Two shoulder harnesses are made from a pair of elongate flexible straps, each of which has a pair of like shoulder-engagable loops formed on opposite ends thereof and connected by a central section of the associated strap. One strap has formed in its central section, which is longer than that of the other strap, a plurality of spaced openings in one of which the other strap is releasably and slidably connected intermediate its ends. In use the interconnected center sections of the straps are positioned beneath a load that can then be lifted by the operators wearing the respective shoulder harnesses. The overall length of the load-bearing sections can be adjusted by inserting the other strap through a different opening in the one strap.
