| • This is a flexible electro hydraulics teaching system, with aluminium profiles and powder coated sheet |
| steel as the frame material, universal and silent castors are adopted to achieve movable ability. |
| • Quick mounting system is adopted to realize all components to be mounted easily and securely |
| on the grooved profile plate in any direction without tools. The connection between hydraulic tube |
| and hydraulic components is achieved by fast connecting and self-sealing couplings without |
| leakage, thanks to its lockable and spring design, the insertion of hydraulic tubes can be realized |
| simply by pushing the female coupling only and the extraction can be achieved easily by pulling the |
| spring ring with one hand. |
| • The electrical units are clamped into the top frame and sequenced individually, the supports and |
| the electrical units are the same for both hydraulics and pneumatics, single investment with double |
| the functionality. |
| • A variety of hydraulic and electrical/electronics parts are available for experiment extension, help |
| achieve skills of different levels from elementary to advanced hydraulic engineering. |
