The invention discloses a hanging hook attitude detection device and a crane with the same. The disclosed hanging hook attitude detection device comprises an angle measuring instrument, an acceleration measuring meter, a processor and an output device, wherein the angle measuring instrument is used for acquiring an inclined angle between a coordinate axes in a second coordinate system and a coordinate axes corresponding to the coordinate axes in the second coordinate system in a first coordinate system; the acceleration measuring meter is used for acquiring the acceleration in a preset direction; the processor is used for establishing the first coordinate system and the second coordinate system; the first coordinate system is fixed opposite to the preset position; the second coordinate system is fixed with a hanging hook; and the processor acquires a attitude parameter of the hanging hook in the first coordinate system according to the inclined angle acquired by the angle measuring instrument and the acceleration acquired by the acceleration measuring meter. The hanging hook attitude detection device can provide the attitude parameter of the hanging hook, enables an operator to take proper hook-stabilizing measures according to the attitude parameter, further reduces adverse influence on the hoisting operation because of the swing of the hanging hook, and improves the efficiency of the hoisting operation.
