Presented by the late Garnett Cross who was an industry leader in hydraulics.

Garnett provided in-person training and consulting for 47 years - 1974 - 2021. His clients included the major corporations in manufacturing, mining, military, shipping and rail.

The training has helped many organizations resolve expensive downtime and ongoing maintenance costs. In addition to the course material, Garnett will share some of my consulting experiences helping get plants back online and resolve ongoing maintenance costs.

Students from many countries have attended the courses including African states, United States, Emirates, Indonesia, and Europe.

The presentations include animated PowerPoint slides and demonstrations of hydraulic components.

Calculations are provided using metric units.

The course topics include:

• Principles of Hydraulics

• Compressibility of Hydraulic Fluid

• Hydraulic Symbols

• Two Cylinder Problem

• Cleanliness of Oil

• Cleanliness continued

• Hydraulic and Mechanical Leverage

• Design of Cylinders

• Cylinders Oil Capacity

• Cylinders in Parallel

• Components of a Hydraulic Circuit

• Sizing Check-list

• Pipe sizes for 90 litres/minute

• Pipe sizing with respect to turbulence of fluid

• and Reynolds number

• Hydrostatic Drives

• Couplings and Reservoirs

• Hose Identification and Couplings

• Check Valves and Cartridge Valves

• Pilot Operated Check Valves

• Flow Control Valves

• Pre-fill Valves

• Directional Control Valves

• Solenoid Valves

• Solenoid operated valves with orifice

• Externally piloted system with throttle plate

• Gasket mounted relief valve

• Unloading Valve

• Fault Finding

• Sequence Valve

• Sequencing cylinders with sequence valves

• Sequence and pressure reducing valves

• Over center valve with hydraulic motor

• Vane pump

• Accumulators

At the end of the course two lectures are provided covering field experience and safety ideas for hydraulic systems.

The course includes resources which can be downloaded for future reference.

An advanced hydraulics course is available, this will help engineers, draftsmen and foremen in the design of hydraulic systems.
