Hydraulic excavator test trainer

P.N.:GTMT-0003

Product description

Hydraulic excavator is widely used in engineering construction, road construction, hydraulic engineering, defense construction and other earthwork construction and mining operations. At present, almost all hydraulic excavators use hydraulic transmission. Compared with mechanical excavators, hydraulic test excavators have the advantages of small size, light weight, flexible operation, sensor detection and wireless control, and easy for overload protection and long-distance operation.

In recent years, the application of high-tech microelectronics technology in hydraulic technology constantly increasing integrated technologies level for engineering machinery and construction machinery, improving the reliability, operation safety, comfort, and longevity of these machines, and making wide applicability.

The excavator trainer displays the structure and working principle of hydraulic excavator, easy for student’s understanding and hands on operation.

Main feature

1. The wireless control and wireless acquisition of testing excavator are easy for control.

2. The hydraulic system and electrical control are under-mounted. The whole structure is

compact, coordinated, and the layout is practical, available for 4-6 people for experiments.

3. The excavation machinery is made by the physical structure and the reduced proportion. During 

    the experiment, the hydraulic system is started to simulate the operation of the excavator according 

    to experimental requirements.

4. The trainer is made by the physical structure and proportion, when testing performance data, it can truly 

    reflect the actual mechanical working conditions, the students can deeply understand the structure and 

    working principle of the parts in experiment.

5. The experimental components are made of pressure resistant hose, the pressure up to 25Mpa.

6. With three-phase leakage protection, the output voltage 380V/220V, power supply

disconnected when more than 30mA leakage happens;

electrical control uses DC 24V power supply with over-voltage protection, prevent the

device damage by wrong operation.
