- 70kg rated payload designed for heavy workpiece handling and machine tending, meeting the needs of automotive parts, large castings, and other heavy-duty applications.
- 2180.5mm maximum reach covers long-distance workstation layouts, reducing production line modification costs and adapting to large machining centers, stamping lines, and palletizing lines.
- ±0.06mm repeatability ensures stable precision even under heavy loads, guaranteeing consistent process alignment.
- IP54 body protection + IP65 wrist protection for reliable operation in high-dust and oil mist workshops, lowering maintenance costs.
2. High-Performance Joint Design for Stable Heavy-Duty Operation
- AC servo drives for all joints, with J4-J5 joints supporting 294N·m high torque, offering strong impact resistance and adapting to start-stop conditions of heavy workpieces.
- Maximum joint speed up to 350°/s, enabling smooth, jitter-free movements under heavy loads for faster cycle times.
- Integrated 1-Φ12mm air pipe + 16-core signal lines reduce external cable wear and simplify on-site commissioning.
- Floor-mounted installation ensures structural stability, suitable for docking with heavy equipment.
3. Industrial-Grade Durability to Reduce Operational Costs
- 570kg high-rigidity body with excellent vibration resistance, eliminating jitter during heavy-duty operation for extended service life.
- Wide operating temperature range (0~45℃) adapts to most domestic workshop conditions without additional temperature control modifications.
- Low-noise design (≤80dB(A)) improves workshop working conditions and reduces occupational health risks.
- Multi-bus communication compatibility allows seamless integration with PLCs, CNC machines, palletizers, and other mainstream industrial devices.
