Proud Tradition of Quality and Service

Maddock Machinery Corporation was founded in 1974 in Tucson at a small location on N. Stone Avenue near the downtown area. Our original staff of two served customers such as Mountain Bell and Pepsi, providing fleet service and aerial equipment repair.

Now, just as it was then, our corporate philosophy is simple:

Eliminate the customer’s vehicle related stress, find new solutions, preserve the customer’s capital, never sacrifice quality.

The customer base grew and in the early 1990s Bill Maddock, our founder, expanded the business to become a fleet equipment upfitter by introducing the Knapheide Manufacturing product line as well as Anthony Liftgates and Liftmoore Cranes to the Tucson market.

Our equipment lines and customer base have continued growing and Maddock Machinery is now the most qualified and comprehensive builder of utility vehicles in the Southwestern United States. From a toolbox installation to the most complex utility line vehicle you can rely on Maddock Machinery to provide the right equipment, professionally specified and expertly installed.
