SAFETY INSTRUCTIONS (CONT.)
USING THE UNIVERSAL PLATE CLAMP SAFELY
DON’T FORGET!!
■
Never overload a clamp
(if more than one is used ensure each can
take its share)
■
Never exceed the permitted maximum or
minimum thickness
■
Never use beyond the permitted angles
■
Never use on hard or polished plate unless
designed for that purpose
■
Never try to lift more than one plate
■
Never place packing between the plate and
the jaws
■
Some designs of clamp, particularly
those with a moving cam action jaw
where the initial grip is provided by
a spring, have a minimum load and
minimum plate thickness they can
safely lift. Wherever possible refer to
the manufacturer’s instructions but
in the absence of specific guidance
the load should not be less 10% of the
rated capacity. The minimum plate
thickness should not be less than 20%
of the maximum jaw range. For more
information contact Pacific Hoists
technical support.
■
Some designs of plate clamp are suitable
for lifting plates from the horizontal to the
vertical and the inclusion of a pendant
chain to provide articulation between
the clamp and lifting hook is essential.
However the use of pendant chains
should always be considered to prevent
the hook weight being imposed on the
clamp as this might cause the clamp to
be released.
■
Position the clamp correctly. Place
the clamp over the centre of gravity of
the plate. If the plate is long and has
a tendency to bend, use two clamps
equally disposed about the centre of
gravity in conjunction with a spreader
beam.
■
Take care to ensure no one clamp takes
more than its rated capacity.
■
Ensure the clamp is fully locked or
tightened onto the plate before lifting.
■
Under no circumstances should packing
be placed between the plate and the
jaws nor any attempt made to lift more
than one plate in the clamp.
■
When using the universal type, check
the manufacturer’s instructions for the
limitations on the angles they may be
used at.
