Custom Torque Reaction Arm for Atlas Copco Nut Runner: Improving Safety and Productivity in Industrial Applications
In industrial applications, torque reaction arms play a critical role in maintaining worker safety, improving productivity, and reducing workplace injuries. An end user came to us looking for an ergonomic solution for an Atlas Copco ETV-ST101-370-FS-F Nut Runner. The FlexArm engineering team created a custom torque reaction arm to fit their needs.
This custom torque reaction arm is designed to provide torque reaction up to 370 NM and counterbalance the 16 lb. nut runner using a cable balancer. The arm has a maximum reach of roughly 52 inches and 18 inches of vertical stroke, providing ample workspace for the operator to work comfortably and safely. The arm’s movements are indicated by the red arrows in figure 1, ensuring that the operator can position the tool precisely for side/frontal fastening.

The arm’s design ensures that the nut runner is held securely in a fixed vertical orientation, providing easy access for the operator to perform side/frontal fastening operations with precision and accuracy. The mount connects to the tool using the bolt pattern near the head of the tool, ensuring that the arm and the tool are securely connected, and the operator can work confidently.
The cable balancer used in the arm provides a counterbalancing force that reduces operator fatigue and strain on the arm, ensuring that the operator can work for extended periods without experiencing any discomfort. The cable balancer also helps prevent damage to the tool and the assembly line by preventing the tool from accidentally being dropped or hitting the work surface
The arm’s design ensures that the operator can work with precision and accuracy, minimizing the risk of errors and rework. With the custom torque reaction arm, the operator can work comfortably and safely, improving productivity and efficiency in the assembly line.
If you’re searching for a torque reaction arm that can enhance your operational ease and safety, please fill out the custom tool mount application, or call us at 1-800-837-2503. Our engineers would happily discuss your requirements and design a tailored solution to fit your needs.

Auto Stand-Off – This is currently defined to be surface stand-off and not to be confused with vector stand-off in 5-axis mode. The current auto stand-off is based on a changing surface and will adjust vertically based on the angle of the “A” Axis, so there is five (5) axis taken into account during the calculations, but this is not the same as the tool vector stand-off. There is the ability to do the vector stand-off change while the machine is running manually with buttons on the screen.
Z-Reader Probe – The Z-Reader is a device for mapping the location of the surface. It can be controlled manually & programmatically. The option is NOT active while cutting & is retracted out of harm’s way. It can be triggered to verify the surface at every pierce before the cutting process starts, or it could be used to drive surface mapping of the whole part before cutting starts. It begins with initialization or zeroing of the device to the surface at the beginning of a program and then accumulates or tracks the difference from that zeroing effort.
Automatic Edge Finder – The edge finder is or can be utilized manually (Jogging Method & Screen Buttons), programmatically (M & G codes), or fully automatic routine (dedicated program). This option sets offsets & program rotation to match the orientation & location on the cutting table.
AC Unit Installed on Electrical Cabinet – The unit is mounted on the cabinet’s High Power (480v) side. It is close to the location where the drives are mounted. This option keeps the cabinet temperature stable and allows heat dissipation faster. The servo drives for all axes are the most significant contributors to heat inside the electrical cabinet.
5-Axis Renishaw Calibration – The calibration unit is a Renishaw model APCA45 with a modified spherical stylus. The device has a retractable cover and air purge to clear debris & dust during the activation process. It mounts to a swing arm controlled by a pneumatic rotary, so it is out of the way during regular operation and swings into the calibration position for calibration only.
