General-purpose vehicles refer to vehicles used for transportation and various operations. There are box-type, tank-type, dump-type, storage-type, grille-type and truss-type compartments for general-purpose vehicles, which can transport goods with different properties, states and requirements, such as liquid, gas and bulk powdery or granular solid goods. Livestock, poultry, fresh fish and other animals; Goods that need to be kept warm, fresh and refrigerated; Toxic, flammable and explosive dangerous goods. In countries with large automobile production, there are also special vehicles with double compartments to transport 8 ~ 10 vehicles.
Another general-purpose vehicle is engaged in specialized operations. In order to achieve different purposes, this vehicle is equipped with corresponding operating equipment on the chassis, such as trucks, garbage trucks, sweepers, sprinklers, environmental monitoring vehicles, cement mixers, truck cranes, power station vehicles, emergency repair vehicles, exploration vehicles, reservoir fracturing vehicles, scientific research vehicles, police cars, fire engines, aircraft tractors, refueling vehicles, charging vehicles, air compressors, ambulances, medical facilities vehicles and so on.
Industrial and mining production vehicles are specially designed and have their own series, which are generally used for special roads or specific areas. It can be divided into dump trucks for mining, hydraulic engineering and construction, with a load of 20 ~ 300 tons, 185 ~ 1200 kW high-speed diesel engine, suspension with oil, gas, silicone oil or rubber as medium, and box longitudinal beam (made of low alloy). The steering system is hydraulically assisted. Large-tonnage dump trucks are also equipped with emergency steering pumps. The braking system is operated by power with emergency braking device. The large-tonnage dump truck is also equipped with a hydraulic reducer. Most of these cars are rear-dump. Because this kind of car often works in harsh environment, the cab should be sealed, equipped with protective plates, and some should be equipped with air conditioning equipment.
In addition, there are special transport vehicles for transporting steel, ladle, hot ingot and steel in metallurgical plants, with a loading capacity of 30 ~ 500 tons. The speed of this car is not high, and the engine power does not need to be large (150 ~ 275 kW), but the turning radius is small, and the cab is safe and insulated. (3) Flat-bed transport vehicles used in shipyards or used to transport large-scale equipment can transport large-scale equipment such as hull, transformer, power generation equipment or chemical distillation column welded in sections. The top of this car is a big flat plate, and all the mechanisms and cab are under the flat plate.
