Torque Reaction Systems
What Is Torque Reaction?
Torque reaction systems are designed to reduce the shock delivered to the hand and arm. While often installed to remedy a safety or ergonomic issue, torque reaction systems are also used to make processes more efficient and increase productivity.
When a fastener is completely tightened by a power fastening tool, the tool stops abruptly, and the operator often experiences a jerk and shock to the wrist. This “torque reaction” is the result of a sudden transfer of force. A large enough force can injure the operator’s wrist.
Reducing Torque Reaction Effects
Tool Design and Type. Automatic shutoffs, an improved clutch, and the addition of a second handle help reduce the shock.
Ergonomic Torque Arms. A flexible torque arm prevents the tool from twisting, thus absorbing the torque shock while allowing the operator the flexibility to move it to various positions and orientations. Linear, traveling, articulated, suspended and telescoping arms are available.
Torque Bars. A bar attached to the front part of the tool or incorporated into the workstation stabilizes the tool to prevent it from rotating or moving in a way that potentially injures the operator.
