Origins of Pettibone Equipment
Pettibone was an American manufacturer that gained recognition in the mid-20th century for producing rugged construction and material-handling machines. Founded in the early 1900s, the company initially focused on railroad maintenance equipment before expanding into cranes, loaders, and eventually excavators. By the 1960s, Pettibone had established a reputation for innovation, particularly in rough-terrain cranes and backhoe loaders. Their entry into the excavator market was less well known, but it reflected the company’s ambition to compete with established brands such as Caterpillar, Bucyrus-Erie, and Link-Belt.
Development of the Pettibone Excavator
Between 1969 and 1971, Pettibone introduced hydraulic excavators such as the BH70 model. Hydraulic technology was becoming the industry standard, replacing older cable-operated machines. The BH70 was designed to offer improved digging efficiency, smoother control, and reduced operator fatigue. Technical specifications included a hydraulic system capable of delivering consistent power, a boom reach suitable for mid-scale earthmoving, and compatibility with multiple attachments. While exact production numbers are scarce, industry estimates suggest only a limited run was manufactured, making these excavators rare today.
Design Characteristics
Comparison with Pettibone Cranes
Pettibone was better known for its cranes, including rough-terrain and truck-mounted models. In Duluth, Minnesota, the company produced cranes ranging from 60 to 100 tons, many of which were sold to railroads. The crane division enjoyed stronger sales than the excavator line, which remained niche. This imbalance explains why Pettibone excavators are rarely seen today, while Pettibone cranes are still remembered in industrial circles.
Market Reception and Sales
Unlike competitors who sold thousands of excavators annually, Pettibone’s excavator sales were modest. Industry reports suggest fewer than a few hundred units were produced. The limited distribution meant that many contractors never encountered a Pettibone excavator, even though they were familiar with the company’s cranes and loaders. This scarcity has made surviving machines collectible among enthusiasts of vintage heavy equipment.
Terminology Explained
Workers from Duluth recall seeing Pettibone cranes fitted with rail trucks, serving railroad companies across the Midwest. Some retired operators mention that Pettibone excavators were sleek but rare, often overshadowed by larger brands. Collectors today occasionally find Pettibone machines at auctions, where they attract attention due to their unusual design and limited production.
Modern Perspective
The Pettibone excavator represents a fascinating chapter in construction equipment history. While it never achieved mass-market success, it demonstrated the company’s willingness to innovate beyond its core crane business. For modern contractors, the lesson is clear: diversification can be risky without strong distribution networks and brand recognition. For collectors and historians, Pettibone excavators are valuable artifacts that highlight the transition from cable to hydraulic technology.
Conclusion
The Pettibone excavator remains a rare but important example of mid-20th-century engineering. Its limited production, distinctive design, and connection to a company better known for cranes make it a subject of curiosity and admiration. Though overshadowed by industry giants, Pettibone’s attempt to enter the excavator market reflects the dynamic and competitive spirit of the construction equipment industry during the hydraulic revolution.

Terminology Explained
- Hydraulic Excavator: A machine that uses hydraulic cylinders and pumps to move its boom, arm, and bucket.
- Rough-Terrain Crane: A crane designed with large tires and suspension for off-road construction sites.
- Backhoe Loader: A versatile machine combining a front loader bucket with a rear digging arm.
