秋千汲水篮由廉价的材料制成,如,竹条、皮革或铁片,并用四条绳子系住。需要两人面对面拉着篮子浸入地表水中,再将篮子拉起并倒入灌溉渠,流入田中。这是一项重体力活,采用的动作姿势较特别。但也可由家庭中的妇女和孩子操作。操作频率约为15至20提/分钟。提水装置可在最深为1.2米处运作。在0.75米深处流速可特别达到60至80升/分钟。

适宜条件

秋千汲水篮在印度和孟加拉国普遍使用。


优势 不足
- Simple, inexpensive technology which can be locally made and maintained 技术简易、廉价,可在当地制作与维护

- Easy to operate by both adults and children操作简易,成人及儿童均可操作

- Limited to lifts of less than 1.2 m 最高提升1.2米

- Limited water yield 60-80 l/min suitable for small fields出水量最大为60-80升/分钟,适用于小型农田
- Low efficiency (10-15%), big human effort with significant water spillage 低效率(10-15%),重体力,且水会溢出
