Double Triangle Patent Range Zoomlion ZR280 Rotary Drilling Rig

The power head is strong enough to penetrate the rock

Three motor and three reducer power head, multi speed electric torque adjustment, sufficient reserve for drilling in hard rock and gravel layers; Reserved interfaces for pipe rolling machine and casing driver, suitable for complex formations such as karst, quicksand, and rich water.

Double Triangle Patent Range

The inclination angle of the mast support oil cylinder is larger, and it can be completely folded back flat, making it easier to dismantle the mast during transition; During construction, the mast is resistant to deformation, and the verticality error of the drilled hole is ≤ 0.5%. The pressure anti bending device is used to protect the drill rod from bending.

Single layer and single row rope design for main winch

A dual machine structure with a single layer of steel wire rope significantly reduces wear and extends the steel rope replacement cycle; 340kN ultra large lifting force, large single slag removal capacity, construction efficiency increased by more than 10%, with built-in floating anti disorderly rope structure.
