The John Bean T7100S Tire Changing System, No. T7100S, from Snap-on Equipment, is a center post tire changer designed for easy use with minimal training of technicians. The PROspeed feature provides rotational speed maximized by automatic inverter control with a variable from 7 rpm to 18 rpm. A swing arm style mount/demount provides a quick change design with non-marring plastic and metal mount/demount tools included. An integrated bead pusher assists in the mount/demount process of the upper bead while a tire lifting tool aids the technician with the demounting process. The side-mounted, hand-activated bead breaker is activated by a thumb switch at the point of use. The center post clamp design reduces risk of wheel damage and accommodates a wider range of wheel sizes, according to the company. An integrated roller board eases bead breaking.
