Pipe puller KPP series

The KOBUS Pipe Puller technology has been developed for trenchless house connection renewal using the static winding method. The method can be used to renew gas and water house connection pipes made of copper, lead, steel and polyethylene (PE) from DN 15 (1/2”) to DN 32 (1 1/4”) mm without trenching. The sectional length is up to 25 m depending on the subsoil conditions and the local conditions. Polyethylene (PE) pipes up to a diameter of DN 40 (1 1/2”) are used as new pipes. The old pipe can be replaced with a new pipe that has the same dimensions or that has larger dimensions. Both standard pipes in SDR 11 and pipes with protective properties can be used. It is also possible to install a protective pipe for the installation of the product pipeline. The KOBUS KPP series comprises two device types: KPP 300 – This machine is a stand-alone solution for independent handling, modular in design and powered by a separate hydraulic power unit. The maximum tensile force is 100 kN and therefore allows for a range of applications for shorter distances and smaller diameters. The modular design also allows for use in areas with limited accessibility (e.g. gardens and buildings) and transport in a box truck or flatbed truck. KPP 400 – The Pipe Puller is the all-in-one version as an attachment for the mini excavator from the 1.6 t class. It is driven via the auxiliary hydraulics, safely from the driver’s seat. The maximum tensile force is 200 kN and allows for the full range of applications. The drive via the mini excavator reduces the investment volume and avoids additional aggregates on site. The transport takes place on the trailer of the mini excavator or on the loading area
