摘要:
The invention relates to a boom and personnel hoist. The boom (3) comprises at least one elongated boom part (9), the cross-sectional profile of which comprises a top (10), two sides (11), and a bottom (12). The sides comprise at least three sections (20, 21, 22) and corners (N) between them. The bottom parts of the sides are wider than the top parts. The bottom comprises at least five sections (23 to 26) and corners between them. This type of boom and boom part may be in a personnel hoist (1).

The invention relates to a boom, personnel hoist, and method for using a personnel hoist. The boom (3) comprises a first boom part (3a) and a second boom part (3b) connected to each other by a connecting member(8). The boom parts are arranged side by side in the transport position. The upper boom part may be turned into a turning position for use, whereby its axis is on the same vertical plane (T) as the lower boom part. The connecting member comprises a turning axis (K) parallel to the lower boom part.

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).
