The design is not standard, such as overload protection failure, balance wheel, shaft strength is not enough, no anti-decoupling device, sling, rope selection is not reasonable, otherwise it can not be replaced in time, lack of necessary safety protection, maintenance is not in place. Abnormal operation, resulting in loss of control of movement, damage to parts or structures, abnormal safety. The detection of environmental factors such as high dust, high temperature, high humidity, low temperature, high noise, windy days and poor lighting will distract people's attention, directly affect workers' reactivity and technical stability, increase the probability of misoperation and reduce work efficiency.
