  • Product Description
  • Structural Characteristics

    ★ Uses "L-type mechanical drive drilling rig" and "J-type mechanical drive drilling rig" to meet different drilling conditions. The power distribution is reasonable, and the power utilization rate is high.

    ★ The winch has two forms: internal speed change and external speed change. For rigs over 2000m, the winch shifting uses a coaxial clutch with pneumatic remote control, making operation convenient. The main brake uses a belt brake or hydraulic disc brake, while the auxiliary brake uses an electromagnetic eddy current brake.

    ★ For rigs over 4000m, the main machine adopts a "high front and low rear" layout, with the power and transmission system installed at a low position, transmitting power to the drilling platform to drive the turntable and cathead winch through a bevel gear box and universal shaft.

    ★ Equipped with a sand retrieval drum, mechanical friction cathead, and turntable drive device.

    ★ Can be equipped with an independent drilling control room. Gas, electricity, liquid control, and drilling instruments are uniformly arranged, allowing the driller to complete all operations from within the room.

    ★ Can be equipped with an independent motor automatic drilling system.

    ★ Can be equipped with a top drive drilling device.
