Rail-guided handling equipment must be switched off immediately in the event of
the following faults:
• Damage to electrical devices and cables as well as parts of the insulation.
• Brake and safety device failure.
Ensure that nobody is endangered by operation of rail-guided handling equipment
before switching it on or putting it into operation.
If the operator notices persons who may be exposed to a risk to health or personal
safety by operation of the equipment, he must suspend operation immediately and
may not resume operation again until the persons are outside the danger zone.
Before putting rail-guided handling equipment into operation, the operator must be
satisfied that it is in safe and correct operating condition.
Work on rail-guided handling equipment may only be carried out when instructions
to this effect have been issued, when operation and function of the equipment have
been explained and when the working and danger zone has been made safe.
Cooling devices and ventilation openings, may not be rendered permanently inoper-
ative (e.g. covered or closed).
Special local conditions or special applications can lead to situations which were
not known when this chapter was written. In such cases, special safety measures
must be implemented by the owner.
Maintenance measures are defined as regular maintenance, inspection and repair
work.
Mechanical and electrical repairs and maintenance work may only be carried out by
appropriately trained personnel (experienced technicians). Demag specialists are
also trained to work on specific products.
Adjustment, maintenance and inspection activities and inspection deadlines includ-
ing specifications concerning replacement of parts/assemblies prescribed in the
assembly and operating instructions must be observed.
Ensure that all electrical components are de-energized before commencing work on
electrical installations and devices. When all work on rail-guided handling equipment
has been completed, operation of the equipment must not resume until the owner
has given approval to this effect.
Unauthorized persons must be prohibited from carrying out work on machinery or
parts of rail-guided handling equipment. Before starting all repair and maintenance
work, the product must be switched off, taken out of operation and secured
(switches must be locked) against accidental or unauthorized putting into operation
(restarting).
It must be ensured that
• rail-guided handling equipment is switched off and checked that it is de-ener-
gized and, in special cases, isolated,
• moving parts are stationary and stopped,
• moving parts cannot start moving while maintenance work is being carried out,
• the power supply cannot be accidentally restored as long as the rail-guided
handling equipment has been taken out of service for maintenance and repair
purposes, Ensure that operating and auxiliary materials as well as replaced parts
are disposed of in a safe and environmentally sound way.
