HW surface down-the-hole (DTH) rig offers high maneuverability, a smaller footprint and the ability to serve multiple locations.
Equipped with a powerful DTH hammer, this rig is designed for high volume rock drilling in quarries, open pit mines and rock excavation projects.
Main feature:
Robust yet compact design provides it with better manoeuvrability in tight corners and higher spacing – burden range.
The rig is equipped with dry dust collector, drill pipe changer, and adopts the most advanced design and layout.
The drilling on the rock is mainly based on the down-the-hole hammer drilling process. The down-the-hole hammer rock drilling operation efficiency is high, and the drilling cost per meter is lower.
