• Speed: Maximum rotational speeds vary by model, generally between 60 to 320 rpm.
• Ergonomics: Lightweight, ergonomic designs with anti-loosening features and ergonomic triggers to reduce operator fatigue.

Tightening Strategies and Control

• Supports multiple tightening modes: torque, angle, torque-angle, speed control, clamping torque, zero-speed hold, delayed waiting, tighten to yield, and repair modes.
• Default policy templates include one-step, two-step, and self-learning strategies.
• Configurable up to 100 Pset torque programs and 100 tightening task groups to handle multi-workpiece and multi-torque requirements.

Human-Machine Interface and Usability

• Equipped with a 7.0-inch large touch screen offering programmable and guided operation.
• Real-time tightening curve display and access to historical data enhance monitoring and quality control.
• Breakpoint resume functionality prevents data loss during interruptions.
• Graphical task management guides operators through correct procedures, improving error-proofing.

Communication and Connectivity

• Supports multiple communication protocols: Bus communication (via external bus module), TCP/IP, Modbus TCP, HTTP.
• Integration with barcode scanners, IO, and Modbus for activation of Pset, Job, and task management.
• Peripheral device connectivity includes scanners, sleeve selectors, positioning arms, screw feeders, etc.
• Hot-plug support with optional cable lengths (3m, 5m, 10m) and rapid expansion ports for external modules like special or offset heads.

Data Monitoring and Traceability

• Comprehensive real-time monitoring of torque, angle, slope, and step data during tightening operations.
• Data upload to web platforms and MES integration enables multi-station monitoring and quality assurance.
• Double judgment of tightening quality by combining sensor and current measurements.
• Failure alarms detect abnormalities such as floating, sliding, or repeated tightening with one-key activation.
• Multi-level barcode configuration binds tightening results to stations, workpieces, jobs, and Psets to minimize manual errors.
• Traceability includes tightening curves with overlay support for up to 5 historical curves and statistical analysis (CP/CPK) to meet process quality standards.

Security and Process Control

• Hierarchical assembly process authority management requiring password entry for strategy and task configuration to ensure process integrity.

Applications

• Primarily targeted at automotive assembly lines including body-in-white (four doors and two covers), powertrain, and tire assembly.

Product Variants and Mechanical Details

• Available in straight and airborne/handheld ergonomic models with anti-loosening buttons.
• Output heads feature inner spline clamping and various quick connector bits (S2, HEX sizes).
• Detailed dimensional data provided for multiple models covering length, diameter, grip size, thread sizes, and mounting dimensions to ensure compatibility and ergonomic fit.
