Safety equipment

EMERGENCY-STOP button
Press the EMERGENCY-STOP button to stop the hoist immedi-
ately in an emergency situation.
Mechanical load limiting device
The load limiting device will active automatically when the over-
load setting is reached. The downward travel of the hoist is
stopped. 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 10).
The system manufacturer / operator is responsible for determi-
ning and setting up the application dependent maximum overload.
For further information see '15.5 Adjustment, Adjusting the me-
chanical load limiting device' on Page 21.
Spring-applied brake
The electromagnetic spring-applied brake automatically locks
when the operating control for travelling UP or DOWN is released
or when the power fails.
Centrifugal brake
A centrifugal brake on the motor shaft of the hoist ensures that
the load is not lowered too fast when the spring-applied brake on
the hoist's motor is released manually.
Operating limit switch / emergency limit switch
During lifting processes the drive path must be limited by one or
multiple limit switches, so that the upward and/or downward
movement is stopped.

The operator or the system manufacturer must determine the
design and the fitting position of the limit switches when taking
their risk assessment into account.
The operator or system manufacturer must install an operational
limit switch and, if necessary, an emergency limit switch and a
floor limit switch and connect them to the hoist. The limit switches
must have a positive opening.
Running hours counter
The running hours can be read from the running hours counter,
in order to determine when the next hoist safety check must be
carried out.
Phase sequence relay (hoists without frequency converters)
In control units operating by three-phase current, the phase
sequence relay shuts down the system in the case of an incor-
rect phase sequence and this prevents an UP / DOWN travel
direction mix-up, which could potentially disable the limit switches
and load limiting devices.
Manual operation switch (optional)
The 'Manual operation' switch interrupts the power supply when
the hand crank is in operating position.

Anchoring

DANGER!
Danger of severe injuries caused by incorrect anchoring!
High-strength, galvanized bolts and screws can become brittle
and break. Risk of falling and of being injured by falling ob-
jects!
– High-strength galvanized bolts / screws (10.9 or 12.9)
may not be utilized for anchoring.
– Utilize bolts / screws with the specified strength.
Specifications detailing the strength of the bolts / screw are listed
in Table 4 on page VIII. Observe the details in 'Structural re-
quirements' on page 6.
The hoist can be anchored with and without an adapter (see pos.
B in Fig. 2).
Anchoring without adapter:
at least 2 screws with self-locking nuts
Anchoring with adapter:
2 screws with self-locking nuts
Bolts of the same strength and equivalent locking can be used
instead of the screws.
