JK930 Truck Mounted Water Well Drilling Rig 300m Borehole Mud and DTH Machine

Two Drilling Methods, One Truck

Almost every well starts in soil, clay or gravel and finishes in rock. Buying two rigs for those two jobs is expensive; the JK930 runs both. Mud rotary cuts the overburden and sets surface casing, then the head changes over to a DTH hammer for granite, basalt or hard limestone.

What sits on the chassis

• Oil injected screw compressor, 17-35 m3/min at 1.05-2.5 MPa.
• Onboard mud pump and foam pump for the rotary section.
• 3.5 m feed stroke, 3 m rod sections, 25 t pullback.
• Rotary head 0-80 rpm with 8,000-10,000 N.m torque.

Changeover in half a day

Head, hoses and bit swap on the same mast. That is the reason most buyers choose a dual method machine rather than two separate rigs: one crew, one service schedule, one set of spares.

Well specification

Typical completions sit between 150 mm and 250 mm, leaving room for the pump and riser. Outriggers level the rig, the mast raises hydraulically, and drilling starts without a lowboy or crane on site.

Delivery

Shipped naked on flat rack or by Ro-Ro, delivered 35-55 working days after deposit, with tools and wear parts in export plywood cases.
