Truss Robot Linear Track for Machine Tending and Long-Stroke Handling A truss style 500-3500kg truss robot track puts the robot above the work area instead of beside it. The gantry carries one to three robots on a rigid beam that travels over machine tools, pallet positions or welding fixtures, freeing floor space and giving a 1-100m stroke linear rail in 1000mm increments. The structure is built from welded steel sections machined after stress relief, driven by AC servo
