Hydraulics & Pneumatics

Course Overview

The course includes an induction session to welcome and orientate the candidate, and familiarize them with the training centre, health and safety requirements and other important policies and procedures. The training consists of a mix of classroom and workshop sessions and various assessments. Upon successful completion, the candidates will learn to sketch the different circuits and understand them to enhance their existing skills. Moreover, they will learn to plan and carry out the essential maintenance tasks on hydraulics and pneumatics.

The training course is designed for an apprentice or beginner who would like to work as a Mechanical Technician or Maintenance Technician.

The candidate should have basic knowledge and skills in mechanical engineering.

Upon completing the training course, candidates will be awarded a ‘Certificate of Attendance’ from NTI, attested by the Ministry of Manpower.

Generally, the work that the learners are undertaking on the short-courses can be quite intensive so it is important that they stay focused yet, at the same time, enjoy their experience in the centre. The centre will employ different pedagogical strategies to help achieve this and these may consist of the following although this list is not exhaustive: 1. Teacher Centred Methods • Lecture • Explanation • Demonstration • Questioning 2. Active Methods • Discussion • Group Work • Quiz • Simulations 3. Student Centred Methods • Reading • Private Study • Homework • Assignments/projects • Reports • Guided Discovery
