Abstract
A spread bar device is used to suspend a load from a crane using a lifting harness having a plurality of attachment cables. The spread bar device includes a modular central beam structure assembled from a main beam section and interchangeable end beam sections that are releasably coupled at opposing ends of the main beam section to vary the length of the spread bar device according to the load. One or more truss frames protrude laterally outward from the central beam structure to provide lateral stiffening to ensure sufficient strength while minimizing weight of the spread bar, despite the modular construction of the central beam assembly.
