The client required an ergonomic solution that could torque two fasteners simultaneously. The challenge was that the spacing between the fasteners varied depending on the product model, meaning a fixed-position setup wouldn’t work across their range of assemblies.
GCI engineered a twin-spindle torque reaction arm with adjustable centers, designed to adapt to different fastener separations. At the core of the design are programmable dual electric linear actuators, which adjust tool positioning automatically based on the PSET sent from the controller. Because these actuators are electric and fully programmable, they provide essentially infinite positioning flexibility, making the system adaptable across multiple part sizes without manual adjustments.
To ensure operator comfort and usability, the torque arm was load-balanced, making it easy to move the twin spindles smoothly up and down. In addition, as a standard GCI feature, the system included leveling bolts at each joint. This not only ensured the arm could be leveled to prevent unwanted swinging when the parking brake is disengaged, but also improved ergonomics by eliminating the need to push “uphill” in one direction and brace for faster “downhill” motion in the other.
