Engine lift - Where do the small wheels go

[Spetz]

Hi guys,

I am assembling a foldable engine lift crane similar to this:

It has 6 wheels.
4 large, 2 small.

So when the engine will be on it only 4 wheels will touch the ground.

So where do the small wheels go? (they are all caster wheels).

I see in pictures it looks like they go in the middle, meaning that the rear most and front most wheels will be on the ground which makes sense for balance.
But I thought perhaps the front should get the small wheels to easier get under the car?

Middle. On the short legs, so that when the long legs are folded down, the four points of contact are the four corners of the lift.

If you put the smaller wheels at the end of those legs, then the hoist could wobble or be unstable with an engine on it.

Which would be really bad...

They go in the middle, Their only function is to be able to move the hoist when the legs are folded up
