CABLE BLOWING MACHINE

摘要

A cable blowing machine that uses pressurised fluid to assist installation of a cable into a cable duct, the blowing machine comprising: a mechanical feeding means (22) driven by a driving means and including a gearing assembly linking the driving means to at least two contra-rotating driving rollers (23) in between which is defined a cable path where a cable is adapted to extend and be moved in a forwardly direction by the mechanical feeding means, wherein the rollers apply equal pressure on the cable, the pressure being adjustable according to the characteristics of the cable so as to increase feeding control of the cable; and a sealed chamber (24) adapted to be coupled to a source (15) of pressurised fluid and to a cable duct (13), the cable path extending through the sealed chamber wherein, in use, pressurised fluid is passed through the chamber and into the cable duct to assist installation of a cable.
