7. General Operation Notes
Always use the lifting device corresponding to the
intended use and in proper shape, keep to the maxi-
mum load dimensions and mind their material hard-
ness (also see chart of usage and materials chart). If
applicable, mind the minimum load acc. to the chart
of usage. do no overload the lifting device. [1]
Mind the admissible attachment and inclination angles,
as they may result in a reduction of the carrying capac-
ity given! Also see information on models.
Never engage the lifting device directly to crane hooks
but connect them via a suitable lifting sling. Mind the
carrying capacity of the chain sling. Only use load
hooks / crane hooks with safety catches. [2]
Never transport the load with open safety lock. Never
stop the safety lock functioning. [3]
Attach the lifting device completely and all the way to
the load. Exception: Vertical clamps for lifting and
turning of sheets / girders need a free space of 3 – 5 mm
between stop and load edge as it can hardly or not at
all be loosened after the load has been set down.
Close the locking mechanism. The load must not slip
after lifting. If the load slips, set down the load and
attach anew.
For lateral attachment of the clamps ensure the
inclination angle to be only as large as the gripping
elements are fully engaged to the load and are still far
enough from the load edge.
Only attach lifting clamps to plane parallel surfaces
(no conical surfaces, no circular tubes, no checker or
bulb plates, no perforated plates)! [4]
Do not grab into shear or clamping positions in order
to avoid injuries.
Always attach the lifting devices in the load centre of
gravity. Avoid inclined suspended loads. In case of
inclination, set down the load and re-attach the lifting
device.
Employ the number of lifting devices necessary to
stabilise the load. In order to avoid oscillation for longer
and especially thin loads, we recommend using pairs
of lifting devices in a 2-legged chain sling (Watch out
for inclination angles!) or at a spreader beam. Ensure
an even distribution of loads and an even charge to all
the lifting devices used. For lateral attachment, the lifting
devices are to be engaged at the same opposite height.
The lifting devices employed must all have the same
lifting capacity. [5]
Avoid oscillation, lifting and lowering in jerks as well as
collisions with other loads. Ensure for enough free
space to surrounding obstacles.
Never pull sheets from the bottom of a stack.
Never pull away jammed loads. [6]
Only lift single loads with lifting devices intended for
lifting vertically positioned loads. [7]
Is the clamp intended for lifting sheet stacks, must
these be stacked evenly..
Never transport anything hurriedly. Never stand in the
danger zone. Never lift loads over persons or over
safety areas. Always drive the load slowly, evenly and
without oscillation. [8]
Never open or remove the crane hook safety catch or
the safety lock at the lifting device or take down the
lifting device from the load before the load is in a stable
resting position.
No not leave the loads unattended in the crane hook for
longer periods of time.
It is not allowed to use lifting devices without safety
lock at travelling fork lifters, mobile cranes etc.
WARNING: danger of accident by crash of
the lifting device and/or the load!
Raddled or misused lifting device can lead to
failure and/or slipping, tilting or crash of the
load.
This can lead to death or severe injuries or
damage machines or other equipments.
• Keep to the operating instructions!
• Immediately exchange defect or worn parts
by original spare parts!
