Torque Reaction Arm, Tool Support System & Assembly Arms
Why are Tool Assembly Systems Good for Business?
As an ergonomic company we focus on making life on the operator a little easier. A torque arm takes the reaction of air & electric powered screwdrivers, nut runners, tappers and hand drills and transfers it to the arm. Also, the arms support the weight of the tool, reducing the burden on the operator to constantly support a tool all day. On some of our higher end models, we have the option to provide downward force when the tool is activated. While the ergonomic benefits are obvious, the following production benefits can give you the ROI needed to justify the arms:
Production Benefits
- Keeps the driver in alignment with fastener and work piece, eliminating cross threading, broken bits, screw head burrs and out of square fasteners.
- As the tools are constantly secured, it keeps expensive tools from being dropped or misplaced.
- Cycle time is reduced as the tooling is in a consistent location in the area.
- Reduces damaged or burred driving screws with tools held on an angle and slipping off the screw head
