The ZJ50L 1500HP skid-mounted land rig is engineered with a chain-driven system powered by a “diesel engine + hydraulic coupling + chain compound transmission,” optimizing power utilization for various drilling operations. Its modular design allows for easy assembly and disassembly, making it ideal for different drilling environments.
This rig features a drawworks with internal and external speed shifting, with the ability to switch gears using a coaxial pneumatic clutch, providing convenience and precision in operation. The main brake options include a hydraulic disc brake or a band brake, while the auxiliary brake utilizes an eddy brake for enhanced control.
The ZJ50L is also equipped with a crown block, traveling block, and swivel, all designed to meet the rigorous demands of deep drilling. The rig’s mast and skid-mounted substructure are designed for stability and ease of transport, ensuring that the rig can be quickly and safely deployed.
With its capacity to support a drilling depth of up to 5000 meters, the ZJ50L is an excellent choice for onshore drilling operations requiring reliability, efficiency, and high power.
