Fixed Location No-Fly Zone Systems
No-fly zones refer to protected areas where normal crane operation is limited or entirely restricted.
Depending on the application, no-fly zone systems can incorporate a variety of motion control products, including variable frequency drives, radio remote controls, limit switches, and sensors to designate locations where a crane is programmed to stop. These versatile systems—ranging from simple configurations to the more complex—can be added to existing crane controls or as new installations. Implementing no-fly zones limits the risk of collisions, increases safety for equipment and personnel, and improves facility throughput.
Fixed location no-fly zone systems utilize limit switches installed on bridge/trolley motions that interface with a no-fly zone controller for system functionality. These systems are available in three configurations optimized for fixed two-sided, three-sided, or four-sided no-fly zone applications. Each fixed location no-fly zone system includes a panel-mounted, key operated two-position enable/disable switch to allow the user to bypass no-fly zone system functionality and allow normal manual crane operation if required.
