FANUC R-2000iC/220U vs ABB IRB 6740: Heavy Robot Comparison
Updated: 12 hours ago
IN A NUTSHELL
🔎 THE KEY DIFFERENCE This comparison includes family-level ranges: FANUC R-2000iC/220U lists 220 kg and 2518 mm, while ABB IRB 6740 lists 220–310 kg and 2800–3200 mm. Select an exact variant; maximum payload and maximum reach from different versions cannot be combined. |
→ CONSIDER FANUC R-2000iC/220U Consider it when its named configuration already meets the actual load and workspace requirements. This article compares 220 kg with a published reach of 2518 mm; include the gripper and part in the load. |
→ CONSIDER ABB IRB 6740 Consider it when an exact variant in this family meets the complete tool load and required workspace. This article compares 220–310 kg with a published reach of 2800–3200 mm; include the gripper and part in the load. |
💡 THE TAKEAWAY Choose exact order codes before comparing capacity or price. Confirm the selected variant’s payload and reach together, then validate the real tool, movement path and controls against the same acceptance test. |
The FANUC R-2000iC/220U and the ABB IRB 6740 both carry 220 kg or more, but they install differently. The R-2000iC/220U mounts upside-down, working down into a cell from above. The IRB 6740 is a floor robot with 220 to 310 kg and up to 3200 mm reach, listed about 16% lower.
Quick verdict. The ABB IRB 6740 is the better value for floor-mounted heavy work, with up to 310 kg, up to 3200 mm reach and a listed price $18,000 lower. The FANUC R-2000iC/220U is the better choice when floor space is tight and the robot must work from overhead.

Price comparison

FANUC R-2000iC/220U: listed from $110,000
ABB IRB 6740: listed from $92,000
Difference: $18,000
The IRB 6740 costs roughly 16% less
Mounting and layout

The R-2000iC/220U is built to hang upside-down from a gantry or frame, which frees the floor for conveyors, fixtures and operators and lets it work down into dense automotive cells. The IRB 6740 mounts on the floor, which is simpler to install but uses floor area around the base.
Payload and reach
The IRB 6740 carries 240 to 310 kg with 2800 to 3200 mm reach, more than the 220 kg over 2518 mm of the R-2000iC/220U. From overhead, though, the FANUC's shorter reach covers a cell differently than a floor robot of the same size would.
Precision and applications

FANUC publishes ±0.05 mm for the R-2000iC/220U; ABB publishes ±0.04 to ±0.06 mm by version. FANUC lists handling, assembly, sealing, spot welding, press-to-press handling and deburring. ABB builds the IRB 6740 for handling, assembly, spot welding and machine tending.
