Hi Ironbark,
the powered jockey wheels have plenty of power it is getting the traction that might be a problem on uneven ground or loose gravel surfaces. Over the years I had thought of winching stuff up the stairs, sand,screenings,scoria etc up into the back yard but whinching and chainblocking are slow and tedious so I had never got around to going that path. The jockey wheel is slow but that is not an issue when it is climbing and once on flat ground I lower it back onto the casters and can push it around as a normal trolley
