Portacabin Jacklegs

[Wendelspanswick]

Any idea how the jacklegs on a Portacabin work?
Is it just a screw and nut or something more involved.

thort they are like axle stands a sliding leg with holes at different heights and through pins

I thought you could use them to load and unload from lorry backs?

The buggers can seize.
Use a couple of bottle jacks, life the leg up with 2. So it is free of The ground.
A few deft blows will see the leg drop.

I was hoping I could fit some to the habitation box on my lorry to mount and dismount it.

 

[Wendelspanswick]

Not quite as drastic as this but a similar idea.

4x legs, a farm jack and a bit of elbow grease!

 

[gaz1]

they use the same principle

Mine are two concentric heavy wall steel tubes, the outer (=upper) part has a heavy bracket welded on the side. The inner (=lower) has a broad foot welded on it's base. A pin goes through both tubes to stop them sliding, with holes drilled every 2 inches. By placing a jack between the foot and the bracket, and taking the strain you can remove the pin, jack up or lower, and select another hole for the pin.

That is so long as some plonker hasn't inserted the pin from the wrong side, so when the jack is in place you can't pull the pin out

(Ask me how I know )

That makes sense, thank you.
