1. Power System
The power system of a construction vehicle refers to its source of power. Generally, there are two types of power systems for construction vehicles: internal combustion engines and electric motors. An internal combustion engine is an engine that uses fuel such as oil or natural gas to generate energy through combustion. An electric motor is a power system that uses electrical energy to drive an electric motor, achieving rotation or propulsion. Internal combustion engines are more widely used in construction vehicles, primarily due to their high power and suitability for a variety of environments and applications, while electric motors are more suitable for certain specialized operating conditions, such as indoor operations.
2. Drive System
The drive system of a construction vehicle refers to its propulsion method. Generally, there are two types of drive systems for construction vehicles: wheeled and tracked. Wheeled construction vehicles are primarily used in municipal construction and construction projects, such as cement pavements, cement plants, and asphalt mixing plants, while tracked construction vehicles are primarily used in specialized operating areas, such as earthmoving projects, mines, forests, peatlands, and deserts.
3. Working Attachment
The working attachment of a construction vehicle refers to its operating components. Typically, the working devices of an engineering vehicle include an excavator, a shovel loader, a grader, a roller, and a crusher. The excavator is one of the most basic and commonly used devices on an engineering vehicle, primarily used for digging, excavating, and compacting. The shovel loader is suitable for clearing roads, loading materials, and removing accumulated debris. The roller is primarily used for compacting asphalt or concrete pavement.
