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 gripping surfaces for wear and defects. Gripping surfaces
must be smooth and free of foreign matter.
•
Swivel jaws should turn freely. Inspect swivel jaw mount-
ing holes in body for elongation indicating overloading
and wear.
•
The lock spring must have a definite amount of tension
when the lock is moved to the “Lock Closed” position
without material in the clamp.
•
Inspect the condition of the body for wear, damage and
distortion, particularly in the area of the jaw opening.
•
Inspect lifting shackle and all pin holes for wear and dam-
age.
Remove any clamp from service in need of repair.
WARNING: Do not use the clamp if in need of repair.
