This comprehensive overview explores the evolution and impact of Manitowoc cranes—from early lattice‑boom models to modern global lifting solutions. Alongside technical definitions, real-world anecdotes, and industry developments, it offers a detailed narrative of one of the most influential names in crane manufacturing.
Origins and Historical Development
Manitowoc began in 1902 in Wisconsin as a shipbuilding business (the former Burger & Burger shipyard) that evolved into Manitowoc Shipbuilding Company. Facing post‑war decline in marine contracts, the founders diversified into crane manufacturing in the mid-1920s .
In the early years, Manitowoc produced crawling and lattice‑boom cranes based on designs adapted from Moore Speedcrane models. By acquiring patents and refining crawler bases, they transitioned to producing original heavy cranes—setting a new standard in lifting design .
By the late 1960s–70s, crane sales outpaced shipbuilding. Manitowoc introduced innovations like high‑strength T‑1 steel booms and the controlled‑torque converter, and its annual crane revenue surpassed that of shipbuilding by a wide margin .
Evolution Through Acquisitions & Brands
Over the years Manitowoc expanded through strategic acquisitions:
• 1994: acquired Femco Machine Company, forming an aftermarket parts group.
• 1998: launched West‑Manitowoc to reintroduce small lattice‑boom crawler cranes, then folded into the main brand.
• 2001: acquired Potain SAS (tower cranes); 2002: Grove Worldwide (telescopic mobile cranes).
• Manitowoc also absorbed National Crane (boom trucks), and its lift equipment network expanded globally under multiple sub‑brands .
In 2016, Manitowoc spun off its foodservice division and became solely a craning company, focusing entirely on engineered lifting products .
Product Lines & Capabilities
Manitowoc now offers a broad range of lifting solutions:
• Lattice‑boom crawler cranes under the Manitowoc name—trusted for mega‑lift applications.
• Tower cranes via Potain—often deployed in tight urban construction.
• Mobile cranes (rough-terrain, all-terrain, truck-mounted) using Grove and National Crane brands.
• Comprehensive aftermarket support including parts, training, fleet management (CraneSTAR), diagnostics and financing .
Terminology & Innovation Highlights
• Lattice‑boom vs telescopic cranes: lattice‑boom cranes offer high capacity and strength, while telescopic cranes like Grove’s deliver mobility and ease of transport.
• Self-assembling cranes: starting with the M‑250 in the early 1990s, Manitowoc developed cranes that could self‑rig in hours, enabling models like 888, 777, 999, and the massive 31000 crawler crane .
• Boom Truck vs Shuttlelift: National Crane boom‑trucks integrate with Grove under Manitowoc branding for mobile lifts.
Case Stories & Anecdotes
An enthusiast once posted photos of a “Manitowoc Sea Crane”—a rare barge‑mounted crane used offshore. Only six such cranes were built, and one was documented lifting an entire 3900-series crawler. A forum contributor noted that models “601” and “602” ended up in Nigeria, while “604” remains mounted on the Arapaho/Tetra barge, with one unit’s fate still a mystery .
Famed engineer John Lanning, instrumental in developing Manitowoc’s self‑assembling cranes, later joined SANY America to develop new models there—bringing over decades of lattice‑boom design expertise to global users .
Summary: Why “Real Manitowoc Power” Still Matters
• Heritage: Over a century of engineering—from shipyards to world-leading crane design.
• Innovation: Industry-firsts like controlled‑torque converters, self‑rig assembly and boom strength technologies.
• Global portfolio: Tower, crawler, mobile, boom-truck cranes with strong aftermarket support.
• Reputation: Used for major infrastructure, offshore lifting, stadium projects, and modern high-rise builds.
Terminology Glossary
• Lattice‑Boom Crane: A crane using lattice-structured, bolted booms—ideal for high load and height applications.
• Telescopic Crane: Variable-length boom cranes (truck‑mounted or rough-terrain) offering rapid setup and maneuverability.
• Self‑Assembling Crane: Crane able to rig itself with limited crew and minimal setup.
• CraneSTAR: Manitowoc’s integrated fleet management and diagnostic software platform.
Conclusion
From Manitowoc’s humble shipyard beginnings to its current position as a global crane powerhouse, the brand’s legacy is built on reliability, innovation, and adaptability. Whether lifting a building fragment with a tower crane or deploying a sea‑mounted crawler off a barge, Manitowoc cranes—and the engineers behind them—have shaped the modern lifting industry.
