to make something quickly or carelessly

crank out means to produce something quickly or carelessly. “Clearly, the gloomy scenario cranked out in the report needs to be taken with a large grain of salt”. I interpret the meaning of this sentenced that the scenarios that are described in the report where forecasted carelessly and are not realistic.
