The embodiment of the invention provides an engineering machinery overspeed fault identification method, a storage medium and a processor. The method comprises the following steps: acquiring the current frequency of a motor and the current rotating speed of a winding drum in the process of controlling the hoisting mechanism to accelerate or decelerate; determining the running time required by the motor to run to the current frequency; determining a first current slope coefficient of the motor during acceleration operation or deceleration operation according to the current frequency and the operation time; determining a second current slope coefficient during acceleration operation or deceleration operation of the motor according to the current rotating speed, the motor parameters of the motor and the operation time; according to the first current slope coefficient and the second current slope coefficient, whether the hoisting mechanism has the overspeed fault or not is determined, the overspeed fault of the hoisting mechanism can be judged in the accelerated operation or decelerated operation process of the motor, whether the hoisting mechanism has the overspeed fault or not is determined in time, and the operation safety of engineering machinery is ensured.
