ABSTRACT:
The invention relates to a haulage machine for hauling an elongate cylindrical unit (e.g. a cable) along a conduit or duct (3), said machine having a winch (11) on which a haulage rope (9) is wound, said haulage rope being hitched to the cylindrical unit (7) by a haulage head (8); one or more independant auxiliary haulage devices (1) are disposed at points (2) of access to the duct, each auxiliary device having drive rollers (6, 6'). The haulage head (8) is connected to signal to a regulator device (15) (e.g. via conductor wires contained in the haulage rope (9), to indicate the haulage force it is applying and each auxiliary haulage device (1) has a variable discharge rate pump (4) which controls a hydraulic motor (5) whose output shaft rotates the drive rollers via clutches.
