MADISON, Ind. — Rotary has introduced a new line of heavy-duty tire changers to help technicians change tires on trucks, buses, and other vehicles in the shop or on the road.

Rotary offers three heavy-duty tire changer models:

• The R501N Speed Changer HD can dismount and mount a truck tire in 30 seconds, according to Rotary. It is equipped with four rollers positioned on both sides of the wheel in diametrically opposite positions. Rotary said that the R501N’s compact design is ideal for truck tires, bus tires, and super singles. Maximum tire width is 21 inches, and maximum diameter is 52 inches.

• The R560 Mobile HD is designed for both roadside and workshop service, suitable for closed vans or small workshops. The standard roller can be used for tube tires, and the hydraulic clamping and table top are suitable for agricultural tires. Maximum tire width is 37.4 inches, and maximum diameter is 51 inches.

• The R511 Commercial HD can service the widest range of wheels, including truck, bus, super single, lock ring, and agricultural. The controls, which have lever-type hydraulic distributors, enable the user to regulate the speed of the tool holding the carriage. Maximum tire width is 36.4 inches, and maximum diameter is 64 inches.

“Whether you’re changing tires in the shop or on the road, on a bus, truck, or tractor, Rotary has a heavy-duty tire changer that will help you get the job done quickly on nearly any size wheel,” said Rob Dabrowski, vice president of wheel service equipment for Rotary parent company Vehicle Service Group.
