Plug-in Electric Torque Wrench

The plug-in electric torque wrench provides a versatile, electrically powered torque solution for bolt tightening and loosening where hydraulic infrastructure is not available or practical. Operating from a standard power supply with an integral voltage stabilization unit that corrects for input voltage fluctuations, the wrench delivers consistent torque output regardless of grid quality variation, maintaining ±5% torque accuracy throughout the operating range.

A multi-gear adjustment mode with intuitive controls allows operators to select appropriate torque levels for different bolt grades and sizes, with the ability to recommend reference tightening and loosening torque values based on bolt strength class and dimensions, while also allowing those reference values to be modified to match actual application requirements. Third-party intelligent torque calibration via software gain adjustment supports the tool's long-term accuracy and extends its effective working life by compensating for wear over time.

Optional Bluetooth or Wi-Fi module integration connects the wrench to a torque gateway system for IoT-based monitoring, data upload to supervisory systems, and MES manufacturing execution system integration, enabling complete digital documentation of fastening operations. The wrench features a reverse de-torque function for loosening operations, an exceptional power-to-weight ratio, and coverage of a wider torque range than comparable hydraulic tools in a more compact and lighter package. Suitable for precision assembly, quality-controlled maintenance, and digitally managed fastening operations in manufacturing and infrastructure environments.
