Chapter 5 FLOOR LOADING AND WEIGHTS Section 1.0 Floor Loading Section 2.0 Seismic Data The CT system has a total floor load of approximately 6660 lbs (3021 kg). About 5050 lbs (2291 kg), including patient (450 lbs (204 kg)), is concentrated in the table-gantry assembly. Table 5-1 shows CT components with size and weight, floor loading and normal mounting requirements. The following pages show center-of-gravity information for system components: Gantry: Figure 5-1 Table: Figure 5-3 Power Distribution Unit: Figure 5-4 Operator's Console/Computer: Figure 5-6 Floor and wall mounting hole locations for components which don't have templates are also in this section.
