We have got a 10 ton 4 post Zippo lift which is German and a 6 ton Somers two post mobile lift. We would not be without them it just makes things so much easier especially when working on big compact machines like Hyster S7.00's.
The mobile lift is also good as it a wheel free design so you can do brakes etc standing.
Whoever said about parking trucks under though has obviously never used one as there is not enough clearance underneath!!
