Maintenance Program for Renfroe Clamps Manufactured from Steel
The severity of service to which the clamp is subjected in the work place deter-
mines the frequency and type of inspection procedure required for the clamp.
The frequency and type of inspection is determined by the clamp owner.
Renfroe acknowledges the ASME B30.20 safety standard which sets forth mini-
mum inspection requirements for “Below-the-Hook” lifting devices and the
Renfroe Recommended Inspection Schedule meets and/or exceeds the ASME
inspection recommendations.
Before using a clamp operators should be trained by a qualified person to
visually inspect a lifting clamp that will include but not be limited to the
following:
Every lift Inspection:
A visual inspection by the operator before and after each lift made by the clamp.
•
Check the clamp to be certain the Identification and warn-
ing tags are present and legible.
•
Do not use the clamp if the tags are missing or illegible
•
Inspect master link and link chain legs for wear and damage.
•
Inspect circular body of clamp for wear, distortion and damage.
•
Inspect lock handle mechanism for wear, distortion or damage.
Remove any clamp from service in need of repair.
WARNING: Do not use the clamp if in need of repair.
If, during the every lift inspection, the operator believes the clamp ex-
hibits excessively worn parts or is damaged, the clamp should be in-
spected 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.
Frequent Inspection:
A visual inspection (see every lift inspection) by an operator or other desig-
nated person timed according to the clamps service class.
