If that was me on a budget I'd use a sheet or thick steel/chequer plater etc to slide over the end of the pit, then slip a low entry jack under and jack entire front or rear up, if you place a good full size jack under the subframe or rear beam you can lift both wheels off with one jacking action quite safely.
Only in for ~£100 then.
And agree, I would not be using a jacking beam on anything other than the metal edges of a ramp designed for it.
