Step 4.
The clamp is a component of the rigging used in lifting or transporting
a plate. It is important to use safe and adequate rigging. The lock is
used to hold the clamp in place until the gripping mechanism is actuat-
ed 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.
Step 5.
Move the lock lever to the “Lock Open” position. Gripping cam is main-
tained in retracted position. Refer to illustrations C and D.
