The lightest model in our drill range is the two-tonne GM50 . The biggest and toughest model is the GM8, which weighs ten tonnes and moves on eight rubber wheels.
Each of our geotechnical drill rigs is modular in construction and can be customized according to the needs of the user. All models are powered by a diesel engine that meets the latest emission standards and all but the two smallest models can be converted to hybrid power.
Although GM50 is a small geotechnical drill rig, it can be used for all main investigation methods except casing drilling and core sampling in rock.
Due to its limited power, percussion drilling can only be used for hole opening purposes.
Small groundwater pipes can be installed in shallow groundwater wells. GM50 is available with 1,4 m or 2,4 m long boom with one drilling table.
Due to its light weight and small dimensions, GM50 can be transported with a car trailer and is simple to handle on site.
GM65 is a geotechnical drill rig that is available with direct cylinder or chain cylinder boom depending on customer requirements. Both boom types are equipped with two hydraulic drilling tables and have two different rotary head options.
GM65 is capable of all geotechnical investigation methods and even has limited capabilities for core sampling in rock.
GM75 is the most popular geotechnical drill rig model in the Geomachine fleet. In addition to chain cylinder and direct cylinder boom types, Geomachine’s latest boom innovation, Dual Mast, is also available.
GM75 has more power than smaller GM models and the rig can also be used for geological mine exploration using the diamond coring rotator unit.
GM75 can also be ordered with an electric motor as a hybrid.
GM85 is a geotechnical drill rig that is a powerful choice for all moderately difficult investigation and exploration work.
GM85 is the most configurable of GM models and can be equipped with the strongest GM rotation unit available.
GM85 has more power compared to smaller models and therefore works faster and goes deeper. An electric power pack can be attached to GM85.
Geotechnical drill rig GM100 is the heavy-duty workhorse for all geotechnical and geological investigations. The rig can be equipped with a powerful direct or chain cylinder boom. Both boom types have several different rotary head and hammer options, depending on customer requirements.
GM100 is designed for the most challenging geotechnical investigations and geological explorations. It is ideal for casing drilling and installing large ground water pipes.
GM100 can be equipped with a DTH drilling unit and a hybrid pack is also available.
GM200 is the GM100’s big brother and has more size and space ensuring smoother drilling operations. This rig is designed especially for geological investigations i.e. core sampling in rock.
GM200 is also available with a hybrid pack.
GM8 goes where no other geotechnical drill rig can. It is a special 8-wheeled model designed to access sites in the most difficult terrain.
The special carriage is highly configurable and can be fitted with all GM boom types, rotator units and hammers.
All soil investigation and mine exploration methods can be performed with this 10-ton eight wheeled mammoth.
GM Hybrid is the world’s first emission-free alternative for soil investigation.
When a drilling rig is equipped with the hydraulic pack, the rig’s power source can easily be changed from diesel to electric.
Solution is designed for drilling operations without exhaust gases in urban working conditions. It is especially good while working in environments with emission or noise restrictions, as well as indoors.
The GM Hybrid engine pack can be fitted to five different Geomachine rig types GM75, GM85, GM100, GM200 and GM8.
