Requirements for the length of the wheelbase:

Sanitation garbage trucks are mostly loaded with solid-liquid mixtures of garbage. Due to the fluidity of liquid objects, the flow of liquid in the box will affect the center of gravity of the box and also affect the vehicle's center of gravity when going up and down, starting, and braking. Movement of the center of gravity. When the center of gravity moves forward, it will cause the front axle to overload; when the center of gravity shifts backwards, it will cause the front axle to have low adhesion or even the front wheel off the ground, which is more dangerous. Therefore, the wheelbase of the sanitation chassis is mostly well-designed Yes, it is neither too long nor too short. But the general chassis is different, because its top loading is not that complicated.

3. Requirements for the space on both sides of the chassis frame:

Because of the installation of the sanitation garbage truck, it is necessary to reserve the position of the hydraulic accessories and the height of the installation box body and facilitate the installation of control valves and other equipment, so the space on both sides of the frame should be as large as possible. If a general-purpose chassis is adopted, not only the space is small, but also accessories such as the battery, fuel tank, and urea tank on the chassis need to be moved later to save space. But the special chassis for environmental sanitation is different, basically it rarely needs to move later.

4. Requirements for tire specifications:

Due to the complexity of the working environment, sanitation garbage trucks have higher requirements for tire specifications, which are generally larger than those of general-purpose chassis.

The above is the reason why sanitation garbage trucks use special chassis for sanitation instead of general chassis. Users must choose sanitation garbage trucks produced by regular manufacturers when purchasing, because irregular manufacturers use general chassis to save costs.
