The exercise books are tailored to the device sets. These device sets build on the contents and knowledge from the "On/off hydraulics – Manual operation (BIBB, A-H)" and "Mobile hydraulics – Throttle and load-sensing control systems" learning topics.

The described exercises and tasks provide basic information and methods. The setup is structured in a uniform manner and provides the step-by-step description for completion of the individual exercises.

The following exercises are included:

No. Exercise
01 Pressure setting and hydraulic pilot control
02 Setting actuator quantities by means of stroke limitations
03 Influence of pipelines
04 Influence of loads
05 Stroke limitation with changing direction of force
06 Boom cylinder with external force effect
07 LUDV system

With the help of logically structured, practice-related exercises, the trainee shall learn the following:

  • understand physical laws of hydraulics such as pressure difference, opening cross-section and flow,
  • get to know and use specific graphical symbols,
  • understand the function of the LUDV control,
  • Get to know components such as 4/3 directional control valve, load holding valve, primary and outlet pressure valve, pressure compensator, hydraulic pilot control,
  • understand the connection between control and velocity,
  • get to know the function of the LUDV control in parallel operation,
  • work out the function and application of the hydraulic pilot control,
  • determine characteristic values and derive characteristic curves from them.
