10.7 Switching off when overloaded

Hoists fitted with mechanical load limiting devices:
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. A warning signal will be sounded or a
warning light will come on when it is switched off.
Jamming of the load lifting equipment may also lead to deactiva-
tion.
Overload is generated by a stationary drive during loading:
– Reduce the load until no overload is present.
Overload is generated when moving upwards, e.g.
 by jamming:
– Lower or release the hoist until the load hangs freely again.
– Remove the obstacle before lifting the load again.
from loading up to the load limit with greater travelling

heights, due to the fact that the own weight of the cable that
has to be carried by the hoist increases with the increasing
height.
– Move the hoist down and reduce the load.
– Where applicable, readjust the overload, see
' 15.5 Adjustment, Adjusting the mechanical load limiting de-
vice' on page 23.

Foreseeable misuse

Guarantee and liability claims for personal injuries and equip-
ment damage will be rejected if they can be traced back to one or
more of the following causes:
 Unauthorized use of the product, the accessories or the
carrying means belonging to the product
 Operating with a soiled wire rope
Operating without limit switch (hoist for lifting)

 Use in potentially explosive or corrosive environments
Not adhering to the stipulated maintenance periods

Cleaning with a high-pressure cleaner

 Incorrect installation, commissioning, operation, mainte-
nance or repairs
 Working with an electrical connection that does not corre-
spond to the details stipulated in this manual
 Poor monitoring of the parts and the accessories, which has
resulted in wear occurring
 Carrying out incorrect and unauthorized repairs
Use of non-original spare parts

 Alteration of safety device settings
Ignoring measurements and checks that would detect early

signs of damage
Product overloaded

G1035.2 - 11/2014
 Directly anchoring the load to the towing/suspension wire
rope (wire rope without a thimble or hooks
 Accidents caused by foreign bodies or force majeure
The manufacturer will not accept any liability for damages

resulting from modifications and conversions made to the
products or from the use of non-original parts that have not
been authorized by the manufacturer.
Never use faulty or damaged products, accessories and,

rigging.
Recommissioning following the failure of an EMERGENCY-

STOP function without overhauling (see ' 10.3 Measures fol-
lowing an emergency stop' on page 17).
 Loading the unloaded side of the hoist with more than
100 kg (e.g. via the wire rope pretensioning).
 Downwards travel by venting the brakes (only permitted in
emergency)

Dismantling

DANGER!
Risk of injury through stabs and cuts!
Broken wires in the wire rope can result in protruding wires!
Protruding wires can cut or stab through safety gloves!
– Wear suitable leather protective gloves when working
with wire ropes.
– Never let the wire rope run through your hands.
– Lower the load lifting equipment and remove if necessary.
– Press the DOWN button and pull the wire rope upwards out
of the hoist.
DANGER!
Danger of death due to electric shock!
– Disconnect the hoist from the power supply by pulling out
the plug.
– Pull out the power plug.
– See Fig. 5: Whilst lowering wind up the wire ropes (1) in the
correct position or onto a reel to ensure that there are no
loops (2), which would make the wire ropes unusable.
– Loosen the anchorage of the hoist.
– Dismantle the deflection rollers and load bearing points.
