STANDARD STAIR CROSSOVER SYSTEM

ALTERNATING TREAD STAIR CROSSOVER SYSTEMSABOUT LAPEYRE STAIR

Lapeyre Stair is a division of Laitram, a forward-thinking company with an intense commitment to innovation, integrity, and continuous

improvement. Laitram, headquartered in New Orleans, Louisiana, currently holds 1319 active patents.

Laitram founder, J.M. Lapeyre, with two of his early-model alternating tread stairs. J.M. established Lapeyre Stair following the issue of the patent for the alternating tread stair in 1981.

MORE SPACE? CHOOSE STANDARD STAIRS

Choose standard stair crossover systems if your application does not have any space restrictions. They require more space to install than alternating tread stairs but they are also the most comfortable to use.

LESS SPACE? CHOOSE ALTERNATING TREAD STAIRS

If space is limited in your application, choose alternating tread stairs. 68 degree alternating tread stairs require the least amount of space but the steeper angle is less comfortable to use. The less steep slope of 56 degree alternating tread stairs is requires less space than standard stairs and is more comfortable to use than 68 degree alternating tread stairs.

WHAT DOES OSHA SAY?

OSHA classifies alternating tread stairs (alternating tread devices) as non-standard stairs and states they are acceptable to use in applications where it is not feasible to use standard stairs. §1910.25(b)(8)

STANDARD CROSSOVER BRACING KIT

Alternating tread stair crossover systems must be braced to prevent swaying. List prices for these

systems includes our standard crossover bracing kit. The kit includes stainless steel brackets and

hardware for the upper and lower connections plus custom tubing in the same material and finish as your crossover system. Subtract $303.91 from the list price if you will provide your own bracing for the system.

We will need the following information when you place an order to calculate bracing specifications:

Dimensions of obstacles surrounding the system

Optimal spread angle (0° to 20° for 56° stairs; 0° to 10° for 68° stairs)

Optimal brace angle (20° to 30° from the vertical plane)

Contact us if you need help determining the spread and brace angles for your system.

OPTIONAL BACKPANS

Minimize the risk of damage to workers and equipment beneath your crossover system with optional backpans for

alternating tread stairs. Backpans bolt under the stairs to form a solid barrier behind the treads that spans the height of

the stair and provides protection from falling objects.

Pricing for optional backpans is based on the height of the stairs.

ADDITIONAL INFORMATION: The overall width and clearance width for all list price systems with standard stairs is 41½ inches. The overall width and clearance width for all list price systems with alternating tread stairs is 24 inches. The clearance span equals the platform span on standard stair systems less than 78 inches and on all alternating tread stair systems. Standard stair systems 78 inches and up require legs; the clearance span for these systems equals the platform span minus 11 inches.
