Explorac 235 Walkaround

Lennart Johansson, Global Product Manager for the Explorac range, guides you through the main benefits and features of the Explorac 235


Leading the way

Explorac 235 is the most modern and user friendly rig on the market, designed in cooperation with exploration professionals. Every component has been carefully designed to provide excellent drilling results and to meet demands from contractors, miners and geologists.

Safe and ergonomic

Safe and user-friendly rod handling is available from a rack, a supply truck or the ground. Other safety features in¬clude radio-controlled tramming and a safety cage preventing operators from being close to turning items.


The integrated cyclone and sample collection system allows continuous, dust-free sampling with little or no pause in the drilling process. Thanks to the rod handler, one person is sufficient to automatically handle the rods as quickly as using manual handling.

Product description

The Explorac 235 meets all the challenges of exploration with reverse circulation. While designed specifically for reverse circulation drilling to depths of 300–400 meters, the rig can be easily adapted for water well drilling. The Explorac 235 is available for assembly on a truck or crawler chassis.
