The object of the invention is to achieve a universal module that can be fitted to any type of hose, and specifically to the various installations currently used, without making modifications thereto, and which is applicable not only to installations based on a telescopic tube coupled on a side of the boarding finger but also in those cases where the air-supply machine is suspended on the front part of the actual boarding fingers. To that end, the module of the invention consists of a prismatic general body arranged so as to surround a portion of the hose (2), said prismatic body or module comprising two lateral parts based on vertical rods (4) that are actuated for the lateral movement thereof by a gear motor (5) so that, when said vertical rods travel in one direction or another, the corresponding hose is entrained, for extraction or retraction thereof, the rods being arranged between the different coils corresponding to this hose portion. |
