3D gantries carry out demanding positioning tasks in three dimensions. They are used to pick up, move and set down workpieces for stacking, sorting and machining operations. When designing pick-and-place systems, the grippers and tools for the task can be fitted to the item carriages and support profiles. Thanks to the wide range of basic models, users are sure to find the perfect Linear Unit combination to optimise the speed, accuracy and load-bearing capacity of their 3D application.
