A device for hauling extended-length tubular shaped objects, comprising: - traction means (12, 13, 14) able to drive, by friction, the object in a hauling direction; - gripping means (110, 112, 113) able to exert a force on the traction means to continuously keep the traction means and the hauled object in contact, the gripping means being set into a relative movement in relation to the hauled object in a direction opposite to the hauling direction; - drive means (115, 116) able to drive the traction means (12, 13, 14) and the gripping means (110, 112, 113) in a coordinated manner to ensure continuous and homogeneous traction of the object; - the traction means (12, 13, 14) comprising a running belt coming into contact with the object to be hauled, which belt is made from a material with high adhesion power; - the gripping means (110, 112, 113) comprising: - two main pulleys (112, 113) and a band stretched between the two main pulleys (112, 113) and helically wound around the object to be hauled and the running belt, so as to exert a force on the running belt to keep the running belt in continuous contact on the object to be hauled; and - a frame free to rotate about the traction axis of the object, made up of two flanges (15, 16) connected by longitudinal struts and traversed by the object to be hauled and the running belt, a first and a second one of the two pulleys (112, 113) being respectively attached onto a first and onto a second one of the two flanges (15, 16); the device for hauling objects being characterised in that it further comprises adjustment means (30, 31) able to adjust the force exerted by the gripping means (110, 112, 113) on the traction means, the adjustment means (30, 31) comprising: - a return pulley guiding the band and being able to be moved relative to the two main pulleys (112, 113), so as to adjust the tension of the band, allowing adjustment of the force exerted by the running belt on the object to be hauled; - a movable flange traversed by the object to be hauled and the running belt, mounted between the first and the second flange (15, 16), the return pulley being attached onto the movable flange, the movable flange being able to be translationally moved between the first and the second flanges (15, 16), so as to adjust the tension exerted on the band. - traction means (12, 13, 14) able to drive, by friction, the object in a hauling direction; - gripping means (110, 112, 113) able to exert a force on the traction means to continuously keep the traction means and the hauled object in contact, the gripping means being set into a relative movement in relation to the hauled object in a direction opposite to the hauling direction; - drive means (115, 116) able to drive the traction means (12, 13, 14) and the gripping means (110, 112, 113) in a coordinated manner to ensure continuous and homogeneous traction of the object; - the traction means (12, 13, 14) comprising a running belt coming into contact with the object to be hauled, which belt is made from a material with high adhesion power; - the gripping means (110, 112, 113) comprising: - two main pulleys (112, 113) and a band stretched between the two main pulleys (112, 113) and helically wound around the object to be hauled and the running belt, so as to exert a force on the running belt to keep the running belt in continuous contact on the object to be hauled; and - a frame free to rotate about the traction axis of the object, made up of two flanges (15, 16) connected by longitudinal struts and traversed by the object to be hauled and the running belt, a first and a second one of the two pulleys (112, 113) being respectively attached onto a first and onto a second one of the two flanges (15, 16); - two main pulleys (112, 113) and a band stretched between the two main pulleys (112, 113) and helically wound around the object to be hauled and the running belt, so as to exert a force on the running belt to keep the running belt in continuous contact on the object to be hauled; and - a frame free to rotate about the traction axis of the object, made up of two flanges (15, 16) connected by longitudinal struts and traversed by the object to be hauled and the running belt, a first and a second one of the two pulleys (112, 113) being respectively attached onto a first and onto a second one of the two flanges (15, 16); - a return pulley guiding the band and being able to be moved relative to the two main pulleys (112, 113), so as to adjust the tension of the band, allowing adjustment of the force exerted by the running belt on the object to be hauled; - a movable flange traversed by the object to be hauled and the running belt, mounted between the first and the second flange (15, 16), the return pulley being attached onto the movable flange, the movable flange being able to be translationally moved between the first and the second flanges (15, 16), so as to adjust the tension exerted on the band.
