7.4 Determination of the Service life consumption

The theoretical service life ("D") of the haacon rope winches is
according to motor group:
Motor group
D [h]
After expiry of D, the winch must be taken out of service
and forwarded to the manufacturer for a general over-
haul. The operator must determine the consumption of this
service life annually and document this on the appropriate
forms in the test book.
Calculation basis --> European Standard FEM 9.755

7.5 Examination Rope

GB
The rope examination is essentially a visual examination. The
rope must be examined before each shift for outer damages,
deformations, incipient cracks, and corrosion. The rope must
be examined by an expert at least once annually. Notes on
appropriate accomplishment can be inferred from the DIN
ISO 4309 „Cranes - wire ropes - maintenance and servicing,
inspection and storage", as well as EN 12385 1-4 Steel wire
ropes - Safety.
The following must be examined among others according to
these criteria:
– Type, number, and position of wire breaks
– Temporal sequence of wire break formation
– Decrease of the rope diameter
– Corrosion
– Abrasion
– Deformations
– Effect of heat
– Resting time
– Rope attachment
Immediately report defects to the responsible person.
First repair defects, then continue working.
z Immediately replace rope, if a strand has broken (use
original spare part).

7.6 Examination load Hook

The examination of the load hook is essentially a visual exami-
nation.
Before each shift, check the hook for outer damage, incipient
cracks, wear, expansion, corrosion, and functionality of the
safety catch of the hook.
Immediately report defects to the responsible person.
First repair defects, then continue working. Only use
original spare parts.
7.7 Brake motor
– Keep cooling air paths clean.
– Always examine the function of motor and brake before
beginning work.
– Check gaskets and power input in certain time intervals.
(Compare to power input on the type plate).
– Examine the air gap of the brake at least once annually and
reset if necessary.
Observe safety instructions Chapter 2.5 and 2.6.
Only carry out maintenance when disconnected from the
mains supply.

ter Maintenance or Service. Motor allocation to the individual
winch series --> Spare parts lists.

7.8 Gear

Load-carrying capacity < 600 kg oil filling, life-long lubrication.
Load-carrying capacity > 600 kg oil filling, check oil level
annually.
Check gaskets of the outlet shafts annually.
An oil change is theoretical not required during the service life.

7.9 Start-up phase

The start-up phase of the gear unit and spindle generally lasts
2 to 4 operating hours.
The torque can be up to 50% (type ESG/ESF) higher than it is
after the start-up phase.
If necessary, recalibrate the overload protection.

8. OPTIOnS

Some of the available equipment variations (options) are legal-
ly required.

8.1 limit switch

Consisting of limit switch and mounting set. The limit switch
counts the rotations of the drum. It contains two switching ele-
ments for limiting the upper and lower end position.
An end stop is required according to DIN EN 14492-1/2.
Selects the end stop in such a way, that:
> 2
– Hooks, load carrying equipment, and load may not knock
against the rope winch or its supporting structure.
The accuracy of the end stop decreases with increasing
length of the reeled rope.
Adjusting:
z Remove protective cover
z Drive to the "lower" end position (rope unreeled). Adjust a
tappet with adjusting screw until the switch responds.
z Reel rope briefly, stop, unreel again and check "lower" end
position.
z Reel rope and drive to "upper" end position. Adjust the
other tappet with adjusting screw until the switch responds.
z Unreel rope briefly, stop, reel again and check "upper" end
position.
z Drive to the "lower" and "upper" end position again and
correct until end positions are reached satisfactorily.
z Assemble protective cover again.
The limit switch is correctly connected and approximately pre-
set, if the control unit is supplied by the factory. Otherwise it is
the responsibility of the operator to correctly connect the two
switching elements to the control unit.
The limit switch is a safety component.
– Examine regularly, however at least once annually, as well
as before commissioning.
