Top hammer drilling rig SWDH89A

Product Introduction

SWDH series fully hydraulic surface top hammer drilling rigs are equipped with high-efficiency hydraulic rock drills with counter-strike function to reduce the risk of sticking. In addition, the power of the rock drill-air compressor-engine equipped with the drilling rig is reasonably matched, which can greatly reduce the fuel consumption. The comprehensive product features are:
1. High-power hydraulic rock drill, with large impact energy and back-strike function, effectively reduces the risk of sticking and saves drilling tools;
2. The core components adopt internationally renowned brands, with good reliability, high operating efficiency and low energy consumption;
3. Rock drill-air compressor-engine benchmark matching, with economical/powerful dual operation mode. Wide adaptability of rock formation and low operating cost;
4. The whole machine has a compact structure, small and flexible, fast walking speed and strong off-road ability;
5. Adopt foldable drill arm. One-time coverage area drilling, suitable for multi-angle control drilling, fast and fast drilling positioning.
