Structural design and mechanical performance verification of a mobile piler with a double-scissor fork

Abstract The traditional piler structure is column type. stacker of this needs the same height as top warehouse. At present, there no good solution for highly inconsistent special-shaped warehouses. This paper proposes a based on requirement variable double shear fork mechanism. difference mechanism drives lifting and lowering piler. Since need to arrange rails warehouse, they can be used in warehouses with different heights. Especially less than 3 m, new has broad application space prospects. Finally, according actual working force piler, mechanical model established verified by FEM. It proved that stacking machine properties.
