Alaco's Tapered Truss Ground Ladders or Ground Fire Ladders originate from an innovative design by Frederick Seagrave, who built wood orchard ladders in Columbus, Ohio before switching to fire ladders in 1881. His ultimate goal was to design and fabricate ladders that were:
- Very light for easy and fast handling
- Strong and tough to resist abuse
- Convenient to operate safely
- Stiff, with as little bounce as possible for quick, sure climbing
Seagrave's design was brilliant - even by today's standards. Over the decades it was developed further by Los Angeles Ladder Company, and has been continually refined by Alaco.
