The Dando Drilling International Multitec 4000 with Dando Duplex Drive (3D) system is a small, light, versatile drilling rig on a 1.4-meter-wide crawler unit that is designed to include the features of a much larger rig while maintaining the ability to access tight spaces. The multipurpose machine is capable of drilling to depths of 200 meters and is most relevant to water, mineral, geotechnical and geothermal applications. Its hydraulically deployed 3D percussive hammer can also take undisturbed samples or run tests such as the SPT as required.
