Checks, Valve Adjustments and Maintenance in Mobile Hydraulics
Objectives
At the end of the course, trainees will be able to:
- Understand open circuit operation, technology and control.
- Make effective use of the technical documentation provided by the manufacturer.
- Know how to adjust open-loop controls.
Program
1. HY2 SAFETY: INTERVENTIONS ON MACHINES / INSTALLATIONS THAT ARE NOT LOCKED OUT
- Performance control – Adjustment – Sampling.
- Sub-assembly exchange (Directional control valves – Hydraulic power unit, etc.).
- Separation – Tagout.
2. PRINCIPLES OF CONSTRUCTION AND OPERATION OF MACHINE COMPONENTS / APPLICATIONS
- Pumps and motors: Axial piston and variable displacement systems – Slow-speed engines.
- Controls: Constant pressure and flow (Load-Sensing) – Load-Sensing and power limitation – Constant power
- Electronic power control – Negative control and positive control.
- Directional control valves: 4/3 Load-Sensing (L.S) distribution, open centre and closed centre – Individual balance (Simultaneous movements with or without speed conservation) – Flow-Sharing (L.S) distribution.
- Hydrostatic steering: Load-sensing closed centre
- Steering system – Safety block – Principle of electrohydraulic steering.
- Pressure equipment: Manipulators – Assist pressure – Anti-shock valves with damping – Hose rupture valves – Balancing valves.
- Symbolisation – Cases of application.
- Filtration: Causes and sources of contamination – Role of filtration – Filter positioning (ISO 4413).
3. BUILDING CIRCUITS ON POWER SIMULATORS
- Study of the control and distribution diagram.
- Operating phases.
- Control adjustment procedures: Flow cancellation / Constant pressure (CP) – Load-Sensing – Constant power.

of principals would recommend IFC TRITECH as a training organization.
Quality
This is the percentage of satisfaction obtained after consulting all 2023 trainees on the quality of our training courses.
Pedagogy
This is the score obtained by IFC TRITECH when participants were asked about the suitability of teaching resources for their inter-company training.
Our testimony
We call on IFC TRITECH for training in electricity and hydraulics, so that our technicians can develop their skills in an agile way. IFC TRITECH also provides us with tailor-made training on our runway equipment, which incorporates specific and complex technologies, both in its training centres and on our premises.
All these factors have made IFC TRITECH the preferred training organisation for Air France's ramp equipment division for over 20 years!
For more than 10 years, we have trusted the IFC TRITECH group with our training needs. Their skilled trainers are passionate about their work, which is reflected in the quality of their training courses. Thanks to them, our Loxam technicians develop their knowledge and performance in the field.
For over 20 years, IFC and TRITECH have been the benchmark in the field of hydraulics and lubrication training.
I have met passionate trainers who have enabled me to develop my skills in these areas.
Together with them, we have developed training courses for my employees in the maintenance of unique and complex tools.
