Introductions

Exploration and Coring Drill Rig, Type HT-260 is a medium deep hole drill rig mainly used in geological survey, small scale water well drilling and constructions of buildings, highways, railways, hydropower power stations, harbors as well as shallow core drilling. It has small size and easy to be dismantled into 4 parts. Hence, it is convenient to be transported and relocated which is conducive for construction works in the mountainous areas and tunnels.
