Schwing SP 1800-D, Original Operating Instructions

Page: 82 / 390

If your machine comes into contact with high-voltage lines:
● Warn people standing outside the area not to approach or touch
the machine.
● Have the power switched off.
● Only leave the machine once you are sure that the line you have
touched or damaged has been deenergised.
Electricity generator works are always equipped with automatic start‐
up systems. If a circuit breaker trips, the short-circuited line will be
switched back on again after a brief interval. Brief intervals where the
voltage is absent create a false sense of safety.
You must not move or rescue injured persons until a representative of
the power station has notified you that the line has been switched off.
A radio remote control system only protects the machine operator if
he is standing outside the discharge voltage pattern.
2.2.6 Earthing in the event of electrostatic charging
Working in the vicinity of transmitters (radio transmitter, etc.) can re‐
sult in faults in the radio remote control system and dangerous electri‐
cal charges in the machine. Persons who bridge the charged parts to
the earth are heavily charged on contact.
Machines in use in the vicinity of transmitters must be earthed. This
earthing may be carried out by trained personnel.
Even with an earthed machine, the safe clearances to high-voltage
lines
(Clearances P. 32)
and the instructions relating to storms and
bad weather
(Procedure in storms P. 45)
must be complied with.
If you have any further questions about earthing the machine, please
contact site management or the operator of the machine.
2.2.7 Earthing on construction sites with special equipment
When carrying out work in the area of special installations (particular‐
ly overhead lines for railways or substations), it may be the case that
the machine needs to be earthed upon request and in consultation
with the operator of the special installation. This earthing must only be
carried out by qualified personnel.
Even with an earthed machine, the safe clearances to high-voltage
lines
(Clearances P. 32)
and the instructions relating to storms and
bad weather
(Procedure in storms P. 45)
must be complied with.
