5.3.2 Earthing (Optional extra)
Before using the machine at or nearby e.g. transmitting stations, wind
power stations or transformer stations it maybe becomes necessary to
earth the Ruthmann-Steiger according to the instructions of the operator.
When using the Ruthmann-Steiger nearby wind power stations static
charging can make an earthing of the „Ruthmann-Steiger“ necessary. The
radius, within which earthing measurements become necessary, depends
on the transmitting power of the transmitting station and on the lifting
height of the working cage. With big machines this can even be several kil-
ometres.
Further information concerning this can be obtained from the owner. Kind
of earthing of the Ruthmann-Steiger must be agreed with the persons re-
sponsible for the plant and for the work.
The following connections (earthing cable, cross section
≥
50 mm
2
) must
at least be established :

from working cage to boom (lifting arm),

from boom (lifting arm) to turret,

from turret to chassis,

from chassis to earth.
It can also become possible that the person responsible for the plant or for
the work prescribes to lay an earthed metal grid on the working cage floor.
