The invention relates to a crane weight sensor, which comprises a hoisting wire rope, a pulley bracket and an adjusting bolt with a handle, wherein a pulley shaft assembly is arranged at one end of the pulley bracket; a pulley bracket long hole is formed in the other end of the pulley bracket; a sensor pulley is arranged on the pulley shaft assembly; the hoisting wire rope is adjacent to and connected with the sensor pulley through an external ditch edge of the sensor pulley; the weight sensor is arranged in the middle of the pulley bracket; the adjusting bolt with the handle is connected with the pulley bracket long hole; and a sensor mounting frame is fixed at the tail end of the adjusting bolt with the handle through a clamp nut. The adjusting rod type hoist weight sensor can transmit the weight that a hoisting hook of the hoist hoists a heavy to the weight sensor fixed by an adjusting lever through the gravity action of the hoisting wire rope on the sensor pulley, so that the weight sensor deforms and outputs to an analogue value sensor corresponding to the weight value.
