Bucket 提桶与提篮装置涉及到加快满水、提水和倒空水桶（或水篮）的过程。这些打水方法技术含量很低，其中一些已沿用了好几百年。Bucket and basket lifting involves speeding up the process of filling, lifting and emptying a bucket (or basket). Several of these very low-tech solutions for lifting water have been around for centuries. There are many pumps that work faster with less effort, but are more costly. So these water lifting devices are good to know about in case better technologies cannot be acquired or breakdown.
