1-7 Operation precautions

1. Mistakes in calculating lifting capacity can cause accidents. So the following should be taken
into consideration:
• The lifting load listed in load chart includes the weight of the hook, rope and slings.
For example: the lifting load listed in load chart is 25000 kg，the weight of hook is 400 kg, the
weight of rope and slings is 100 kg, the actual lifting load of the crane should not be more than
25000-400-100=24500 kg.
• It is very dangerous trying to lift a load without knowing whether it is within the rated capacity, and this should
never be done.
• Operation must be done strictly according to the load charts, it is forbidden to overload.
• It is forbidden to calculate the lifting load by interpolation.
2. During lifting operation, pay attention to the following:
• Safety protective equipments (safety belt, helmet) should be worn when work on structural parts;
• No person and objects piled are permitted within slewing radius;
• Never use the crane as a lifter for transferring person;
• It is not allowed to interrupt common operation by using emergency stop device;
• The crane operation is forbidden whenever the thundering happens;
• The engine running should strictly obey the requirements in Engine technical documents;
• Safe distance between the hook block and boom head must be kept. Lower the hook while extending
the telescopic booms so as to avoid them blocking each other;
• Make sure no person is within the working areas before moving the hook, boom, load or
outriggers;
• Keep window clean to ensure enough vision of view for operator. Dirty windows, darkness,
bright sunlight, fog, rain and other conditions can make it difficult for the operator to see, and
consequently influence the safety of operation;
• Carelessness in getting on and off equipment can result in serious injuries. Always wait until the
machine has stopped. Do not jump on or off. Always use both hands and make sure you have good footing.
Slippery floors and steps, tools, trash, or other loose items can cause falls;
• Always place the boom point directly above the load when lifting. The load will swing out of
control if it is not directly beneath the boom point when lifted. This can side load the boom and may
cause the crane to tip or collapse.
