INSPECTION
All ACI hoists are inspected and tested at the factory. Regular in-service inspection and preventative maintenance
programs not only help reduce overall maintenance costs but may also prevent service shutdowns by forewarning of
problems that could arise and cause a shutdown. Regular inspections, periodic minor adjustments, regular cleaning,
lubrication, and replacement of worn parts can help maintain the hoists performance and operation in good order.
Hoists shall be maintained, inspected and tested in accordance with this manual and in accordance with the intervals
and requirements of ASME B30.16. Cranes shall be maintained, inspected and tested in accordance with the manual
furnished by the crane manufacturer and in accordance with the intervals and requirements of, as applicable, ASME
B30.2, ASME B30.11, or ASME B30.17. The following definitions are from ANSI/ASME B30.16 and pertain to the
inspection procedures below.
•
Designated Person
–
a person selected or assigned as being competent to perform the specific duties to which
he/she is assigned.
•
Qualified Person
–
a person who, by possession of 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 and work.
Definitions of service from ASME B30.16 are as follows:
•
Normal Service
–
service which involves operation of the hoist 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 for a single work shift.

Prior to Maintenance or Inspection
Before maintenance or inspections are performed on a hoist, trolley or crane the following precautions shall be taken as
applicable.
•
The hoist, trolley, or crane to be inspected, tested or repaired shall be run to a location where it will cause the
least interference with other hoists, cranes and operations in the area.
•
If a load is attached to the hoist hook, it shall be landed.
•
All controllers shall be placed in the off position.
•
If the hoist is trolley suspended, the trolley shall be blocked to prevent trolley movement.
•
If the hoist is installed on a crane, the crane shall be blocked to prevent crane movement.
Hazardous voltages are present in the control box, other electrical
components and connections between these components.
The main switch (disconnect) of the hoist, crane or lifting system
shall be de-energized. Lock and tag the main switch in the de-
energized position in accordance with ANSI Z244.1.
