Lifted 3 chambers out of the basement and put them on the ISU, temp controlled, loading dock.
1/8/14
Loaded truck for shipment to JLab.
1/13/14
3 chambers arrived at JLab and were unloaded. No obvious damage was reported.
- Lessons for the next shipment
- trim crate at least 1/2" so there is more space between the trailer wall and the crate. The 91" inch pallets were fine, need to cut a little straighter as a matter of pride and to make it easier to push onto the trailer.
- be sure to cut out a section of the 3x3s so there is room for a pallet jack.
- be sure white pallet drift chamber wheel blocks are at the proper locations so the chambers are aligned with the pallet. Distance between blocks is less important since U-bolts holding the front wheel can be moved back, but not forward. Error may only be accommodated if the space between the front block and rear is shorter than needed.
- Be sure to lift pallets with crane when pallets can't fit through the elevator
- Continue to stage drift chamber on the loading dock, the other pallets can be placed outside, may need to secure a location for the other pallets that contain the A-frames, magnets, and other stuff, the non-drift chamber items can be shipped in a separate shipment.
