Heavy Duty Electric Drawer-Type Sheet Metal Storage Rack

Steel service centers, fabrication workshops, and heavy manufacturing facilities share a persistent storage challenge: keeping large-format sheet metal and steel plates organized, undamaged, and accessible for daily production without surrendering excessive floor area. Flat stacking on the shop floor consumes valuable square footage, exposes plate surfaces to scratches and corrosion, and pushes operators into awkward manual handling that slows throughput and elevates injury risk. The Herochu Heavy Duty Electric Drawer-Type Sheet Metal Storage Rack was engineered to eliminate these compromises—pairing motorized drawer extension with a heavy-gauge structural framework that sustains concentrated loads at full extension without measurable deflection.

Structural Engineering Built for Concentrated Loads

Every Herochu drawer-type rack begins with a Q235B high-strength steel framework. The uprights and horizontal beams are assembled into welded box-beam structures that distribute weight evenly across the rack footprint, preventing the torsional twisting and beam sag that plague lighter cantilever designs under sustained heavy loading. A dual-beam crossbar configuration ties the uprights together at each tier, creating a rigid rectangular cage that maintains dimensional stability even when a fully loaded drawer extends outward from the rack body.

The structural calculations account for dynamic loading conditions, not just static weight. When a 3,000 kg drawer rolls out on its rails, the center of gravity shifts forward, and the frame must resist the resulting overturning moment. Herochu engineers reinforce the base plates, anchor points, and column intersections to absorb these forces, ensuring the rack remains plumb and stable throughout thousands of extension cycles over its service life. Pre-shipment load testing verifies that every unit meets its rated capacity before it leaves the factory.

Motorized Drawer Extension Under Full Load

The defining feature of this storage rack is the motorized drawer system. Each storage level functions as an independent tray that rolls outward on induction-hardened guide rails fitted with sealed needle and roller bearings. The rails are engineered to handle the full rated load at 100 percent extension—meaning a drawer carrying 3,000 kg of steel plate glides out smoothly and locks securely in the extended position for safe loading and picking by overhead crane, vacuum lifter, or forklift.

Heavy-duty rollers distribute the load across the rail length rather than concentrating it at contact points, which extends bearing life and maintains extension smoothness over years of daily operation. Replaceable HDPE wear strips line the drawer surfaces, protecting sensitive materials such as stainless steel, aluminum, and pre-coated sheet from scratches during placement and removal. For applications where surface finish is critical, rubber-capped dividers can be specified to isolate individual plates within each drawer.

Surface Protection for Long-Term Service

Industrial storage equipment operates in demanding environments—proximity to cutting coolants, welding spatter, abrasive dust, and humidity fluctuations. Herochu applies zinc-coated or powder-coated finishes to all exposed frame surfaces, with optional Z600 galvanizing available for facilities in corrosive or outdoor-adjacent environments. The protective coating system prevents rust propagation at welds and joints, preserving structural integrity and extending maintenance intervals well beyond what untreated steel frames can achieve.

Technical Specifications and Model Configurations

Herochu offers five standard configurations, each customizable to specific material dimensions and site constraints:

Clear space between drawers is standardized at 120 mm and can be adjusted to accommodate thicker plate stacks or specialized handling attachments. All models use electric-assisted material discharge, eliminating the physical effort required to pull or push loaded drawers manually. The frequency-conversion drive system provides soft-start and soft-stop acceleration profiles that prevent plate slippage during extension and retraction.

Applications Across Heavy Industry

The Heavy Duty Electric Drawer-Type Sheet Metal Storage Rack serves a broad range of industrial sectors. Steel distribution centers use multi-tier configurations to segregate plates by grade, thickness, and heat number, enabling rapid retrieval when specific material certificates are required for traceability compliance. Laser cutting workshops position the rack adjacent to cutting tables, using overhead cranes or vacuum lifters to transfer plates directly from the extended drawer to the cutting bed, reducing intermediate handling steps.

Heavy equipment manufacturers store large wear plates and structural components, keeping them organized and protected between production stages. The single-side operation requirement is particularly valuable where floor space is constrained—because every level pulls out for front access, only one working aisle is needed, reducing the footprint by as much as 50 percent compared to double-side access racks.

Drive Control and Operational Precision

The electric drive system incorporates frequency-conversion speed control, a technology that manages motor acceleration and deceleration through variable frequency adjustment rather than simple on-off switching. This matters for heavy sheet metal storage because plates resting on a drawer surface have no mechanical restraint—a sudden start or abrupt stop can cause a three-ton steel plate to shift, slide, or fall from the drawer edge. The soft-start and soft-stop profiles built into the Herochu drive system ramp the drawer velocity gradually over a programmable time window, ensuring that even smooth-surfaced stainless and aluminum plates remain seated throughout the extension cycle.

Wireless remote control is standard, allowing a single operator to extend or retract any drawer from a position with clear sightlines to the drawer and the surrounding work area. This is particularly valuable in crane-integrated workflows where the operator must coordinate drawer extension with crane positioning—standing at the rack-mounted controls would require walking back and forth between the crane pendant station and the rack for every pick, adding minutes to each material transfer. With remote control, the operator manages both systems from one position, maintaining visual oversight of the entire operation.

For facilities with digital production infrastructure, the control system supports touch-screen HMI panels for status monitoring and diagnostic feedback, plus Ethernet connectivity for integration with Warehouse Management Systems. This connectivity enables real-time inventory visibility—each drawer’s contents, load status, and position can be tracked in the facility’s WMS, supporting batch traceability, automatic stock reconciliation, and ERP synchronization without manual data entry.

Why Facilities Choose Herochu

Herochu designs and manufactures industrial storage systems for the most demanding material handling environments. The drawer-type rack reflects an engineering philosophy centered on structural integrity, operator safety, and long-term reliability under daily heavy-load cycling. Customization extends beyond dimensions—layer count, drawer depth, load rating, surface treatment, and control integration are all configured to match the specific workflow of each facility.

For operations that need to store heavy sheet metal safely, access it efficiently, and maximize every square meter of workshop floor, the Herochu Heavy Duty Electric Drawer-Type Sheet Metal Storage Rack delivers a purpose-built, field-proven solution.
