The rope coiling direction is correct, if:
A) Right-handed rope = left-handed drum = standard
= Required with grooved drum
B) Left-handed rope = right-handed drum = exception

Rotation direction of
the drum: right

B
The rope direction is correct, if:
The deflection pulleys are arranged centrically to the drum at a
minimum distance. Largest rope deflection angle for non-twist-
free rope < 2°, for low-twist rope < 4°.
β = Rope deflection angle at the roller
β-α or β+α = Rope deflection angle at the drum
α = Angle of the drum grooves
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:
– 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.

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 fulfil these requirements.

Observe safety notes in Chapter 2.
z Have an expert check the devices before commissio-
ning (Qualified person, Chapter 7).
z Carry out the examination according to the supplied
test book and following the specifications 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.
Connecting electrical rope winches by means of
power plugs is not permissible according to Din En
60204-32.
– 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 contactors
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 difference at the supply terminals of
the rope winch max. ± 5 %. Observe power supply specifica-
tions in the circuit diagram.
z Interrupt the brake coil supply during lifting operation and
when pulling loads on inclined services on the direct current
side (= faster response of the brake).
This is already available in the case of factory installation of
the control unit.

5.2 minimum requirements

Rope winches must correspond to the requirements of the
valid international and national standards and guidelines.
It is required in particular that:
– Winches are equipped with lifting and lowering limiters
(Limit switches).
– Rope intake positions in the work area of the operating
personnel and in the traffic area are safeguarded.
– Winches are equipped with overload protection, if jam-
ming or trapping of the load cannot to be prevented and
recognized and forces thereby occur, which overload the
winch. An overload protection is required starting from a
load-carrying capacity of 1000 kg or a towing force of 10
kN.
– Winches are provided with an emergency stop function.
– Control equipment for initiating and stopping the move-
ment are equipped with an automatic reset.
– Control equipment for lifting (reeling the rope) and lowering
(unreeling the rope) is available and reciprocally locked.
– Slack rope formation does not cause in the endangering
conditions.
– The load carrying capacity is clearly recognizable for the
user.

5.3 Options

haacon mounts the limit switches for options. All switches are
connected, wired and checked, if the control unit has been as-
sembled in the factory. Fine adjustments must be carried out
on-site according to the operating conditions (Chapter 8).
In all other cases, the operator is responsible for wiring the
options correctly.
