Driving piles with a vibratory hammer can be very hard on a crane boom. So can using the crane boom with a vibratory pile extractor or for dynamic compaction. Given the critical nature of the boom, it must be

(a) inspected

(i) at intervals specified in the manufacturer’s specifications or specifications certified by a professional engineer;
(ii) annually or every 600 operating hours while being used for driving piles with a vibratory hammer; or
(iii) annually or every 200 operating hours if used with a vibratory pile extractor or for dynamic compaction, and

(b) certified by a professional engineer as safe for continued used.

The inspection must be a structural examination, including non-destructive testing if necessary, of the boom and boom suspension system i.e. any part of the boom and its supporting structures that are subjected to the vibration and shock of driving piles, extracting piles, and compacting. A professional engineer must certify the inspection.
