Abstract
A method for determining the mass of a car and counterweight of an elevator, running in an elevator shaft along their traveling paths driven by an elevator motor, in which method at least one test run is performed preferably as complete round trip of the elevator car and counterweight, in which test run a) the hoisting system balance m, b) the hoisting system friction F, and c) the hoisting system compensation ΔB is calculated from constant speed data, and in which test run d) the hoisting system inertia mass mis calculated from constant acceleration/deceleration data. From these parameters the weight of the car and counterweight is calculated without any need of weight measurements, but merely by using the power data of the elevator drive unit.
