After the workers at the bottom of the well load the excavated earth and stone into the hanging bucket or hanging bag, it is lifted out of the wellhead by the winch and suspended in the middle of the derrick. Then, the workers above the well lean their bodies towards the derrick, hold the derrick with one hand, and reach towards the middle of the wellhead with the other hand to lift the hanging bucket or hanging bag suspended on the derrick out of the derrick. After unloading the earth and stone, the hanging bucket or hanging bag is hung on the hook 16 again and lowered to the bottom of the well by the winch, and so on for cyclic operation.
