Installation and operating manual

EN-24

G961.1 - 03/2012

The maximum overload must be lifted in order to set the load
limiting device.
Overload = maximum working load + 25 %

Adjusting the mechanical load limiting device

See Fig. 30.
–

Load the load lifting equipment with the calculated overload.

–

Raise the load.
The load limiting device must react and stop the UP travel of
the hoist within the first 10 cm.

If the load limiting device does not react:
–

Remove the blanking plug (1).

–

Loosen the brass screw (2).

–

Insert an 8 mm, 150 mm-long Allen key into the setting
screw (3).

–

Loosen the setting screw (3) until the load limiting device
reacts.

–

Lower the overload to the ground.

–

Raise the overload again.
The load limiting device must react. Otherwise repeat the
procedure.

The load limiting device must not react when the hoist is loaded
to the maximum working load.
–

Load the load lifting equipment with the maximum working
load.

–

Raise until the load lifting equipment hangs freely.
The load limiting device must not react when lifting the load.

If the load limiting device reacts:
–

Lower the load to the ground.

–

Insert an 8 mm, 150 mm-long Allen key into the setting
screw (3).

–

Tighten the setting screw (3) one half turn.

–

Raise the load again.
The load limiting device must not react when lifting the load.

If setting screw (3) was adjusted, repeat the test with the maxi-
mum overload.
–

Load the load lifting equipment with the calculated overload.

–

Raise the load.
The load limiting device must react and stop the UP travel of
the hoist within the first 10 cm.

–

Tighten the brass screw (2).

–

Replace the blanking plugs (1) and secure with red sealing
wax.

Adjusting the electronic load limiting device (optional)

DANGER!

Danger of death due to electric shock!

–

Disconnect the power supply to the hoist by disconnect-
ing the connector before opening the terminal box.

–

Do not touch any conducting parts when performing the
adjustment.

–

Cover conducting parts if necessary.

Risk of being injured by falling objects!

Might result in severe injuries or even death!
–

The load limiting device may only be implemented by
personnel authorized by the system manufacturer or
TRACTEL Greifzug GmbH.

–

Observe the details in this instruction manual.

The electronic load limiting device reacts to the power consump-
tion of the motor. Hoists with two speeds are equipped with two
electric load limiting devices. The adjustment must be made for
both load limiting devices and speeds. The overload is recog-
nized when lifting.

A lower limiting value, e. g. due to a lower load bearing capacity
of the anchoring points, must only be set by authorized mainte-
nance personnel.

Default setting

See Fig. 28.
–

Remove the sealing wax on the controllers (1) and (2).

–

Turn the upper controller (1) for the rated power to the right
to the limit.

–

Turn the lower controller (2) for the start monitoring to the
right to the limit.

Adjusting the overload

–

Load the load lifting equipment with the calculated overload.
