HYDRAULICS TRAINING

Model RSA-02

The model RSA-02 was developed together with Instructors who have more than twenty years experience in teaching and designing hydraulic systems for the local market and who are accredited trade test providers. Special attention has been given to the requirements of Trade test preparation.

This ensures that no extra burdensome theory is presented and leads on to the eventual Trade Test training.

The “One Touch” system of placing components is recognized as the simplest and most convenient in the market. Its dimensions allow it to be used with most trainers on the market, and has the advantage of holding most components in a horizontal or vertical position.

Learning Sequence

Study of components: From introductory to advanced: Operation of

Components – Basic – Trade Test – Intermediate – Advanced - Electro – Proportional – etc., with entry at any stage
