• Let the cable drum (16) wind up without load until
the safety switch for the upper limit (26) is activated
and the motor stops.
The cable drum must be almost completely wound up
and the hook of the cable hoist (13) must come to a
standstill below the upper release bracket (22).
9.2 Adjusting the safety switches
Adjusting the safety switches
The safety switch for the lower limit and the safety
switch for the upper limit can change position during
operation and can no longer switch off the cable hoist
reliably. It is necessary that you check both safety
switches before each use of the cable hoist, and re-
set them if required.
Setting the lower limit safety switch
You can adjust the release plate, which activates the
safety switch for the lower limit, in the position on the
lower release bracket.
1 Unscrew the locking screw for the release plate
(23) with a spanner.
2 Hold the lower release bracket (20) in its initial
position and adjust the release plate (24) so that it
lightly touches the safety switch for the lower limit
(25) (see Fig. 7).
3 Re-tighten the screw for the release plate.
4 Check the safety switch for the lower limit (see
chapter „Checking the safety switches").
5 If the lower limit safety switch is not activated, re-
peat steps 1 - 4.
Setting the upper limit safety switch
You can change the position of the trigger angle that
activates the safety switch for the upper limit.
1 Screw on the locking screw for the trigger angle
(28) with a screwdriver.
2 Hold the trigger angle (27) in its initial position
and adjust the trigger angle so that it lightly
touches the safety switch for the upper limit (26)
(see Fig. 9).
3 Tighten the locking screw for the trigger angle.
4 Check the safety switch for the upper limit (see
chapter „Checking the safety switches").
5 If the safety switch is not activated, repeat steps
1 - 4.
Checking the brake
Risk of injury!
A faulty braking device on the cable hoist can cause
the load to fall and cause serious injury.
• If the steel cable runs on, immediately disable the
cable hoist and do not use it.
• Have the braking device repaired by a specialist.
The brake ensures a secure hold of the load during
lifting and lowering. For physical reasons, the brak-
ing distance cannot reach zero. However, during this
functional test, it must be apparent that the steel ca-
ble is not running on.
1 Press the toggle switch of the control unit (6) to
the „Lift" position in the direction of the arrow up-
wards and release it again. The steel cable (21)
must not noticeably run on after stopping.
2 Press the toggle switch of the control unit into
the „Lower" position in the direction of the down-
wards arrow and release it again. The steel cable
must not noticeably run on after stopping.
9.3 Increasing the payload
Function: Double payload Fig. (2;4)
1 To mount the pulley on the steel cable (21), dis-
assemble the hook/roller combination (7) into its
individual parts (see Fig. 2).
2 Place the pulley of the hook/roller combination
(18) against the steel cable
3 Screw the hook/roller combination together (see
Fig. 2).
4 Insert the hook of the cable hoist (13) into the
opening for the pulley function (17) (see Fig. 4).
5 Attach the hook of the hook/roller combination to
the load.
6 When lifting the load, let the hook/roller combina-
tion come to a standstill approx. 40 cm below the
safety switch for the upper limit (26).
10. Transport
If you want to move the equipment to a different place,
disconnect the equipment from the power supply and
set it up in the new position you want to use it in.
11. Cleaning and maintenance
Caution! Pull out the mains plug
Clean the rope winch with a rag following use. Keep
the air slits of the motor clean.
After 30 runs (1 run = 1x up and 1x down):
Check the entire steel wire rope (21); in case of dam-
age, replace the steel wire rope according to the
specification (use only original spare parts).
After 100 runs
Check mains cable and control cable for damage.
Check limit switch at upward and downward movement.
After 200 runs
Lubricate steel wire rope and deflecting roller
After 1000 runs
Hook (13/ 19) and deflecting roller (7).
Tighten all screws at the mounting bracket (12) and
the deflecting roller (7).
In case of unusual sounds at the motor or if the load
cannot be raised, the brake system may have to be
overhauled.
For your safety, check the emergency stop
switch (5) and push-buttons before every use.
