Thick-walled speedpipe ground single ducts in connection: SRV-G with cutting device

The increased admissible tensile force of speedpipe ground especially pays off in the tight relation of the existing capacity to the outer diameter of the speedpipe. Nevertheless, to use the residual space, a cutting device removes the lose duct coat before the drawing-in process. A pulling head that is directly placed on the ends of the speedpipe fixes the single ducts and guarantees an optimum focus of power - without taking more space in the duct. Thus also bundles with more than eight internal speedpipe or additional single ducts can be fed into the duct.
