Gas cages.

Apologies if this is in the wrong place please advise and I will move it.

My question is this,
I am having a big issue with Gas cages on sites I am running, they are really heavy and are really built for moving around with a fork lift truck.

As my sites rarely have a fork lift truck it becomes an absolute pain taking them down and trying to get two of them back onto the hire wagon.

The hire company don't seem to have the correct trucks to deliver these units or collect them and they are giving me little help in sorting my issue.

So my question is are there light weight gas cages I can hire out there? I have Googled this but am struggling.

Thanks in advance.
