A Forgotten Giant of Cable Excavation
The Northwest 190 pullshovel represents a transitional era in excavation history—bridging the gap between cable-operated machines and the hydraulic age. Manufactured by the Northwest Engineering Company, which was founded in 1920 and became a dominant force in cable excavator production through the mid-20th century, the 190 series was designed for heavy-duty digging, trenching, and infrastructure work. These machines were widely used in waterline projects, road construction, and industrial site development across North America.
The 190 pullshovel was powered by a Detroit Diesel V-12, delivering robust torque to the winch-driven boom and bucket system. Unlike hydraulic excavators, the pullshovel relied on a series of cables, drums, and clutches to control the dipper arm and bucket, requiring skilled operators with precise timing and coordination.
Model Variants and Rare Configurations
The standard Northwest 190 evolved into several sub-models over time:
Preservation and Documentation Challenges
Due to the age and limited production of the 190 series, documentation is scarce. Brochures from the 1970s often omit the pullshovel variant, focusing instead on cranes and draglines. Some images and specifications survive in microfilm archives at university libraries, though resolution is poor and reproduction difficult.
To preserve knowledge of these machines:
Operating Characteristics and Maintenance Notes
Operating a Northwest 190 requires mastery of:
Conclusion
The Northwest 190 pullshovel stands as a testament to the ingenuity of mid-century excavation engineering. Though largely replaced by hydraulic excavators, its legacy endures among collectors, historians, and those who remember the rhythmic clatter of cables and the roar of a Detroit Diesel. With only a few surviving examples, the 190 remains a rare and revered artifact of the cable machine era.

Model Variants and Rare Configurations
The standard Northwest 190 evolved into several sub-models over time:
- 190-D: A mid-1960s to early-1970s variant, often seen in trade publications like Construction Methods & Equipment. It retained the classic cable configuration but introduced improved operator ergonomics and structural reinforcements.
- 190-DA: A rare capsule-cab version produced in the mid-1970s. This model featured a hydraulic cylinder-actuated bucket, blending cable and hydraulic technologies. Only a handful were built, making it one of the rarest Northwest machines ever produced.
Preservation and Documentation Challenges
Due to the age and limited production of the 190 series, documentation is scarce. Brochures from the 1970s often omit the pullshovel variant, focusing instead on cranes and draglines. Some images and specifications survive in microfilm archives at university libraries, though resolution is poor and reproduction difficult.
To preserve knowledge of these machines:
- Visit equipment museums that specialize in cable-operated machinery
- Contact historical societies in regions where Northwest machines were deployed
- Search trade journals from the 1960s–1980s for advertisements and field reports
- Network with retired operators who may have firsthand experience
Operating Characteristics and Maintenance Notes
Operating a Northwest 190 requires mastery of:
- Clutch timing: Engaging and disengaging drums without jerking the boom
- Cable tensioning: Preventing slack that could lead to misfeeds or snags
- Brake control: Managing descent speed of the bucket during digging
- Lubrication: Regular greasing of sheaves, drums, and pivot points

The Northwest 190 pullshovel stands as a testament to the ingenuity of mid-century excavation engineering. Though largely replaced by hydraulic excavators, its legacy endures among collectors, historians, and those who remember the rhythmic clatter of cables and the roar of a Detroit Diesel.
