In an independent test of the three leading manufacturers of industrial lifting clamps, J.C. Renfroe proved to be the most durable in the category of horizontal lifting. Rexnord Innovation Center (RIC) is an independent, accredited laboratory that has provided confidential testing, analysis and engineering services for over 30 years. The company performed fatigue testing on three manufacturers’ vertical, 180 degree turn + side pull clamps in the horizontal orientation. The tests were conducted from July to August of 2015.
The horizontal test was performed at the +100/+1, 102-pound load level and run one million cycles or until sample failure. Company Number One completed 159,672 cycles before experiencing a crack at the bail pin. Company Number Two completed 79,352 cycles before experiencing a crack at the bail pin. Renfroe’s clamp completed 1,664,928 cycles before a crack appeared at the bail pin.
“This latest test just reconfirms that Renfroe is maintaining its level of durable, reliable clamps,” reports Darrin Noe, Renfroe’s Division Sales Manager. “The company has been producing clamps for over 70 years, and evidently, we haven’t had a slack in quality yet!”
The Renfroe clamp that was tested was one of the new L series clamps, the LPA model, used for vertical lifts. Renfroe offers several clamps designed for vertical 180 degree turn and 90 degree turn.
