3. Technical highlights

Heavy loads and wide coverage

70 kg high load capacity for handling large metal parts, engine components or heavy pallets.

2100 mm ultra-long arm span, covering a wide range of working areas (such as vehicle welding lines, large machine tool loading and unloading).

Dynamic performance and stability

Optimized joint reducer and drive system to maintain high speed under heavy loads (up to 2.5m /s without load).

High strength casting structure design, reduce vibration during high-speed movement, suitable for precision welding and assembly.

Harsh environment adaptability

IP67/IP69K protection grade, withstand high temperature, dust, oil and high pressure cleaning (casting workshop, food processing line).

Optional explosion-proof version (ATEX certified) for use in flammable and explosive environments (e.g. chemical, spraying workshops).

Intelligent integration

Equipped with KUKA KRC5 control system, it supports multi-robot collaboration and external axis expansion.

Compatible with KUKA.PLC mxAutomation, seamless integration with Siemens/Beckhoff PLC simplifies production line automation.
