arms 210a intercepting stop plates 218 the platform will be spring loaded this will also help 34 shock mount 34 in a suspended manner the platform 40 in the frame likewise when the platform reaches its lower limit the limit switch arms will intercept the stop plate before there is hard contact and the coil springs will take up the movement to spring load the platform when it is in its lowered position fig3 a also illustrates the use of a wire loom 220 such as that available from mcmaster carr to run wires used to energize the motor and the wires to the pelco u2122 unit and the remaining unit through to effect a clean structure further it is seen that wire loom 220 with wires therein is draped over a wire loom support plate 222 such that when the platform moves up and down the wire loom can lift cleanly off the top of the wire loom support plate and when the platform moves to a lower position can drape cleanly in the space beneath the platform motor 60 is held in place through use of motor mount bracket 224 which is bolted to base plate 20 motor relay mount bracket 226 is used to mount two 30 amp relays 228 for the motor 60 fig3 illustrates a gun mount assembly 100 for mounting a gun to the pan tilt unit the gun mount assembly includes a gun mount assembly mounting bracket 102 made.
