秋千汲水篮
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。
