DEFINITIONS
VERTICAL LIFT:
The lifting of a vertical plate or
member in which the lifting force exerted by the
rigging is evenly distributed and is directly above
and in line with the clamp’s lifting shackle. This is
illustrated in (Fig. 1).
VERTICAL TURN/LIFT: Turns a single plate or mem-
ber from horizontal to vertical through a 90° arc, and
back to vertical through the same 90° arc; or from
horizontal to vertical to horizontal through 180° arc
(Fig. 2).
HORIZONTAL LIFT: Multiple clamps
are attached to the sides of a horizontal
plate. The clamps are attached to a multi-
leg sling or spreader bar centered over
the plate (Fig. 3).
FINISHED OR POLISHED PLATES:
Steel plates such as stainless steel
which have other than hot-rolled
surfaces are generally handled with
a non-marring clamp that has at least
one smooth gripping surface.
STRUCTURAL MEMBERS AND
FABRICATED SECTIONS:
Unless other-
wise specified, clamps recommended
for structural members or fabricated
sections are limited to steel products
with a hardness not greater than 400
Brinell (43 Rockwell C). For other appli-
cations contact your Campbell

for lifting recommendations.
WARNING!: The capacity of all horizontal clamps is based on a sling angle
of 60°. Sling angles less than 60° increase the load exerted on the clamps.
