1. Vertical lift: The lifting
of a vertical plate or
member in which the
lifting force exerted by
the rigging is evenly
distributed and is direct-
ly above and in line with
the clamp's lifting shackle. Ths is illustrated above.
2. Vertical turn/lift: A
vertical turn/lift clamp is
one designed to turn a
single plate or member
from horizontal to vertical
through a 90° arc; or
from horizontal to vertical
to horizontal through a 180° arc.
3. Horizontal lift: Multiple clamps are attached to the
sides of a horizontal plate. The clamps are attached
to a multi-leg sling centered over the plate. Refer to
illustrations.
WARNING:
is based on a sling angle of 60°. See illustration
(right). Sling angles less than 60° increase the
load exerted on the clamps.
WARNING:
clamps are rated in pairs. One
half of the rated capacity is
the maximum allowable load
for one clamp.
4. Finished and polished plates: Steel plates such as
stainless which have other than hot rolled surfaces
are generally handled with non-marring clamps having
at least one smooth gripping surface. Extra caution
is therefore required.
