The SRB HA smart battery nutrunner from Atlas Copco Tools
A new range of cordless smart battery nutrunners promises safer, faster, cost-efficient and traceable high torque bolt tightening for critical applications in the energy sector.
Installation and maintenance processes on wind turbines and other equipment is routinely carried out using hydraulic wrench methods which are seen as expensive and time-consuming. New tensor motor technology from Atlas Copco, however, has led to the development of a solution which is said to be faster and more cost-effective.
The new range of cordless nutrunners powered by lithium-ion 36 V battery technology, was launched by Atlas Copco Tools and Industrial Assembly Solutions as the only product of its type equipped with a dual trigger, designed to minimise the risk of finger pinch injury.
The single operator ergonomically designed SRB HA smart battery nutrunner has a torque rating of up to 4 000 Nm and an internal torque transducer for maximum control and reliability. Operator feedback is provided with multi-functional LEDs, displaying OK/NOK status messages based on torque and angle readings.
With three models available, the entry level SRB HA Digital version has a ‘Set and Go’ function, so it is ready for use straight out of the box. The Smart and Connected models feature an internal WiFi server, allowing the tools to be linked to any mobile device and enabling torque, angle and batch data collection without the need for additional software. For further functionality and process control, the SRB HA features an accessory bus for a barcode scanner and can also be integrated into overlying systems for live data feed and analysis.
