The present invention relates to a method of setting the lifting capacity of a lift system having a lift and an overload mechanism. The method comprises connection of the lift to a fixed point via one or more link connectors and a power measurement device. Now, the lift is caused to move to the effect that the one or more link connectors is/are tensioned, and a pull X is exerted on the power measurement device. The pull X exerted on the power measurement device is outputted when the overload mechanism arrests the movement of the lift. Then the lifting capacity of the lift system can be set.
