chad fisher | Elevation Jack | Maintenance | Checking for contamination on fall arrest equip. |
Fall equipment from the lockers in the RH shop have been checked for contamination and the lockers themselves have been swiped. All items checked in the target hall cave.
No contamination found.
Upon discussion with Dan it was mentioned the harness that I used was not used in the vault, and its origin is of question at this point. |

chad fisher | Elevation Jack | Maintenance | Contaminated equipment update |
The harness, carabineer, and shock packed used during the ISAC hot cell swipe have been checked seperately by Mike and he has found that the carabineer was active (feild of ~3 uSv/h on contact) not contaminated. All other components are clean and non active.
The assumption being that this carabineer most have come from the cyclotron vault. |

maicodallavalle | Elevation Jack | Maintenance | 2012 Service Maintance of #4 Station Jacking System |
Shut down work for 2012.Replaced serviced Jacking Station #6. Tapered alignment pins were damaged. They were skimmed and checked and installed. Station #4 was removed and the spare Station was put in its place.Station # 4 Upper Bearing was inspected and serviced.Station #4 had a problem with the Jack on the right side.The coupling hub than joins the Jack to the High Field was installed backwards.(Not sure how long the hub has been like this maybe 15-20 years?). The coupling and hub had to be cut/split apart to get them off of the Jacks shaft. A new coupling and hub was machined and installed. Anew shaft seal was installed next to the new coupling hub. All the old grease was removed from the Jack. The Jack was inspected and then new grease was replaced. The left Jack was also serviced. It was taken apart and the old grease was removed. The Jack was inspected. The shaft seal on the other side of the coupling hub was replaced. New grease was replaced. The two High Fields had the oil drained. They were inspected and new oil was replaced. #4 Stations motor has four mounting bolt holes and two tapered pin holes for alignment. The one tapered pin hole in the front right side of the motor had a small hairline crack. The paint was removed in the area where the crack was so it could be welded.(The motor base is made of Cast Iron). The crack was welded with 309L SS welding rod. After welding the tapered pin hole was checked with the tapered pin.(It was OK). The #4 motor was bolted to the service area work bench. An Electrician hooked the motor up for testing. The motor was greased and then it was started. It ran nice and smooth. |

maicodallavalle | Service Bridge | Repair | Service Bridge/Carrier Hydraulic Jacks |
On Monday February 4TH the Service Bridge was being lifted into the Cyclotron with the Carrier. It was noticed that one of the two Hydraulic Jacks was leaking. All work stopped and the Service Bridge and Carrier were moved to the Remote Handling B2 level for repair. The Service Bridge and Carrier were separated and the Hydraulic Jacks were inspected. It was noticed that both Hydraulic Jacks were leaking. Two overhaul kits were ordered. Two other Hydraulic Jacks were found and replaced. Work continued in the Cyclotron with the Bridge and Carrier. The two Leaking Hydraulic Jacks were overhauled. Once most of the work in the Cyclotron was done and there was time that the Service Bridge and Carrier were out of the Cyclotron and not in use the two overhauled Hydraulic Jacks would be replaced. They were tested without the Service Bridge and then with the Service Bridge. There were no leaks and all operation was back to normal. |
