Sigma 5.1 Tool Changer -For automotive welding lines-

sigma5.1(Applied Robotics)

Applied Robotics Sigma 5.1 is a heavy duty modular tool changer with greater modularity and exceptional strength to perform the heaviest jobs in factory production. The tool changer endures a higher payload capacity of 500kg and the low profile reduces inertial forces. Eliminate existing adaptor plates for Sigma 5.1’s lower weight, increased strength, and increased efficiency.
