Maintenance Program for Renfroe Clamps Manufactured from Steel
The severity of service to which the clamp is subjected in the work place
determines 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 minimum inspection requirements for “Below-the-
Hook” lifting devices and the Renfroe Recommended Inspection Sched-
ule meets and/or exceeds the ASME inspection recommendations.
Before using a clamp operators should be trained by a qualified per-
son to visually inspect a lifting clamp that will include but not be lim-
ited 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
warning 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 sur-
faces must be sharp and free of foreign matter.
•
Inspect condition of body for wear, damage and distortion,
particularly in the area of the jaw opening.
•
Inspect lifting shackle and all pin holes for wear and damage.
•
Lock spring must have a definite amount of tension when lock
is moved to the “Lock Closed” position without material in
the clamp.
•
Remove any clamp from service in need of repair.
