ABSTRACT:
A draw bar sling for lifting heavy loads such as railroad cars includes a lightweight rigid U-shaped saddle made, for example, of an aluminum alloy, having a central shelf for engaging the coupler tongue of the car and a concave passageway extending under the central section. A loop sling comprising a core bundle of high performance fibers, encased in a tubular abrasion resistant covering, extends in through the passageway to form two closed curve eye sections above the saddle through which a crane hook can be inserted to lift the coupler tongue. A cut proof sleeve surrounds each eye section to prevent the hook from cutting the high performance fibers. The cut proof sleeve comprises multiple layers of high performance fibers, and particularly Spectra, woven at right angles and sewn between sheets of abrasion resistant material.
