Abstract: A hollow crane spreader beam incorporates at least one radio-controlled load-release assemblies. Each assembly includes a slidable bolt that is coupled to the plunger of an electric-motor-driven, radio-controlled door lock unit that is installed within the beam. When in a first position, taken in response to application of first polarity voltage to the door lock motor, the bolt traps a free end of a load-supporting chain or cable between a pair of eye blocks, each having an aperture through which the bolt slides. When in a second position, taken in response to application of a second polarity voltage, the bolt releases the free end. The spreader beam also incorporates a radio receiver/controller unit and a battery that is coupled to both the radio receiver/controller unit and the multiple door lock units.
