water well drilling rig 

GK-400 Drilling Rig is a new type of vertical spindle machine manufactured by Jing Di, for which a diesel engine or motor may be chosen as power. It is primarily used with diamond drill bit or carbide drill bit for the drilling in solid mineral deposit as well as those in engineering geotectonic survey, foundation pile hole and water well hole.

1. Compact mechanical transmission structure, lightweight, vertical spindle for large through hole diameter with hexagonal drive drilling rod, ensured torque transmission.

2. Higher rotating speed and rational scope, adaptable for the drillings with small diameter diamond drill bit or large diameter carbide drill bit and other engineering hole drillings.

3. During the hydraulic controlled feeding process, both the pressure and speed of feeding can be regulated to meet the requirements of different stratum drillings.

4. Less and centralized handles, easy operation.
