i use those scissor jacks to raise up the floor in my old house,works great,, too much weight will ruin the threads,did that fixing a flat on a single axle trailer that was loaded,..they do make larger ones for one ton trucks here in the USA, mine has a 2:1 gear reduction.keep it in my 1/2 ton 4X4,slow to use,but will lift anything i need it too.
