Frequently Asked Questions
The IRB 7720 shines at managing massive heavy castings in foundries, bulky automotive parts, big welding operations, and any ultra-heavy jobs where other robots just can't match the payload.
Even under max load, the IRB 7720 delivers spot-on precision and repeatability for consistent positioning, top-quality results, and a long working life. That's essential when dealing with pricey heavy parts where downtime hits hard.
Yes, the IRB 7720's 16 variants give you the best payload-reach combos. Higher payloads often mean a touch shorter reach. Load diagrams help you pick the perfect one for your needs.
Sure, despite its heavy-duty build, sharing modular parts with the IRB 7710, longer service intervals, energy savings, and bulletproof reliability keep the total cost of ownership lower than older heavy robot designs.
Yes, the IRB 7720 handles welding just fine, though it's tuned for heavy lifting and power. For ultra-precise welds, ABB's IRB 2600 or IRB 4600 might be better picks, while the 7720 dominates heavy fabrication welding.
The IRB 7720 offers full protection packages like Foundry Prime with IP69 rating, special paints and rust-proof treatments, cooling for hot spots, and dust-resistant setups perfect for foundry work.
