Hard solder the rope end clamp to the rope drum with a hexagonal
wrench (SW 4 with 6 Nm, SW 5 with 5 Nm) (fig 1, fig. 2 and fig. 3).
After rotating the crank in clockwise direction, the rope must reel up on
the drum as illustrated in fig. 4.
fig. 4
fig. 1
fig. 2 fig. 3
A functional test must always be accomplished before begin-
ning work.
To extend the service life of the cable, lubricate the cable after it
has been fitted.
7. operATIoN
Lift the load:
Turn crank clockwise.
Lower the load:
Turn crank anti-clockwise.
If the crank is not turned the load (≥ minimum load) is suspended safely.
When lifting a load, do not wind rope beyond the point where at least
1,5 x rope diameter is left free on drum flanges above outermost layer.
When loaded, at least 3 turns of the rope must remain on the
drum. The capacity of the first layer corresponds to the nominal ca-
pacity of the winch. This means that the capacity decreases with every
further layer (refer to type-/ capacity number plate for capacity of first
and last layer).
Version with crank to declutch rope drum (option)
Only for unloaded rope.
Declutchable rope drum:
z
Push crank arm towards the rope winch. The coupling pins move out
of the coupling disc. Unloaded rope can be pulled off.
Clutch in:
z
Pull and turn crank until the coupling pins engage into the coupling disc.
Version with adjustable crank arm (option)
z
Loosen wing screw, adjust crank radius, tighten wing screw.
Version with detachable crank(option)
8. INspeCTIoN
The equipment must be inspected in accordance with the conditions of
use and the operating conditions at least once per year by an authorised
person per TRBS 1203 (Technical expert) (testing per BetrSichV, §10,
sect.2 represents implementation of EC Directives 89/391/EEC and
2009/104/EC and the annual occupational safety inspection per DGUV-
V 54, §23, sect. 2 and DGUV-G 309-007).
These inspections must be documented:
– Before commissioning.
– After significant alterations before recommissioning.
– At least once per year.
– In the event of unusual occurrences arising that could have detrimen-
tal effects on the safety of the winch (extraordinary tests, e.g. after a
long period of inactivity, accidents, natural events).
– After repair works that could have an influence on the safety of the winch.
Technical experts are persons, who have sufficient knowledge based
on their specialist training and experience, in the areas of winches,
lift and pull systems and the relevant official occupational health and
safety rules, accident prevention regulations, guidelines and generally
accepted engineering rules (e.g. EN standards), to evaluate the opera-
tional safety of winches, and lift and pull systems. Technical experts are
to be nominated by the operator of the equipment. Performance of the
annual occupational safety inspection as well as the training required
to obtain the aforementioned knowledge and skills can be provided by
haacon hebetechnik.
9. MAINTeNANCe reCoMMeNDATIoN
The operator determines the intervals themselves based on frequency
of use and the operating conditions.
– Regular cleaning, no steam jets!
– Carry out visual check on inaccessible brakes / locks every 5 years at
the latest, replace brake pads as required.
– General overhaul by the manufacturer after 10 years at the latest.
CAUTIoN!
Only perform inspection, maintenance and repair work on an
unloaded hoist. Only allow work on brakes and locks to be per-
formed by qualified specialist personnel.
Maintenance and inspection work Intervals
Visual check of the rope hooks (load carrier)
Before
every use
Function of the winch
Condition of the rope and lifting equipment
Brake function under load
Grease bearing of drive pinion
Quarterly
Annually
Check rope for wear acc. to DIN ISO 4309 and service
Check fastening bolts for secure seating
Check all parts of the winch and crank for wear, if ap-
plicable, replace defective parts and lubricate.
Annually
Check type plate for legibility
Have an inspection performed by an expert
Lubricant recommendations: Multi-purpose grease per DIN 51502 K3K-20
safety crank
1- 3
30° max
If sluggishness occurs during lowering, pour a
few drops of oil into the gap in the crank cam.
Safety cranks with a gap aperture >30°
should be replaced. Repair must be carried
out by only by the manufacturer.
CAUTIoN!
Only disassemble the crank, ratchet
brace and locking pawl when the
equipment is not under load!
Do not oil or grease the brake pads!
10. operATIoN FAILUres AND TheIr CAUses
Failure Cause elimination
In unloaded state, it
is difficult to turn the
crank
Lubricant in bearing
points is missing.
Dirt or something simi-
lar has accumulated in
the bearing
Execute maintenance
works
Winch was distorted
during mounting.
Check the fixing.
Is the mounting
surface even, are
the screws tightened
correctly
Load is not held Wrong coiling of the
rope winding direc-
tion for lifting was not
correct.
The brake is worn-out.
Lay the rope correctly.
Check brake parts
and replace worn-out
parts.
Too light load The load has to be at
least ca. 20 kg resp.
50 kg
Brake does not
release, load may
only be lowered with
high expenditure of
force.
Brake discs or brake
mechanism is distorted.
Release the brake by
slightly striking against
the crank arm with
the flat of the hand in
lowering direction.
11. spAre pArTs
When ordering spare parts it is essential to quote:
– The type and serial number of the equipment / item and part number
12. DIsAsseMBLY, DIsposAL
– Make sure to observe the safety instructions.
– Dispose of the equipment and the substances within it in an environ-
mentally responsible manner.
