I made this motorlift with the plans i got from a friend. For mine i changed it a bit , mine is longer and higher than shown in the plans. It can easily lift my motorbike which ways about 170 kilo. I also use it a lot as an extra workbench.
Lock mechanism for the table. It's low is 150mm and can rise up to 920mm.
