The invention provides a detection method for an elevator overload protection device. The method comprises the steps that the overload distance changing amount of the distance between a car bottom of an elevator car and a lower cross beam when overload loads are evenly distributed on the elevator car relative to an empty load state is determined; an overload signal collector of the overload protection device is adjusted in the direction of triggering overload protection actions when an elevator in the empty load state; and whether the overload protection device meets a function requirement or not is determined according to whether the overload protection device initiates overload protection actions when the overload signal collector adjusts the overload distance changing amount. By means of the detection method for the elevator overload protection device, a weight measuring tool with the corresponding overload load does not need to the carried, and thus manpower, material resource and financial resource cost is greatly reduced; and the detection method is convenient to operate, high in efficiency and low in cost while an accurate detection result is obtained.
