The ZJ30J 750HP land rig is an advanced drilling solution optimized for onshore applications, capable of handling drilling depths from 1500 to 3000 meters (4921 to 9843 feet) depending on the drill pipe size. Powered by a diesel engine coupled with a reduction gearbox and narrow V-belt transmission, the rig offers efficient power distribution and high power utilization, making it well-suited for various drilling conditions.
The drawworks is designed with both internal and external speed shifts, offering a 3F+1R speed configuration, and is operated via a pneumatic remote control for seamless gear changes. The braking system features a primary hydraulic disc brake or band brake, supplemented by an eddy current brake for enhanced safety and control.
Modular design and advanced technology allow for easy assembly, disassembly, and transportation, making the ZJ30J a versatile choice for drilling projects. The rig is also equipped with independent driller’s cabins, offering integrated control of pneumatic, electric, and hydraulic systems, improving the working environment and reducing operator fatigue.
