1 Safety advice
1.1 Advice for the use of the wire rope winches
The wire rope winches are designed to lift and to lower loads vertically in building and mounting trade and for
different transportation tasks.
Every other mode of use is prohibited and undertaken at the risk at of the operator. Refer to the manufacturer in
advance for any special mode of use.
The modern design of the wire rope winch guarantees safety and economic use with a high lifting speed and a high
load capacity. The wire rope winch should preferably be attached to a ceiling but it is also possible to mount these to
walls with a special mounting kit (optional).
The wire rope winch is wear resistant and nearly maintenance free due to the closed oil filled gear box, the surface
hardening of the toothed wheels made from high-strength steel, which are ball bearing supported. A wear resistant
DC-brake ensures safe braking and holding of the load.
Using the wire rope winch to carry people is strictly prohibited!
Before initial operation, ensure that all electrical wires are connected safely, and are undamaged and
that all equipment can be switched off at a main switch.
It is the responsibility of the operator to ensure that all suspension points of the wire rope winch are
calculated to withstand the dynamic forces caused by the lifting equipment. The wire rope winch can
only be operated safely if correctly mounted, maintained and operated.
For use of the wire rope winch in an aggressive environment - please consult the producer.
The following safety advice is issued for both the maintenance and the operation of the wire rope winch and for
most standard uses. It may not necessarily cover all situations. If you are in any doubt, please contact your dealer.
This manual will tell you how to operate the wire rope winch and how to handle its suspension or its loads safely. It
is compulsory to take care of the following safety advice. They may not be complete for each mode of use, please
ask the producer or your local service partner if any question came up.
You should keep this manual clean, complete and in a legible condition.
Neither the manufacturer nor dealer accept responsibility for any damage or lack of functionality due to the
following:
•Carrying out inappropriate operations for a wire rope winch

Caution!
The suspension points have to be calculated to withstand the forces created by the
winch with wall bracket.
Screws M10 according to DIN 933 and strength class 8.8 have to be used. A tightening
torque of 45 Nm is required.
Check that the rope winds properly onto the drum on initial use. If the rope winds onto one side of the
drum only, please check if the winch is fitted absolutely horizontally. In case of loose rope, the rope
has to be wound down and after that wound up, guided by hand, so that it is tight on the drum.
(Attention: Danger of injury - Use safety gloves!). Check that the whole distance covered by the load
is clear of any obstructions.
Check the unloaded hook to see if it moves in the directions shown by the symbols on the buttons of
the control device.
Run the hook carefully up to the upper hook position and check that the electric limit switch is working
properly. After the limit switch has switched off lifting mode, lowering must still be possible. The
electric cables must not be squeezed or pulled.

4.1 Mains connection
Work on the electric installation may only be carried out by qualified electricians.
The mains power supply (main incoming line conductor) must be disconnectable at all poles by means of a mains
switch (in accordance with EN 60204-1 section 5.3).
Check that the mains voltage agrees with that specified on the type plate.
Connect mains current supply lines and control line according to wiring diagram (if the control cable is
not included in the delivery).
The L1, L2, L3 and PE terminals for the mains connection are located in the separate control box.
A cable 4G1.5² (minimum cross section 1.5 mm²) is necessary for the mains connection.
After connecting, press button for lifting. If the load moves downwards, interchange the L1 and L2
supply cores.

4.3.2 Adjustment of the electric limit switch
The load hook switches off the lifting motion by touching the actuator of the limit switch (see Figure 6). The switch
point is pre-set at the factory.
The limit switch should be activated immediately after the hook touches the actuator. The switch cam is adjustable
and attached to the shaft by a small threaded pin.
Figure 7: Winding scheme
4.3.3 Hazardous operations
If the operator doesn’t switch off the lowering motion after the load has reached the ground or the winch is assembled
higher than the length of rope allows, the rope could accidentally be fully released and rewound in the wrong direction.
The direction of motion will no longer comply with the symbols on the buttons.
Further operation of the wire rope winch is prohibited!
Another reason for a wrong direction of motion may be, that the wire rope is trapped between loose windings / layers
of the lower rope windings. In case of wrong motion direction, the load will be lifted despite of the button for lowering
is pressed. If the highest hook position is reached in this case, the limit switch won’t work anymore and this could
cause a rope or winch casing to break and the load to be dropped.
Further operation of the wire rope winch is prohibited!
If the failure in direction motion is recognized during the operation, the rope must be driven back to the start point of
wrong direction winding, the cause of malfunction has to be removed and the operation can be continued in the right
direction.
In case of wrong winding motion, if the hook tackle has touched the limit switch actuator, no further movement up or
down will be possible.
After disconnecting the power supply, the L1 and L2 wires must be interchanged to allow the hook to leave the limit
switch area. The original connection must then be re-established.
The problem which has led to the wrong lifting direction has to be sorted out as above.
The wire rope must be wound up regularly and tightly (Use safety gloves!).
Check, that the wire rope is undamaged.
Caution!
When lowering the hook, it is not permitted to release all rope from the drum. A minimum of four
windings should remain on the drum to avoid winding in the wrong direction.
