Frequently Asked Questions
The IRB 7720 is ideal for handling large, heavy cast parts in foundries, massive material handling for heavy automotive components, large-scale welding operations, and other ultra-heavy manufacturing tasks where no other robot can deliver the required payload.
The IRB 7720 maintains precision and repeatability even at maximum load, ensuring consistent part positioning, high-quality operations, and long service life. This reliability is critical when handling expensive, heavy components where failure is costly.
Yes, the IRB 7720's 16 variants represent the optimal combinations of payload and reach. Higher payloads typically have slightly shorter reach. Load diagrams ensure users select variants appropriate for their specific requirements.
Despite the heavy-duty nature, the modular design sharing components with IRB 7710, extended service intervals, energy savings, and reliability result in lower total cost of ownership compared to older heavy robot designs.
Yes, the IRB 7720 can perform welding operations, though it's optimized for heavy material handling and power. For precision-critical welding, ABB's IRB 2600 or IRB 4600 may be better choices, while the IRB 7720 excels in heavy fabrication welding.
The IRB 7720 supports comprehensive protection packages including Foundry Prime with IP69 protection, special paint and rust-resistant treatments, thermal management for hot environments, and dust-resistant designs for foundry operations.
