High hole-forming precision Zoomlion ZR280C-3 Rotary Drilling Rig

Super strong rock penetrating ability

A high torque of 280kN · m is paired with a three speed reducer power head, resulting in a high torque reserve coefficient.
Adapt the machine lock rod and rock drilling bit (such as pick cylinder drill, spiral drill), which can efficiently drill into moderately weathered and weakly weathered rock layers.

Top construction stability

The world’s first double large triangular mast variable amplitude structure has stronger rigidity than traditional small triangular masts.
When entering the rock, the vibration is reduced by 10%, the mast deformation is small, and the verticality of the borehole is extremely high.
100 ton heavy-duty chassis with large diameter slewing bearings, strong resistance to torsion and compression.

Efficient and intelligent, faster construction

Using version 2.0 power matching technology, the engine and hydraulic pump are dynamically matched, reducing fuel consumption by about 2%.
Multi speed power head: High speed in soft terrain and high torque in hard terrain, with a 10% increase in overall efficiency.
Equipped with intelligent functions such as one click soil throwing, one click hole scanning, and automatic vehicle display.
