1-24 Safety
Be careful for HV cables
The touching of machinery with or the approaching of machin-
ery to HV cables may cause serious injury or death. Prohibit the
approaching of bucket to electric cables.
The driver shall leave far away from the electric cables with as-
sistance of observer and sign language when the driver’s sight
line is not clear.
Voltage Minimum safety distance
6.6KV 3m(9’ 10’’)
33.0KV 4m(13’ 1’’)
66.0KV 5m(16’ 5’’)
154.0KV 8m(26’ 3’’)
275.0KV 10m(32’ 10’’)
Fig 24
The minimum distances listed this table are only for reference.
The strong electric shock may still occur even the distance
from the big arm or the bucket to the electric cable is 4- 6m
(13-20ft) when the voltage and atmosphere condition changes.
The safety range will be greatly reduced under HV or raining
conditions.
Be careful for operation in ice and snow
places and in very cold weather
Avoid travelling suddenly in cold weather, and do not enter the
very slippery slopping surface. The equipment may slip sudden-
ly towards one side. The accumulated snow may hide or pro-
duce the potential dangers. Take special care for it when you
remove the snow by operating or using the equipment.
In order to prevent the slow action and working performance
degradation, it is necessary to slightly raise the temperature.
The vibration or impact load induced form the large amplitude of
actions of big arm and working device may cause violent stress,
therefore, it is very necessary to reduce working speed and
load.
When the temperature is increased, the frozen road surface will
be softened,therefore, the machine will be unstable when it is
travelling.
Do not directly touch on the metal surface with hands in cold
weather, otherwise, the skin will be stuck on the metal surface.
NOTE: Make contact with Electric Power Company and stipu-
late a safety plan together with the said company be-
fore approaching to the electric cables (cables above
or underground) to perform any forms of operations.
