In modern sheet metal processing workshops, raw material management remains a persistent challenge. Metal plates are often disorganized, leading to frequent loading/unloading, positioning, and transportation during batch cutting or bending operations. These inefficiencies result in high labor costs, reduced production efficiency, compromised accuracy, and increased safety risks. To address these pain points, automated sheet metal storage systems have emerged as game-changing solutions. Among them, the Twin-Tower, Four-Aisle Side-Discharge AS/RS with Dual-Beam Crane stands out as a cutting-edge solution for large-scale metal plate storage and retrieval.
What is the Twin-Tower, Four-Aisle Side-Discharge AS/RS?
This advanced automated storage and retrieval system (AS/RS) is designed for high-density metal plate storage in manufacturing environments. It features:
- Twin-Tower Structure: Two independent storage towers working in tandem to maximize space efficiency.
- Four-Aisle Design: Four parallel storage lanes for optimized material flow.
- Side-Discharge Mechanism: Allows seamless material extraction from the side, reducing movement within the workshop.
- Dual-Beam Crane: A robotic arm with two beams for precise handling of heavy metal plates.
Unlike traditional storage racks, this system integrates computer-controlled automation, ensuring unmanned operation while improving accuracy and safety.
Why Choose this Automated Metal Plate Storage System?
1. Space Optimization in High-Density Workshops
Many sheet metal processing plants struggle with limited floor space. Traditional storage methods often lead to material congestion, requiring frequent manual adjustments. The Twin-Tower, Four-Aisle Side-Discharge System addresses this by:
- Maximizing Vertical Space: The multi-layer design utilizes workshop height, allowing more materials to be stored in a smaller footprint.
- Reducing Aisle Width: Four narrow aisles replace wide storage lanes, enabling tighter material placement.
- Eliminating Overhead Crane Dependency: Unlike traditional gantry systems, this AS/RS does not require external cranes, freeing up valuable workshop space.

2. Automated Material Handling for Unmanned Operations
Manual loading and unloading of metal plates are labor-intensive and prone to errors. This system eliminates these issues through:
- Computer-Controlled Retrieval: The system automatically selects and delivers plates based on production needs.
- Dual-Beam Crane Technology: The robotic arm ensures precise movement, reducing material damage and positioning errors.
- Seamless Integration with Production Lines: Connects with laser cutting machines, stamping centers, and bending machines for fully automated workflows.
3. Improved Production Efficiency and Cost Savings
Inefficient material handling slows down production cycles. This automated system enhances efficiency by:
- Reducing Workpiece Access Time: Materials are retrieved instantly, minimizing downtime.
- Standardizing Loading/Unloading Processes: eliminates manual errors and delays.
- Lowering Labor Costs: Fewer workers are needed for material management, reducing operational expenses.
- Boosting Machine Utilization: Integration with MES (Manufacturing Execution System) ensures optimal production scheduling, reducing laser cutting machine idle time.
4. Enhanced Safety and Accuracy
Manual handling of heavy metal plates poses safety risks. This system mitigates hazards through:
- Precision Positioning: The robotic arm ensures accurate material placement, reducing misalignment errors.
- Reduced Human Intervention: Fewer workers near heavy machinery means fewer accidents.
- Stable Material Handling: The side-discharge mechanism prevents material slippage during retrieval.

How the System Works: A Step-by-Step Process
1. Material Feeding
- A forklift or vehicle places metal plates on a loading positioning table.
- The system scans the plate dimensions and records them in the database.
2. Storage Phase
- The hoist lifts the plates and places them in designated slots within the twin towers.
- Each plate’s position is digitally mapped for quick retrieval.
3. Retrieval Phase
- When a production order requires a specific plate, the system activates the dual-beam crane.
- The robotic arm moves to the designated storage slot and retrieves the plate.
- The side-discharge mechanism ensures smooth material transfer to the production line.
4. Unmanned Operation Integration
- The system connects with laser cutters, CNC machines, and bending centers.
- Material flows seamlessly between storage and processing without manual intervention.
