Application Scenario Overview

The core function of a dump truck is to control the lifting of the car body through a hydraulic system to achieve rapid unloading operations. The performance of the hydraulic system is directly related to the working efficiency, stability and safety of the vehicle.

The Key Role Of The Hydraulic System

On a dump truck, the hydraulic system is mainly responsible for the lifting and lowering of the car body. The system structure includes a hydraulic pump, a hydraulic cylinder, a multi-way reversing valve, a hydraulic lock, a control handle, an oil return device, etc. An efficient hydraulic system can bring the following advantages:

• Ensure loading and unloading efficiency and increase the frequency of transportation turnover;

• Enhance operational stability and avoid self-sinking of the cylinder during lifting;

• Reduce energy consumption and heat generation, and extend the service life of hydraulic components;

• Improve the safety of the entire vehicle.

Common Industry Problems And Challenges

Although the hydraulic system is the core component of the dump truck, it is easy to encounter the following problems during use:

• Slow lifting or failure to lift, often due to reduced pump efficiency or multi-way valve blockage;

• Shaking or unstable lifting process, related to the sealing of the hydraulic cylinder and oil impurities;

• The cylinder self-sinking problem is serious, and it suddenly falls during unloading, posing a safety hazard;

• The hydraulic system is noisy, especially when fully loaded;

• The hydraulic oil temperature is high and the system heats up quickly, affecting long-term continuous operation.
