I think I need to get myself one of those - it'll need to be portable as I'll have to drag it from the back of the garden to the front drive, but would certainly save my back and knees....
The pump trolley on mine (picture link to source above) has a hook which allows the main ramp to be jacked up to provide movement. Given the considerable weight to allow 2.7 ton lift capacity, not as an everyday occurrence though. Mine lives in the same place on garage floor with stainless plates for ramps rear wheels to ride on during scissor action. Morton sits over it when not in use.
