During the operation, demonstrate the following:
a. Ability to load, transport, and unload.
b. Based on the primary highway fuel consumption both loaded and empty, calculate
travel distance per tank full.
c. Rocking of the mixer truck with load in soft, slippery, off-road terrain by cycle shifting
at not more than 2-second intervals from forward to reverse and back, continuously
for at least 60 seconds. Achieve at least 3/4 wide-open-throttle power in each gear.
Repeat the load.
4.3.2.9 Turning capability. Demonstrate vehicle clearance circle and curb clearance circle in
accordance with SAE J695, Field Test Procedures.
4.3.2.10 Braking-capability. Demonstrate the brake capability of the mixer truck. Conduct
service, emergency, and parking ability demonstrations.
4.3.2.11 High temperature operation. The contractor shall furnish test data to prove that the
truck-mounted mixer is capable of operating in an ambient temperature of 120oF without
exceeding the engine manufacture's recommended limits for radiator top tank temperature, engine
sump and gallery oil temperatures, and hydraulic component manufacturer's hydraulic fluid
temperature limits.
4.3.2.12 Test procedures of slinging provisions. Test procedures of slinging provisions shall
be as follows:
a. Lift the truck-mounted mixer and hold in suspension in its normal travel position using
slings that converge not more than 24 feet above the lowest extremity of the
truck-mounted mixer. Determine the true angle of the sling legs from the vertical.
Measure the clearance between each sling and the truck-mounted mixer. Measure eye
openings and clearance dimensions of the provisions. Measure the static load carried
by each provision.
b. Restrain the truck-mounted mixer by anchoring the main frame and subject each
provision to a working load force equal to the load factor specified in MIL-STD-209
times the load it carried in "a" above. An alternate method of test is to lift the
truck-mounted mixer as in "a" above and add weights to the main frame until the
required force is obtained. Hold the truck-mounted mixer under either of the above
loading conditions for at least 90 seconds.
4.3.2.12.1 Failure criteria. Weld failure or permanent deformation caused by lifting or failure
to meet the requirements of MIL-STD-209 shall constitute failure of this test.
4.3.2.13 Test procedures of equipment tiedown provisions. With the truck-mounted mixer
anchored by means other than the provisions being tested, apply the distributed loads as specified
in MIL-STD-209 to each attachment. Measure dimensions of the tiedown.
4.3.2.13.1 Failure criteria. Failure to meet the requirement of MIL-STD-209 shall constitute
failure of this test.
