10. Never alter a clamp. Clamp manufacturer's specifi-
cations include specific materials and manufacturing
procedures. Never grind, weld or in any way alter clamp,
as this could cause severe damage or failure.
11. Do not misuse a clamp.
Never lift a plate from
the bottom of a stack.
Never lift horizontally
using a vertical lifting
clamp. Do not improvise.
12. Never attach a clamp directly to the crane hook.
Use a sling between the crane hook and clamp to
minimize interference in clamp operation and its
ability to maintain a proper position in the plate.
13. Never tamper with the locking mechanism of a
locking clamp while making a lift. Always use in "lock
closed" position.
14. Always place pad side (short leg) of clamp under
plate when turning plates from horizontal to vertical
with clamps other than the "GX" models.
15. Know the type of material to be moved before
making lift. Some exotic steels are too hard to
allow teeth of cam to penetrate. This may also be true
of structural members and fabricated sections. If
plates hardness exceeds 400 Brinell, use a
non-marring clamp only.
16. Do not lift plates that are coated with any
substance such as plastic, paint or greese that would
interfere with the cam and/or pad teeth obtaining a
good grip on the plate.
17. Do not lift tapered beams or members other than
ordinary structural steel.
NEVER!
