The most popular lines of commercial ladders include rolling ladders, industrial warehouse ladders, platform ladders, fixed ladders, and aluminum ladders. Rolling ladders combine mobility and safety. Platform ladders provide fixed, stationary positioning for working at high levels. Fixed ladders allow workers to safely climb vertically. Aluminum ladders are stable, lightweight, and built for convenience in both offices and warehouses.
Rolling ladders are extremely popular in the warehousing industry. The single-piece, rigid assembly of their design provides workers with a stable platform upon which to stand at a variety of elevations. The key to this stability is a number of safety features engineered into the caster assemblies. When the ladder is not in use, the casters roll. When the ladder is in use, the casters lock down, holding the ladder firmly in place. These commercial ladders meet or exceed OSHA and ANSI standards due to a number of engineering features:
- 7” deep steps
- 59 degree vertical rise
- Stable handrails
- 1” tubing assemblies
- Spring loaded casters that lock down when weight is applied
- Expanded 10” top metal step when ladder is in use
Rolling ladders are so popular in the warehousing industry that many manufacturers now make warehouse ladders specifically designed for bulk storage environments. Rigorous testing has gone into the manufacture of these lines to ensure compliance with ANSI A14.7 and OSHA 1910.29, and Cal-OSHA standards. Perhaps the most popular design features a ladder that can be tilted while rolling, increasing both ergonomics and maneuverability in the process. Additional stability is provided by handrails that rise 30 inches above the top step.
Many commercial ladders also feature work platforms at the top that allow workers to stand securely at various elevations. These single piece assembly ladders feature and average 50 degree vertical rise that facilitates easy climbing. The guardrails that surround the platform area form an enclosure that measures, on most models, at least 42 inches in height. Some platform ladders are actually two ladders combined into one. These models feature steps on either side leading up to the elevated platform in the center.
ANSI and OSHA 1910.29 compliance result from a number of engineering features that include:
- Front legs held in place during use by large, 1 inch thick rubber pads
- 4” rigid casters Safe-Lock assembly for greater maneuverability and lock-in-place security
- Non-slip platforms supported by 1 inch tubular steel frame
Fixed commercial ladders are needed in applications where workers must climb a vertical surface at a near 90 degree angle to the floor. It has become industry standard to build safety cages on the tops of these ladders to prevent workers from falling. Various models feature a single-piece assembly or a modular design consisting of segments no longer than 7 inches each. Sizes range from 10 feet to 29 feet in height.
Aluminum ladders are easy to carry and provide a good, stable alternative to steel ladders in applications where a smaller ladder will suffice. Key features include:
- High-strength aluminum tubing
- Swivel brake casters
- Ribbed aluminum steps for traction
Built for up to 350 pounds of load, these smaller commercial ladders are ideal for small stockrooms, office storage rooms, and auto repair shops.
