FEATURES
FEATURES OF THE GLOBAL PLATE CLAMPS INCLUDE THE FOLLOWING:
■The Global Plate Clamps are manufactured to comply with AS4991.
■Designed for the lifting and transferring of steel plates and other materials in a wide variety of
industries such as; shipbuilding, construction, aircraft and offshore applications.
■The Global vertical and horizontal plate clamps are suitable for the lifting and transfer in vertical
and horizontal position of non-sagging steel plates.
■These plate clamps are manufactured from high quality steel to guarantee the safety and
durability required by industrial applications.
■All clamps have been ergonomically designed to be user-friendly (smaller, lighter and more
compact) while not sacrificing strength and durability.

SAFETY INSTRUCTIONS
■Store and handle beam clamps correctly
■Inspect beam clamps and accessories
before use and before placing into storage
■Ensure the supporting structure is adequate
for the full load that will be imposed and
suitable for the application.
■Check the clamp is of the correct profile
and size, or correctly adjusted, for the beam
width and that it seats correctly on the
beam flange.
■Ensure the beam clamp is strong enough for
the full load that will be imposed.
■Check that the clamp is directly over the
centre of gravity of the load.
GENERAL SAFETY INSTRUCTIONS
■Check the clamp before use – do not use a
defective plate clamp.
■Ensure that the clamps are suitable for the
thickness of plate to be lifted.
■Never exceed the maximum or minimum
thickness for which the clamps are
designed.
■Put the clamp onto the plate as far as it will go.
■Do not use clamps at an angle to the edge
of the plate or for lowering from vertical to
horizontal, or vice-versa, unless they are
designed for the purpose.
■Keep oil, grease and similar contaminates
away from jaws which use a friction grip
material to hold the plate.
■Never use plate clamps on hard or polished
plate unless they have been specifically
designed for that purpose.
■Take great care to ensure the plate is fully
supported before attempting to release the
clamp.
■Keep all persons clear of the danger zone
and remember that a falling plate can ‘glide’
sideways. A large thin plate is likely to glide
further. Also the higher it falls from, the
bigger the danger zone.
THE FOLLOWING SAFETY INSTRUCTIONS OUTLINE THE CARE AND SAFE USE OF UNIVERSAL
AND HORIZONTAL PLATE CLAMPS AND ARE BASED ON SECTION 22 OF THE LEEA CODE OF
PRACTICE FOR THE SAFE USE OF LIFTING EQUIPMENT.
This information is of a general nature; only covering the main points for the safe use of plate
clamps. It may be necessary to supplement this information for specific applications.

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.

SAFETY INSTRUCTIONS (CONT.)
■Always use horizontal plate clamps in
pairs with the correct type, size and
length sling and reeved in the manner for
which they are designed. Some of these
clamps are designed to be used with an
endless loop of chain whilst others are
for use with a two leg sling. Under no
circumstances must an endless loop be
substituted for a two leg sling or vice
versa as this will alter the geometry and
therefore the gripping forces on which the
clamps rely for their safe operation.
■If the plates are likely to sag transversely,
clamps which grip the plate by a cam
must be used.
■Position the clamps correctly. Place
the clamps over the centre of gravity of
the plate. If the plate is long and has a
tendency to bend use two or more pairs
of clamps in conjunction with a spreader
beam, equally disposed about the centre
of gravity, to minimise the sag. Ensure the
clamps face each other to balance the
horizontal clamping forces.
■Take care to ensure no one clamp takes
more than its rated capacity.
■Put the clamps onto the plate as far as
they will go.
■If the sling is adjustable to accommodate
various widths of plate ensure it is
adjusted to give the correct geometry
■Never attempt to rotate from the
horizontal to the vertical or vice versa
with this type of clamp.
DON’T FORGET!!
■Never overload a plate clamp
■Never use a single clamp – always in
pairs
■Never exceed the permitted maximum
or minimum thickness
■Never substitute an endless loop for a
two-leg sling or vice versa
■Never exceed the permitted range of
sling leg angles
■Never use the cam-less type if the
plate can sag
■Never attempt to rotate from the
horizontal to the vertical with this
type of clamp

SERVICE & MAINTENANCE
IN-SERVICE INSPECTION
MAINTENANCE
Plate clamps should be cleaned and any moving parts lubricated at appropriate intervals, unless
the suppliers specific instructions indicate otherwise. In the case of clamps with smooth jaws
lined with a friction material, care must be taken to ensure no lubricant comes into contact with
the friction material.
WARNING: Teeth of jaws must not be re-sharpened or re-cut unless this has been specifically
approved by the maker.
Regularly inspect the plate clamp. If any of the following defects are found, refer to a Competent
Person:
■Wear, damage or distortion to fixed and
moving jaws.
■Frame opening out or cracked.
■Insecure, worn or bent pins, bolts etc
■Worn friction grip material.
■Damaged, bent or unsatisfactory action
locking lever.
■Tight, bent or damaged clamping threads
etc.
■Corrosion.
■Illegible marking

OPERATING INSTRUCTIONS
■Commence to open the plate clamp by
pulling the latch lever towards the jaw
■Continue to place the plate clamp
securely to the to-be lifted material and
make sure that the jaw of the place clamp
rests on the material.
■The plate clamp will close by pulling
the latch lever towards to lifting eye.
The clamp will now stay attached to the
to-be lifted material in the pretensioned
position.
■The lifting application can begin.
■After the lifting application is completed,
make sure the clamp is fully free of load
by decending the crane hook. The lifting
eye of the plate clamp can now move
freely and you are able to open the clamp
by pulling the latch lever towards to jaw.
■When storing the plate clamp, please
leave the clamp in an opened position.
This position will protect the teeth from
damaging.
