The swing basket is made from cheap materials like woven bamboo strips, leather, or iron sheet to which four ropes are attached. Two people hold the basket facing each other, they dip the basket into the surface water and the basket is lifted by swinging it and emptied into an irrigation channel from which point the water flows to the fields. The work demands heavy physical activity, with adoption of awkward body movements and posture. Yet it can also be operated by women and minor members of the family. The frequency of operation is about 15 to 20 swings/minute. This lifter can be used at depths of up to 1.2 m. Typical flow rates of 60 to 80 l/min are obtained at depths of 0.75 m. 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。需要两人面对面拉住篮子,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米深处流速可达60至80升/分钟。

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
