The JKS300B is a new-generation efficient hydraulic well drilling rig engineered for water well, monitor well and geothermal well drilling. Its compact footprint allows the machine to access narrow job sites where larger rigs cannot operate, while the crawler chassis delivers reliable traction on soft or uneven ground.

Dual Drilling Modes for Complex Geology

In hard rock formations, the rig switches to DTH hammer mode with compressed air flushing, achieving penetration speeds several times faster than conventional rotary drilling. In loose or soft strata, it uses cutting bits or cone bits with mud circulation, giving the operator full flexibility across changing ground conditions.

Field-Friendly Design

Hydraulic supporting legs allow the rig to be leveled and erected on site without a crane.
Built-in winch lifts drill pipes up to 6 m, speeding up pipe handling.
Stepless variable rotation speed (0-40/80 rpm) via high-pressure variable pump simplifies the drive train and reduces weight.
Optional 24kW/380V hydraulic generator and foam pump expand job-site capability.
