Payload capacityGantry robots are most notable for their payload capacity. Often resembling industrial cranes, these machines have massive metal structures that give them great mechanical strength. This construction enables them to withstand huge payloads from things like large rolls of metal and airplane components. There aren’t many applications that are too big for a gantry robot. However, plenty of applications can be too small for a gantry to make sense. For example, for small assembly tasks, such as PCB assembly, a gantry can perform the task, but would be overkill. In this instance, you would be spending a lot of money for capabilities you wouldn’t be leveraging with your gantry robot.
