JoyRide suspension systems are currently available as an option on all Joy low, mid, and high-seam shuttle car models—with a design under way for ultra-high seam models. Benefits include vibration dampening characteristics that reduce forces on the machine chassis, resulting in less wear and tear on shuttle car components, reduced material loss, and less rutting in roadways. Most importantly, less energy and impact transferred to the operator allows the ability to safely and comfortably maintain higher shuttle car speeds with less fatigue. “As has been proven in suspension cars already operating underground, improved ergonomic performance means more trips per shift, which means more tons per day at a lower cost. This positive affect on operator safety, as well as productivity, is why we are seeing a higher percentage of our customers moving toward the suspension system option,” said Cressman.
The improved JoyRide strut design, which is backward compatible, is the result of ongoing and innovative design initiatives, and meticulous component and underground machine testing, which has ultimately allowed similar advancements in aboveground earth moving equipment suspension systems to be applied to space-efficient underground equipment. “The JoyRide strut design tested favorably against ISO standards for human body vibration exposure. Also, the JoyRide strut is a simple, self-contained unit, and can be retrofitted to suspension machines currently in the field without a new chassis being required,” said Cressman. www.joyglobal.com
