ater-lifting device in Pakistan
This construction is a copy of the former made in wood. If we compare different methods of harnessing to this sort of device, the solution from Pakistan is the best one. Here a zebu-ox is fitted with a pad, which distributes the force to the shoulders of the ox. From here, the pull goes down at an angle and then horizontally. The zebu is a powerful animal, which can walk quite fast. It is my impression that this device has an output of about 150 watt.
