The spring assitors that are more prone to breaking the road springs are the rubber ring type that fit between the coils.
I have used the above in the past, not very good. I have also used air assisted shocks,excellent, and air assisted springs ( air ballon inside spring ) these are very good or air bags to fit on the bump stops. You can also buy secondary springs to fit inside springs that take the weight , these are very good as they dont spoil the ride height but in your case as the weight is permanent I would contact these people,

I have used this company many many times and all the products have done what they say on the tin.
