The rope direction is correct, if:
The defl ection pulleys are arranged centrically to the drum at a
minimum distance. Largest rope defl ection angle for non-twist-
free rope < 4°, for low-twist rope < 2°.
GB
β = Rope defl ection angle at the roller
β-α or β+α = Rope defl ection angle at the drum
α = Angle of the drum grooves
With grooved drums, the angle α must be included in the cal-
culation!
Measurement (centre drum to centre roller) for standard rope
winches.

Rule of thumb
4.3.4 Rope End connections
Permissible according to EN 14492-1/2:
– Asymmetrical rope locks, which correspond to EN 13411-6.
– Symmetrical rope locks, corresponding to EN 13411-7 with
rope diameter < 8 mm.
– Metal and synthetic resin socketing, which correspond to
EN 13411-4.
– Ferruling and grouting according to EN 13411-3.
Do not use wire rope clamps according to EN 13411-5 for rope
end connections.
4.4 load Hooks
Load hooks are permissible according to DIN 15400 or UNI 9465.
Unintentional loosening of the load must be prevented.
Hooks with a safety catch fulfi l these requirements.
5. cOmmISSIOnInG
Observe safety notes in Chapter 2.
z Have an expert check the devices before commissio-
ning (Qualifi ed person, Chapter 7).
z Carry out the examination according to the supplied
test book and following the specifi cations of the
operating instructions (chapter 7) and document the
results in the test book.
5.1 Power Supply
Observe safety notes in Chapter 2.6.
According to DIn En 60204-32 it is not permitted
to connect electrical rope winches via mains plugs.
– In the case of rope winch controllers with electronic compo-
nents (e.g. frequency-controlled drives), the connection to
electrical circuits with type A residual current devices (RCD)
is not permitted. In such cases, a type B AC/DC RCD should
be used.

– Connection of the power supply to the designated parts L1/
L2/L3/N/PE in the terminal and/or switchbox. –> Connec-
tion and/or circuit diagram. In addition:
z Introduce cables via cable connections, connect protective
conductor correctly.
z Provide the strands with end sleeves.
z Safeguard supply with 1 and/or 3-pole line safety switch
with the characteristic B or C. The rated current of the con-
tactors may not exceed the value of 10 A, in order to prevent
fusing of the contactors in case of a short-circuit.
– Use contactor, supply cable with main switch, emergency
stop with lock. The main switch must be freely accessible
for maintenance staff .
– Power supply according to the Standards DIN IEC 60038
and DIN EN 50160. Voltage diff erence at the supply termi-
nals of the rope winch max. ± 5 %. Observe power supply
specifi cations in the circuit diagram.
z Interrupt the brake coil supply during lifting operation
and when pulling loads on inclined services on the di-
rect current side (= faster response of the brake).
This is already available in the case of factory installation of
the control unit.
