Engineered for foundation construction, the HPR38-20 is a compact, high-performance mini drilling rig built to excel in confined, low-clearance environments—from under bridges and power lines to indoor construction sites, with zero access barriers.
HPR35A Mini rotary drilling rig offers low clearance and lightweight construction as its core advantages, making it ideal for confined working environments and complex site access requirements.
HPR45-16 mini rotary drilling rig has a maximum drilling depth of 16 metres, with a drilling diameter range of 300 to 1000 millimetres. The machine weighs 12,000 kilograms.
The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug.로터리 드릴링 장비는 샤프트를 회전시키고 양압을 가하여 로터리 드릴링 비트가 암석에 충격을 가하고 구르고 전단할 수 있도록 구동합니다. 암석을 분쇄하여 분쇄 링 영역을 형성한 다음 샤프트의 스윙으로 중간 기둥을 부수고 부러진 기둥을 꺼내 구멍을 만듭니다.
