Strong electromagnetic fields are likely to be present if the construction site is close to a transmitter.

These electromagnetic fields can pose direct or indirect danger to persons or objects, for example: 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.

(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.

m) Handling explosive matter (such as refueling) may only be carried out at least 6 m away from the place where sparks could form due to handling of large metal parts. Use only conductive rubber hoses to refuel.

n) Any accidents and unexpected events must be reported immediately to the local project manager and the safety engineer.

3.2.7 Safety signs

The positions on the crane that may pose danger or potential danger are labeled with safety signs. The arrangement of safety signs on one side of the crane (i.e. near the ladder on the slewing table) is shown in the figure 3-1. The arrangement of safety signs on the other side of the crane (i.e. near the operator’s cab) is shown in the figure 3-2. As to the description of safety signs, please see the table 3-1.

Caution

(1) When the safety sign is damaged or illegible, please order it from appointed supplier.

(2) It is forbidden to cover or take off the safety signs casually.

(3) If the safety sign is covered with dust, clean it in time.

(4) The operator’s cab should be equipped with an emergency hammer which can be used to smash the window in an emergency so that the operator can run away from the cab in an emergency.

3.2.8 The potential dangers existing in crane operation

a) Do not stand under a suspended load!

b) No one should be in danger zone of the machine.

c) Do not reach into moving drives or parts of the machine.

d) Access to the top of the upper carriage is only permitted

To carry out assembly, maintenance or service work, e) Secure the open sliding doors or the front windscreen of the cab, as well as the open engine compartment doors, against inadvertently closing. f) When driving bolts or pins in or out,

– With appropriate safety measures against falling, such as wearing non-slip boots. Do not walk on the roof of the operator’s cab.

– Never stand between or below the boom intermediate sections,

– Never align bolt connections by hand,

Use appropriate special tools (mandrel, stud wrench, etc), g) Safety instructions and preventive measures to avoid mechanical hazards:

Always wear safety goggles.

1) Only remove protective hoods and safety covers

– When the machine has come to a standstill or

– Is secured against an accident restart.
