Dump trucks are widely used in various transportation and construction scenarios with their unique unloading method, and have become one of the indispensable means of transportation in modern society.

1. The structure and working principle of dump trucks

A dump truck is a cargo vehicle with a special structure, usually composed of a chassis, a frame, a carriage, an engine, a hydraulic system, etc. The working principle of a dump truck is to tilt the carriage through the power of the hydraulic system so that the cargo can be unloaded from the carriage. This unique unloading method makes dump trucks very efficient in transporting bulk cargo.

2. Uses and functions of dump trucks

（1）.Cargo transportation: Dump trucks are widely used in logistics, construction, mining and other fields to transport various bulk cargoes. Due to their efficient unloading method, dump trucks have a high transportation efficiency when transporting bulk cargoes.

（2）.Engineering construction: In engineering construction, dump trucks are used in earthwork, infrastructure construction and other scenarios, such as road construction, bridge construction, etc. Dump trucks can quickly transport earthwork and other materials to the construction site, providing strong support for engineering construction.

（3）.Garbage disposal: In the field of garbage disposal, dump trucks also play an important role. By loading garbage into the carriage and then dumping it into a landfill or incineration plant, dump trucks provide a convenient way for urban garbage disposal.

3. Operation and precautions of dump trucks

（1）.Preparation before operation: Before operating a dump truck, carefully check whether all parts of the vehicle are normal and ensure that there is no leakage in the hydraulic system. At the same time, understand the environment and conditions of the work site and choose the appropriate operation method.

（2）.Driving and control: During driving, you should maintain a stable driving posture and pay attention to the road ahead and the surrounding environment. Control the speed according to the actual situation to ensure safety and stability.

（3）.Unloading operation: When performing unloading operations, you should first tilt the carriage, then observe the flow of the goods to ensure that the goods can be unloaded from the carriage smoothly. During operation, you should pay attention to safety to avoid accidental injuries.

（4）.Maintenance and care: Regularly maintain the dump truck, check the status of components such as the hydraulic system, brake system, and tires to ensure the normal operation of the vehicle.
