Product Introduction

GMT40S is a large-diameter top hammer surface drilling machine with superior performance and outstanding production capacity. The direct control design ensures the high performance and reliability of the machine. The engine ensures the high efficiency and productivity of the drilling machine. GMT40S is widely used in fields such as limestone mines and aggregate quarries.

GMT40S hydraulic top hammer drilling rig is designed for open pit quarrying and mining projects. It is outfitted with a standard drill rod with a diameter of 45/38 millimeters. It allows for vertical, inclined, and horizontal blast hole drilling with a range of 43-115 millimeters. It has a wide range of applications including excavation, cutting, pipelining, foundation drilling, and open-pit mine drilling.
GMT40S is an equally versatile and efficient down-the-hole drill rig that keeps your production up and your costs down. Thanks to its flexibility and overall drilling capacity, it's just as perfect for quarry blasthole drilling as for mining operations. The precise DTH drilling empowered by our unique cylinder feeding improves blasting, and running at a lower rpm means longer engine life, less fuel consumption, and low lifetime cost.
