|
Last Friday, During the crane per use check, I found the main power supply to to crane was shut off. I was told Don and Travis shut off the main
power before Triumf power outage. Travis restored crane main power and I could turn on the main relay on radio pedant in TH. But, I didnt
have all crane main bridge movement controls on TH raido pedant except rotation. I still have all movement controls on small trolley from the radio pedant. |

|
Gordon crane technician started TH crane trouble shooting this morning. The problem is found that there is no 115VAC power supply to energize a
main coil which is used to switch on 450V AC power supply to crane. He did a test and found the crane could be operated by big yellow pedant
in control room when he manually gave the coil 115VAC power supply to energize it.. At that moment, the crane is set to big yellow pedant operating mode. |

Gordon crane technicians continued their troubleshooting on this Tuesday. They found the crane up-limit protection switch which is installed on the same
bracket with the the crane down view camera is broken. The spring inside the limit switch which is used for pushing the action plunge out in the
switch lost its function. This up limit switch is the last protection for the crane so it is set as when it is in action the crane main contact coil |

Strange noise and a burning brake type smell was observed yesterday by David and Anders when running the main 20 ton hoist locally. A service call
was arranged today with Gordon Crane. No major issues were found. A more detailed summary is in the attached e-mail correspondence. Gordon
Crane will issue a formal report, but they recommend replacing both sets of brake disks and brake calipers. - Grant |

|
Today, I checked TH crane main hoist when shielding plug is installed into ITE pit. I did some jogging actions on main hoist during the operation.
Everything looks fine. No burning smell, no strange noise. An outside crane expert suggest that jogging is the worst working situation for crane. We have
to use jogging actions during our crane operation. But, we could try to use less jogging when operate the crane. |

Gordon Crane technician Tom Kauss finished the replacement of the east side main hoist brake assembly. A new set up is installed. he adjusted gap too
close during first time try. So, the smell appeared when operate the brake. He increased the gap to a proper distance then. It looks like everything works
fine now. Still, The brake need to be tested with 10K lBS load on it. We will do the load test on next Thursday when he come here to replace west side |

Monday, May 01, 2017, 12:32, David Wang, Crane, Repair, , , TH crane burning smell
|
TH crane burning smell showed again this morning. It appeared after 1-1.5 hours of continuously using during the F308 flasks moving in TH.After a certain
time of using I think the brake gap is reduced because of thermal expansion. The main hoist and brakes work fine still. We knew these brakes gap
are tight especially on west side. So, It is not surprised that this burning smell appeared again. It does not affect the safe of crane use in my view. |

TH crane is used for transferring five shielding blocks(30000lbs) today. All brakes work fine. Mostly, I do not need crane slow up motion for
this job so during 1 hour moving, no rattle sound and burning smell has been found. I think TH crane is good to use as we decided. |

This morning, when I prepare for today's crane check, The crane made a very strong noise without any load during the full speed up motion. I stopped
the crane right away, and noticed that east side of main hoist motor area was smoking . The crane was moved to east end. And, I climbed up to the top,
and found the smoke is coming form brake side, and should be produced by braking. The smell is same as before.Unless other thing is wrong, I think |

Gordon crane technician Peter came in today and checked TH crane. Maico and I were there with him. What he found is that brake gap on both side of
main hoist decreased after months of using. The solution is to lock the automatic self adjustment system so the gap will be fixed there. Each year
during annual inspection, they will adjust the gap manually. After he locked both side of device, I tested the crane up and down couple of times. The |

Earlier in the day it was noted that the rotate function of the crane had creased operation. After David has finished the block moves. Don and
I checked the Crane's control unit in the ISAC crane control room and found the breaker tripped for the rotation. The breaker was reset and the crane's
rotation is now operational. If this occurs in the future only Travis Cave, Don Jackson or a TRIUMF Electrician are allowed in that control box as it is |
