Section X. TRUSS SUPPORT ASSEMBLY
The truss support assemblies are the legs of the camera. The
trues supports (8, fig. 1-1) on the copyboard end of the camera
skid (11) support the transformer (2, fig. 4-13) and magnetic
contactor (5) by a rear support plate (4), which serves as a
mounting base connecting the two truss supports. The truss
supports are rigidly bolted to the camera skid and are
crossmembered at the top by a support channel. The truss
support (8, fig. 1-1) on the darkroom end is similarly mounted,
with the exception that it is not equipped with a support plate
and the circuit breaker boxes (6, fig. 6-17) are mounted on each
side of the truss support.
