Doosan and Geax Partnership for compact drilling machines

The partnership between Doosan and Geax, an international leader in the design and construction of drilling machines based in Montefano (MC) in Italy, continues to flourish. Formed in 2006, Geax is the brainchild of Ing. Adriano Pesaresi, who after 20 years of experience as a designer in this sector, wanted to establish a new business with the aim of producing innovative and compact drilling machines, offering very high performance, thanks to the fact that they are based on excavators.

In 2019, difficulties in procurement from regular suppliers prompted Geax to look for a new partner able to support the company globally. Geax's choice fell on Doosan for the supply of excavators from 6- to 24-tonne (comprising the DX63, DX140LC, DX180LC, DX210LC and DX225LC base models), built with Stage 5, Stage 4 EPA and Tier 3 engines, so that they can be sold in markets in Italy and Europe, the Americas and the Middle East and Asia.

The excavators are supplied by Doosan without their booms and are transformed by Geax into drilling machines used to produce foundation piles up to 30m in depth and with diameters up to 1.5m. These complex drilling rigs are rigorously built in Italy, at the Geax headquarters in Montefano. The machines are then completely re-certified and distributed by the company all over the world.

The use of Doosan excavators as the base for the drilling machines has the advantage of being able to use the engine, cab, tracks and hydraulic system that guarantees maximum reliability, strength, very high performance and ensures superior quality in terms of ergonomics, comfort and noise. Furthermore, Doosan is able to guarantee an excellent and widespread support service, thanks to its global distribution network, which is able to intervene for any need for normal and extraordinary maintenance, repair and warranty requirements.

These compact drilling machines also offer the important advantage of being able to be transported easily without special permits and can work where other machines for large diameter piles cannot work, such as in confined spaces, on slopes, inside buildings and close to power lines. These machines have proved to be very successful in big cities such as Los Angeles, Sidney and Seattle, where every centimetre has an important cost, and it is particularly profitable to carry out construction works in small spaces, avoiding wasting time and resources through the use of oversized machines.

The biggest markets for Geax compact drilling machines are mainly Italy and the United States, but demand is also increasing in Australia, the UK, France, Germany and the Middle and Far East. Geax took delivery of the first Doosan base machines in 2020, and the first completed drilling machines incorporating them were sold in 2021. To date, about 80 Doosan-based machines have been built, of which over 60 have been purchased and delivered all over the world.
