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.
