Step 3.
Inspect clamp before each lift.
WARNING: Do not use if in need of repair. If in doubt, refer to
Maintenance Section for detailed maintenance instructions and ex-
ploded view of the clamp for part identification.
A. Check the clamp to be certain the Identification and warning
tags are present and legible.
B. Do not use the clamp if the tags are missing or illegible
C. Inspect gripping surfaces for wear and defects. Gripping surfaces
must be sharp and free of foreign matter.
D. Inspect condition of body for wear, damage and distortion, particu-
larly in the area of the jaw opening.
E. Inspect lifting shackle and all pin holes for wear and damage.
F. Lock spring must have a definite amount of tension when lock is
moved to the “Lock Closed” position without material in the clamp.
G. Remove any clamp from service in need of repair.
Step 4.
A clamp is a component of the rigging used in lifting or transporting a
member. It is important to use safe and adequate rigging. The lock is
used to hold the clamp in place until the gripping mechanism is actu-
ated by a force applied to the lifting shackle.
WARNING: Improper or excessively heavy rigging may interfere
with the operation of the clamp and its ability to maintain a proper
position on the plate. Never attach crane hook directly to the
clamp - always use a flexible sling between crane hook and clamp.
