SRB HA Smart battery nutrunner

The worlds most productive battery nutrunner.

Find out more

Quicker

The SRB HA uses industry proven Tensor motor technology to deliver the highest tightening speeds available in a continuous rotation battery tool. This reduces process times and cuts costs.

Safer

The SRB HA high torque battery tool is the only tool on the market with a fully integrated twin trigger that eliminates the most common operator injury, finger pinch points.

Smarter

Integrated torque and angle transducers secure that all tightenings are done correctly and all data is recorded, while operator feedback on the tool reduces mistakes at source.

The story of the SRB HA

Watch the story of the SRB HA high torque smart battery nutrunner. From where the idea was born, to the care and consideration that went into each decision when creating and manufacturing the tool. Understand the tool from different aspects, and how Atlas Copco are taking the smart factory to the field.

Quicker, Safer and Smarter

The SRB HA is the worlds most productive battery nutrunner, with features added to make it quicker, safer and smarter than it's competitors. The SRB HA uses industry proven tensor motor technology to deliver the highest tightening speed. The nutunner is also equipped with a dual trigger to minimize the risk of injury, the only one of it's kind on the market.

Three different versions

Digital

Set and go straight from the box

srbha digital version battery nutrunner

The digital version is our basic version where the tool is ready to go straight out of the box. Use the buttons to set the desired torque and start tightening. No possibility to save the tightening data.


Smart

Connects directly to any mobile device

srbha smart version new

Pre-program up to 10 presets and 10 batches to control your process. The target can be either torque or torque plus angle. Easily shift between the settings and once the job is done, it is simple to download the data for traceability. No additonal app, software or Wifi network is needed.


Connected

Advanced process control and live data feed

srbha connected version new

 Connect your battery tool to the Power Focus 6000 controller, which takes your productivity, quality and connectivity to entirely new levels. The PF6000 controller is easily integrated into overlying systems for live data feed and analysis.

srbha mining application

Savings of over £40,000 per year

SRB HA high torque battery nutrunner used on flange application

A highly competitive company producing pressure vessels within the oil and gas sector required a method where they could control the torque. Their current method was using a maunual torque wrench. Not only were they unable to control the torque to a high degree of accuracy, but it also took a lot of time. 


The bolting process consisted of 300 x 24" bolts, which took three operators a total of 4 hours to complete. For the disassembly process, it took two operators a further 2 hours to complete. This method also resulted in two safety incidents per year, which the company wanted to eradicate from their business.

We introduced the SRB HA battery nutrunner with its integrated torque transducer to control the torque. The high speed motor improved productivity and the dual trigger function reduced risk of injuries.


With the SRB HA solution in place, it was calculated that the company would save over £40,000 per year due to the quicker process the tool can supply.


SRB HA improves wind operations

Offshore wind energy: pre-commissioning power at lower costs - Rental blog
One of the world leading wind turbine companies needed a more efficient way to tighten the pitch bearing and shrink disc application. In total there were 390 x M36 bolts to be tightened to the target torque 2250nm-2800nm.


This application is one of the most difficult to complete maintenance on, especially with their current hydraulic wrench method. It took a long time to set the wrench up, and also the company found the solution was taking too long to complete. They were also keen to free up an operator to distribute them to complete other work on different applications.

Atlas Copco introduced the Battery Nutrunner SRB HA as a solution for the application, and compared it to the current method. With the SRB HA in practice it proved to be the much quicker method and the company calculated they could free up one operator with the SRB HA in place.


Going forward with the SRB HA as the solution, one of the world leading wind energy companies will be able to save time and money for the whole process, making it a quicker, safer and smarter place to work.

Frequently asked questions

In what format can I get the data and what is the content?

You can receive the data to laptop or directly to a mobile device, and download a CSV file. In the file you can see the following data: time and date, barcode number, tool serial number, target torque, final torque, target angle, final angle, torque unit.

Can I get live data via mobile device?

Real time live data is available with the connected version, whereby tightening data is transferred out as it takes place. However, data is captured and recorded in real time within the smart tool nut cannot be transferred until the tool is connected to a mobile device.

Do all models have an internal WiFi Server?

Only 'smart' and 'connected' models have the built in WiFi server. This enables these models to connect directly to any mobile device. 'Digital' model is stand alone, and does not have the ability to connect an external mobile device. However, digital model can be upgraded to 'smart' version by contacting your Atlas Copco representative.

Does the dual trigger come as standard?

Yes, in Atlas Copco we believe that worker safety is the most important priority so all tools come supplied with fully integrated dual trigger as standard. If there is a demand to use the tool without the dual trigger, the tool can be modified. Please contact you Atlas Copco representative.

How many cycles can be achieved with one battery charge?

Battery life is very much dependant on joint type and working temperatures. As such the range can be quite wide, but can also be optimised by the tightening strategy used to programme the tool. During testing we have found the battery life to be significantly higher than competitor brands when comparing like for like conditions. We're happy to provide live demonstrations on your applications to validate this.
