WIRTH supplies these drill rigs for special civil engineering in a series with torque levels from 140 - 400 kNm. The machines are mounted on a crawler chassis. Characteristic of all WIRTH rigs is that they can be transported complete with drilling mast. This is an advantage in terms of high mobility and short set-up times. Typical areas of application for these rigs are pile foundations by the dry boring method, the construction of secant pile diaphragm walls, CFA, partial and full displacement boring.
