Model SCP/A Periodic Inspections
Step 1.
Verify the identity of the clamp by checking the I. D. plate on the clamp
body. If the I. D. plate is missing or not legible an RFID chip (Radio
Frequency Identification Device) is embedded in the clamp body or a
clamp component. If the I. D. plate is missing and the RFID chip is un-
available call the Renfroe factory for instructions on returning the
clamp for recertification.
Step 2.
Completely disassemble clamp.
Step 3.
Remove all dirt, grease and other matter that may inhibit proper inspection of
the clamp body or clamp components.
Step 4. BODY
A.
Inspect welds for fractures. RENFROE recommends a dye pene-
trant or similar method of detecting indications on the clamp. If an
indication is found it may be necessary to use a magnetic particle,
ultrasonic or similar methods for determining damage to the clamp
or components.
B. Inspect inside surfaces of body side-plates that come in contact with
shackle and shackle yoke for wear and damage.
C. Inspect all pin holes for wear and elongation.
D. Inspect inside of jaw opening for displaced metal and distortion. Refer to
exploded view.
WARNING: Replace clamps containing fractures, elongated holes, dis-
torted jaw opening, distorted and worn threads and jaw openings, with
displaced metal.
Step 5.
SCREW SCP-1
A. Inspect for distortion, damaged threads and wear.
B. Inspect for fractures, particularly in the area in which the screw cup
mounts and on opposite end where holes are provided for spud wrench or
bar.
C. Inspect set screw and threaded hole for damage and distortion.
