Equipment is commercially produced in western countries. Local production is possible. Percussion drilling is hard work. Use of a small engine may be appropriate. 钻井设备在西方国家中进行商业化生产。当地产品亦可使用。冲击钻井是一种繁重的工作。可能需要适度使用小型发动机。
The percussion drill can be powered by hand, with several men pulling on a rope to lift and drop the bit, or it can harness the power of an engine. It can take the form of a few pieces that can be transported in the trunk of a car and carried into remote villages, or it can be mounted on the bed of a truck and driven to the drill site. The drill parts can be bought from the numerous world-wide companies that make drilling tools or they can be made from readily available scrap steel and local materials. 冲击钻井可手工提供动力,由若干人拉绳来升降钻头,或由发动机来提供动力。可以将钻井工具拆分成几部分,便于放入汽车后备箱载入偏远的村庄,或架在卡车车厢上开往钻井现场。钻具零件可从全球多家钻具公司购得,或可用已有的废钢和当地材料制得。
