NEVER!
6.
DO
place the pad side (short leg) of the clamp under the
plate when lifting from horizontal to vertical position with
clamps other than GX or GXL models (Fig. 9).
7.
DO NOT
use a clamp that needs repair. Inspect the
clamp prior to each lift. Refer to the Clamp Maintenance
and Inspection section of this manual for detailed
instructions .
8.
DO NOT
lift a plate or member whose hardness is greater
than 400 Brinell (43 Rockwell C) with any clamp other than
a non-marring clamp.
9.
DO NOT
attach a clamp to an oily surface or any surface
other than a clean, dry surface.
10.
DO NOT
lift more than one plate at a time (Fig. 10), except
with horizontal clamps.
11.
DO NOT
lift tapered beams or members other than ordi-
nary structural steel.
12.
DO
use as many clamps as necessary to balance the
load (Fig. 11). Do not try to lift unbalanced loads.
13.
DO
use two or more clamps whenever possible.
14.
DO NOT
exceed the combined WLL of two clamps
when using two or more clamps (Fig. 11).
15.
DO NOT
attach a clamp directly to the crane hook. Use
a sling between the crane hook and the clamps to
minimize interference in clamp operation and its ability
to stay in the right place on the plate.
16.
DO NOT
stand near the load when lifting. The operator
should stand clear of the load and should never lift over
people or machinery (Fig. 14).
17.
DO NOT
misuse a clamp. Never lift a plate from the
bottom of a stack (Fig. 12).

DO NOT
rush. Lift slowly and smoothly.
