Sometimes 10 Year major inspections show us some very worn parts, this is what a drum looks like when it has rope damage.
Major inspections form a crucial part of maintenance and stipulated in AS2550.1-2011:
9.4.1 General
The major assessment shall contain both—
(a) a theoretical part, where the remaining design life of each component of the crane is
analysed based on the duty estimation; and
(b) a practical part, where physical inspections of all critical components and systems of
the crane are inspected for integrity and functionality.
Upon checking the remaining life of the critical components, the competent person shall
identify components that have reached their design life that require overhaul for future safe
use.
