Surplus KR 640 R2800‑2 Industrial Robot Arm, Second‑hand Short‑reach High‑rigidity Manipulator for Large Assembly Automation

Extra Information:

The KR 640 R2800‑2 belongs to KUKA KR FORTEC‑2 Ultra ultra‑heavy‑payload robot platform, with a rated payload of 640 kg and a maximum reach of 2800 mm. Its compact short‑arm design delivers outstanding structural rigidity and minimal deformation under heavy‑load conditions. Built with modular double‑rocker joint architecture, its transmission system is optimized for heavy‑duty cycles, enabling stable grabbing, transfer, assembly and spot‑welding of massive workpieces while maintaining consistent path and repeatability performance. The 6‑axis articulated structure supports flexible posture adjustment for complex 3‑dimensional motion paths of large heavy components. Floor‑mounted layout with compact footprint, IP65 body protection and IP67 wrist rating suits heavy‑industry, automotive and large‑equipment manufacturing environments. Supporting standard industrial communication protocols, it can integrate seamlessly with positioners, grippers, robot tracks and external axes, ideal for new‑build or retrofitted heavy‑duty automation workstations.
