Herochu introduces the HC-S3015-83, a single-tower sheet metal warehouse measuring 3000x1500mm, engineered for manufacturing facilities that demand precision, density, and reliability in flat sheet storage. This automated retrieval system falls under the broader category of drive-in pallet racks but elevates the concept with motorized lifting and programmable logic controls. Designed for sheet metal dimensions up to 4000×2000 mm in its standard configuration, the HC-S3015-83 handles material thicknesses commonly used in automotive, HVAC, and general fabrication industries.

Structural Composition and Material Quality

Built entirely from high-grade structural steel, the Herochu single-tower system features 8 storage layers, each capable of supporting up to 5 tons. The layer length spans from 6 meters to 12 meters, providing flexibility for different sheet sizes. The 3000x1500mm footprint refers to the tower’s base dimensions, making it suitable for workshops with moderate floor space but high vertical clearance. Every steel component undergoes powder coating, a surface treatment that delivers corrosion protection, anti-rust properties, and electrostatic discharge (ESD) protection where sensitive electronic components are stored nearby.

The screw assembly method ensures that the entire structure can be disassembled and relocated without welding or permanent modifications. This is particularly valuable for growing shops that reconfigure layouts periodically. The frame incorporates foldable elements in the guide rails and shelf supports, reducing shipping volume by approximately 30% compared to welded alternatives.

Automated Storage and Retrieval Mechanism

Unlike traditional pallet racks that require forklift access aisles, the Herochu single-tower sheet metal warehouse operates on a vertical lifting principle. A single hoist travels along the tower’s height, extracting trays or cassettes from any of the 8 layers. The retrieval sequence is managed by an onboard PLC with an optional interface to warehouse management software. Each layer’s capacity of 5 tons means that a fully loaded tower can store up to 40 tons of sheet metal, assuming uniform distribution.

The system integrates double-sheet detection sensors at the loading station. When an operator or an automated guided vehicle (AGV) places a stack of sheets onto the infeed conveyor, the sensor measures thickness using magnetic or optical methods. If two sheets are detected as stuck together, the system halts and alerts the operator, preventing double feeding into downstream laser cutters or punches. This feature is critical for high-value materials like stainless steel or aluminum.

Installation and Site Requirements

Installation follows a modular screw assembly protocol. Herochu provides detailed CAD drawings and step-by-step manuals. A team of two technicians typically completes assembly within three working days, assuming a prepared concrete floor with a flatness tolerance of ±5 mm over 3 meters. The tower requires anchoring at four points, each using chemical or mechanical anchors rated for seismic loads in the region. Power requirements are 380V/50Hz or 480V/60Hz three-phase, consuming a peak of 4.5 kW during hoist acceleration.

Safety features include light curtains at the operator access point, emergency stop pull cords along the tower height, and overload protection on the lifting motor. The powder-coated finish includes a yellow safety stripe on corner posts to enhance visibility in low-light warehouse conditions.

Operational Workflow and Throughput

A typical cycle begins when the warehouse control system receives a request for a specific sheet type. The hoist moves vertically to the target layer, engages the tray with a telescopic fork, and lowers the load to the ground-level loading station. Total cycle time ranges from 45 to 90 seconds depending on travel distance. For high-throughput environments, the system can be paired with a buffer conveyor that queues up to three trays. Real-time inventory tracking is possible via barcode or RFID tags attached to each tray.

The HC-S3015-83 model comes with CE and ISO certifications, verifying compliance with European machinery directives and international quality management standards. Maintenance intervals are set at 500 operating hours for lubrication of the linear guides and 2000 hours for motor bearing replacement. Herochu supplies a cloud-based monitoring option that pushes alerts when wear parts approach their service limits.

Application Cases and ROI Considerations

Job shops that process mild steel, galvanized sheets, and perforated metals benefit most from the single-tower design. One reported case involved a sheet metal subcontractor storing 12 different grades of 1.5mm to 6mm steel. Before installing the Herochu system, they used floor stacking, which led to sheet damage and retrieval times averaging 15 minutes per bundle. After deployment, retrieval dropped to 1.5 minutes, and material loss from edge dents decreased by 80%. The powder-coated surfaces of the storage trays also prevent rust transfer from racking to clean sheets.

For businesses operating on lean principles, the single-tower sheet metal warehouse eliminates the need for dedicated forklift drivers during material handling, freeing personnel for value-added cutting or forming tasks. The 5-ton per layer capacity supports heavy blanks used in hydraulic press feeding. Combined with the anti-rust feature, this system is particularly suitable for coastal facilities where humidity accelerates corrosion.

Conclusion

Herochu’s HC-S3015-83 single-tower sheet metal warehouse measuring 3000x1500mm offers a compact, scalable, and robust solution for automated sheet metal material storage. With 8 layers, 5-ton load capacity per layer, powder-coated steel construction, and screw assembly, it meets the demands of modern fabrication shops seeking to reduce floor space usage and improve retrieval efficiency. CE and ISO certifications further assure safety and reliability in continuous operation.
