THE WINCH
Do not exceed the capacity of each rope layer.
Before taking into operation, a competent
person must check:
- the lifting device
- the load bearing parts of the structure
- the carrying medium
- mounting
DAILY EXAMINATIONS
- brake functions
- condition of the rope and loading device
- load bearing parts of the structure.
- the load carrying medium
LOAD ATTACHMENT DEVICE
- check it has sufficient carrying capacity
- load hooks must have safety catches
- load hooks must be secured to the rope with
a solid eye and high pressure rope clamp
and tested according to the regulations
- fix the load correctly
- do not use the winch rope as a hitching
device.
The winch should be given a thorough
examination by a competent person at
least once a year.
Always ensure the maintenance inter-
vals are adhered to.
Only use original accessories and spa-
re parts; otherwise safe function is not
guaranteed.
TECHNICAL DATA (see Tab. 1)
FUNCTIONAL DESCRIPTION
The hand winches are drum winches with spur
gear. The load is automatically held by load
pressure brake.
The winch housing is made of plated steel and
is suitable for mounting, especially onto walls,
masts and similar installations.
The bearing of the rope drum is through rolling
bearing respectively friction bearing.
MOUNTING INSTRUCTIONS
Mounting:
ATTENTION:
- The mounting structure must be designed
to sustain the max. forces imposed by the
winch
- Pay attention that the mounting surface is
flat and true
- Only fix the winch by means of good quality
screws
- Tighten the screws evenly
- Secure the screws
- Ensure that the crank is free running (crank
clearance)

Wire rope fixing
Attention: With wrong rope coiling the brake
is not effective.
Rope coiling has to accordingly the connec-
tion of the winch. The winch should be turned
180° when installed with a downward going
rope descent direction.
Attention: Pay to correct rope direction.
The fastening of the wire rope has to becar-
ried out as follows:
Move the screw with hole through a bore hole
in the side plate (see Fig. 6). Guide the end of
the wire rope through the hole in the screw.
From the outside adjust the nut (see Fig. 7)
and tighten the nut by hand force.
Attention: For rope selection pay to the tech-
nical data for the rope.
Calculate the rope length in such a way that
at least 3 full turns of rope remain on the drum
in lowest load position.
OPERATING INSTRUCTIONS
The winch must first be run with 50%
of the nominal load before operation.
Before operating the winch the drum must
have at least 3 rotations with 50 % of the no-
minal load. The grease of the wormgearing
should be put back into the gearing by means
of a brush. After this operation the winch can
be put into full use.
At least 25 % of the nominal load must be
on the winch as load for the proper working of
the friction brake.
SAFETY INSTRUCTION
The winches are only suited for manual
operation.
- Lifting the load by turning the crank in clock-
wise direction.
- Lowering the load by turning the crank in
counter-clockwise direction.
INSPECTION- AND MAINTENANCE
INSTRUCTIONS
Safety Instruction
Before carrying out inspection and main-
tenance works (see Tab. 2) ensure the winch
is unloaded.
The working life of the winch is limited, wea-
ring parts have to be replaced in good time.
RECOMMENDED LUBRICANT
For all grease lubricating points:
Multipurpose grease acc. to DIN 51825
T1 K 2 K
Waste lubricant has to be disposed acc. to
legal regulations!
OPERATING FAILURES AND THEIR
CAUSES (see Tab. 3)
DISPOSAL
After having placed out of service, the parts
of the hand winch have to be recycled or dis-
posed according to legal regulations!
