Palletiser – Multi-Door Access
Palletisers are crucial machines in the logistics and warehousing sector and are an extremely efficient way to load boxes and goods onto pallets. Due to the nature of the robotic arm, a palletiser has the potential to cause serious harm to machine operators or maintenance personnel if they are not correctly safeguarded. Palletising cells… Continue reading Palletiser – Multi-Door Access
🚚 Click on the different areas of the logistics process to learn more about machinery safety in these areas!
Palletising cells require fast access, as boxes can fall relatively often and can cause errors or even damage goods with machines carry on without realising it. So having controls at the gate provides that fast response time when an operator sees a box fall or be misplaced. While you may want… Continue reading Automated Palletizer
