THE MADDOCK STORY
100+ Years of Equipping the People Who Build and Maintain Our Communities
The Maddock family’s roots in heavy equipment reach back to 1917. Across five generations, the equipment has changed and the business has evolved, but the focus has remained remarkably consistent: understand the work, provide the right equipment, and take care of the customer.
CLEVELAND, OHIO | 1917
Where It Started
In 1917, William F. Maddock founded the Day & Maddock Company in Cleveland, Ohio. It was the first construction and industrial equipment distributing organization established in Northern Ohio.
The company supplied construction contractors with heavy equipment through sales, rentals, and leasing. Over the years, Day & Maddock built a large and diverse equipment fleet and supplied machinery used on construction projects around the country.
Roads, power plants, buildings, and other major projects were built with equipment supplied and supported by Day & Maddock.
THE MADDOCK STORY
More Than a Century in Machinery
From Cleveland in 1917 to Tucson today, the Maddock story has followed generations of a family working with machinery and the people who depend on it.
TUCSON, ARIZONA | 1974
A New Chapter in Arizona
In 1974, Maddock Machinery Corporation opened in Tucson at a small location on N. Stone Avenue near downtown.
With a staff of two, the company served customers including Mountain Bell and Pepsi, providing fleet service and aerial equipment repair.
As customer needs changed, Maddock Machinery changed with them. In the early 1990s, Bill Maddock expanded the business into fleet equipment upfitting, bringing Knapheide Manufacturing, Anthony Liftgates, and Liftmoore Cranes to the Tucson market.
That expansion helped shape the Maddock Machinery we know today.
The Equipment Changes. The Work Continues.
The equipment looks very different today than it did in 1917, but the formula for success is familiar.
Understand the customer’s needs. Find the right solution. Build it. Maintain it. Keep the people who depend on it working.
THE NEXT GENERATION
Five Generations in Machinery
What started with William F. Maddock in Cleveland has continued across five generations of the Maddock family.
Today, that family history is part of a business that has spent more than 50 years serving Arizona customers and more than a century learning what it means to stand behind the equipment people depend on.
