Product Details
Hydraulic Surface Down-The-Hole Separated (DTH) Drilling Rig For
Open-Pit Mining
Product Overview
The RCZ420T hydraulic DTH drilling rig is equipped with a
dual-motor rotary drill head and a multi-way adjustable rotary
speed valve.
With a rotation torque of up to 3200N·m, it meets the high drilling
requirements for large 76mm drill rods and 138mm drill diameters.
It has a 3m propulsion length, enabling wider and deeper drilling
operations.
Featuring construction-grade crawlers, a piston motor, and a
leveling function, it has better climbing capacity and off-road
performance. The 420 model can adapt to more complex construction
site conditions.
It can drill vertical holes on sloped surfaces, meeting different
construction requirements.
