My friends is older than I am and very arthritic. In his workshop he has two hydraulic lifts. One for cars, A GMC suburban and lawn tractors (6,000#) and the other for his motorcycle.
When I help him with projects I am always amazed at how much easier it is to work on machinery when you can get it to the right height.
Recently we replaced the drive shaft on a TG1860 which necessitated removing body work as it was impossible to reach the shaft.
On the motorcycle lift we installed new chain and sprockets on a 450 Honda + new brakes. Again, sitting in a chair beside the elevated motorcycle was easy compared to my shop where I am lying on the floor. Getting down on the floor is hard. Getting back up is next to impossible.
Both lifts are easily moved around the shop so they are not permanently using space. The bigger lift he found at a bargain price because it had a 50 cycle electric motor. I felt it would run on Canada's 60 cycle power and it has for years.
