I deal with 7000kg - 45000kg. I say go for it.
Believe me, you must be asleep, I have just been to a reach stacker thats been stood for 4 years and 6 companies later they have just found out what is wrong with it. Its going to cost them 10k to sort because the company that had the wounderfull idea of a cheap reliable machine went bust. The parts are going to be made from scratch.
So unless you have just won the euro loto, or are holding the money that has put us all into a recesion please forget it. Repair them but don't make promises you can't keep.
