Installation and operating manual
G961.1 - 03/2012 EN-15
ATTENTION!
Damage due to incorrectly adjusted clutch!
The required clutch force depends on the rope weight on the
driven reeler. If the clutch force is set too high then this can
result in premature wear or damage. The hoist set up is fac-
tory-made.
–
Do not adjust the clutch force!
Fit the stop disc for the upper drive path lim-
iter
A stop disc must be fitted as the upper drive path limiter for the
emergency limit switch and the optional operating limit switch.
See Fig. 22.
Item Name
1 Rope anchoring
2 Stop disc
3 Limit switch (similar to illustration)
4 Suspension wire rope
The gap between the limit switch and the wire rope anchoring or
the protruding components must be chosen so that the machine
can be switched off reliably and in good time. We recommend
that you use a minimum gap (Size a) of between 0.5 to 1.5 m.
–
The stop disc (2) must be mounted below the rope anchor-
ing point (1) on the suspension wire rope (4).
After completing the installation
– Check that everything is ready and then run a functional
check, see '9.4 Commissioning' on page 15.
9.4 Commissioning
ATTENTION!
The load will be incorrectly secured to the ropes if thim-
bles or hooks are not used!
Can result in damage to the device!
The load must not be directly attached to the towing rope.
–
Use a wedge clamp and an anchorage rope to anchor
the load.
Determining operational readiness
– Check the rope anchoring.
– Check the anchoring of the hoist, deflector rollers and the
load.
– Check whether the rope enters the hoist vertically.
– Check that the rotation of the free reeler/driven reeler is not
impaired.
– Check that the plugs on the motor (see Fig. 27, Item 3) are
seated correctly.
– Record the inspection results in the logbook.
Functional test
DANGER!
Risk of being injured by falling objects!
– Never stand beneath suspended loads.
– Cordon off the hazard zone whenever necessary.
ATTENTION!
Incorrect rope lengths!
Can result in damage to the device!
The rope end connection, the load bearing point or the rope
end itself must never be pulled up to or into the product or the
accessory parts!
–
Use a rope with adequate length.
– Whenever necessary: Monitor the rope during operation.
Note (hoists without frequency converters):
If the hoist fails to start then two poles in the power supply cable
may have been inverted. The built-in reverse polarity protection
locks out the control unit:
–
Turn the phase reverser in the plug by 180°, see Fig. 24.
Load up the load lifting equipment
The load lifting equipment or the hoist must be loaded with the
maximum working load during the following tests in order to be
able to test that the safety devices work correctly.
– The operator or the system manufacturer must ensure that
the payload can be traversed against the static friction in a
manual emergency descent in any situation (e.g. if the rope
is reeved) and that the maximum working load is not ex-
ceeded.
– Load the load lifting equipment with the maximum working
load.
Where necessary, take other information given by the operator /
system manufacturer into consideration.
Testing the brake
– Run the hoist in the pulling direction until the rope is ten-
sioned (run hoists with two speeds at the lower speed).
– Raise or pull the load along for approx. 1 m.
– Stop hoist:
The brake must hold the rope tightly.
