MIL-H-62185(AT)
3.6.14.1.1 Cab ring friction. With the vehicle horizontal within 2 degrees the turret assembly
mounted to the hull, and the turret complete with slip rings, but without traverse gear box output
pinions installed, the torque required to rotate the turret shall not exceed 700 foot pounds after
breakaway.
3.6.14.1.2 Cab traversing speeds. The cab shall be controllable in traverse at all speeds
between 0.5 mils per second and 3 rpm. The tracking speed shall range from not more then
0.5 mils per second to not less than 65.2 mils per second and the transition between these two
speeds shall be smooth and gradual. At speeds above 65.2 mils per second, cab speed shall
increase with increased control handle displacement until maximum velocity is reached. The cab
speed at this point shall be not less than 3 rpm. The speed shall remain stable at all times. These
requirements are applicable to gunner power controller only.
3.6.14.1.3 Manual traverse effort. With the vehicle horizontal within 2 degrees, the
following cab performance is required. The average force applied tangentially to the traverse
hand-crank at a uniform rate, to maintain cab movement, shall not exceed 16.5 pounds with
10 mils per turn rate. With 5 mils per turn rate, effort to maintain cab movement shall not exceed
9 pounds.
3.6.14.1.4 Manual traverse response rate. With traverse mechanism shifted to high range,
one revolution of the hand traverse crank shall rotate the cab 9 mils minimum. With traverse
mechanism shifted to low range, one revolution of the hand traverse crank shall rotate the cab
5 mils minimum.
3.6.14.1.5 Weapon slope operation. With the vehicle pitched up to 6 degrees and canted up
to 5 degrees, the control system shall be capable of rotating the turret 360 degrees right and left
with bath power and manual controls.
3.6.14.1.6 Hydraulic pressure limit switch. When power traversing the cab at a rate not to
exceed 65 mils per second, the hydraulic system pressure switch shall actuate the hydraulic
control power pack motor at a control system pressure of 880 to 970 pressure per square inch
(psi), to be indicated on the pressure gage. With the gunner's and number one man power and
manual controls in neutral position, the hydraulic pressure switch shall deactivate the hydraulic
power pack motor at a control system pressure as indicated on the gage between 1150 and
1500 psi.
3.6.14.2 Weapon control system.
3.6.14.2.1 Elevation system protection. There shall be no damage to the control system or
any component as a result or positioning the gun mount against the elevation and depression stops
by power or manual controls. Power and manual controls shall be regained instantaneously from
this action. The gun mount shall engage the weapon stops at elevation of between minus 36 mils
to minus 54 mils and between plus 1315 mils and plus 1333 mils.
