A crane load centering assembly includes a crane that has a boom, a sheave that is rotatably coupled to the boom and a load block. A transmitting unit is coupled to the sheave having the transmitting unit being directed downwardly from the sheave. The transmitting unit transmits an alignment signal along a line that is vertically oriented. In this way the alignment signal can travel in the direction of the force of gravity with respect to the boom. A plurality of sensors is provided and each of the sensors is coupled to the load block such that each of the sensors is positioned below and is aligned with the transmitting unit. One of the sensors receives the alignment signal when the crane lifts a load and the load deflects from beneath the sheave. A plurality of light emitters is provided and each of the light emitters is coupled to the load block. Each of the light emitters is in electrical communication with a respective one of the sensors and each of the light emitters has one of the sensors associated therewith. Each of the light emitters is turned on when the associated sensor receives the alignment signal to communicate a visual alert for the deflection of the load.
