Vertical Remnant Rack for Steel Plates: Mobile Design with Casters and Foot Brakes from Herochu

Herochu manufacturing and just-in-time production demand that materials move to the point of use, not the other way around. In a traditional fabrication shop, remnants accumulate near the cutting machine because that is where they are generated. When a downstream operation—say, a welding cell or a small parts assembly station—needs a piece of plate, a worker must walk to the cutting area, hunt through piles, and transport the remnant back. That walking and searching time adds up. A better approach is to bring the remnants directly to the workcell. Herochu recognized this need and developed a mobile version of its vertical remnant rack for steel plates, featuring heavy-duty casters and central foot brakes. This rolling rack turns remnant storage into an active part of the production workflow rather than a static inventory holding zone.

The standard Herochu vertical remnant rack for steel plates can be ordered with a caster set rated for the fully loaded weight of the rack plus all drawers. For a 15-drawer unit with each drawer holding 1,000 kg, the total potential load is 15 metric tons—far beyond what any mobile rack would carry simultaneously. In practice, shops rarely load every drawer to maximum capacity. Herochu engineers calculate the caster rating based on your typical total load, typically using 6-inch diameter polyurethane casters with a per-caster capacity of 1,500 kg. Four casters (two swivel with brakes, two rigid) provide a total capacity of 6,000 kg, which accommodates most mixed-load scenarios. The central pivot access on the swivel casters improves maneuverability in tight aisles, allowing the rack to turn in its own length.

The foot brake system is a critical safety feature on the mobile vertical remnant rack for steel plates. Unlike hand-operated brakes that require bending down, foot brakes allow an operator to lock the rack in place while keeping hands on the load. A single foot press engages all four casters simultaneously through a linkage system. This prevents the rack from creeping when you extend a heavy drawer—a drawer extension shifts the center of gravity and could cause a rolling rack to move unexpectedly. Herochu tests the brake system to hold the rack stationary on a 5-degree incline with a full load extended. The brake pads are replaceable and made from oil-resistant rubber compound that grips industrial flooring (smooth concrete, epoxy, or diamond plate) without leaving marks.

Why would you want a mobile vertical remnant rack for steel plates? Consider a fabrication shop that runs multiple laser cutting machines. Remnants generated on machine A are stored in a rack near that machine. But machine B, on the other side of the shop, sometimes needs small remnants that match the material currently on machine A’s rack. Instead of walking back and forth or maintaining duplicate remnant inventories, an operator can roll the entire rack from machine A to machine B, pick the needed remnant, and roll it back. For job shops with limited floor space, mobile racks can be staged against a wall during off-hours and then rolled into the aisle when needed for access. Weekly cleaning crews can move racks to clean underneath—something impossible with bolted-down storage.

The mobile version retains all the features of the stationary Herochu vertical remnant rack for steel plates: fully welded upright dividers, slider trays that keep sheets within the uprights during movement, and the pull-type drawer system. However, the mobile design adds two structural reinforcements. First, the base frame includes a larger perimeter tube to resist torsional forces when rolling over uneven surfaces. Second, the caster mounting plates are welded to the frame at a slight angle to ensure all four casters contact the floor even if the concrete is not perfectly level. Herochu pre-tests each mobile rack on a floor profile simulator to verify that no caster remains unloaded. The powder coating extends over the caster plates to prevent rust in the bolt holes.

From an ergonomic perspective, the mobile vertical remnant rack improves material handling efficiency. When the rack is positioned directly next to a workbench or a saw, the operator can extend a drawer and transfer the steel plate remnant directly to the cutting surface without carrying it across the shop. The caster height—125 mm standard, 200 mm optional—raises the lowest drawer to a comfortable working height (approximately 300 mm off the ground). This reduces bending compared to stationary racks that sit flush on the floor. For high-frequency remnant retrieval (multiple times per shift), the ergonomic benefits translate directly to reduced fatigue and lower risk of back injuries.

The mobile rack also supports the concept of a “remnant cart” for rush jobs. Imagine a customer calls with an urgent order for five parts that require a specific thickness of hot-rolled steel. You check your inventory system, locate the correct remnant in a Herochu vertical rack, and roll the entire rack to the CNC plasma table. The operator pulls the drawer, extracts the remnant, cuts the parts, and returns any leftover to the same drawer. The whole process takes minutes. Without a mobile rack, you would need to unload the remnant, carry it (or forklift it) to the cutting table, and then figure out where to store the leftover piece again. The mobile rack keeps everything organized and moving.

Herochu offers customization on mobile racks as well. You can specify central steering (a tow bar attachment) if you plan to move the rack with a tugger or powered cart. The foot brakes can be upgraded to a hand-lever system with a visual lock indicator for ISO-compliant facilities. The caster material can be chosen for specific floor types: nylon for rough concrete, polyurethane for sealed floors, or steel for high-temperature environments (e.g., near heat-treat furnaces). Delivery for mobile racks follows the same 30-day cycle as stationary units, with an additional week for caster integration if non-standard sizes are required.

Installation of a mobile vertical remnant rack for steel plates is simpler than stationary because no floor anchors are needed. Herochu still offers on-site assembly to ensure the casters are aligned and the brakes function correctly. The online guidance option includes a caster adjustment procedure: shims placed under the caster plate to compensate for floor irregularities. Herochu provides a pack of stainless shims and a torque wrench specification for the caster bolts. Every six months, Herochu recommends rotating the casters (swapping rigid with swivel positions) to distribute wear and checking the brake pads for thickness. Replacement casters are available directly from Herochu’s spare parts catalog.

In conclusion, the Herochu vertical remnant rack for steel plates in its mobile configuration bridges the gap between storage and production. Heavy-duty casters and foot brakes provide safe, stable mobility. The rugged construction remains robust even when rolled daily across shop floors. By bringing remnants directly to the point of use, this rack supports workflows, reduces material handling labor, and enables rapid response to rush orders. Whether you pair it with a laser cutting cell, a press brake, or a manual saw, the mobile Herochu vertical remnant rack turns your scrap inventory into a dynamic asset that moves with your work.
