INNOVATION DRIVING CHANGE

Utility Strikes – A Thing of the Past

The Kobus Pipe Puller can minimise the potential risk of damaging surrounding utilities during service pipe replacement. By contrast, moling increases the risk of dangerous strikes.

Saves Time & Costs

Trenchless technology is preferrable to reduce disruption during service pipe replacement. How does the Pipe Puller improve productivity reducing time and costs compared to open cut trenching?

Kobus Pipe Puller Features

Small Footprint

The Kobus Puller is designed with a small footprint.  The tapered design on the foot section allows better clearance from surrounding utilities.  The Puller is positioned easily in small excavations, even  with very congested utilities, and doesn’t require a large clear flat area at the base of the excavation.

Pre-assembled Pulling Cable

Kobus supplies a specially designed pulling cable which comes complete with integral ferrule and expander.  The ferrule allows attachment to the new pipe so it can be towed in behind the old pipe.  The expander opens up the bore hole behind the old pipe.  The cable is ready to use without the need for any fiddly assembly on site.

Continuous Spooling

The Kobus Puller extracts the old pipe continuously providing smooth extraction of the pipe without stopping and starting.  This ensures the pulling is quick without the need for manual operation of any device.  There’s no need to cut the tough old metal pipe with shears that may need regular  replacement.

360deg Rotatable Foot

The 3600 rotatable foot section allows the excavator to be positioned anywhere on the side of the pit to give optimum access.  The rotation of the foot in any direction enables the Puller to be quickly positioned and adjusted without repositioning the excavator for optimum efficiency in operation.

WHAT IS THE KOBUS PIPE PULLER?

Simply, pipe pulling for service pipe replacement is an innovative trenchless technology.  The technique removes old water or gas service pipe from the ground by pulling it with a hydraulic winch and a special steel pulling cable.  At the same time,  a new PE pipe is towed into place along the same bore path created by the extracted old pipe.  Up to 20-25m can be extracted in a single pull.  So, typical lengths of lead, copper, galvanised steel, and PE pipe found on site can all be replaced up to diameters of 1-1/4″ (OD 36mm).  As a result, the process is ideal for road crossings, replacements under expensive driveways/pathways, or where other utilities may prevent other techniques being used.
