Don Jackson | Trolley | Repair | Video Trolley Failed in Cyclotron Tank |
All control to the video trolley was lost during remote photographing of components in the cyclotron. The control system and cameras on the trolley were still operational leading to the suspicion that a power cable was broken either on the trolley or the bridge festooning. Two trips into the tank were made to evaluate the problem and attempt to push the trolley out of the tank. Pushing the trolley only managed to move the trolley a few feet before jamming. A lift mechanism was used to raise the drive wheel without any success. This device was modified and used successfully to remove trolley completely from the tank.
Three trips by two persons were required to remove the trolley. There was a total dose of 0.5 mSv was received by the two persons going into the tank. An additional 0.18mSv was receive by 3 persons outside of the tank.
The trolley will not be used in the cyclotron until the problem is diagnosed and repaired. This trolley is not critical to any upcoming remote handling operations. |

Adam Newsome | Trolley | Repair | Video Trolley Mk 1 - Radial Limit Switch Replacement |
An issue was observed in which radial motion on the Video Trolley Mk 1 did not respond to commands. After troubleshooting, it was determined that this was due to the "OP LIMIT" interlock - the "OP LIMIT" pushbutton on the console was illuminated in red, and needed to be continuously held down in order to operate the radial in/out motion buttons.
It was determined that the root cause of the issue was a failed radial limit switch which was likely damaged during trolley transport. The limit switch was replaced, and functionality was restored. |
