Greetings and Salutations, Everyone:
Name is Paul from Toronto, Canada; love this board; the 12g Garage led me to GJ. Mostly a lurker on here, haven't posted much before.
Recently picked up a decent condition older Nussbaum Jumbo NT 7000# double platform 7 ft scissor lift, made in Germany. It came out of a Mercedes Benz dealership. One of my Foxbody Mustang friends works in the hoist service industry, so he hooked me up. It's an older machine that he had rebuilt the two primary cylinder on. Took six of us to move them, they're app 1100 # each. I figured out a few tricks later on, when I moved them into position in my car shelter (!) by myself. Had to do the hydraulic hose ends ID and layout and then order the hydraulic hoses and 4 adaptor connectors in order to flip everything to JIC -4 or -6. Had to make a plug for the 240V and grab 4 gallons of hydraulic fluid and screw around with a few other things including manually lifting one platform to 4 ft in order to be able to remove a hose from one cylinder. Spent a whole day on this, incl running out to grab a 60" Farm Jack, which ended up working in tandem with my snowmobile crane. Then it took us only about 3 hrs and several beers one afternoon at around 25*F to connect everything, bleed and sync the platforms, etc. All told, it cost me about the same as a new 7000 # Quick Jack.
This setup will now lift my convertible Fox over 40" into the air; once I slide the overhead lights a foot outbound, it will be an honest 4 ft; high enough to do oil changes and anything underneath on a rolling seat.
Awesome and pleasant surprise!
Had to put down 6 large patio stones so the car can get up, on and over the platforms, which are 4-1/2" above the surface. Since the shelter is only app 9 ft across inside, I played around with a sketch and scaled cutouts to determine the position of the hoist in relation to the car and the shelter. Still have app 2ft of walkaround space on the sides and app 1 ft at the entrance, so the space in front of the car (closest to the garage/tools) is maximized for access and tool carts. The platforms are 2 ft wide and are positioned app 2 feet apart. That is about the min space for below access and still positions the lifting points about 8 inches from the inside. Can reposition them if needed, since the hoses are nice and long. Currently, 4 pieces of 2x4 lie flat on the platforms under the subframe connectors under the floor of the car.
Works perfectly, is even relatively quiet and a German example of engineering and packaging. We lifted them to their full 7 ft height while bleeding them, marvelous, really. Only downside is they're not designed to keep vehicles in the air for long periods of time, since they're hydraulic locking, not mechanical like most cable equipped lifts.
Will work around that, since the car is finally drivable after 5 yrs of work.
Yes; having a lift inside a car shelter is totally Ghetto Garage....... but my 1.5 car garage is full of tools, equipment and work benches......and .....beggars can't be choosers......
Here are some pics (and two vids, if I can unload them) of the whole scenario.
