2Safety instructions
2.1 Use for intended purpose
•Chain hoists are intended for lifting freely movable loads. Depending on their design,
they are for stationary or mobile use.
•Chain hoists for "guided loads" have to be specially designed for this type of applica-
tion. Pulling/towing or raising/lowering of a guided load is then only permitted if the
chain hoist or system is designed for that purpose.
•Runways, suspensions and endstops must be of suitable dimensions.
•Any fundamental alterations and modifications to the product, such as e.g. welding on
load-bearing components, structural alterations to load-bearing components, altera-
tion of drives, alteration of speeds and motor outputs, replacing trolleys, etc. must be
authorised by the manufacturer, otherwise the declaration of conformity/declaration of
incorporation will be invalidated.
•Also any work on or additions to the control must be authorised by the manufacturer.
The manufacturer cannot accept any liability for malfunctioning after unauthorised
work on the control.
•Load hoist only up to the maximum working load, following the data on the rating
plate. (Caution: danger of load falling).
•The conditions in the place of use of the hoist must correspond to the operating
conditions for which the hoist was designed (including indoor/outdoor use, ambient
temperature, radiation temperature, wind, dust, splash water, snow, water, etc.
•For hoists which work in combination and have more than one control (tandem
operation), action must be taken to coordinate the controls. This applies also to the
reaction of the protective devices.
•For hoists intended for automatic operation, the control must be designed accordingly
•In the case of chain hoists with multiple load-bearing equipment, ensure that the load
is distributed evenly between the falls. Any asymmetry arising must not exceed the
maximum load stated on the corresponding load capacity plate.
2.2 Inappropriate use
•Use in areas with potentially explosive atmosphere.
•Transporting molten metal.
•Exceeding the maximum working load.
•Transporting persons.
•Use of the hoist in applications where the load during a lifting procedure may exceed
the maximum load-bearing capacity (e.g. single-sided attachment of long items), if no
additional overload safeguard is present.
•Pulling loads loose, pulling or towing loads
•Pulling loads at an angle, dragging loads or moving vehicles with the load or load
suspension equipment
•Do not knot load ropes or chains or shorten them with devices such as bolts, screws
or similar
•Removing the safety latch from suspension and load hooks is not permitted
•Manipulating the slipping clutch
•Operating the hoist with slack chain
•Touching the chain during the hoisting motion
•Operating a damaged hoist
•Operating the hoist with the chain twisted
•Approaching the emergency limit switch in normal operation
•Approaching top and bottom hook position (slipping clutch) in normal operation.
•Manipulating the overload safety device.

•Operating the chain hoist without a phase monitoring relay if a control supplied by the
customer is not installed in an electrical connection box on the chain hoist, but e.g. in
a stationary control cabinet.
•If the product forms "part of a machine," the person placing it on the market must
ensure that the product meets the specific regulations of the application.
•Application of external torques due to forces that are exercised from outside the
system, e.g. with gripper operation or through tilting/bumping of the load, in particular
with the option 4×90° hook locking.
2.3 Residual dangers
The machine has been subjected to a risk analysis. The design and construction based
on this correspond to the state of the art. However, residual hazards remain during
operation and maintenance and these could result in serious or even fatal injuries to
personnel.
•Risk of crushing
•Hazard due to falling parts (attached to the load or on the load)
•Load toppling due to unsuitable or damaged load-bearing equipment
•Risk of electric shock
Preventative measures:
•The machine functions with high voltage.
•Switch the machine off and ensure it cannot be switched on again before carrying out
maintenance, cleaning and repair work.
•Switch off the power supply before all work on the electrical system. Check that the
components to be replaced are free of current and voltage.
•Do not remove any safety devices or override them by manipulating them.
•When lifting or lowering loads ensure that no-one is in the immediate danger area.
•It is forbidden for anyone to stand in the danger area.
2.4 Organisational safety precautions
