ABSTRACT:
Apparatus for training an operator in use of hydraulic and electrohydraulic fluid power systems that includes a vertical panel upstanding from a wheeled base. A first plurality of electrohydraulic devices are mounted on one side of the panel, and second plurality of hydromechanical devices are mounted on the opposing side of the panel. Both of the device pluralities include fluid flow control valves that are distinct from each other between the respective pluralities, and fluid load devices such as rotary hydraulic motors and linear hydraulic cylinders that are shared by the respective pluralities. A fluid power source is carried by the base, as are a multiplicity of hoses for connecting the fluid power source to the devices among either or both of the first and second pluralities. Thus, a hydromechanical trainer and an electrohydraulic trainer are provided in a single device with shared components for loading the valves of the respective training sections, which may be used simultaneously.
