In response to customer and market
demand, Alcoa Wheel Products has developed a new wheel for European construction
vehicles with disc brakes. More specifically, this new wheel was designed with
no ventilation holes to help protect the drive/front axle disc brakes from sand
and gravel. Alcoa believes this new design will provide its customers with true
added value through the reduction of maintenance costs, increased brake life,
and improved performance. This wheel is already approved and available on
Mercedes-Benz construction vehicles, but can be mounted on any other truck brand
as well.
WorkHorse® wheels provide a 5% increase in
maximum load as compared to standard wheels in the same sizes. The increase in
maximum load for the 22.5 x 11.75 / 120 mm offset wheel is even 10%. Due to its
new and stronger design, the fatigue life for these new wheels has also been
increased. Mounting characteristics for the WorkHorse® wheel
remain the same as those for standard wheels.
The
WorkHorse® wheel can be used as the inner dual wheel on a
construction vehicle's drive or tag axle, or single on its front axle. See
testimony in our July 2008 newsletter. The 22.5 x
11.75 / 120 mm offset wheel can also be mounted on trailers. See testimony in
our November 2007 newsletter.

wheels are available in the following sizes and fitments:
