Luckily I made the rack to be topless for maneuverability as it's quite heavy when complete ,I was thinking of bolting it all together so it would be easily moved but it's ok to move when the top is removed.
Added a few cross bracing to strengthen the shelves and fitted some lower legs to stop the rack from tipping over.
I don't think the rack is too heavy as it's got to hold half a ton on the 3 shelves and it's 11 foot long., the top shelf is probably stronger than it needed to be but I already had that part to start with just had to shorten the width of the monkey bars and the top shelf was done.
