ABB SWIFTI CRB 1300-7/1.4 vs KUKA LBR iiwa 7 R800
Two collaborative arms a buyer shopping for machine tending would honestly weigh against each other, with the manufacturer-published figures in one table and a plain reading of what the differences mean on a floor. We sell across brands, so we have no reason to tilt it.
| ABB SWIFTI CRB 1300-7/1.4 | KUKA LBR iiwa 7 R800 | |
|---|---|---|
| Class | Collaborative arm | Collaborative arm |
| Payload | 7 kg (15 lb) | 7 kg (15 lb) |
| Reach | 1400 mm | 800 mm |
| Sold as collaborative | yes | yes |
| Applications listed | palletizing, machine tending, material movement | assembly and screwdriving, inspection, machine tending, sanding and finishing |
| Specs checked | 2026-08-22 | 2026-08-22 |
Every figure is a manufacturer-published claim, checked on the date shown against the maker's own material, and not one of them survives contact with your part, your rate and your floor without an applications review. Prices are deliberately absent: quotes are prepared by our team and confirmed with the manufacturer.
What the numbers mean on the floor
- Payload is effectively a tie at 7 kg and 7 kg. The gripper and the part decide it, not the arm: rated payload is measured at the wrist with no tool on it.
- The ABB SWIFTI CRB 1300-7/1.4 reaches 600 mm farther than the KUKA LBR iiwa 7 R800. That matters for pallet height, bin depth and machine door clearance more than it matters at a bench.
- Both are sold as collaborative. That describes a feature set, not a safety verdict: the risk assessment on your part, your gripper and your speed is what decides whether anyone works beside it. Collaborative does not mean fenceless.
- Both are listed for machine tending. The ABB SWIFTI CRB 1300-7/1.4 is also listed for palletizing, material movement. The KUKA LBR iiwa 7 R800 is also listed for assembly and screwdriving, inspection, sanding and finishing.
What a spec sheet cannot tell you
The gripper, the fixture and the integrator decide more of the outcome than the arm. Cycle time on your part is a test, not a datasheet figure. Service footprint, spare parts and who answers the phone at 2 AM differ by brand and by state. And the price difference between two arms in the same class is usually smaller than the difference between two integrators' quotes for the same cell. A model number is not a specification, and the gripper is the project.
From our matrix
ABB SWIFTI CRB 1300-7/1.4. Longest CRB 1300 reach carries the LOWEST payload, 7 kg; IP40 standard, IP67 optional.
KUKA LBR iiwa 7 R800. Naming holds here: 7 kg total load and 800 mm reach. Seven axes with joint torque sensing; IP54.
