Friday, February 18, 2022, 09:26, Adam Newsome, T-Hall Crane, Maintenance, Potential grease leak observed
|
Naimat Khan noticed after using the crane that some grease dropped onto a spreader bar, and believes it is a leak from the main hoist (see attached photo).
The hoist should be inspected.

Monday, January 25, 2016, 13:20, Allon Messenberg, T-Hall Crane, Maintenance, Possible oil leak
|
Two small (approx. 5 cm across) puddles of green fluid were discovered on the floor, directly below the crane trolley. The hook block was lowered
and inspected. No fluid found on hook block.
The plant group (Neil Wong) was notified and asked to schedule an inspection when the maintenance crew is on site to inspect the ISAC target hall |

Friday, January 20, 2023, 14:48, Adam Newsome, T-Hall Crane, Standard Operation, Pendant/Receiver Communication Issue (Repeated)
|
An issue was observed in which the pendant did not work to control the crane. This is the second time in recent memory this has happened. See e-log
55 for details. The same sequence of steps outlined in e-log 55 was followed, and the pendant control was re-established. It is still unclear what
the root cause of this issue is, but it is suspected that the crane pendant loses communication with the receiver for some reason, and even though communication |
Wednesday, August 24, 2022, 13:47, Adam Newsome, T-Hall Crane, Standard Operation, Pendant/Receiver Communication Issue
|
In preparing to troubleshoot the issue described in e-log #54, the crane was power cycled, and the pendant battery removed, to get to a "fresh start"
state. Prior to this, the crane functioned normally aside from the incorrect E/W direction control on the North Aux Hoist.
Upon powering the crane back on, the pendant did not work to control the crane in any mode. The HMI had a fault present which read "305. Radio |
Tuesday, December 20, 2022, 10:03, Adam Newsome, T-Hall Crane, Standard Operation, Overhead crane powered off for the holidays
|
[edit 2023-01-03] The crane was powered back on this morning - there do not appear to be any faults on the HMI and it seems that the crane was unaffected
by the power outage.
The ARIEL target hall overhead crane was powered off for the holidays. In the new year, throw the main disconnect in the crane control room to |
Friday, July 03, 2020, 15:43, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist: West Travel Motion Failure
|
An issue was observed in which the North Aux hoist failed to travel West when commanded to, but the East motion was functioning. The North Aux hoist
Trolley was stuck in a position up against the East wall.
Present during troubleshooting: Adam N, Maico D, Tom K, Allon M, Travis C |
Tuesday, March 15, 2022, 10:03, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist VFD Replaced
|
The North Aux Hoist VFD which had failed (e-log 50) was replaced today by Tom Kauss and Adam Newsome on Work Permit A2022-03-15-1.
The hoist's motions were all tested - it is functioning normally again. |
Wednesday, September 09, 2020, 10:51, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist Replacement (followup on E-Log 44)
|
See E-Log 44 for details on North Aux Hoist failure.
A replacement VFD was ordered by Adam Newsome and installed by Tom Kauss.
Adam and Tom replaced the VFD in the South Aux hoist (which had been relocated to the North Aux hoist). The original braking resistor was used. |
Tuesday, August 23, 2022, 10:32, Adam Newsome, T-Hall Crane, Maintenance, North Aux Hoist - reverse motion axes on E/W
|
Update 2022-10-06: During routine inspection of the crane, Tom Kauss investigated the direction swap issue. It was determined that there was
likely an issue with the initial installation of the new VFD back in March 2022, and that it was unnoticed (directional control wires crossed). The issue
has been resolved by Tom Kauss and is no longer a concern. |
Tuesday, February 01, 2022, 08:29, Adam Newsome, T-Hall Crane, Repair, North Aux Hoist - West Motion Failure
|
An issue was observed in which the North Aux hoist failed to travel West when commanded to, but the East motion was functioning. The up/down motion
was also functioning. The North Aux Hoist Trolley failed during regular usage, seemingly randomly, when it was about 70% towards the West end of travel.
Note that the West motion VFD inside the North Aux Hoist is the one previously taken from the South Aux Hoist (the same issue with the North Aux Hoist |
Thursday, January 06, 2022, 10:46, Adam Newsome, T-Hall Crane, Development, Modification of South Limits
|
Edit: as of May 30, 2022, the modification has been reversed, and the crane is functioning normally as per the manufacturer's limits.
Modifications have been made to the crane to allow for the South Aux Hoist to reach closer to the South wall during the ARIEL Hot Cell installation |
Friday, December 05, 2014, 10:43, Isaac Earle, 100KW Beam Dump, Development, Lower Lead Shield Drain Line Installed
|
A 1/8" SS tube was routed from the Swagelok fitting on the front of the lower lead shield to the service stand water catch tray as shown in the
attached photos.
The tube was routed to fit in the cut-out and chamfered corner gaps of block TSH0387 in the de-rated EHDT shielding assembly TSH0293. |
Friday, March 20, 2015, 11:45, Isaac Earle, 100KW Beam Dump, Development, Lower Half of BD EHDT Shielding Installed
|
The lower half of the beam dump EHDT shielding was installed yesterday by Plant Group. After installation of the service stand plug, the
position of the south and east faces of the plug were checked with the laser tracker w.r.t. EHAT MB4. The south face was within approximately 2mm
of nominal, and the east face was approximately 6mm east of nominal position. It was decided that this positioning was acceptable. The modified |
Tuesday, November 23, 2021, 11:01, Adam Newsome, T-Hall Crane, Repair, Load Cell - Not Functioning
|
The load cell which is located on the crane itself to display the load to operators was reported not working during the week of November 15. It is planned
to investigate on Nov. 25 and this e-log will be updated with the status.

Wednesday, August 02, 2023, 09:13, chad fisher, Hot Cell 1, Repair, Leak Rate Testing
|
On August 1, 2023 HC1 was pumped down to -1200 Pa (gauge) and then valved off to test the leak rate after turntables had been sealed with backer rod
in the gaps.
The sealing with backer rod allowed the cell to reach the test pressure of 1000 Pa. The cell pressure equalized within 30-40 seconds which is an |

|
On Tuesday, February 14th I finished modifying Jason's boxes for the remote crane tests by adding shelves to mount cameras... Apart from given the edges
a quick sanding (so no one gets slivers)...which I will try and do tomorrow. |

|
Background: On 2019-06-25 a Pri VelFdbk Loss fault was discovered on the Main Hoist East Drum South Motor of the ARIEL Target Hall Crane. The crane was
used previously on 2018-08-22 without incident. The main hoist of the crane was unavailable until the Hugo Lapointe (Automation Technician) from the crane
manufacturer (REEL-COH) replaced the Allen-Bradley 20-750-ENC-1 Incremental Encoder board in the 800VFD with a new one, and replaced the Motrona cross |
