A boom for a personnel access lift comprises at least two boom sections (9, 10), namely a first boom section (9), pivotally supported at a first pivot point (14) in the region of a first end thereof, and a second boom section (10) pivoted at a second pivot point (15) spaced from an end of said second boom section (10) upon a pivot in the region of the other end of said first boom section (9). A link (16) pivotally connects a first link point in the region of said end of the second boom section and a second link point (17) fixed relative to but spaced from the first pivot point (14), such that the link (16) extends at an angle across the length of the first boom section (9). Hydraulic means (19) are provided for moving the first boom section (9) about the first pivot point (14).
