1 Safety instructions
1.1 Symbols In these operating instructions, the following symbols indicate particularly important
information on risks and safety in operation.
Safety at work
This symbol marks all information on safety at work where risks to life and limb are
entailed.
Warning of electrical voltage
Covers such as hoods and caps which are marked with this symbol may only be
opened by "qualified persons or suitably instructed personnel".
Warning of suspended load
It is forbidden for persons to stand under suspended loads. This entails risks to life
and limb!
Safety in operation
Information marked with this symbol must be observed to avoid damage to the chain
hoist or the goods transported.
1.2 Operating instructions Read carefully and follow the operating instructions
In these operating instructions, these symbols mark particularly important infor-
mation on risks and safety in operation.

1 Safety instructions
1.3 Use for intended purpose • Chain hoists are intended for lifting freely movable and guided loads that cannot
tilt. Depending on their design, they are for stationary or mobile use. If loads are to
be towed horizontally, or in the case of guided loads, automatic operation,
continuous deadweight or constantly repeated hoisting motions, the individual
application must be assessed. Contact the manufacturer in case of doubt.
• If the hoist forms "part of a machine," the person placing it on the market must
ensure that the hoist meets the specific regulations of the application.
• Runways, suspensions and endstops must be of suitable dimensions.
• Do not carry out any alterations or modifications. Additional fitments must be
authorised by the manufacturer. The declaration of conformity may be invalidated.
• Load chain hoist only up to the permissible safe working load, following the data on
the rating plate. (Caution: danger of load falling)
Not permitted are for example:
- Exceeding the safe working load
- Transporting persons
- Pulling loads at an angle
- Pulling loads loose, dragging or towing loads
- 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
- Operating the chain hoist without a phase monitoring relay if the control pro-vided
by the customer is not installed in the terminal box on the chain hoist, but for
example in a stationary control cabinet.
1.4 Safety-conscious operation The ST chain hoists are constructed according to the state of the art and equipped
with a slipping clutch as overload protection. In spite of this, dangers may arise from
incorrect use or use for an unintended purpose.
• The operator, see page 2, is responsible for ensuring that work is carried out with
safety in mind and avoiding risks. (EC directive 99/92/EC, Decree on Safety at Work)
• Read the operating instructions before starting to work with the chain hoist.
• Observe the "Duties of crane operator", see page14.
• Before starting work, find out where the EMERGENCY STOP button is (usually in
the control pendant).
•Do not place your hand between edges which may pinch or cut. Seesketch
• Do not use the emergency limit switch (ultimate limit switch for highest and lowest
hook position) as an operational limit switch.
• Report damage and defects to the chain hoist (abnormal noises, impaired braking
function, deformations, ...) to the person responsible immediately. Do not use the
chain hoist until the faults have been eliminated.
• Do not remove information plates from the chain hoist. Replace illegible or
damaged plates.
• Have hoist inspected by the relevant authority before commissioning.
1.5 Organisational safety precautions • Only direct persons to operate the hoist if they have been trained or instructed in
its use. Observe the legal minimum age!
• At regular intervals, check that work is being carried out in a safety-conscious
manner.
•
Observe the intervals specified for periodic tests. File the test reports in the test logbook.
• Store the operating instructions within easy reach where the chain hoist is
operated.

1 Safety instructions
1.6 Electrical equipment Chain hoists, models ST05, ST10, ST20, ST30, ST32, ST50 and ST60, can be supplied
with various versions of electrical equipment.
The chain hoist functions with dangerous electrical voltages.
• Disconnect the chain hoist before opening covers marked with this symbol.
• The chain hoist may only be opened by qualified personnel (see page 2) or person-
nel having been instructed.
a) Direct control:
The motor of the chain hoist is switched on and off directly, i.e. without the use of
contactors. Mains voltage and mains current are present in the control pendant. Due
to the limited ampacity of the control pendants, direct control is only available up to
1.6 kW motor output at 400 V, 3 ph, 50 Hz. Direct control is not permissible in various
countries (e.g. Canada, U.S.A.) due to legal stipulations and standards.
b) Contactor control:
The motor of the chain hoist is switched by means of a contactor-transformer combi-
nation.
A safety extra-low voltage is present in the control pendant.
Contactor control is available for all motor sizes and outputs and is accepted world-
wide. The control voltage generated by the transformer is selected corresponding to
customer requirements and national standards. 48 V or 230 V control voltage is gene-
rally used in Europe, 120 V in North America.
c) Version without control:
STAHL chain hoists are available without control. The switchgear (e.g. contactors
and transformer) are then not supplied. The rectifier for activating the brake remains
part of the supply.
Safety note: if the hoist is supplied without control, it is recommended that the custo-
mer install a phase monitoring relay. If the control is not installed in the terminal box
on the chain hoist, but in a control cabinet for example, a phase monitoring relay is
obligatory.
If the control is supplied by others, or work carried out on the control, the braking
function must be tested.
1.7 Warranty • The warranty will become invalid if these operating instructions are not observed
for installation, operation, inspection and maintenance.
• Repairs and elimination of faults within the scope of the warranty may only be per-
formed by qualified personnel (see page 2) after the manufacturer/supplier has
been consulted and has given his approval.
The warranty will become invalid if the hoist is modified or original spare parts not
used.
1.8 Periodic tests Hoists and cranes must be inspected by a qualified person, see page 2, at least once
a year. The results of the test must be recorded and filed in the test log book.
The remaining service life of the hoist acc. to FEM 9.755 must also be established
during this inspection.
The periodic tests must be adapted to the hoist’s use. Intensive use entails shorter
maintenance intervals.
All tests must be initiated by the user, see page 2.
