Jacking up a carrier

[universalgrl]

Some important things to consider when undergoing jacking operations take your time and do it right!
1. Always jack on a level surface preferably concrete.
2. Check your equipment for faults.
i. jack stands for cracks or missing floor pads
ii. hydraulic jacks for proper fluid level and leaking seals
iii. make sure the jack has sufficient capacity to handle the load.
3. If you are jacking a carrier that does not have a center divider make sure that the hull sits level and do a cross corner alignment check before any serious riveting work is undertaken. A small misalignment error at the bottom can equal a large error at the top.
If you think I am preaching, I was a general safety officer and I have seen jacks collapse after blowing their seals, jack stands crack and collapse and cars fall off hydraulic hoists.
