The invention provides a crown block, an encoder calibration method thereof and a crown block based on encoder positioning, the crown block comprises a roller, a height limiter, an encoder and a controller, the height limiter is connected to the roller through an extension shaft; the encoder is arranged on the extension shaft, is coaxial with the roller and the height limiter, synchronously rotates with the roller and the height limiter, and is used for acquiring rotating speed information, position information and/or angle information of the roller; the controller is in signal connection with the height limiting stopper and the encoder, and under the condition that the height limiting stopper triggers a limiting signal, the controller responds to the limiting signal and sends a zero setting signal to the encoder, so that the encoder is reset. According to the technical scheme, the accuracy of the hoisting height of the crown block can be improved.
