Maintenance and service work
Check braking torque (–> following description)
Check all parts of the lock for wear, relubricate
and if necessary replace defective parts.
recommended lubricants (lock):
DIVINOL grease Fibrous 2 acc. to DIN 51502 KP2K-20
replacement of lock (–> spare part drawing)
– Relieve the tension on the winch (secure any loads to be lifted in
an appropriate manner) or disassemble the winch and lay it down
horizontally.
– Knock out the clamping sleeve.
– Detach the receptacle.
– Loosen the nut (SW 24).
– Dismount the lock.
lock
checking the braking torque
– Remove the lock (see above) with the lock underside underside
facing up. The cast iron housing must not turn.
All moving parts of the lock must still be able to move after it is
attached.
– Measure the torque on the square output square drive with a torque
gauge.
Perform one clockwise measurement and one anticlockwise measu-
rement.
– The torque of a new lock is –> 90 Nm.
Do not exceed a braking torque of 90 Nm.
Replace the lock!
assemble the lock in the reverse sequence. When doing so, pay
attention to the following:
– The bolt must dip in the locks slot hole (Torque support).
– Tighten hex nut with 90 Nm.

attentIon!
Safety component, particular attention.
check daily, before every use
– The crank must be able to move easily back and forth in
small range.
– The square shaft must not move when the crank arm
moves!
– The range of movement must
– be at least 5° (3 cm on the crank handle).
– not exeed 20° (9 cm on the crank handle).
– If the crank arm cannot move easily or
– if the movement range becomes larger or smaller
than indicated, the brake has been damaged or
is inoperable.
the equipment must not to be used under any
circumstances and should be checked
immediately by a technical expert.
An immediate ispection by a professional should be performed if:
– the crank arm bounces when the load is beeing lowered.
– the crank arm blocks during the rotation of a small load.
– the crank squeaks.
lubrication
The crank is initially lubricated by the manufacturer with a long-term lu-
bricant. The lubricant durability depends on the operating environment
(weather conditions) and usage intensity. In most cases it is sufficient to
lubricate the safety crank during the scheduled inspection intervals.
Lubrication with the appropriate oil can be performed by the operator.
By doing this, deposits and contamination, as well as old lubricant, will
be dissolved and washed out, and the rust protection refreshed.
Even a single lubrication with oil will destroy the longterm effect
of the original lubricant. Once it is done, oil lubricant has to be
repeated regularly in short intervals, especially if under the
influence of bad weather or aggressive substances. Furthemo-
re, oil lubrication decreases the ease of operation while working
with heavy loads.
lubrication with fine mechanics oil
Spray oil into
lubrication holes
– Remove all weight from the crank.
– Put the crank in the vertical position up.
– Spray the oil generously into the 2 lubrication holes and into the nar-
row gap between the crank and the security ring.
– Divide the oil evenly by crank arm rotation in both directions. Repeat.
– Use only lubricants mentioned.
Lubrication performed by a non-expert could lead to brake
failure. Severe danger of serious accidents.
No degreasing agent, varnish or paint should be poured through
the gap on the front and back side into the inner part of the
crank. This could lead to brake failure.
Severe danger of serious accidents!
lubricant recommendations (double acting locking, crank):
Fine mechanics and care oils – e.g. WD40 or Ballistol.
lubricants that are not acceptable:
Greases, pastes and thick oils.
Oils with adhesives (chain oil).
Lubricants that contain MoS2.
