There is proposed a crane (1) comprising: - an extending boom (6) comprising at least one pair of boom sections (9', 9"), wherein said at least one pair of boom sections comprises: - a first boom section (9') and a second boom section (9") translatingly movable with respect to the first boom section (9') between an extended position and a retracted position, wherein said first (9') and second boom sections (9") have each a proximal end (19) and a distal end (20); - a flexible conduit (17) integrally translatingly connected to the distal end (20') of the first boom section (9') and to the proximal end (19") of the second boom section (9"), so that during the passages from the extended and retracted positions of the second boom section (9"), the portion of the flexible conduit (17) comprised between the distal end (20') of the first boom section (9') and the proximal end (19") of the second boom section (9") gradually flips over; - a device (23) for measuring the extension of the extending boom (6), whereby said device (23) for measuring the extension of the extending boom (6) comprises at least one flexible portion (24) integral with the flexible conduit (17) of the at least one pair of boom sections (9', 9"), and at least one sensor (25) adapted to detect the flipping-over of said at least one flexible portion (24).
