Likelihood of Entanglement when Materials are Dropped Vertically onto a Rotating PTO Knuckle.

摘要: Power take-off (PTO) is a common method of transferring power from tractor to towed piece machinery. The PTO also well-documented cause severe and often permanent disabling injuries farm operators. physical conditions that entanglements are not well established. Several studies have explored the parameters as materials been drawn across rotating knuckle test for entanglement probability. objective this study was determine probability when dropped vertically onto spinning at 540 rpm. A total 360 randomized trials were conducted with ten replications each six positions (center yoke, edge yoke downward, upward, center cross, cross upward) different (woven cotton athletic shoe lace, workboot leather twine, denim strip, Tyvek strip). Not single recorded. Dramatic high-speed video imagery authenticated material's motion path it interacted knuckle.
