  2505   Thursday, November 23, 2023, 11:15 Adam NewsomeCraneRepair  Target Hall Crane: CW/CCW rotation mechanism failure [tripped breaker]

It is reported that the crane's hook rotation is not working currently. It was working yesterday (Nov 22). Investigation to follow, and this e-log will be updated.

Edit [2023-11-23]: the issue was a result of a tripped circuit breaker. Perhaps the motor became overloaded. It is advised to monitor the rotation mechanism over the new few operations, and rotate the hook CW and CCW prior to performing any critical operation to confirm it is working.

Hello all,

During our planned operation of transporting TM4 from a storage silo to the Hot Cell, we had a problem with the East-West bridge drive on the Target Hall crane.  The crane bridge is currently stuck in position over the silo area.  We were unable to complete the transport operation.  TM4 has been placed back down into the silo and the crane hook block has been disconnected from the module lifting yoke.

We have been on the phone with Norelco this afternoon and have determined the likely cause of the problem.  There is a splice joint in the crane rails at this position, where a small gap exists between the rail sections.  If the crane bridge is stopped during operation such that the wheel comes to rests in this gap, the crane motors have insufficient torque for the wheel to overcome the gap and ride back onto the rail.  The Norelco tech Mike Smith remembers encountering this problem several years ago (before my time) but cannot remember how it was overcome.  The fix likely involved moving the wheel out of the gap with pry bars.

Target Hall Survey Needed at or before 7:00 am, Wednesday Oct 9th (Lynne, Fiona, Danka, Max or Dano?)

Mike Smith and possibly a few others from Norelco will come tomorrow morning at 7:00am, and require access to the Target Hall.  Since we have opened the Hot Cell in preparation for the module move, we will need a survey as early as possible to allow Mike and his crew to enter the hall without a suit and respirator.

Most of the Remote Handling group will be off-site for a Division meeting, but Travis and Maico will stay for the day to accompany the Norelco guys and help with the problem assessment.

Travis: Please take Mike to the control room when he arrives, one of the cameras is currently zoomed in on the wheel and problem rail section.

Maico: Scaffolding may be required to get access to the crane rail.  Unfortunately we don't have an operational crane to transport a man-lift into the hall ;)  Please see what you can do to get this ready in case we need it.  Max's leak check might have to go on hold until we get this resolved.  Please take responsibility for ensuring correct Fall Protection procedures are followed.  This means that nobody should be walking up on the crane rail unless they are tied in with harnesses, or there is scaffolding directly under them.

I can be reached on my cell phone at 778-319-4612.  The Division meeting is on UBC campus so I can return to TRIUMF fairly quickly if needed.

Thank you all for your assistance,

Grant

E-mail from today:

Hello Dave, Jane, Franco, Michael, Don (controls + Franco), Remy,

We have lost the East-West bridge drive control functionality of the ISAC Target Hall crane, and unfortunately this very much prevents us from operating the ISAC facility.

The problem was originally thought to be a stuck bridge wheel but this was not actually the case.

Mike Smith from Norelco was on-site for most of today working with Michael Rowe in an attempt to diagnose the problem.

Mike believes the problem to be one of the following three items:
- input PLC board on the crane bridge
- output PLC board in the interface panel in B1 level Room 5 (ISAC remote crane control room)
- communication between the two boards (festooning hardware)

We are in a pretty dire situation without the ISAC target hall crane, and we lack the expertise within the Remote Handling group in PLC hardware to diagnose this on our own.  I need to ask for somebody's help from the controls group in diagnosing and repairing this problem.

I have notes from my telephone conversation with Mike Smith which I can discuss with a controls representative in the morning.  There is a pretty muddled history of the design and implementation of these controls but essentially Norelco outsourced the PLCs and festooning to a third party contractor, Seattle Crane in the US, which no longer exists anymore.  Neither Kone, Seattle Crane, or Norelco made appropriate as-built drawings of the wiring of the PLCs.  Mike Smith at Norelco had a stack of hand-written notes about the as-built configuration he made at the time of installation in the late 1990's but these notes have not been located yet.

The PLCs appear to be Allan Bradley but the modules are from approximately 1997 and we're not sure if spare units are available.

Mike Smith says the easiest thing to do at this point is install replacement PLC modules on the crane bridge and in the control room that have confirmed functionality.  If control is not restored then the problem is likely in the festooning.

Control of the crane bridge was temporarily attained by bypassing the controls (speed control / end limits, etc.) and sending drive signal directly to the drive motor controller in order to return the bridge to its home position at the access ladder.  This mode of operation is not safe as the crane has no speed reduction / limits to prevent driving the bridge into the walls at max speed.

Jane / Remy / Franco: please let me know who I should correspond with on the controls side and I will talk with them tomorrow morning.

Thanks,

Grant

  2040   Friday, January 03, 2020, 13:15 Adam NewsomeCraneRepair  Target Hall Crane PLC Module/Battery Replacement
The Target Hall Crane bridge and trolley motion was lost after a period of the crane having power disconnected over winter holidays. This is reported in the following e-log: https://elog.triumf.ca/TIS/RH-ISAC/2039. This issue is a duplicate of what happened in 2019 at this time: https://elog.triumf.ca/TIS/RH-ISAC/1845

It was determined from troubleshooting via PLC indicator lights that the memory battery had died during the power-off time, and because of this, the program stored was lost. Note that this is an anomaly - the battery should have lasted much longer than the shutoff duration of ~2 weeks.

The SLC500 module was replaced with a spare, which contained a new battery. The old SLC500 module is still functioning but the battery has been removed (spares will be ordered) - this module is stored in a cabinet drawer in the control room. It will need to be re-programmed if re-installed as the program was lost. The original program titled TargetHallCrane.RSS was downloaded to the module. The crane was tested in local mode and determined to be functioning.

Hi Curtis

 

Further to the emergency service call at the Isac Target Hall on Thursday March 23rd, we advise as follows:

 

It was reported that the hoist was making an unusual noise and that there was a strong brake odour during operation.

The lift was completed using the auxiliary hoist.

 

A man-lift was arranged and Senior Service Technician Tom Kauss attended site the next morning to troubleshoot.

He determined that one of two hoist brakes (walkway side) had a strong odour and on closer examination it appeared that the 

brake lining material was breaking down and particulate lining material was getting caught between the lining and the discs.

These lining fragments were rubbing and burning off during the hoist operation.

The end cover of the brake had an accumulation of brake lining fragments 

The lining was not overly worn, but appears to be becoming friable, perhaps with age or exposure to radiation.

 

The brake was cleaned with compressed air to remove the friable material and thoroughly tested. 

A test load of approximately 10 tons was lifted and the hoist handled the load without issue

The brake fragment issue did not recur while we on site and the hoist was recommissioned for use.

 

To guard against the likely recurrence of this condition on this critical application crane, and as both brakes have seen identical conditions in operation, 

we recommend that both brake assemblies be replaced.

The brake assembly would include the brake coil, friction discs, steel brake discs and the brake springs

TRIUMF does not have a spare brake on hand, therefore one of the removed brakes could be rebuilt and kept on hand.
