TM 1-1740-204-13&P
a. Hand truck (1)
The hand truck (1) is fabricated of tubular steel. Its wrap around construction provides tip over protection for the
booster system and tanks. Retention means for two standard 230 cu ft nitrogen tanks is provided. Means for
attaching the booster panel and cleats for separately storing the tire filling and high pressure hose are provided.
The frame and axle locations provide for easy handling and tipping from the vertical to towing position. When the
cart is in the towing position, the coupler is 20 inches above the pavement and the ground clearance is 5 inches.
A MS 51336 lunette coupler for towing the cart is provided. 16 inch pneumatic tires permit a maximum towing
speed of 15 mph.
b. Booster Panel (2)
The components of the booster are mounted on the booster panel assembly (2) that forms an integral and easily
removable system. The panel is attached to the hand truck by six mounting bolts. The regulators are mounted
near the top of the panel to provide ease of operation and good visibility of the gauges. The booster pump system
is mounted on the lower portion of the booster panel assembly. Labels indicate the location of controls and
purpose of the gauges.
c. Booster Pump (3)
The booster pump (3) is a 30: 1 compression ratio, double acting, single stage, air driven pump with a rated
system gas outlet pressure of 4000 psi and a maximum air drive operating pressure of 150 psi. The pump is
capable of continuous operation at gas outlet temperatures of up to 300 degrees F.
An air pilot valve integral to the booster pump will shut off the pump when the nitrogen supply pressure is below
300 psi. Mufflers are mounted on the booster exhaust to provide noise attenuation during booster pump operation.
d. Regulators (4 and 5)
Low pressure regulator (4) sets the pressure of the tire filling output from the nitrogen tanks for tire inflation or
nitrogen gas to operate the booster pump. The high pressure regulator (5) sets the pressure available at the high
pressure output.
e. Tank Connector Assembly (6)
The tank connector assembly provides the means to connect one or two nitrogen tanks to the high pressure
nitrogen servicing cart. In line check valves prevent nitrogen from escaping when only one tank is used.
f. Accessories (7 and 8)
A 30 foot, 1/4 inch high pressure charging hose assembly (7) consisting of 27 feet of hose followed by a soft seat
needle shut off valve followed by a 3 foot length of hose terminated with a high pressure (5000 psi) inflating chuck
is supplied . The high pressure hose outer rubber jacket is perforated to prevent ballooning.
A 20 foot low pressure, 1/4 inch tire filling hose (8) is supplied with a 1/4 inch quick disconnect coupling socket that
mates with a quick disconnect coupling plug.
