The PSA 3/1 is an overload protection and weighing system that can be used in many applications including EOT cranes, bridge cranes, container cranes, steel mill cranes, straddle cranes and harbour cranes.

The PSA 3/1 controls equipment by activating/deactivating functions via relay switches, analogue outputs or standard PSA 3/1 interfaces. The system’s flexible design incorporates all Hirschmann/PAT standard sensors and offers a wide range of operator interfaces including large numeric displays and operator consoles to meet specific application requirements.

The PSA 3/1 can be programmed to monitor all critical load conditions such as overload, unbalanced loads, slack cables, snagload and load moment. All system set up and programming is done through the user-friendly, PC based configuration manager, which does not require prior programming knowledge or special tools to operate.
