The cargo spreader bar (100) is a rectangular frame with longitudinal sides (120) that are longer than the lateral sides (118e). Hooks (102) are attached to the frame along the longitudinal sides (120). The hooks (102) hold cargo hoisting chains (CH) and include actuator (206) controlled, pivoting safety locks (208) that close to secure the chains (CH) to the hooks (102). A tubular chain lifter (104) pivotally mounted to the frame extends along one of the longitudinal frame members (120). A second chain lifter (104) extends along the remaining longitudinal frame member (120). Inside sections of the tubular chain lifters (104) are pivotally coupled to a chain lifter actuator (400). When safety locks (208) are disengaged, an actuator arm (401) can be commanded to pivot the outside sections of the lifters (104) to swing upward to release the chains (CH) from the hooks (102).
