Impact resistance ZOOMLION ZR280C Rotary Drilling Rig

Stable structure and strong rock penetration ability

Adopting a double large triangular back variable amplitude mast, balancing the high stability of hard rock operations and the transportation advantages of the mast folding machine; Large section mast, large diameter slewing support+reinforced low center of gravity chassis, good anti overturning performance during operation, minimal mast deformation, and high verticality of drilled holes. Three speed reducer power head with sufficient torque reserve, capable of handling soil layers, sand layers, and strongly/moderately weathered rocks, suitable for bridge, building, and municipal pile foundation engineering.

Power hydraulic system, high construction efficiency

Equipped with power matching and ultimate load control technology, multiple power heads and dual speed pressurized oil cylinders, it can switch between low-speed high torque rock entry and high-speed soil throwing modes as needed; Mid mounted single row rope main winch, single-layer steel wire rope design, high lifting force, longer service life of steel wire rope, and reduced consumable costs.

Convenient transition and low transportation costs

The mast can be folded backwards, supporting the transportation of the whole machine without the need to split the mast; Equipped with lifting legs, quick disassembly and assembly, reducing trailer and disassembly time, and saving money on cross site transitions, suitable for projects that require frequent relocation.
