Specifications and Capabilities
The SQ100J Down-the-Hole (DTH) drilling rig is a compact, mobile solution designed for shallow to medium-depth borehole drilling. With a hole diameter range of 90–120 mm and a total machine weight of approximately 5.65 tons, it is well-suited for applications in geotechnical surveys, water well drilling, and small-scale mining.
While detailed manufacturer documentation is scarce, similar rigs such as the HQJ100A from Shanghai Newton Machinery and Lead Group Co., Ltd. offer comparable specs:
Manufacturing Landscape in China
China’s drilling rig industry is vast and competitive, with manufacturers like Sunward, Hanfa, and Lead Group offering a wide range of DTH rigs. Many of these companies provide OEM and ODM services, allowing customization based on terrain, depth, and drilling method.
For example, Sunward’s SWDE165B and SWDE200B models are designed for surface drilling and offer advanced features like automated rod handling and real-time drilling data feedback, which are increasingly in demand for precision projects.
Field Use and Anecdotes
In Pakistan’s Balochistan region, a contractor used a Chinese DTH rig similar to the SQ100J to drill exploratory wells for a rural water supply project. Despite rocky terrain and limited access to spare parts, the rig completed over 40 boreholes in three months. The operator noted, “It’s not fancy, but it gets the job done—and parts are easier to find than you’d think.”
In another case, a mining team in Mongolia retrofitted a SQ100J-type rig with a custom air compressor to increase penetration rates in basalt formations. The modification improved efficiency by 15%, demonstrating the rig’s adaptability.
Challenges in Sourcing and Support
One of the main hurdles in acquiring rigs like the SQ100J is identifying the original manufacturer. Many units are sold through trading companies or rebranded by regional distributors. Buyers are advised to:
Conclusion: Small Rig, Big Impact
The SQ100J DTH drilling rig exemplifies the rise of cost-effective, versatile drilling solutions from China. While it may lack the polish of Western counterparts, its performance in the field and adaptability make it a valuable asset for contractors working in tough conditions. As global infrastructure needs grow, rigs like the SQ100J will continue to play a vital role in bridging affordability and functionality.
