Product Description

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.

Key Features

 

 

  • The dual-motor rotary drill head, with larger torque and higher rotation speed, meets the drilling needs for 76mm drill rods and 130mm drill diameters.
 
  • Construction-grade crawlers and a piston motor ensure more reliable machine performance and better traveling capabilities, allowing it to better adapt to complex ground conditions in surface mining drilling operations.
 
  • The centralized control panel is easy to operate, enhancing the efficiency, safety, and comfort of drilling operations.
 
  • The newly added leveling function gives the machine better climbing capacity and off-road performance, enabling it to handle different construction environments more effectively. The 420 model can also drill vertical holes on sloped surfaces, meeting various construction needs.
 
Applications
 

This RCZ420T hydraulic DTH drilling rig is widely used in open-pit mining blast hole drilling, quarry blast hole drilling, highway blast hole drilling, water conservancy projects, power station construction, railway construction, and other construction drilling operations.
