Excavator is the main machine in mechanical engineering, it is widely used in engineering construction, construction road construction, hydraulic engineering, national defense engineering and other industries such as earthwork construction and mining excavation. The hydraulic excavator simulation model has the advantages of small size, light weight, convenient operation and long-distance operation. Its purpose is to guide students to actively think, innovate design, and cultivate students’ comprehensive design ability and practical ability. A new comprehensive experimental platform equipment.

1. The electrical operation control is side-mounted, and the hydraulic station is placed at the bottom of the hydraulic platform. The overall structure is compact and coordinated, beautiful, and strong.

2. The excavating machinery is manufactured in a reduced scale according to the actual structure, simulating the on-site operation, which can truly reflect the actual working conditions of the machinery, so that students can understand the structure and working principle of each part of the machinery in practice, and the experimental control adopts the cross joystick control;

3. The experimental parts adopt pressure-resistant hoses, the hydraulic components adopt domestic brands in China and Germany, and the pump station adopts variable vane pumps.

4. With three-phase leakage protection, the output voltage is 380v/220v, with leakage protection, the electrical control adopts DC 24v, and there is overvoltage protection to prevent accidental damage to the equipment
