What we see on this model in the field
Heavy IRB 6600/6700/7600/8700 castings must be checked for cracks at the base and arm welds. Balancing system pressure is the first health indicator we read.
Buying or selling one?
If you're buying, demand the serial number and operating hours, then verify payload and reach against the official specs in the table above. If you're selling, we buy used ABB robots of all series — on-site appraisal, prompt settlement.
