First, check whether suspension mechanism, counter weight, steel wire rope or safety wire rope are meeting the requirement of regulation. Then check the electrical system, it should work normally and have reliable grounding facilities. Start aerial suspended cradle for empty operation, repeatedly lifting up and down, check the lifting mechanism, safety lock, limit switch, brake and motor work, confirm it is normal before formal operation and use. In the winter construction area, it is necessary to clean up the dust, garbage, snow and water slag in the hanging cradle before it can be used.
It is strictly prohibited to operate after drinking, and no joking or playing in the hanging cradle. The materials and tools carried on the cradle must be placed in a flat position. The cradle must not be tilted or overloaded. Do not work on the hanging platform in severe weather with rain and snow or when the wind force exceeds grade 5. When the platform is suspended in the high altitude, the safety lock should be tightened. Loose safety lock when necessary. After 1000h of accumulative use of the safety lock, periodic inspection and re-calibration must be carried out to ensure safe operation.
In case of abnormal sound or fault during operation, the cradle must be stopped immediately for inspection, and shall not be used before the fault is completely eliminated. If the lifting cradle is used for welding, wire rope should be fully protected, and it is not allowed to use the wire rope as a conductive body. Before the cradle is down to the ground, the board should be placed on the ground to avoid damage to the bottom caster. Clean the cradle each day, and hang it 3m off the ground, cut off the power.
During the service period, special personnel should be designated to be responsible for safety and inspection and maintenance. Once the project is completed, it should be fully repaired.
