The present invention provides a detecting and monitoring device of the hook angle and its crane; a preferred embodiment thereof is to lengthen the two side-fenders of a movable pulley of the crane raising pulley assembly by equal amounts so that a platform can be fixed on the vacant space between the inner sides of the lengthened fenders. The platform is installed in such a way that the platform surface is a horizontal plane when the hook deviation angle is 0 degree. An angle measuring instrument is disposed on the platform surface and used to detect hook angle in real-time. The hook angle is shown in crane operator's cab by a wireless transmitter to control the crane, eliminate the hook angle deviation, and provide the basis of the vertical lifting. The embodiment can be applied to stand-alone lifting, double machine hoisting, or main and auxiliary machine hoisting. The device can be suitably installed on mobile cranes.
