Product Features

JKS400SHis a new, efficient, multifunctional hydraulic crawler mounted telescoping mast well drilling rig, mainly applicable to the drilling process of water well, monitoring boreholes and geothermal boreholes. 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. 

The rig is able to handle casing size up to 6 meters.

In loose rock, the rig employs a cutting bit or cone bit and uses mud to bring out the cuttings, its versatility suiting for all kinds of complex geological conditions

Hydraulic supporters used facilitate the rig erection on site without crane.
