D. Inspect condition of the body for wear and damage, particularly on
the inside of the jaw opening.
E. Inspect condition of the lifting shackle and shackle screw for wear
and damage. Shackle yoke must pivot freely about the shackle
screw. Shackle eye must rotate freely about the shackle yoke.
F. Remove from service any clamp in need of repair.
Step 4.
The clamp is a component of the rigging used in the lifting and trans-
porting of members. It is important to use safe and adequate rigging.
WARNING: Improper or excessively heavy rigging may interfere
with the operation of the clamp and its ability to maintain proper
position on the member. Never attach crane hook directly to the
clamp. Always use a flexible sling between the crane hook and
the clamp.
Step 5.
Position clamp on the member to be lifted. Do not allow inside of the
jaw opening to rest on the member to be lifted. Maintain 1/4” clear-
ance. Refer to Illustration C on the following page.
Position clamp such that the direction of force applied by the crane is
in line with the lifting shackle.
WARNING: On Model RSC never exceed ten degrees side load-
ing.
Refer to Illustrations D and E on the following pages.
WARNING: Do not use clamp unless springs are in place and are
holding the swivel jaw and screw cup at 90 degrees to the length
of the screw.
