3-8 ZCC1100H Crawler Crane
3.2.6 Electromagnetic influences
Strong electromagnetic fields are likely to be present if the construction site is close to a
transmitter.
DANGER
These electromagnetic fields can pose direct or indirect danger to persons or objects,
for example:
(1) Effect on human organs due to too high temperature.
(2) Danger of burns or inflammation due to too high temperature.
(3) Spark or electric arc formation.
In any case, before working with the crane near transmitters, contact Zoomlion representatives.
In addition, consult a high - frequency specialist.
a) The whole
crane must be “totally” grounded. Check visually or with a simple tester to
ensure that the ladder, cab and cable pulleys are grounded.
b) All personnel working on the crane or with large metal objects must protect themselves
from burns by wearing non-conductive gloves and suitable clothing while working.
c) If one feels a little increase in temperature, there is no need to panic. It is caused by the
influence of high-frequency ray on the tools, structural steel member or support. At this
time, stop the crane safely and leave it at once.
d)
The temperature of objects affected by high frequency radiation depends on their ‘size”.
Cranes, undercarriage
and coverings, for example, are “hotter”.
e) Contacting with other crane loads (arcing) is not permitted when moving the crane. Since
defects caused by burns can reduce rope carrying capacity, any such occurrences must
be reported immediately to the machinery supervisor so that the ropes can be inspected.
f) An insulator is required at all times between the crane load hook and the lifting device. It is
strictly prohibited to remove this insulator.
g) The ropes are strictly prohibited from touching the above insulator.
h) Crane with attached loads may not be touched by any unprotected parts of the body after
the load without insulator has been lifted or put down.
i) Do not work with a bare upper torso or in short pants, this is prohibited.
j) To minimize absorption of high frequency radiation, loads should be transported
horizontally if possible.
k) Loads must be grounded, or additional insulation used (rubber material between the tools
used and gloves) when manual work is required.
l) To avoid accidents, use a safety belt when working on components that are high off the
ground.
For reference only.
Operators manual should be consulted and adhered to.
