Truss manipulator is also called gantry manipulator. It uses profiles or square steel as the main frame, inlaid with linear sliding guides and gear racks. The cross-sectional shape of the refined profiles used as the motion frame and carrier is optimized by finite element analysis, and the excellence in production ensures its strength and straightness. Various guide rails have been widely used and continuously improved in various industries for many years, making them the best in the world in terms of reliability, noise reduction, load-bearing capacity, maintenance-free and overall performance.
