Abstract A safety pick-up sling for handling tubular goods including a formed saddle having an arcuate recess to engage the tubular goods and having a steel cable secured centrally to the top of the saddle and extending twice beneath the saddle to encompass the goods. The steel cable has its opposite free ends secured to an equalizing lifting ring for attachment to a lifting cable. The lifting action of the lifting cable on the equalizing ring tightens the cable to the saddle to hold the tubular goods therein.
