    摘要： The invention relates to a ladder of a personnel hoist, to a personnel hoist and further to a method for using a ladder. A boom (3) of the personnel hoist (1) is provided with a ladder (8) comprising ladder frames (11), steps (13) and rails (9) that can be moved up and down. The rails are arranged to be turnable between an upper position and a lower position in such a way that they move in the longitudinal direction of the ladder without transverse motion. The rails are turned by means of the turning actuator (16), and the turning motion is transmitted between the rails by means of a connecting bar (19).
