This industrial 3D model represents a jaw crusher, a powerful stone crushing machine widely used in road, bridge, and tunnel construction. The motor-driven system operates through a belt and pulley mechanism, moving the eccentric shaft to control the movable jaw. As the jaw moves up and down, it creates a crushing force that efficiently breaks down materials. This mechanical equipment is essential for construction, mining, and aggregate processing. Designed in Inventor, SketchUp, SolidWorks, the model is available in IGES (IGS) and SLDASM file formats.
