Operator’s 履带起重机操作手册 Manual for 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. Safety Guidelines
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.
安 全 准 则
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.
