Fifth, in strict accordance with the command signal operation, the emergency stop signal, regardless of any person to issue, must be implemented immediately. Sixth, hanging close to or reach the rated load, or lifting of dangerous goods (liquid metal, hazardous materials, flammable and explosive materials), the lifting carefully check the brakes before, and with a small height, short travel suspension test, confirmed that no problems then lifting. Seventh, all parts of cranes, hoists and ancillary equipment and transmission line containing the minimum distance should meet the safety requirements; Eighth, there is the following circumstances, the driver should not operate: (1) crane structure or components (such as hook, wire rope, brakes, safety devices, etc.) affect the safety defects and damage; (2) hanging objects may be overloaded or overloaded, lifting the total weight is unclear, embedded or frozen in the ground, squeezed by other objects, the operation may not pull oblique hanging crooked; (3) hanging objects bound is not strong, or hanging instability, heavy edges and corners and not between the padded sling; be suspended or floating material on the one compartment; (4) operation sites in the dark, blind to the venue, the situation hanging objects or command signals.
