Atlas Copco introduces cordless smart battery nutrunners

Atlas Copco Tools and Industrial Assembly Solutions launched a new range of cordless smart battery nutrunners. Delivering safer, faster, more cost-efficient and traceable high torque bolt tightening for critical applications in the energy sector are the key objectives of these nutrunners.

Previously expensive and time-consuming installation and maintenance processes carried out using hydraulic wrench methods, on wind turbines for example, have been made much faster and more cost-effective, as a result of Atlas Copco’s proven tensor motor technology, which delivers the world’s most productive output.

Enhancing safety and comfort further, the ergonomically optimised SRB HA smart battery nutrunner is the only product of its type on the market equipped with a dual trigger, designed to minimise the risk of finger pinch injury, according to the company. The single operator tool has a torque rating of up to 4,000 Nm and an internal torque transducer for maximum control and reliability. Clear 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’s 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. This enables torque, angle and batch data collection without the need for additional software. 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.

Commenting on the launch of its new smart nutrunner range, powered by Lithium-Ion 36V battery technology with charging and health indicators, Chandrashekhar Pathak Business Head India from the General Industry Segment of Atlas Copco Tools, and Industrial Assembly Solutions, said, “Presently most of the high torque battery tools available in the market are current controlled tools. The accuracy of such current controlled tools is questionable since they deliver torque output which is far away from the desired target torque. In several industries, such current controlled tools are not allowed for final tightening as they are not considered reliable enough.

The SRB HA tool from Atlas Copco is something completely different with a strain gauge transducer and an inbuilt, HMI with a digital display to show the real torque. The users are extremely happy with its simplicity in programming and its data collection capabilities. The tool delivers significant value to our esteemed customers owing to its super fast tightening speed, low noise, enhanced battery capacity and high overheat limits.”
