People Also Ask
What angle should I choose for a ships ladder?
Shallower angles (60°–65°) climb more like stairs and suit frequent use, while steeper angles (70°-80°) save floor space in tight areas. OSHA 1910.25(e) defines ship stairs as being 50° to 70° from the horizontal, so the angle selection can also affect how your installation is classified. Our team can advise on the right fit for your space and code requirements.
What is the difference between a ships ladder and a folding ladder?
A ships ladder (H-series) is a fixed, permanently installed steep stair. A folding ladder (HP-series) stows flat against the wall or ceiling when not in use, ideal for corridors, closets, and spaces that need clear floor area between uses.
What is a retractable roof hatch ladder?
A retractable ladder, like the Alaco 660, slides away when not in use, keeping the area beneath the hatch completely clear. It suits locations where a fixed or folding ladder would obstruct walkways or equipment.
What file formats are the drawings available in?
All roof hatch ladder drawings are available in PDF, DXF, and DWG formats, with specifications in DOC and PDF. DWG and DXF files work with AutoCAD and most CAD software for direct use in project drawings.
Can Alaco build these ladders to custom dimensions?
Yes. Every Alaco ladder can be built to custom heights, widths, and angles to fit your hatch location and floor-to-ceiling dimensions, with project-specific shop drawings provided for submittals.
