When choosing the chassis, it is generally considered according to economic benefits, such as: the price of the chassis, loading quality, overloading capacity, 100 kilometers of fuel consumption, 100 kilometers of fuel consumption, and so on.
(1) chassis frame upper plane height above the ground. General 6×4 chassis frame height above the ground for 1050 ~ 1200. the larger the value of the vehicle center of gravity, the higher, the more likely to cause rollover. Factors affecting this value are mainly tire diameter, suspension arrangement and the main frame section height;
(2) Chassis rear suspension. The value is too large to affect the dump truck lifting stability, resulting in lifting overturning accidents. This value is generally between 500-1100 (except for side dump truck);
(3) The whole vehicle is reasonably matched and reliable.
HOWO dump truck Upholstery
(1) Carriage
The choice of carriages is mainly from the aspect of materials, choosing 16Mn material to be better than ordinary A3 material strength, but the cost is also high. According to the transportation of different goods to increase the thickness of the appropriate local to meet the requirements.
HOWO dump truck common transportation cargo compartment thickness
Cargo Bottom plate thickness (unit: mm) Side plate thickness (unit: mm)
Earth and stone 8 ;4
Construction waste 10 ;6 Optional bucket compartment
Large (ore) stone 12 ;8 Optional bucket compartment
Coal 6 ;4 Specialized media wagon
Clay 8 ;4
Iron ore powder 10 8 Iron ore powder special transportation vehicle
Grain,;fertilizer 6 4
In order to reduce the weight of the carriages, some carriages can be made of aluminum alloy or high-strength materials to reduce the deadweight and increase the load capacity.
(2) Selection of lifting mechanism
1. General-purpose dump trucks are recommended to choose tripod enlarged lifting mechanism, which is suitable for dump trucks with the length of 4~6 meters;
2. Reasonable arrangement, the force of each component will not exceed the capacity of the component, and the system oil pressure is small to ensure the service life of each seal;
3. Choose high quality hydraulic cylinder. Hydraulic cylinder is the power part of dump truck lifting, try to choose the products with quality assurance;
4. Dump trucks with a length of more than 6 meters generally use multi-stage cylinder front-roof lifting structure;
5. Double-cylinder lifting structure is generally used for the wheelbase of 3 to 4 meters of the dump truck.
