Pneumatic lifting

[BobJ]

We want to be able to move a heavy platform quickly and easily. Sometime back I was given some details of suppliers of pneumatic equipment we could use to "force down some wheels for the move. I lost all those notes! Ideas welcome.

I thought the usual practice was that the truck rides on the wheels the whole time; and the pneumatics push down feet to lock it in position- am I wrong?

I think it is really down to the designer: for the show I saw it done they needed a set piece to be very low to the ground and very stable, so it made sense for the wheels to retract/extend. The set piece had a CO2 cylinder inside of it which provided the pressure to run the system, which was controlled using disguised buttons on the outside of it.

Totally awesome. Thank you. I'm off hunting

That's a counter-intuitive way of doing it - you should use the power for the shortest amount of time so since most trucks spend 99% of their life /not/ moving it follows that you should use the lift system to engage the wheels for moving so that for 99% of the time you are not using up power.

 

Obviously if it's a truck that's in constant motion and only very occasionally sits still then it might make sense to put the locking legs on air but that would be a very rare circumstance
