Modifications of the design and execution reserved.
Special design! Pay attention to the serial number plate and the drawing.
Rope recommendation:
EN 12385 Tab. 12-6x19M - WSC- 1770 B sZ
* for type 242.3 EN 12385 Tab. 9-6x36WS - WSC - 1770 B sZ
** required for the function of the load pressure lock.
5. constrUctIon
Standard design: Spur gear and safety crank with integrated load
pressure lock (single-acting) and maintenance-free slide bearings.
6. InstallatIon
The bore pattern can be use to attach the gear drive. Suitably long
screws should be used.
Should the gear drive be welded to a structure, the welds should not be
in the area of the gear drive bearings.
7. fIttIng tHe rope (WHen UseD as a rope WIncH)
If rope is fed in incorrectly –> (spare parts diagrams) the brake is
ineffective!
It is best to hard-solder the end of the rope and lock it to the rope
drum. When the crank is turned in a clockwise direction, the rope
should wind up.
8. operatIon
Move the crank handle by 90° into its working position.
When used as a rope winch
to lift the load: Turn the hand crank clockwise.
to lower the load: Turn the crank anticlockwise.
If the crank is released during lifting or lowering, the load (minimum load
–>Techn. data) is held in its current position.
The rope pulling force of the first layer is the same as the nominal pulling
force of the winch. The pulling force decreases for each additional layer
of rope (–> Technical data).

When used as a gear unit with a single-acting locking mechanism
When turning the crank clockwise, the torque built up is held by the
locking mechanism.

9. InspectIon
ø 12*
The equipment must be inspected in accordance with the conditions of
90,5
use and the operating conditions at least once per year by an authorised
31
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.
10. 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/Inspection work general
Brake function under load
Grease bearing of drive pinion
Check fastening bolts for secure seating
Check all parts of the winch and crank for wear, if appli-
cable, replace defective parts and lubricate.
Check and wait for the lock (see below)
Check type plate for legibility
