1 General
Congratulations with the acquisition of a Gunnebo Lifting safety plate lifting clamp.The quality
systems of management and services of Gunnebo Lifting fully comply with ISO 9001
standards. The many years of vast experience are a guarantee of optimum quality and safety.
Gunnebo Lifting Clamps are made of top quality steel and fully comply with European standards
as laid down in Machine Directive 2006/42/EG.
2 Operating Principle
The CH, CHE, CHS, CHNM and CHP horizontal safety lifting clamps have specifi cally
been designed for the horizontal lifting and transporting of non-bending steel plates. The
clamps consist of a body, cam, and cam pin. The cam also functions as a lifting shackle and
ensures that the load is held fi rm-ly while it is being lifted.
3 Permitted Applications
CH, CHE, CHS and CHNM
Gunnebo Lifting CH, CHE and CHNM lifting clamps are only suitable for lifting and horizontal
movement of non-bending steel plates and structures where it is possible to position the clamp
on a fl at point of contact. The clamps should always be used in pairs, or multiples thereof.
In the latter case, however, preferably with a load spreader beam.
CHD
Gunnebo Lifting CHD lifting clamps are only suitable for lifting and horizontal movement of both
bending steel plates and formed steel plates, where it is possible to position the clamp on
a fl at point of contact. CHD clamps should always be used in pairs, or multiples thereof.
CHP
Gunnebo Lifting CHP clamps are only suitable for horizontal movement of steel plates and packages
of steel plates, where it is possible to position the clamp on a fl at point of contact. The clamps should
always be used in pairs, or multiples thereof. In the latter case, however, preferably with a load
equalising beam. Provided that the steel plate of plates do net bend (defl ect), one or more plates can
be hoisted at once per Iift. When pairs or multiple clamps are used, each damp should carry en
equal part of the load.

4 Safety Instructions
Safety fi rst! Guarantee your personal safety by carefully reading the following safety
instructions fi rst.
Ensure your own safety and continue to benefi t from our product safety by having the
clamp inspected, tested and, if necessary, overhauled at least once a year by Gunnebo Lifting
or a recognized mechanical repair and service centre. See also Chapter 8 - Overhauling.
Contact Gunnebo Lifting for further information.
Avoid situations dangerous to life
Prevent dangerous situations by seriously taking care of the following precautions:
- Never work with an untested clamp.
- Keep your distance when lifting and never stand under the load.
- Do not use the clamp if (it has been) damaged; have the clamp immediately repaired by Gunnebo
Lifting or a recognized mechanical repair centre. If in doubt consult your supplier.
- Never lift more than one plate or a package of plates at a time.
- Never lift plates heavier than the working load limit (W.L.L.), as indicated on the clamp and in the
test certifi cate.
- Do not lift plates which are thicker or thinner than the jaw opening, as indicated on the clamp and
in the test certifi cate.
- When using a number of lifting damps at the same time, please provide lifting slings or chains of
a suffi cient length to ensure that the angle between the slings or chains never exceeds 60°.
- When simultaneously operating a number of lifting clamps time side by side, please use a lifting
beam (equalizer) and lifting slings or chains of a suffi cient length to ensure that the lifting shackles
on the clamps are never subjected to lateral load.
- Do not place the clamp on tapered or conical sections of the plate or structure to be lifted.
- Remove all grease, oil, dirt, corrosion and mill scale from the plate at the point where the clamp is
to be attached.
- Ensure that the damp(s) is (are) positioned so as to balance the load when it is being lifted.
- The surface hardness of the plate must not exceed 37 HrC (345 Hb, 1166 N/mm2).
- The clamp is only suitable for use in normal atmospheric conditions.
Safety precautions
Ensure that the cam can never be subjected to lateral load.
- A free fall or uncontrolled swaying at the crane hook resulting in objects being struck, may cause
impact damage to the clamp. If this happens check whether the clamp is still in good working
order before using it.
- Lifting clamps are not suitable for creating permanent joints.
- Maintenance of the clamp should take place on a regular monthly basis, see Chapter 6 - Maintenance.
- Do not modify the clamp (by welding, grinding, etc.), as this can adversely affect its operation and
safety, thereby nullifying any forms of guarantee and product liability.
- For the very same reason, use only original Gunnebo Lifting components.
- Any improper use of the clamp and/or failure to observe any directions and warnings in these
operating instructions concerning the use of this product may endanger the health of the user
and/or bystanders.
The following additional safety precautions are applicable to the CH, CHE CHS, CHNM
CHD and CHP model
The clamps can be loaded laterally at a maximum angle of 15°, only when they are not loaded
more than the maximum W.L.L. and the permitted top angle. The capacity of the clamps has been
calculated on basis of a maximum top angle of 60°. In case of situations with larger top angles, then
5
the WL.L. should be reduced proportionally, according the following loading drawing.
With shored up usage, a maximum top angle of 60° is applicable and the W.L.L. is 50% of
the maxi-mum permissible working Ioad. The environmental temperature for use of the
standard lifting clamps is between minus 40 and 100 °C.
The clamps can be loaded laterally at a maximum angle of 15’.
5a Lifting with CH, CHE, CHS, CHD and CHNM Clamps
- Check whether the working load limit (W.L.L.) of the clamp is suffi cient for the load created in the
lifting situation. Note: The working load limit (W.L.L.) is shown on the lifting clamp.
- Attach the lifting clamp to the hoisting mechanism either by means of a:
- Safety shackle directly to a crane hook,
- Coupling link or D-shackle,
- Sling or chain, if necessary in conjunction with a coupling link or D-shackle.
- Ensure that all attachments have been tested and are of the correct tonnage. Make sure that coupling
links and shackles are large enough to allow the clamp to move freely in the hook.
- Check whether the clamp has any visible damage. Check whether the cam opens and closes
smoothly.
- Check whether the teeth of the cam are free from dirt, and if necessary clean with a wire brush.
- Remove any grease, dirt and mill scale from the plate at the site of the lifting clamp.
- Open the clamp.
- Place the jaws as far as they will go over the plate, making sure that the clamp is positioned so as to
balance the load when it is being lifted.
- Lift gently so that the lifting force can be applied; check whether the clamp is rotating or tilting.
- If the clamp is rotating or tilting read the fore mentioned remarks on lifting again.
- Ensure that the load is in a stable position.
5b Lifting with CHP Clamps
- Place the clamp onto the plate (cable or chain already attached to the tooth segment; and take care
that the chain of cable is not twisted);
- Tighten the clamps fi rmly by hand;
English
6
- Tension the cables or chains with the crane hook, while the inside of the jaws presses fi rmy against
the edge of the plate (note: due to the fact that the clamp does not have a con-stant pre-tension
available on the tooth segment, it will be necessary to watch the position of the clamps until the
cables are tensioned: make sure the clamps stay in the correct posi-tion).
- The load can now be lifted carefully.
- During the transport of the load, take care that a constant tension is maintained on chains or slings.
- To unhook, the crane hook should be lowered so far that the clamp is completely free of any load
(note: make sure that when the load is lowered, there are no obstacles underneath where the load
could rest on during lowering and whereby the clamps will become unloaded to early by accident).
- The clamps can now be removed from the load.
6 Maintenance
- Check the general condition of the clamp at least once a month, see Chapter 7 - Disassembling/
Assembling.
- Do not use the clamp if:
- the body is split or deformed, in particular in way of the jaw corners,
- the cam has been visibly deformed,
- the cam teeth are no longer sharp,
- the shackle pins have visibly been deformed,
- any retaining pins are missing,
- the marking on the clamp is no longer legible.
Depending on the defects noted:
Disassemble and clean the clamp (see Chapter 7 - Disassembling/Assembling) or have the
clamp overhauled by Gunnebo Lifting or another recognized mechanical repair
center (see Chapter 8 - Overhauling).
