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 page
14.
• 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. See
sketch
• 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.
