That hoist you have looks very similar to the one the late John Prins had at Tanganyika automotive engineering when I worked for him 42years ago,the locking rails with dropping ramps was great for suspension or brake work while vehicle on hoist.yes his was European made but can’t remember the brand name.should be a good thing for you Shane when it’s up and running….jimi've worked out what the scrap metal I've purchased is .... That took something searching of the internet. The previous owner never worked it out and said he thinks its german.
this is the exact thing here looking at the power post.
For Sale 240v 4 Post Car Lift/Ramp - RIBnet Forums
Bradbury 4 post car ramp. The same as in the pics below, it's 240v and in very good working condition. It has wheel free too The ramp is all up and running and can be seen working. Open to sensiblewww.rib.net
This is how it works.
just as the seller described, the ramps drop away allowing the car to be suspended. I honestly don't know if that will be much use, I'll see I guess. Another project that I'll waste lots of time and money on no doubt
