The primary transfer flask was inspected on the 26th of June, 2024:

1. Electrical cabling and connections externally mounted on the flask + on the hook/latch were inspected for wear, damage, proper connections,etc.
   • It was learned that the controls+power cable that drives the latch also runs the height indicator pulley+lead weight system, this should be reworked in the future and replaced with proper load bearing rope/cable.
   • The cable connecting to the main control box was duct-taped heavily, it may be a good idea to replace it with proper reinforcement in the future.
   • The power cable connection to the grey junction box is not terminated properly and should be re-terminated (some other cables may need to be re-terminated properly).
2. Various markings on the exterior of the flask were checked:
   • Marks on the flask flange were still visible
   • Marks on the flask body for reference flask orientation were still visible
   • The weight of the flask (30,000 lbs) had faded and was written over with a sharpie (it may still be a good idea to paint a larger version of the weight so that it is visible by the crane operator)
3. Limit switches throughout the flask was inspected
   • The chain hoist limit switches were tested and both functioned properly, some wear was observed on the spring toggle for the upper limit switch but it does not need to be replaced yet.
   • The limit switches on the hook/latch were tested and functioned properly, with the exception of the 'unlatch' limit switch which we could not test because the unlatch indicator light on the control was broken (this should be re-tested in the future).
4. Rolling/rotating components (pulleys for the door and level indicator, guide wheels inside the flask,  door pin/hinge, main lifting eye, hook latch) were inspected
   • A retaining ring was missing from one of the level indicator pulleys which was promptly replaced
   • All other pins/shafts/rollers were in visually in good condition and rolled properly (despite some being rusty) and had proper retaining components (cotter pins, retaining rings, etc.).
   • Note that for future inspections, it may be a good idea to manually move the various rollers to check by hand if the pins/shafts need to be lubricated
   • Also, the lead weight driving the level indicator should be painted over, and a sacrificial contact pad should be used to prevent the load from wearing the outside of the flask
5. Electrical assemblies inside the control and grey junction boxes were inspected and found to be in good condition
   • *Except for a broken LED for the unlatch limit switch in the main control box (the broken LED issue was sourced to a broken relay that was promptly replaced, the unlatch status light shows up now)
   • All hook/latch actuating switches on the control box seemed to be working (note that the finger-related switches were not tested)
   • Note that there is an 'override' button on the control box whose purpose is unclear, we should investigate this to determine its purpose in the future
   • Note that to access the internals of the control box, only the two central screws along the white line need to be removed
6. The chain hoist and cable pulley system for flask door were inspected
   • The chain lubrication seemed dry, it would be a good idea to re-lubricate the chain properly and perform some form of maintenance on the hoist in the future
   • The chain length is retracted and dropped from a bucket and currently causes the chain to rub against a corner on top of the flask, in the future it may be a good idea to make some changes to avoid this
   • The flask door cables used duct tape to prevent the crimped cable loops from fraying and was still in good condition
   • In the future, we may want to look into the cables' channel to check for fraying or damage along their length.
7. Inspect main flask structure
   • Welds on and around the main lifting eye were in good condition without chipping paint
   • There was visible deformation on the lifting eye from contact with the hook, but this should be no cause for concern, and besides this, no signs of wear/damage was found on the lifting structure
   • The external welds on the main flask body were in good condition
   • The welds on the hook/latch that we could see were in good condition and still fully painted
   • There was some rusting on the platform
   • The welds on the ladder and platform were of lesser quality than the lifting structure but no cracks or broken welds were found
   • In the future, we should determine a weight limit for the platform based on some analysis
8. The aluminum tray was inspected and found to be in good condition, however we should replace the old rubber pieces with new ones at some point
9. The drive mechanism for the doors/hook/latch was tested and we were able to travel the full distance without abnormal sounds from the chain hoist.
10. Seismic clamps were inspected and the bolts + threaded inserts were re-tapped and greased for smoother disassembly/installation.

In addition to the items above, the four 'fingers'/actuators that are holstered by the base of the flask was inspected visually, we will confirm their function before determining whether they need regular inspection/maintenance.

Also, at some point we should inspect the target alignment frames, their camera systems, as well as hot cell flask controls systems.
