If, during the frequent lift inspection, the operator believes the clamp
exhibits excessively worn parts or is damaged the clamp should be
inspected by a qualified person who will make a determination as to
its fitness to make a lift. At this time the condition of the clamp should
be noted and recorded. After inspection by the qualified person it may
be decided that a periodic inspection procedure is necessary.
Periodic Inspection:
A recorded inspection by a qualified person as described in the Periodic In-
spection Procedure below timed according to the clamps service class.
•
Normal Service
: annual
•
Heavy Service
: semi-annual
•
Severe Service:
quarterly.
If during any inspection a condition is found which leads to a periodic
inspection then the next periodic inspection is due from the time the
clamp is returned to service. See the table below.
Normal Service-One Year
Heavy Service-6 Months
Severe Service-3 Months
Warning: If any hazardous condition is found that may cause injury to the
operator or other personnel then the clamp should be subjected to a Pe-
riodic Inspection by a Qualified Person.
Repair (replacement of worn parts)
During regular maintenance when replacing parts that are worn a re-
cord should be made of the parts replaced. After the replacement of
worn parts clamps need not be load tested.
Repair (replacement of damaged parts)
During a repair in which parts are replaced due to damage a record
should be made of the repair. At this time the clamp should be marked
with the following information as per the ASME B30.20 requirements:
•
Name and address of the repairer
•
Repairer’s unit identification
•
Clamp weight (if altered)
•
Rated load (if altered)
•
ASME BTH-1 Design Category (if altered)
•
ASME BTH-1 Service Class (if altered)
