About this task

For proper Patient transport Cradle movement, the Table top height should be in line with the Gantry Bridge.

Procedure

Measure the height difference between the Guide ridge (cradle rolling area) of Tabletop and guide ridge (cradle rolling area) of the bridge. If adjustment is required, Remove the left top side cover from the Table. Refer to SCISSOR COVERS.

Figure 1. Measure the height difference
Actuate the down pedal, Move the table down by approximately 100mm.
Loosen the Lock nut of UP Limit switch (LS) actuator. Refer to Figure 2 for the location of Up Limit Switch Actuator.

Figure 2. Location of Up Limit Switch Actuator
One Clockwise rotation of the Up Limit switch actuator will lower down the Table by 1mm. One Anti-clockwise rotation of the Up Limit switch actuator will raise the Table by 1mm. Adjust the Up Limit switch actuator with respect to the measured height difference. Lock the Nut using the spanner (3/8-7/16). See Figure 3 for the adjustment. Align the position of the LS Actuator such a way that it engages the Limit switch when table is taken to topmost condition. Refer to Figure 4. Tighten the Lock nut

Figure 3. Up Limit Switch Actuator Adjustment

Figure 4. Allign the position of the LS Actuator
Raise patient transport to maximum height using UP pedal.
Check alignment of Table Top against the bridge. Guide ridge down length of transport top should match guide ridge down length of bridge (Up-Down Height). If still adjustment required, repeat the above steps Figure 3 to Figure 4, till the proper Height adjustment is achieved.
Once the adjustment is complete, fix back the Scissor covers to the table.
