DQ40BZ01-YM Oil Top Drive

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 Silent and environmentally friendly: The gearless reducer and lubrication oil pump operate with low noise; it also uses closed water cooling and hydraulic station placement technology, ensuring that the working noise does not exceed 50 decibels, significantly improving the working environment for workers.
③ Completely explosion-proof: The main motor of the top drive uses closed water cooling technology, and the main motor is sealed inside the top drive body, achieving a truly complete explosion-proof function.

    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 Silent and Environmentally Friendly: The gearbox and lubrication pump operate with low noise; it also uses closed water cooling and hydraulic station lower placement technology, with working noise not exceeding 50 decibels, significantly improving the working environment for workers.

    ③ Completely Explosion-Proof: The main motor of the top drive uses closed water cooling technology, and the main motor is sealed inside the top drive body, achieving true complete explosion-proof functionality.

    ④ Reliable Performance: The use of electric direct drive technology aims to simplify the internal structure of the top drive casing, avoiding major repairs due to small gear or bearing failures, maximizing the reliability and continuous operation capability of the top drive.

    ⑤ Convenient Maintenance: Traditional mechanical top drive gear meshing generates metal debris that can contaminate the lubrication oil; the DQZ series top drive uses a gearless reduction mechanism with oil immersion lubrication, effectively extending the service life of the lubrication oil and reducing the frequency of oil changes.

    ⑥ Precise Control: When the top drive is performing directional inclination or after activating the torque swing reduction function, it requires precise control of the spindle rotation angle and direction.
