Hunter debuts Auto28 tire changer

Dec. 2, 2010

Hunter Engineering Co.’s new Auto28 tire changer services all wheel designs from 10 to 28 inches in diameter safely and easily, the company says.

The Auto28 features a tool head design that automatically slips easily between the rim edge and tire sidewall and extracts the bead gently in one fluid down-and-up motion without the use of bead levers. This leverless system reduces potentially damaging stress on the bead and eases overall operation, Hunter notes. 

The powerful, high-torque electric motor exerts over 850 ft.-lbs. of torque to mount even the most stubborn beads. The variable-speed drive system gives the technician the ability to control the amount of force needed to service a wheel at the most efficient speed, while safeguarding against damage.

The center-support clamping table and self-centering quick clamp give the Auto28 the flexibility to easily mount a wide variety of wheel designs with the same clamping technique. The cam action of the clamping support multiplies the clamping force, automatically immobilizing the rim during mounting and demounting operations to prevent slippage.

The mount/demount rollers gently roll the tire off or on the rim under complete command of the operator. The rollers are also strong enough to hold the tire stationary while the rim is rotated to complete match-mounting procedures.

The bead press arm works with the bead rollers for faster mounting of difficult tires, says Hunter. The bead press arm pushes and holds stiff sidewalls in the drop-center of a rim as the wheel rotates, greatly reducing the risk of bead damage.

Tool head, bead roller and clamping table operations use simple controls that are easy to learn and promote fast, efficient service. A simple control pendent and single foot pedal control virtually all tire changing operations, ensuring the same operation on all wheels regardless of the size, design or fitment.

The Auto28 also features a side-mounted bead loosener using a side-shovel design familiar to most technicians and an optional wheel lift to help with heavy or expensive wheel assemblies.
