Chapter Four Overhaul and Maintenance
Overhaul is divided into daily overhaul and regular overhaul. Inspectors must prepare
overhaul plans and carry out overhaul. Please refer to the table below for overhaul items and
overhaul periods.
In addition, the overhaul must be carried out every 40,000 hours of work or every 8 years
(the principle of choosing which way to reach the deadline first). The overhaul period is based on
the handling operation. It is recommended to implement maintenance and overhaul in a period of
about 1/2 for high strength and frequency operations.
In addition, if the inspection and adjustment method is unclear, please contact the company
service department.
