The AC variable frequency electric drive drilling rigs include specifications such as ZJ30/1700DB, ZJ40/2250DB, ZJ50/3150DB, and ZJ70/4500DB.

Technical Features

The intelligent driller control of the drilling rig is achieved through PLC, and data storage, printing, and remote transmission can also be realized.

Driven by a wide-frequency high-power motor, it achieves stepless speed regulation throughout the entire process of the winch, rotary table, and mud pump;

The brake system, combining hydraulic disc brakes with motor energy-consuming braking, ensures reliable performance;

Intelligentized traveling crane prevents "collision from above and smashing from below";

Real-time monitoring of automatic drill feed, tripping, and drilling conditions;

It can meet the requirements for migration between well locations during cluster drilling;

Protection and monitoring of the MCC system;
