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.
Swing baskets are popular in India and Bangladesh.
