Partially disassemble the patient couch for narrow carrying-in routes (CBTB-018A only)
Partially disassemble the patient couch to reduce its carrying-in size by 300 mm, for installations where the carrying-in route is not wide enough for the couch at full length. This is a reversible disassembly — mark parts before you start so the couch can be correctly re-assembled once it is through the route (see Preparation, below).
Tools & parts
| Item | Part number | Qty |
|---|---|---|
| M12 bolt(s) — couch top to moving frame | n/a in source | not stated in this appendix (figure label "M12 bolt" has no count) |
| M8 bolts — belt fixing plate | n/a in source | 4 |
| M8 bolts — couch-top slide frame | n/a in source | 6 |
| M8 bolts — LM (linear) guide | n/a in source | 17 |
| M8 bolts — rear-end frame | n/a in source | 7 |
| Marking materials (e.g., paint marker / tags) | n/a in source | n/a in source |
Safety
Hazard: Bending the belt while removing the belt fixing plate (Step 2)
Consequence: The appendix does not spell out the failure mode beyond the caution itself; a bent fiber-reinforced belt is documented elsewhere in this manual (sibling drive-unit sections) as no longer functioning correctly once bent
Avoidance: Be careful not to allow the belt to be bent when removing the belt fixing plate (source CAUTION, Step 2).
Hazard: Removing the rear-end frame without first disconnecting the connectors and grounding wires from the parts mounted on it, or mishandling the cable wires during removal (Step 5)
Consequence: Cable wires can be broken
Avoidance: Disconnect the connectors and grounding wires from the parts on the rear-end frame in advance, and take care not to break the cable wires when removing the frame (source NOTE, Step 5).
Hazard: Removing the upper covers named in Step 1 (front cover, side covers, rear cover, rail covers, couch top bottom cover) with the equipment powered on
Consequence: Exposes the technician to the couch drive unit underneath while it is live
Avoidance: Turn OFF the power before removing these covers — this appendix does not repeat the CAUTION, but the dedicated Upper Covers section (§2.2.7), which covers this exact same set of covers, states it directly: "Be sure to turn OFF the power before mounting and removing the covers."
Hazard: Handling the couch-top slide frame (6× M8), LM guide (17× M8), and rear-end frame (7× M8) as their retaining bolts are progressively removed, with no support/two-person call-out printed in this appendix
Consequence: A frame section can shift, tip, or fall once its last retaining bolts are removed, causing a pinch, crush, or dropped-load injury
Avoidance: Support or brace each frame section before removing its final bolts, keep hands clear of pinch points as sections separate from the couch, and do not let any section fall uncontrolled. Not printed as its own callout in this appendix; grounded in the same handling caution the manual gives for other heavy couch components (e.g., the hydraulic unit, G-CA16/G-CA17).
