8. INSPECTION:
A. GENERAL:
The inspection procedure is based on ANSI/ASME B30.16. The following definitions are from ANSI/
ASME B30.16 and pertain to the inspection procedure below.
1.
Qualified Person: A person who, by possession of a recognized degree or certificate of
professional standing, or who, by extensive knowledge, training and experience has successfully
demonstrated the ability to solve or resolve problems relating to the subject matter at work.
2.
Designated Person: A person assigned or selected as being competent to perform the specific
duties to which he/she is assigned.
3.
Normal Service: A distributed service which involves operation with randomly distributed loads within
the rated load limit or uniform loads less than 65% of rated load for not more than 25% of the time.
4.
Heavy Service: A service which involves operation within the rated load limit which exceeds
normal service.
5.
Severe Service: A service which involves normal or heavy service with abnormal operating conditions.
B. INSPECTION METHODS AND CRITERIA:
This section covers the inspection of specific items. The list of items in this section is based on those
listed in ANSI/ASME B30.16 for the Frequent and Periodic Inspection. In accordance with ANSI/ASME
B30 volumes listed under the General heading on the previous pages, these inspections are not intended
to involve disassembly of the hoist. Rather, disassembly for further inspection would be required if
frequent or periodic inspection results so indicate. Such disassembly and further inspection should only
be performed by a certified or qualified person trained in the disassembly and re-assembly of the hoist.
