Gearbox Maintenance

In general the gearbox or speed and torque change devise is as important as any other vital part of machinery as its malfunction would affect the entire process in which it is employed.

This 3 day course is designed to provide engineers and superintendents, with a practical working knowledge of Gears and Gearbox Maintenance.

The course is intended to provide the understanding to adopt best practices in maintaining geared systems, identify potential problems, and ensure proper repair procedures and quality
measures.
