ZOOMLION ZM300H/G is engineered for ultra-large-diameter pile foundation construction. With 13,500 kN·m of rotary torque, this heavy-duty foundation machinery can handle steel casings for borehole diameters ranging from 2,000 to 3,000 mm. The heavy construction machinery addresses this with an impressive 8,450 kN extraction force and a 650 mm push-pull stroke, providing the force needed to advance and retrieve large casings under heavy loads. This full casing drilling rig is suited to major bridge construction, including main pier foundations, and other large-scale infrastructure projects requiring ultra-large-diameter pile foundations.

• Drilling diameter: Ø2000-Ø3000 mm
