The immense
popularity of Ford's Model T automobile led to the creation of a
diverse industry of aftermarket parts with which the car could be
modified to meet practically any whim or application. When Henry
Ford applied the same basic concept to the farm -- offering a basic,
dependable machine at a low price - the results were similar. The
Fordson sold very well to farmers, most of whom had never before
owned a tractor. The tractor won so many customers, in fact, that
the little gray Fordson had a disastrous effect on a number of established
equipment makers. But while some factories closed, others opened:
a new industry grew up around the Fordson, as well.
Established
engineers and backyard welders alike came forward to offer features
and attachments that made the bare-bones Fordson tractor the picture
of versatility. They created and sold anything from rear fenders
(which the first Fordsons didn't have) to heavy contraptions of
angle iron, cables and gears that made the Fordson capable of digging
basements, grading roads or hauling dirt.
Henry Ford,
who became both celebrity and wealthy manufacturer, was the first
of eight children. With the success of Ford Motor Co., many of Henry's
immediate and distant family members opened Ford dealerships. Younger
brother William was hired in the employment office for the tractor
company and in 1920 William Ford & Co. became the tractor distributor
for Michigan and northern Ohio.
William Ford
entered the construction equipment business in 1925 with the formation
of the Wilford Shovel Co. in Detroit. The most obvious component
of the tracked 1/4-yard Wilford shovel was a gray Fordson skid unit.
In 1927 the company changed to Universal Power Shovel Co., with
William Ford as president. In addition to the Fordson powerplant,
the shovel used several parts from Ford cars and trucks: the crowd
device on the shovel was a Ford truck worm gear. The machine could
be purchased at Ford dealerships.
New
owners
United States production of the Fordson tractor ended in 1928, the
same year Universal found a new owner - Unit Corp. of America -
and a new powerplant - often McCormick-Deering. The shovel began
to look more like a purpose-built unit than a tractor conversion.
It was a given a 1/2-yard bucket and some models were fitted with
the large box-like cabs that were coming into vogue, while others
were mounted on truck chassis.
Wilford's new
owner was founded in 1918. Unit produced forged steel components
at its West Allis, WI, plant for railroad, agricultural, and other
industries. The excavator line was transferred from Michigan to
Unit's drop forge plant and production continued. In the 1930s the
shovel and forging businesses separated, and a group from Unit Drop
Forge left to run the new company. It incorporated in 1934 as the
Universal Power Shovel Corp.
Chief engineer
and company president Harold Brey gave the marketing department
an important exclusive when he developed a fully enclosed gear case
in which the components operated in an oil bath to significantly
reduce wear. The machines with Brey's unitized gear case were the
first to carry the Unit brand.
Ownership changed
again in 1940, and the name of the company became Universal Unit
Power Shovel Corp, simplified to Unit Crane & Shovel Corp. in
1956. During the World War II years, Universal produced cranes and
excavators for the military as well as anti-aircraft gun mounts.
Unit met the pent-up demand for equipment during peacetime with
an offering of crawler and wheel-mounted cranes, excavators and
material handling cranes. When the company celebrated its 25th birthday,
it was specializing in 5 to 30 ton cranes and 3/8 to 3/4 yard excavators.
Full
Vision cabs
The company developed a revolutionary cab during World War II. Introduced
as the Full Vision cab, the new Unit cranes abandoned the large
square housings used to protect machinery and man. The Full Vision
cab was a central feature on all subsequent models, including the
versatile Unit 357 mobile crane. Unit 357 was a wheeled machine
capable of 1,001 uses, the company advertised, including operating
as a shovel, dragline or crane.
Unit went off-shore
in the 1950s with the introduction of the popular Unit Mariner crane
for oil and gas platforms, and in the 1960s built a number of specialized
material handlers, including models used for placing Titan missiles
in underground silos.
The factory
moved to New Berlin, WI in 1967, and the last excavator was built
in 1982. Its production of the Mariner line and stationary cranes
used in scrap handling continued, however. In 1988 this business
was purchased by Offshore Crane Co. of New Orleans.
Unit Drop Forge
is still active in the off-highway OEM industry, although it doesn't
build complete machines. "Unit Drop Forge is alive and well,"
says Dennis Schloerke, sales manager. "We do closed-die steel
forgings between 10 lbs and 250 lbs. That size range is ideal for
the off-highway market."
Marketed as
Unit Forgings, mobile off-highway work accounts for 50% of its business,
which is still done in the original factory on 62nd Street in West
Allis, WI.
