Safety regulations 1
1.5.2.22 Make sure that fuel, accessory material and
interchanged parts are safely disposed of with no danger
to the environment.
1.5.2.23 The machine should be checked by a specialist
before commissioning. In addition, it should be checked
after essential modifications before it returns to service.
1.5.2.24 The machine must be checked by a specialist
once a year. Furthermore, a specialist must check the
machine whenever necessary because of operating condi-
tions.
1.5.2.25 The test results must be recorded and kept in the
archives at least until the following control date.
1.6 Instructions regarding special cate-
gories of danger
1.6.1 Electrical energy
1.6.1.1 Only use original fuses (mandatory current).
Immediately switch off machine in case of breakdown of
electrical supply.
1.6.1.2 When working near overhead lines and overhead
wires, a safety clearance must be kept between the
machine and its working equipment in order to prevent
sparking over. The safety clearance depends on the nominal
voltage of the overhead/wire line. This also applies to the
distance between the lines and to the attachments and
slung loads.
The following safety clearance must be observed, to meet
the above mentioned requirement:
Nominal voltage Safety clearance
(kilovolt) (meter)
up to 1 kV 1,0 m
above 1 kV up to 110 kV 3,0 m
above 110 kV up to 220 kV 4,0 m
above 220 kV up to 380 kV 5,0 m
unknown nominal voltage 5,0 m
When approaching overhead lines all working movements
of the machine must be taken into consideration, e.g. the
position of jibs, the swinging of ropes and the dimensions
of slung loads.
In addition, attention must be paid to any roughness of soil
which could cause an inclined position of the machine thus
getting it closer to the overhead line. The fact that overhead
lines may swing out during windy weather and may reduce
the distance must also be taken into consideration.
