The invention relates to the technical field of engineering machinery, and discloses a downhill speed control system, a downhill speed control method and high-altitude operation equipment. The controlsystem comprises a gradient obtaining device used for obtaining the actual gradient of a chassis relative to the horizontal plane; a target rotating speed acquisition device used for acquiring a target rotating speed of the motor; a current acquisition device used for acquiring the actual current of a driver of the motor; a control rotating speed determining device used for determining the presetcontrol rotating speed of the motor according to the actual gradient of the chassis relative to the horizontal plane, the target rotating speed, a preset parameter corresponding relation and the actual current under the condition that the high-altitude operation equipment is in a downhill working condition; and a first control device used for controlling the high-altitude operation equipment to go downhill at the preset control rotating speed of the motor in the next preset control period. Safety control over the downhill speed can be achieved without additionally arranging extra electrical elements.
