The Yongan Machinery YZ-300L Hydraulic Vibratory Hammer is equipped with original German-imported FAG high-speed heavy-duty bearings and adopts a dual lubrication system. It uses key components such as Parker motors, Rexroth hydraulic systems, and imported damping rubber. The gearbox internally uses FAG high-speed heavy-duty bearings and adopts a forced and splash dual lubrication system, featuring high vibration frequency, low noise, and increased pile driving and extraction force. It is suitable for steel sheet piles, steel pipe piles, H-piles, and precast pipe piles.
