Inspection Schedules

added by Robyn under Inspections

How often must a hoist be inspected?

To keep a hoist operating at peak efficiency, it is necessary to implement a regular inspection program.  This will allow for the replacement of parts that are worn or damaged prior to the hoist becoming unsafe.  The inspection intervals are based upon the type of service and the degree of exposure to wear that may lead to deterioration or malfunction of the hoists critical components.

The type of service to which a hoist is subjected is classified as "normal", "heavy" or "severe.

Normal Service: Involves operation with randomly distributed loads within the rated load limit, or uniform loads less than 65% of rated load for not more than 15% of the time from manual hoists, and 25% of the time for powered hoists.

Heavy Service: Involves operating the hoist within the rated load limit which exceeds normal service.

Severe Service: Normal or heavy service with abnormal operating conditions.

Two classes of inspection; frequent and periodic, must be performed.

Frequent Inspections:  These inspections are visual inspections by the operator or other designated personnel.  Records of these inspections are not required.  The frequent inspections must be performed monthly for normal service, weekly to monthly for heavy service and daily to weekly for severe service.

Periodic Inspections:  These inspections are visual inspections of external conditions by an appointed person.  Records of periodic inspections are to be kept for continuing evaluation of the condition of the hoist.  Periodic inspections are to be conducted yearly for normal service, semi-annually for heavy service and quarterly for severe service.

Any deficiencies found in an inspection must be corrected prior to a hoist being returned to service.  Also, external conditions may show the need to disassemble a hoist for a more detailed examination.
