Actually it is the same make as the Reef Diver at Dreamworld.
I was working there when we pulled the old Enterprise out which went to Downunder Land in Canberra and sat in the back paddock. It should have been scrapped!
I think the Reef Diver was brought in from a defunct park somewhere in Asia and got a full overhaul and paint job before we installed it into the park.
All the operators loved the Reef Divers automatic doors rather than the old Enterprises doors having to be opened and closed by hand, which really sucked on busy days when you had to do every car. Made the load and unload time so much shorter.
that enterprise is a basic copy of the HUSS one (notice the placement of the hydraulic ram - reef diver's is positioned different and stays a lot closer to the main support arm). However this is not the only knock-off. They are also being made in Italy (identical HUSS clones) see here: http://www.youtube.com/watch?v=tIvy4pbVcq0
...they say immitation is the greatest form of flattery?
