Specifications

Proposal Number PSDF #P09-0004
OUTRIGGERS AND STABILIZERS
The aerial stabilizer assemblies, outriggers assemblies, beam, outer jack tube, inner jack tube, jack cover
plate, and jack pad shall be galvanized.
The outriggers and stabilizers shall be galvanized inside and out. The process shall eliminate the rusting,
scratching or paint chips on the outriggers. The galvanizing process shall permeate the metal and shall not
be an "over-coating only" on outside surfaces. The galvanized components shall lessen the potential for
corrosion and eliminates the requirement for finish paint. The process shall negate any later requirement for
touch-up paint or total repaint of the outrigger/stabilizer assemblies.
The galvanizing shall provide the steel outriggers with both barrier and cathodic protection from corrosion.
The galvanizing process shall immerse the complete outrigger and stabilizer components in molten zinc. The
galvanizing diffusion process shall allow the zinc to bond to the steel, at the molecular level. The galvanized
zinc coating shall provide a barrier that shields the steel from the environment.
HANDRAIL COLOR: BLACK
The turntable handrails shall be coved with a black slip-resistant coating.
AERIAL LADDER BED
On the base section of the aerial device, a stainless steel scuff plate shall be installed where the aerial comes
in contact with the travel support.
AERIAL LADDER RUNG SPECIFICATIONS
For ease of climbing the ladder rungs shall be equally spaced on a maximum 14" centers and minimum
11.75" centers and shall have a skid-resistant surface or covering.
For added safety, skid-resistant rung covering shall be provided. The rung covering shall not twist and shall
cover at least 60 percent of the climbing area of each rung.
Round rungs shall be provided and shall have a minimum outside diameter of 1-1/4", including the skid-
resistant surface or covering.
For maximum strength, the minimum design load for each rung shall be 500 lb distributed over a 3-1/2" wide
area at the center of the length of the rung with the rung oriented in its weakest position.
NON-SKID AERIAL RUNG COVERING
Each aerial rung shall be covered with two (2) pieces of a protective, 3-M safety walk non- skid material.
AERIAL WEAR PADS
The aerial wear pads shall be easily adjustable and designed to make replacement easy.
