三脚架钻井机是一种手钻的方式，它包含重型三脚架、绞车和工作台。这种方式在津巴布韦和非洲撒哈拉以南地区广泛使用。切削刀具（钻头）通过旋转钻入地下，然后抽出并去除挖出物。重复操作直到达到了理想的深度。
三脚架钻井机在80年代初期被发明，并在津巴布韦进行制造。
适宜条件
三脚架钻井机适合疏松地层，如泥沙和软土。而硬土、硬材料和砂砾不容易或不可能凿穿或移动（除非联合使用螺旋钻和冲击钻).
| 优势 | 劣势 |
|---|---|
| - 能保证垂直钻井 |
- 使用的工具比传统的手钻工具更贵 - 比其他方法更慢 |
修建、运作和维护
三脚架钻井机使用三脚架和工作台，因此比传统的工具更贵，但同时也能保证垂直钻井。
设备由津巴布韦的V&W公司生产。也可以在当地生产。
