3 Product description
The lifting clamp consists of a sturdy steel construction that is capable of safely lifting the load
(panels, plates) by means of a form-locking clamping jaw.
The required contact force is generated by the own weight of the load via a lever mechanism with
chain sling. The contact force of the clamping jaws depends on the own weight of the load. Different
load thicknesses can be adjusted by means of a perforated grid on the lifting clamp.
A deviation of thickness (<10 mm) of the load is compensated for by the lever of the lifting clamp. A
tension spring provides the necessary retention force for the lifting clamp to be held without
load.

5 Safety
5.1 Intended use
The lifting clamp is intended for the lifting, lowering
and moving of individual so-called self-supporting
sandwich elements with rigid polyurethane foam
core (manufactured to DIN EN 14509:2013-12) in
the context of the conditions listed in chapter 9,
Technical data, with operation by one person.
Any use going beyond the above is considered
contrary to intended use.
Use in a potentially explosive atmosphere is
prohibited.
Any
- alterations or extensions
- use of non-original spare parts
- repairs carried out by companies or individuals that are not authorized by the manufacturer
may result in loss of warranty, unless specifically approved by the manufacturer in writing.
5.2 Selection and qualification of staff
Staff that operate or install the lifting clamp must
- be at least 18 years old.

- be adequately trained for the respective tasks.
- know and observe the relevant technical rules and safety regulations.
The operating company decides upon the required qualifications for the
- operating staff
- service staff
- maintenance staff
The operating company must ensure that only authorized staff will perform any task on the lifting
clamp.
Staff that are to be trained, taught, instructed or placed in an apprenticeship may only work on the
lifting clamp under constant supervision of an experienced person.
Work on electrical and pneumatic components must only be performed by qualified staff with
appropriate training and in compliance with all applicable rules in the accident prevention regulations
(UVV).
5.3 Dangers arising from the lifting clamp
The operating company must ensure that the operator has been adequately instructed regarding
potential dangers, and will comply with these instructions.
5.3.1 General dangers arising from crane operation
If a crane that carries a load by means of a lifting clamp is operated incorrectly (pulling at angles, load
swing, excessive weight, attaching the load in an unsafe or unbalanced way, sudden change of load
direction, etc.) it may topple or be damaged. This might result in personal injury and/or material
damage. Before the lifting clamp is put into operation, the safety regulations for the crane must be
read, understood and observed.
5.3.2 Danger due to the weight of the lifting clamp
The lifting clamp is heavy. If it falls, this may result in personal injury and/or material damage.
Operators must wear personal protective equipment adequate to the circumstances (gloves, head
protection, protective footwear, etc.).
5.3.3 Danger due to the load slipping out
If one or both clamping jaws are damaged or soiled, this might reduce the friction at the clamping
jaws that is necessary for safe operation. As a result, the contact force required for lifting the load
might be reduced to the extent that the load cannot be held safely anymore, and the load might slip
out. A falling load might cause personal injury and/or material damage.
Both clamping jaws must be clean and undamaged.
5.3.4 Danger due to wrong clamping jaws
Unless the lifting clamp is operated with at least one form-locking clamping jaw, the load can no
longer be held safely in case of an inadvertent loss of friction. A falling load might cause personal
injury and/or material damage.
The clamping jaws must be installed according to the load and in correct position (see 7.1).

Version 1.3 9 / 24
5.3.5 Danger of being crushed by moving parts
As a result of the tension on the chain (1) and the
movement of the lever (at the grip G) there is a risk of
being crushed between the parts in the marked areas (X)
(e.g. for fingers, hands, ball of the thumb, etc.).
Do not reach into the marked areas (X).
Do not touch the lifting clamp while it is being closed (the
chain (1) is being pulled in the direction of the arrow).
Only touch the lifting clamp at the grip (G) while the load
is being conveyed.
Do not touch the chain when the lifting clamp is opened
as it will be drawn into the housing.

5.4 Safety devices
The operating company must ensure that trained staff will
- regularly check all safety devices.
- immediately rectify any detected faults on safety devices.
- secure the lifting clamp against being put into operation unless all safety devices are in place and
fully functional.
