JKS600B crawler mounted versatile well drilling rig is a new, efficient and multifunctional drill rig, mainly applicable to the drilling process of wells, monitor boreholes, dewatering boreholes, relief boreholes and gas layers and other exploitation projects. When drilling in the rock layer, the rig adopts DTH percussive hammer for penetration and compressed air for cleaning, the penetration speed being dozens of times quicker than conventional rotation rigs. In loose rock, the rig employs a cutting bit or cone bit and uses mud to clean the dirt, its versatility suiting for all kinds of complex geological conditions. Its versatility makes the rig suitable to various kinds of rigs.
