In addition to the potentially horrific consequences associated with a wheel loss, commercial vehicle operators are at risk of suspension of their Operators Licence, as well potential litigation and reputational damage. The safety and security of wheel fasteners are, therefore, dependent on a number of variables, including: the quality of the joint to the wheel hub; number of wheel nuts involved; tightening process of each wheel nut; and their servicing. TRL research suggests that wheel fixings provide adequate clamp load when all components are in good condition and properly tightened.  However, it also found that there can be issues involving joint relaxation, torque to clamp ratio and component temperature, all of which can affect joint integrity.

Powered by Lithium-Ion 36V technology with charging and battery health indicators, the SRB HA has a torque rating of up to 4000Nm and an internal torque transducer for maximum control and reliability. Clear user feedback comes from multi-functional LEDs, displaying OK/NOK status messages based on torque and angle readings.

Atlas Copco’s ergonomically designed SRB HA is the only product of its type on the market equipped with a dual trigger, which prevents the risk of finger pinch injury. Its low-reaction tensor motor technology also ensures that operators are not exposed to the risk of HAVS (Hand Arm Vibration Syndrome).  

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.
