    QY70K-I(hydraulic control)

    The innovative jib system adopts embedded block, plug-in boom head and international advanced U section jib, which has excellent lifting performance and safe and reliable lifting work.
    • The unique stretch and retract technique avoids the bend of the core pipe and cylinder and the break of the boom caused by misoperation, improving the safety of the operations.
    • Eight patent techniques ensure the smooth, high efficiency and energy conservation of the lifting, rotation, and luffing systems.
    • The torque limiter adopts colorful LCD display, realizing the intelligence of the failure diagnosis. The precision is ahead of the industry.
    • Adopt the new hydraulic motor with big torque starting point, making the secondary lifting safer.
    • The humanity design makes the cab and control cab more spacious, and easy to operate.
    • Six unique manufacturing technologies ensure the high quality.

    • The working condition expands twice. Newly add 5t counterweight.
