Moldboard:
|
Moldboard shall be smooth rolled design. The
roll radius of the moldboard shall be 22" for the first 22" and
10" for the last 12". Moldboard shall be constructed of not less
than 10 ga. high strength carbon steel, A607 Grade 50 or equal.
Mild steel is not acceptable.
Moldboard shall be reinforced with two (2)
full length formed box sections of not less than 10 gauge, A-607-50
steel. The outer ends of the plow shall be reinforced with 5/8"
steel ribs extending from the lower support angle to the top of
the moldboard. Top edge of the moldboard shall be double flanged
or reinforced with a minimum 2" x 2" x 3/16" A-36 angle iron. The
bottom moldboard support structure or frog shall be a minimum 5"
x 3-1/2" x 1/2" thick A-36 MOD angle iron boxed the entire
distance between bolt holes for reinforcement.
Moldboard shall have built in snow deflectors.
The built-in snow deflectors shall extend approximately 6" beyond
a vertical line drawn from the leading edge of the cutting edge
when the attack angle of the cutting edge is at 15 degrees (measured
from vertical).

Hydraulic
Lift Cylinders:
|
Shall be two (2) minimum double
acting 3" diameter I.D.
X 11-1/2"" stroke. The cylinder
shafts shall be minimum 1-1/2" diameter and shall be coated
