Specifications

Proposal Number PSDF #P09-0004
furnished to deploy the hose without opening the cover. The hosereel shall be mounted between the bumper
extension rails.
A diamond plate hinged cover shall be furnished. A "D-Ring" handle shall be used to open the lid with a gas
shock to hold the lid in the open position.
CHASSIS GREASE SYSTEM
The chassis shall be equipped with a VOGEL Centralized Lubrication System. This system shall provide
automatic grease application to the following wear points:
Kingpins (4), Tie Rods (2), S-Cams (2), Slack Adjusters (2), Spring Pins (6), Draglink (2),
S-Cams (4), Slack Adjusters (4), Spring Pins (4)
This grease system shall utilize NLGI000. The system shall be powered by an electrically driven gear pump,
12 volts, 192 watts. The gear pump shall be mounted to a reservoir with a capacity of 2.7 liters. The pump is
to operate against a back pressure of 38 bar nominal, with an output of 160 cc/min.
Distribution to all lubrication points is by piston distributors. The distributors shall utilize metering nipples.
Metering for the nipples shall be in the increments of 0.1, 0.2, 0.3, 0.4, 0.6, and 1.0 cc. The metering nipples
shall be able to be field changed to provide a tailored grease application to the chassis points. The distributor
shall dispense a metered volume of lubricant into the lube point after the electric motor gear pump has cycles
to the off-time mode.
The cycle time of the system shall be determined by an electronic controller, which regulates the on and off
time of the pump. The controller shall permit the feedback of the pressure switch to highlight the end of the
lube cycle.
A hand pump and container of grease shall be shipped loose with the chassis for initial maintenance by the
department.
FRONT AXLE
The front axle shall be a MERITOR axle with the minimum rated capacity of 21,500 lbs. The actual
capacity shall be determined by the manufacturer. This to include the fully loaded vehicle, 1500 pounds of
personnel and equipment in the cab, and 8,000 pounds of hose and equipment in the body and full tank of
water and full tank of fuel.
CRAMP ANGLE
Due to the traffic, narrow streets and sharp corners the chassis turning radius is important, both left and right
turns.
The bidder shall supply, with the bid, an engineering drawing that provides a top view of the apparatus with
the following turning ability information listed in decimal feet: SAE turning radius, curb to curb radius,
bumper swing radius, inside radius. The calculations must be performed according to SAE J-695.
