This custom made ramp:
It was made for my dog when he had an injury to his knee, unfortunatly it was not practial for me to handle.
It was custom made by a local engineer to a very good standard, it weighs about 30lbs [15kgs] & measures W 27/12″ [70cm] L 60″ [152.5cm] & when folded W27″ x 32″ x 4″ deep.
I payed £300 & would accept £150 or v.n.o.
It is made from aluminium checker plate for a non-slip finish.
