3.4 Ceiling Requirements
Aluminum rails support the In–Room Monitor bridge used in Optima system X–ray rooms.
Reference:
For additional details on ceiling requirements for stationary rails, refer to: - Direction 46–019639,
Advantx (VHLA) XT Stationary Rails Installation and Adjustment.
When evaluating ceiling you must take into account the following mounting information:
3.4.1 Rail Mounting
Attach stationary rails to structural steel with through-bolts in concrete ceilings. Do not use
screw anchors in direct tension.
Mount stationary rails directly to the ceiling slab or to flush–mounted unistrut or halfen structure.
In higher rooms with false ceiling, mount stationary rails to rigid vertical members hung from
ceiling slab.
Securing a supplementary channel to the bottom of the vertical members and mounting the
stationary rails to this channel can greatly reduce the number of vertical members.
The stationary rail support structure must be leveled before installation can begin. Do not
assume that any support structure is level within specified tolerances, particularly after removing
suspensions from an existing room.
(For Ergo suspension) Holes for diameter 12 mm (1/2") bolt are mandatory. For normal use,
each part of the ceiling rails must be fixed at the correct level. The tolerance of the fit level is ±
1.5 mm (0.06").
3.4.2 Bolt Specifications
3.4.2.1 Mavig suspensions
•
The maximum load per bolt will not exceed 1557 N.
•
Each bolt must not “pull out” or otherwise fail under a vertically downward
dead load of 6227
N.
3.4.2.2 Ergo suspension
The stationary rail hole accepts normal bolts used by HALFEN or UNISTRUT with 12 mm (1/2")
diameter. GE Healthcare provides M12 mm (1/2")- 40 mm (1-1/2") long metric bolts together
with the rail assembly. For other special bolts required, local Field Service supplies them
according to country standard or the additional structure mounted on site.
The maximum load per bolt will not exceed 1895 N (426 lbs).
Each bolt must not “pull out” or otherwise fail under a vertically downward “dead” load of 7580 N
(1704 lbs).
