Dual Table Alignment Procedure

Prerequisites

Overview

These procedures are applicable to the following table products:

  • Signa Lightweight Patient Transport Table

  • Signa Oncology Patient Transport Table Option

  • Signa OR-Compatible Patient Transport Table Option

The alignment procedure requires:

  • One person for a Signa Lightweight Patient Transport Table

  • Two people for a Signa Oncology or Signa OR-Compatible Patient Transport Table Option

Procedure

  1. Remove the cradle from both tables, see Removing Cradle Assembly. Step 2Figure 1.

    Figure 1. REMOVE CRADLES FROM TABLES

  2. Remove the plastic covers from the castings. Figure 2.

    Figure 2. CASTER COVER AND HEIGHT

  3. Center the dock assembly with the bridge, at the front of the magnet "Loosely attach the Dock assembly to the front of the magnet. Do not secure the Dock to the magnet or floor. Centering will be accomplished in Step 6." Figure 3.

    • warning
    • Personal injury and equipment damage
    • Strong Magnetic Field
    • Safety Requirements
      • The service path must allow for the dock to be moved along the ground a distance equal to that of the distance between the magnet and the foot-end of the patient table prior to being lifted vertically.
      • Two (2) MR safety trained personnel must be present at all times when servicing highly ferrous devices in the areas of magnetic fields.
    • When planning a service path, it is critical that the path be clear and sufficiently wide. Ensure that there are no trip hazards, obstacles, clutter, slippery surfaces or other items even partially restricting the path. If there are portable obstacles in a path, remove them from the area and replace them after the service action is completed. It is required to walk the path prior to beginning service to ensure that there is sufficient space through which to pass for yourself and the object being serviced.

    • warning
    • POSSIBLE PERSONAL INJURY
    • TO OPPOSE ANY PULL FROM THE MAGNET, FIELD ENGINEERS MUST APPLY CONTINUOUS DOWNWARD PRESSURE TO THE TOP OF THE DOCK whenever the dock mounting hardware is loose
    • DO NOT PLACE ANY PART OF THE HUMAN BODY IN THE PATH BETWEEN THE DOCK AND THE MAGNET.
  4. Center the Dock assembly by using a Plumb Bob (Non magnetic material). Figure 4.

    Figure 4. CENTER THE TABLE

  5. Use the ¾” socket to adjust both front casters of table such that the top of the casting above the wheel is 11.00 (279.4mm) inches from the floor. Figure 2
  6. Position the table to the dock, taking care not to move the dock. DO NOT actuate the docking pedal. Figure 5.

    7. Notice Image
    • notice
    • Over adjusting the caster adjustment will lead to caster being damaged. Do not exceed the +/- 0.25” (6.35mm) tolerance.
  7. With table #1 fully elevated, align the table top to the bridge (which should be flush to 1 mm below the end bells) by adjusting the front two casters, see Figure 6. Raise and lower the casters as needed while keeping the center (between the two casters) close to the 11” (279.4mm) height. REMEMBER, the casters should never be adjusted more than +/- .25” (6.35mm) from the 11” (279.4mm) height. Figure 7. (Adjusting the high side down and the low side up by the same amount ensures the dock center will stay aligned with the Patient Transport docking mechanism.)

  8. Move the table and dock left or right until the table rail and the bridge rail are in alignment. See Figure 8.

    9. Notice Image
    • warning
    • POSSIBLE PERSONAL INJURY
    • THE DOCK CONTAINS HIGHLY FERROUS MATERIAL. THIS PROCEDURE REQUIRES MOVEMENT OF FERROUS MATERIAL IN CLOSE PROXIMITY TO THE MAGNET.
    • Therefore, two Field engineers are required at all times.

    • POSSIBLE PERSONAL INJURY
    • TO OPPOSE ANY PULL FROM THE MAGNET, FIELD ENGINEERS MUST APPLY CONTINUOUS DOWNWARD PRESSURE TO THE TOP OF THE DOCK whenever the dock mounting hardware is loose.
    • DO NOT PLACE ANY PART OF THE HUMAN BODY IN THE PATH BETWEEN THE DOCK AND THE MAGNET.
  9. Place a mark on the floor adjacent to the side of the dock. (tape)
  10. Repeat stepsStep 6 toStep 9 for table #2 and then continue with Step 10.a.
    1. Mark the center point between the 2 marks. Figure 9.
    2. Shift the dock assembly to align with the center point mark.

      Figure 9. EXAMPLE OF RESULTS FROM THROUGH

  11. Secure the dock assembly in position.
  12. Complete the final lateral alignment by adjusting the front two casters if necessary. Raise and lower the casters as needed while keeping the center (between the two casters) close to the 11” (279.4mm) height. REMEMBER, the casters should not be adjusted more than +/- .25” (6.35mm). Figure 7.
  13. Tighten the Bushing Screw at on each caster.
