Program Description:
This program has been designed to meet the training needs of the local labor market by taking
into considerations the National Occupational Skill Standards (NOSS) for heavy equipment
"technician" Trade. The training in this program includes general skills in English Language,
Mathematics, Physics, as well as Human Communication Skills. Also, the program includes
training on basic skills related to heavy equipment systems and components and their operation,
and the fundamentals of heavy equipment electrical and electronic systems that would help the
trainee in his career. In addition, the program provides specialized skills in the field of heavy
equipment mechanics related to maintenance and repair techniques of heavy equipment
mechanical components and systems after performing set of technical tests on the heavy
equipment. The training on how to set diagnostic strategies for the mechanical faults in heavy
equipment would also be given.
In Technical Colleges, training on “heavy equipment Technology” is performed through
(1742) contact hours, in addition to (420) hours of cooperative-training in the labor market
through cooperation between the colleges and industrial establishments, governmental and
private sectors (like heavy equipment dealers) that work fully or partially in heavy equipment
sector.
The graduate of this program is awarded an associate degree certificate, and expected to work
as a technician in civil and military establishments linked to heavy equipment.
General Objective:
This program aims at providing the trainee with hands on skills, experience and necessary
information required to exercise work as a technician in the field of heavy equipment.
Detailed Objectives:
By the end of this program the trainee will be able to efficiently perform the following:
1) Follow up safety procedures and instructions on heavy equipment workshops before
commencement of any job.
2) Recognize basic heavy equipment systems and components, functions and methods of
operation.
3) Use different specialized tools in heavy equipment field to perform necessary tests on
heavy equipment systems and components.
4) Use maintenance and service manuals of different heavy equipment models and deal with
heavy equipment spare parts.
5) Execute maintenance and repair operations on heavy equipment systems and components
with related skills of assembly and disassembly.
6) Set up diagnostic strategies for the mechanical faults in heavy equipment systems and
components.
