Chalfant Aluminum Ladder Tray –Extra Long Span
Shall have a UL Classification Label and conform to NEMA VE-1 Standards and be manufactured entirely
(side rails, rungs & splice plates) of 6063T6 aluminum alloy (copper free) for maximum corrosion resistance.
Shall have a side rail height of (A)* with an inside load depth of (B)* and a NEMA load/span capability of (C)*
at (D)*. The simple beam deflection of the tray system, at the above conditions, shall not exceed (E)*. Side
rails shall be “I” Beam** design with reinforced top flanges. The widths shall be 6,9,12,18, 24,30 & 36”.
Shall be installed on (9, 12 OR 18”) centers and shall be strut construction with minimum 1 5/8” width, 1/8”
radius on edges. Rungs shall be MIG welded to the web of the side rails. Spot welding or swaging will not be
accepted. Rungs shall have capable of supporting an additional 200 lb concentrated load anywhere on an
individual rung or along the span of the tray.
Shall have 36 or 48” smooth radius. They shall have a 8” minimum tangent for simple transitions and splice
plate connections. (Because of the heavy duty fitting side rails we can not form 12 or 24” radii) Small radius
fittings would have to be mitered.
Splice Plates & Hardware:
Splice plates shall be fabricated with a 10 hole pattern. Holes shall be slotted for easy field assembly.
Hardware shall be 3/8” 302 stainless steel round head serrated bolts with 304 stainless steel hex nuts with
integral lock washer.
Shall be aluminum or stainless steel. Tray shall be isolated from bare steel with PVC spacers or glide strips.
