Adjusting the mechanical load limiting device
DANGER!
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.
– Always abide by the details given in the order specifica-
tions for special versions.
The load limiting device has been set up to activate at a specific
overload. The maximum overload that has to be set up can be
found in the applicable directives and standards (See
' 9.1 Directives and standards' on page 11). The system manufac-
turer / operator is responsible for determining and setting up the
application dependent maximum overload.
The hoist's load limiting device has been set up in the factory to
activate with a maximum permitted overload of 125% of the
maximum working load.
Hoists fitted with mechanical load limiting devices cannot normal-
ly be set up to activate with an overload that is less than 90% of
the hoist's maximum working load.
The maximum overload must be lifted in order to set the load
limiting device.
G1035.2 - 11/2014
Overload = maximum working load + 25 %
Model series X 300 P to X 1030 P, L 500 P
See Fig. 15.
– 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.
Type series X 2050 P
See Fig. 16.
– 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.
