Though small in size, the GM50 is a versatile geotechnical drill rig suitable for all main investigation methods except for casing and core sampling in rock. It has enough power to accommodate percussion drilling for hole-opening purposes. The rig can also be used to install small groundwater pipes in shallow groundwater wells. The compact size of the GM50 drill rig makes it easy to move it from one site to another on a car trailer. It is also easy and fast to get up and running at the site.

GM75 is the most popular of the Geomachine drill rig models. With considerably more power than its little brother, it can easily handle all medium-duty geotechnical investigation methods. GM75 always comes delivered with a fast and versatile chain cylinder boom. It can also be equipped with a hybrid pack that allows drilling without local exhaust emissions.

GM85 is a versatile option for all moderately difficult geotechnical investigation and exploration work. Having more power, it can work faster and go deeper than the smaller options in our range. Available with both a direct cylinder and chain cylinder boom, GM85 can also be equipped with an optional rotary head for core sampling in rock. GM85 is also available as a hybrid.

GM100 is a tireless, efficient and fast workhorse for the most challenging, heavy-duty geotechnical investigations and explorations. It is ideally suited to percussion drilling and the installation of large groundwater pipes. GM100 can be equipped with a direct or chain cylinder boom and various rotary heads to meet the user’s needs. An optional hybrid pack is also available for drilling in urban conditions without producing exhaust emissions.

Geomachine’s GM200GL is the right choice for exploration drilling at sites with difficult access. The rig’s specially designed boom makes it the best tool both for ore sampling from rock surface as well as diamond coring in several hundred meters deep.

Geomachine’s light boom is small in size but still suitable for all main investigation methods except for casing drilling and core sampling in rock. The boom can also be used to install small groundwater pipes in shallow groundwater wells. The light boom comes in two lengths and is the standard boom in the GM50GT drill rig. The boom can also be mounted on other lightweight carriers besides Geomachine rigs.

Chain feed booms offer double the movement speed compared to direct feed booms, making them excellent options for medium-duty geotechnical investigations where drilling speed is the key driver. Chain feed boom is particularly suitable for environments with restrictions on the boom’s operating height, such as railway works and tunnels.
