Enhancing ASRS Safety in warehouse automation with interlocking solutions

As warehouse automation continues to increase, automated storage and retrieval systems (ASRS or AS/RS) have become essential for optimising space and reducing labour costs, allowing a more efficient storage and retrieval of items in specific locations. These systems, which include shuttles, cranes, carousels, and vertical lifts, may span across multiple aisles and are widely utilised in manufacturing and distribution facilities.

However, the complexity and scale of ASRS introduce several challenges, particularly around meeting safety standards and preventing system downtime (which can result in reduced overall productivity and financial loss). In addition, their moving parts and automated components pose potential hazards to personnel who may need to access the aisles and therefore appropriate measures to reduce risk must be implemented.

The challenges and considerations in selecting ASRS safety solutions include:

Conformity with globally recognised standards - Identifying the right solutions to meet safety standards can be difficult across regions (e.g., EN 528 - the European standard about rail dependent storage and retrieval equipment). Fortress machinery safety expertise and configurable solutions help organisations maintain compliance wherever they operate.

User-friendly operations - Ensuring operators can work without unnecessary complexities is essential to enhance workflow efficiency. This can be achieved by integrating key-operated switches, pushbuttons, and other functionalities within the same unit.

Network integration capability - Many warehouses face challenges integrating safety devices within their existing systems. Whether using PROFINET, EtherNet/IP, or EtherCAT, network-enabled interlocks and control pods can allow for rapid installation, reduced wiring, and simple troubleshooting, minimising downtime and maximising productivity.

Scalability across ASRS environments - As warehouse operations evolve, safety solutions need to adapt to changing business needs and growth. All-in-one ASRS interlocking solutions are highly versatile and suitable for both small-scale and large-scale operations while maintaining optimal performance.

Durability in demanding settings - Industrial settings call for rugged equipment that can withstand long-term use. Fortress devices are engineered for longevity, with robust, heavy-duty designs that ensure performance over extended periods, reducing maintenance costs and enhancing long-term safety.

With over 40 years of experience in machinery safety and interlocking, Fortress Safety has become a trusted provider across all industries and applications, including logistics, warehouse automation, and ASRS.

Interlocking devices for aisle access from Fortress incorporate essential features for optimal protection and compliance, including:

- Guard locking functionality for enhanced personnel safety

- Escape release for quick exit in case personnel becomes trapped

- Integrated pushbuttons to improve user efficiency and streamline operations

- Network connectivity to enable seamless integration with multiple communication protocols

There are also several optional features that can be configured into each device, such as RFID readers to manage and control access, personnel keys to prevent unexpected start-up, and more. Products are designed with flexibility in mind and can be configured to meet the requirements of each facility.

As automation continues to redefine industries, Fortress remains committed to delivering world-class solutions for ASRS safety that prioritise personnel protection without compromising efficiency.
