Introduction
In the mid-20th century, the construction and railroad industries faced challenges in handling heavy materials in rugged terrains. Traditional cranes were often too bulky or lacked the necessary mobility. Pettibone, a company with a rich history in material handling equipment, recognized this gap and introduced the Multikrane series—a line of mobile hydraulic cranes that combined versatility with power.
The Birth of the Multikrane Series
Pettibone, established in 1881 as Pettibone Mulliken, initially focused on manufacturing railroad track equipment. Over time, the company expanded its product line to include cranes and other material handling equipment. In the 1950s, Pettibone introduced the Multikrane series, which featured a unique design that allowed the crane's cab to rotate independently of the chassis. This "swing cab" design provided operators with enhanced visibility and maneuverability, making it ideal for confined spaces and challenging job sites.
Design and Features
The Multikrane series was characterized by its robust construction and innovative features:
- Swing Cab: Allowed the operator to rotate the cab 360 degrees, providing better visibility and control.
- Hydraulic Boom: Enabled precise lifting and placement of heavy loads.
- Rough Terrain Capability: Equipped with large, durable tires and a high ground clearance to navigate uneven surfaces.
- Versatility: Compatible with various attachments, including hooks, buckets, and grapples, to handle different materials.
Several models of the Multikrane series gained prominence in the industry:
- Model 30: A 15-ton capacity crane with a three-section telescopic boom, suitable for light to medium-duty tasks.
- Model 70: A 35-ton capacity crane with a longer reach, designed for heavier lifting operations.
- Model 100: One of the larger models, offering increased lifting capacity for more demanding applications.
The Multikrane series revolutionized material handling in industries such as construction, railroad maintenance, and utilities. Its combination of mobility, power, and versatility allowed operators to perform tasks more efficiently and safely. Many of these cranes remain in service today, a testament to their durability and the foresight of Pettibone's design.
Conclusion
Pettibone's Multikrane series stands as a significant achievement in the evolution of mobile cranes. By addressing the industry's need for versatile and powerful equipment, Pettibone not only enhanced operational efficiency but also set new standards in crane design. The legacy of the Multikrane continues to influence modern crane technology, underscoring Pettibone's role as a pioneer in the field.
