The invention relates to equipment (10) for making a structural element (1) of composite material having a longitudinal axis (A) and an axial cavity (2). The equipment (10) comprises a support frame (11) and a laminating mandrel (12), which is mounted on the support frame (11) so that it can rotate about its own central axis (B) and defines an outer laminating surface (13); the support frame (11) comprises two vertical headers (14, 15), facing each other and parallel to each other, and longitudinal connecting means (16) for longitudinally connecting the headers (14, 15); each header (14, 15) comprises a fixed portion (17) and a movable portion (18), coaxially receiving the laminating mandrel (12) and rotatable about the central axis (B) in relation to the fixed portion (17); the laminating mandrel (12) comprises a central shaft (26, 26' ), a plurality of sectors (30) angularly spaced apart about the central axis (B), and a plurality of linear actuators (31) extending between the central shaft (26, 26' ) and respective sectors (30) to move the sectors (30) themselves between an expanded laminating position and a contracted position; the equipment (10) further comprises first constraining means (35) for connecting in a releasable manner the sectors (30), arranged in the expanded laminating position, to the movable portions (18) of the headers (14, 15), and second constraining means (36) connecting the linear actuators (31) to the sectors (30) in a releasable manner so as to enable the extraction of the central shaft (26, 26' ) and linear actuators (31) from the equipment (10) in the condition in which the sectors (30), in the expanded position, are connected to the movable portions (18) of the headers (14, 15) by means of the first constraining means (35).
