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 actuated 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
sling between crane hook and clamp.
