Not sure who made the NZ ones but have seen them in operation years ago. They must be long in the tooth now but may have been locally engineered as haven't seen them elsewhere . Fair bit of common sense and simplicity in their design. It is a harsh role but at least they are doing it on a solid flat port environment .

I guess people just don't appreciate what a difference good design makes and Aussies and Kiwis have a reputation for thinking outside the box . Long may it continue and we score some more innovations but often hard to get reward for and retain IP .

Plough - you in USA at minute as I had a favour to ask - would like some photos of some aussie items in a supermarket ?
