Lifting a Vehicle over a Pit

[RetroPug]

Ah yes, I forgot to discuss jacking beams in the OP. You can buy them, but they are expensive, and I'd have to lie on the floor and reach into the pit to operate it under the car somehow as I cannot get in there when there is a vehicle above it. Also, that would be resting on the edges of the pit, which is a DIY build by a previous owner. It looks solid but I'm not sure I'd want 50% of the vehicles weight on the edges of it with me sitting inside it. There'd be a risk of collapse.
