A 50-Year Niche

Pettibone's Model 54 Cary-Lift has a lift capacity of 10,000 pounds. Cary-Lifts have been in production since the early 1950s.

 

Entrepreneur Phil LaTendresse ran a small manufacturing facility at L'Anse, Mich., called LaTendresse Manufacturing Co. He wanted a regular wheel loader to do more than merely load material. After several experimental machines, he invented the world's first forward-reaching, rough-terrain material handler in 1949, naming it the Cary-Lift. What sets the Cary-Lift apart from a regular wheel loader is its ability to extend its bucket arms forward and back when the machine is in a standing position. This is accomplished by attaching the pivoting loader arms to a movable frame that is actuated in turn by an extra pair of hydraulic rams.

When equipped with forks or pipe-handling grapple, this forward-reaching feature allows the operator to delicately pick and place a load or position the forks accurately under stacked material without having to depend on perfectly level ground. It also gives him superior forward reach capability beyond that of a similar-sized wheel loader. An additional bonus is full frontal visibility with overhead lifting arms pivoting at the rear.

In 1951, LaTendresse sold the Cary-Lift manufacturing rights to Pettibone Corp., and the first Pettibone Cary-Lift appeared soon afterward as the Model 54 with 10,000-pound lift capacity. In 1957, the company moved manufacture of the Cary-Lift from L'Anse to Baraga, Mich., where it is still manufactured by Pettibone Traverse Lift.

Over the years the Cary-Lift received many upgrades, and its design concept expanded into a wide range with lifting capacities from 4,000 to 70,000 pounds. The massive Super 70 Carry-Shovel of 1962 was powered by a Cummins 350-hp engine, carried a loader bucket of 26 cubic yards heaped capacity, and boasted a 6-foot forward hydraulic reach.

Pettibone Traverse Lift today operates as the Heavy Equipment Group of Pettibone LLC headquartered in Downers Grove, Ill. It is a direct descendent of the Pettibone company formed in 1881, which at that time was involved in manganese refining. Over the years, the company expanded into manufacturing and acquired a long list of companies. They operated at different locations but all under the umbrella of the main Pettibone corporation.

During the 1960s, the construction-equipment division (known as Pettibone Mulliken) operated eight integrated manufacturing plants. Products included wheel loaders, elevator loaders, bucket loaders, motor graders, mix-in-place concrete equipment, pumps, conveyors, rock crushers and screening and washing plants. Later, the company made a name for itself with rough-terrain mobile and hydraulic truck cranes.

Since its invention more than 50 years ago, the Cary-Lift has remained in continuous production and still forms the backbone of Pettibone's Heavy Equipment Division at Baraga, Mich.
