    ① High Efficiency and Energy Saving: The top drive is highly efficient and energy-saving, making it very suitable for the future green and low-carbon development direction of drilling equipment.

    ② Reliable Performance: Adopting electric direct drive technology, the internal structure of the top drive housing is made as simple as possible, avoiding major repairs due to small gear or bearing failures, maximizing the reliability and continuous operation capability of the top drive.

    ③ Convenient Maintenance: Traditional mechanical top drive gear meshing generates metal debris that can contaminate the lubricating oil. This top drive has no gear reduction mechanism and uses oil immersion lubrication, which can effectively extend the service life of the lubricating oil and reduce the frequency of oil changes.

    ④ Strong Targeting: Fully meets the needs of wireline core drilling rigs, with a high-speed low-torque design suitable for deep hole core drilling.
