The support and guidance structure includes a support () equipped with means of guidance () of the mast () in a raising direction (Z), including a wall () extending in this direction (Z), and delimiting a housing () for the mast (). The guidance means () include two guide rails (), borne by the support (), and two additional guidance elements (), borne by the mast (), each operating in tandem with a respective rail (). Each rail () forms stops (A) immobilizing the related guidance element () in a second direction (Y) perpendicular to the raising direction (Z) and the wall (). The guidance means () include another guide rail (), borne by the support (), and another additional guidance element (), borne by the mast (), and operating in tandem with the other rail (). The other rail () forms stops (A) immobilizing the other guidance element () in a third direction (X) perpendicular to the raising direction (Z) and the second direction (Y). The housing () is open on substantially all planes perpendicular to the raising direction (Z).
