The Role of Draglines in Earthmoving History
Draglines are among the most iconic machines in the history of excavation and mining. Unlike hydraulic excavators, draglines use a system of cables and winches to operate a bucket suspended from a long boom. This design allows them to reach far beyond their base, making them ideal for stripping overburden in surface mines, dredging, and large-scale earthmoving. Their simplicity and reach made them indispensable from the 1930s through the 1980s, especially in coal and phosphate operations.
Lima Locomotive Works and Its Transition to Heavy Equipment
Originally founded in 1879 in Lima, Ohio, Lima Locomotive Works was a major manufacturer of steam locomotives. As the demand for rail engines declined, the company pivoted toward construction equipment, eventually becoming Lima-Hamilton and later Lima Terex. By the mid-20th century, Lima was producing a range of cable-operated cranes and draglines, including the popular Lima 34 and Lima 44 series.
These machines were known for their rugged construction, mechanical reliability, and ease of maintenance. The Lima 34 was a mid-size unit often used in construction and dredging, while the Lima 44 was larger and more suited for mining and quarry work. Both models featured lattice booms, friction clutches, and diesel-powered winches.
Visual Identification and Key Features
Identifying a vintage dragline like a Lima 34 or 44 involves examining several visual and mechanical cues:
Operational Legacy and Collector Interest
Though cable-operated draglines have largely been replaced by hydraulic excavators and electric shovels, many Lima units remain in service or have been restored by enthusiasts. In Louisiana, for example, several vintage draglines are still used for pond excavation and levee maintenance, where their long reach and low ground pressure are advantageous.
Collectors and museums have also taken interest in preserving these machines. The Historical Construction Equipment Association (HCEA) has documented dozens of Lima draglines, and some have been restored to working condition for demonstration events.
Maintenance and Restoration Tips
For those restoring or operating vintage draglines:
Identifying a dragline like the Lima 34 or 44 is more than a technical exercise—it’s a journey into the heritage of American earthmoving. These machines represent a time when mechanical ingenuity and operator skill were paramount. Whether still digging or parked in a museum yard, they continue to inspire awe and respect among those who understand the power of steel, cable, and diesel.

Visual Identification and Key Features
Identifying a vintage dragline like a Lima 34 or 44 involves examining several visual and mechanical cues:
- Boom configuration: Lima machines typically used a lattice boom with diagonal bracing and a prominent heel pin assembly.
- Cab design: The operator’s cab was boxy, often with rounded corners and large windows. Older models had riveted panels, while later versions used welded steel.
- Counterweight housing: Lima draglines had a distinct rear counterweight box, often with access doors and ventilation grilles.
- Winch layout: The drum arrangement inside the machinery deck was symmetrical, with separate drums for hoist, drag, and swing functions.
- Branding and serial plates: These were usually mounted near the cab door or inside the engine compartment.

Maintenance and Restoration Tips
For those restoring or operating vintage draglines:
- Source parts from salvage yards specializing in cable cranes
- Use modern lubricants compatible with older gearboxes and bearings
- Inspect clutch linings and brake bands regularly, as these wear with use
- Replace electrical wiring with modern equivalents to prevent shorts and fires
- Document serial numbers and model tags for historical accuracy and parts matching
