3.1
INSTALLATION
**************************************************************************
NOTE: As a minimum, the following are required on
drawings:
a. 2-1/2 to 3 meters (8 to 10 feet) wide loading
dock space behind ramp for vehicle maneuvering.
b.
Ramp located in the middle of one truck space.
c. Location of control station for power operated
ramps.
d. Location of disconnect switch with provisions
for padlocking in the open position which should be
just inside the nearest building door.
e. Ramp pits which should have steel angles
anchored to concrete on top three sides and dock
wall edge in bottom front of dock leveler pit.
**************************************************************************
Install and adjust in accordance with NFPA 70, manufacturer's approved
detail drawings, and as-built system assembly drawings. Install controls
so operator can see dock leveler while manipulating controls. Do not pour
the pit for the adjustable loading ramp until the design and detail
drawings have been approved. If the pit size is limited by construction
conditions involved, alter the dock leveler equipment to fit the pit.
Clearly indicate these alterations or modifications on the drawings. Check
and verify the appropriate measurements at the building. Do not exceed 50
mm 2 inch clearances between the ramp and pit.

CLEANING, TREATMENT AND PAINTING
In accordance with manufacturer's standard practice, shop clean, treat and
paint ferrous surfaces including platform, lip, frame, [springs,] [motor,]
[pump,] cylinders, [valves,] and any other non-cadmium plated or
non-galvanized surface (but not including bearings, gear contact surfaces,
parts protected by lubrication, or other surfaces not usually painted or
coated). Ferrous surfaces shall be cleaned, [shot penned, and the base
metal protected with an application of 99.9% pure zinc coating with a
thickness of o.010 to 0.012 IAW ANSI/ANS C2.18-93.] [and the base metal
protected with an application of Rustoleum paint with a thickness of 0.062
to 0.075 mm 2.5 to 3 mils followed by a final coat of standard primer with
a thickness of 0.062 to 0.075 mm 2.5 to 3 mils]. Protect nonferrous parts
against corrosion as necessary.
3.2.1
Workmanship
Conduct field touch-up work as to avoid damaging other surfaces and public
property in the area. Do not apply field applied paint during foggy, damp,
rainy weather, or the ambient temperatures below 7 degrees C 45 degrees F
and above 35 degrees C 95 degrees F.
