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 jamming
or trapping of the load cannot to be prevented and recogni-
zed and forces thereby occur, which overload the winch.
An overload protection is required starting from a load-car-
rying capacity of 1000 kg or a towing force of 10 kN.
– Winches are provided with an emergency stop function.
GB
– 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.

7. ExAmInATIOn, SERVIcE, mAInTEnAncE

Winches, lifting and towing appliances including their suppor-
ting structure must be examined by an expert:
– Before commissioning.
– After substantial modifications before recommissioning
– At least once annually.
– If unusual events have taken place, which could have a
damaging effect on the safety of the winch (extraordinary
examination, e.g. after longer disuse, accidents, natural
occurences).
– After repairs, which could affect the safety of the winch.

6. OPERATIOn

The safety instructions specified in Chapter 2 apply.
– Always work with the consideration of safety and risks.
– Never overload the winches
– When changing the rotation direction of the motor wait until
it has come to a standstill.
– Observe duty cycle (type plate, technical data in Chapter 3.3).
For example 40% ED (according to VDE 0530) means,
that the motor can operate for 4 minutes during a period
of 10 minutes. It is thereby irrelevant how heavy the load is
and whether the 4 minutes are consecutive or in intervals.
S2-12 min. means that the motor can run continuously for
12 minutes, afterwards however must cool down to the
ambient temperature.
– The load must be safely suspended in the load carrying
equipment and both must be safely hooked into the load
hook and be located on the base of the hook. The safety
catch of the hook must be closed.
– Always initiate load movement with lowest speed. First
tension the rope, it may not be slack at the beginning of the
load movement.
– Continuously observe load during the movement.
– Pay attention to rope damages. Immediately report defects
to the responsible person. First repair defects, then conti-
nue working.
– Carry out required examinations and observe maintenance
intervals.

Operation of the options see Chapter 8
A person is an expert, who due to his professional training and
experience has sufficient knowledge in the area of winches,
lifting and towing appliances and is familiar with the relevant
national industrial safety and accident prevention regulations
as well as with the general rules of technology (laws, stan-
dards, technical rules and regulations) in such a way, that he
can assess the safe operating condition of the device.
