Rolling Ladders
Heavy-duty with the world’s tightest turning radius
and largest platform in the industry.
Built to work where other rolling ladders can’t
ProStep ultra-compact aluminum rolling ladders have a compact footprint and tight turning radius, opening up the spaces conventional rolling ladders can’t reach – built for warehouses, distribution centers, manufacturing, and MRO. They pair the industry’s largest published platform with an integrated handle that lifts the pivoting casters and locks the rubber-footed base – rolling to rock-solid in one motion.
- Compact. Maneuverable. Unstoppable.
With a tight turning radius and compact footprint, access equipment, corners, and aisles that other rolling ladders can’t reach. - More Room to Work
Large platforms and cantilever options provide more room and reach over equipment and obstructions. - Rock-Solid Stability
Engage the handle — casters lift, rubber-footed base locks, platform will not move.
- OSHA + ANSI Compliant
Built to OSHA 29 CFR 1910.23(e) and ANSI A14.7 — the standards your facility is already audited against. - Cost-Effective at Scale
In stock, fleet-priced – deploy across every aisle, bay, line, and MRO need - Proudly Made in the USA
Engineered, manufactured, and supported domestically — shorter lead times, accountable quality.
Why Prostep
Built to work where other rolling ladders can’t
In a world dominated by welded, fixed-form units, Prostep takes steps in a new direction.

Compact footprint & tight turning radius
With a tight turning radius and compact footprint, access equipment, corners, and aisles that other rolling ladders can’t reach. Warehouse floor plans are aisle-constrained; conventional rolling ladders are built for wide-aisle forklift lanes and cannot physically maneuver in tighter classes.
Stability & safety interlock
Lift-and-Lock
The integrated handle lifts the pivoting casters and locks the rubber-footed base — rolling the ladder from rock-solid to rock-solid in one motion. The unit is secured to the floor by the base, not by locking casters. While the casters are lowered, making the unit mobile, the handle safely prevents the unit from being climbed.
CAPABILITY EXTENSION
INDUSTRY’S LARGEST WORK PLATFORM
Choose 6 or 9 sq. ft. of standard workspace, then add a 1′ or 2′ cantilever kit to expand the platform up to 15 sq. ft. and reach over equipment and obstructions.
The range
Two widths, fifteen configurations
Available in 2′ and 3′ widths from 40″ to 120″, with up to 9 sq ft of working platform. Optional 1′ and 2′ cantilever add-ons extend reach over conveyors, equipment, and obstructions where a standard platform won’t go. OSHA 29 CFR 1910.23(e) and ANSI A14.7 compliant.
2′ Wide Platform
6 SKUs · 40″–90″ · 6 sq ft platform

3′ Wide Platform
9 SKUs · 40″–120″ · 9 sq ft platform

Cantilever add-on – Reach over what’s in the way

An optional 1′ or 2′ cantilever extension spans obstructions and reaches over equipment, conveyor lines, or curved surfaces without compromising guardrail protection. Bolt-on and field-installable — reach over an obstruction from an aisle-friendly base position rather than repositioning a larger unit that can’t fit the aisle in the first place.
Safety Gate Add-On
Add a YellowGate safety swing gate for work platform fall protection.
* Compatible with the 2′ wide platforms
