What is KR001 Direct-Push Torque Reaction Arm？
The KR001 direct-push torque reaction arm is equipped with a spring balancer that effectively absorbs the weight of both the tool and the arm itself. This significantly reduces operator workload and fatigue. During operation, all reaction forces are absorbed and counteracted by the arm, resulting in improved operating comfort and stability.

What types of tightening applications is the KR001 suitable for?
The KR001 is designed for general industrial tightening applications where sufficient workspace is available. Its adjustable working range makes it suitable for assembly lines, workstations, and maintenance areas that require stable torque absorption and controlled tool movement.
What is the difference between the indexed and non-indexed versions?
The indexed version allows the arm to lock at predefined positions, ensuring consistent tool alignment and repeatable fastening processes. The non-indexed version offers greater freedom of movement, making it ideal for applications that require frequent angle changes or flexible operation.
How does the KR001 improve operator ergonomics and safety?
The KR001 absorbs reaction torque and supports the weight of the tightening tool, significantly reducing the physical load on the operator’s arms and shoulders. This ergonomic support helps minimize fatigue, lowers the risk of repetitive strain injuries, and improves overall workplace safety.
What factors should be considered when selecting the KR001 for a workstation?
Key considerations include available workspace, required torque capacity, tool weight, and whether precise positioning is needed. Ensuring proper installation and configuration allows the KR001 to deliver optimal performance, durability, and long-term productivity benefits.
