Multitec 4000 MK3 Multipurpose Rig

Occupying a small footprint, the compact, powerful Multitec 4000 MK3 can perform a wide range of drilling techniques in areas of limited access and difficult terrain.

Suitable for geotechnical, mineral exploration, water well and GSHP drilling applications, the rig is modular and customisable to the customer’s project. It can accommodate a range of engines, pumps, winches, carrier vehicles, and other ancillaries.

The latest MK3 version has more power, a highly efficient Bosch-Rexroth hydraulic system, revised layout of deck components and an improved, lower and more central centre of mass for the ultimate stability in uneven and sloping terrain.

Bolivia - Site Investigation

Purchased by a large electricity provider in Bolivia, the Multitec 4000 MK2 is being used for geotechnical work in Cochabamba, including H wireline coring up to 200m as well as SPTs, shelby tube sampling and lugeon tests. Compact, lightweight and mounted on tracks the rig is ideal for operating in areas of difficult access, for example crossing rough terrain to access river banks.

UK- Domestic GSHP Drilling

The Multitec 4000 MK2 has been drilling two boreholes to 120m for domestic GSHPs (Ground Source Heat Pumps.) The rig's compact design and small footprint made it ideal for this project due to limited space and restricted access to the site.

Kuwait - Site Investigation

Custom built to the customer’s requirements, the two truck mounted rigs are fitted with a large peristaltic Bredel pump capable of pumping very high viscous materials, hydraulic side shift for the rotary head and a hydraulic SPT hammer. These machines are being used for geotechnical drilling in Kuwait.
