Doga: Torque Arms
Torque reaction arms and tool positioning system
A pioneer and a leader in work station ergonomics, our wide range of torque reaction arms and tool positioning systems is an active contributor to the improvement of your operators’ comfort (elimination of MSD), of the quality of your assemblies and of your productivity.
To guarantee optimal quality and traceability, most DOGA torque reaction arms are available with a positioning system. So every screw is tightened at the right location and at the right torque!

The function of positioning
Most DOGA torque reaction arms are available with or without a positioning system. This function, called "Posi-Control" or "PC", is made possible by adding position encoders to the arms. These encoders define the tool's location in space and allow for tightening sequences to be programmed. This system guarantees optimal quality and traceability.
The absolute position encoders are sensing devices that monitor the angular and/or linear movements of the tool.
DOGA torque reaction arms are fitted with from 1 to 4 sensors depending on the model. There are 4 types of position encoders:
• Contactless linear encoders on the longitudinal stroke (BA, BA...C and SLIDER models).
• Contactless angular encoders with magnets (BA, BA...G models).
• Cable encoders that monitor the extended length of the arm. They are used to confirm the distance between the tool and the screw tightening point (DMF models).
• Gyroscopic encoders that measure the arm orientation and assembly tool positioning angle relative to the screw tightening position (DMF models).
The correct combination of these different encoders offers optimal assembly tool positioning relative to the screw tightening position.
The position encoders of the torque reaction arms, when combined with the DPC Touch V2 (sequencing and assembly process monitoring interface), create a system capable of guiding an operator through complete assembly sequences.
BA - Linear / articulated / travelling torque reaction arms
Designed to be easily installed on your work surfaces, BA arms are available in different types (linear - articulated - travelling) to better adapt to each of your tightening operations. Compact, robust and versatile thanks to numerous options, BA arms guarantee perfect torque recovery, optimized tightening perpendicularity and unparalleled comfort.
SLIDER – Suspended torque reaction arms
SLIDER is the ideal solution to cramped and congested workstations. Suspended on a fixed chassis or a rail, they free workspace. Easy to install and compact, they streamline your screwing operations and optimize operator comfort. Connected to a horizontal rail they become the most ergonomic solution on line. SLIDER ... PCs are equipped with XYZ absolute position encoders. Your operators therefore necessarily respect the programmed tightening sequences. Each screw is screwed to the right torque in the right place. Nothing wrong!
DMF – Carbon fiber telescopic arms
Carbon fiber engineered, DMF telescopic arms have an unequaled weight / robustness / compactness ratio. Easy to install on existing assembly line rails, they do not disrupt the workflow. Versatile, they allow multi-directional tightening up to 500 Nm, with extreme comfort, thanks to the fluidity of their telescopic geometry. DMF ... PCs are equipped with XYZ absolute position encoders. Your operators therefore necessarily follow programmed tightening sequences. Each screw is tightened to the right torque and in the right place. No defects!
