Sourcing sheet metal storage equipment directly from a factory eliminates markup layers, shortens delivery timelines, and gives buyers direct access to engineering support. Herochu operates as a dedicated hand crank sheet metal storage rack factory, manufacturing crank-out storage systems for metal fabricators, steel service centers, and industrial warehouses worldwide.

Factory-Direct Manufacturing Advantages

When a storage rack is purchased through a distributor, the buyer typically receives a catalog product with limited configuration options. Factory-direct purchasing from Herochu reverses this limitation. Each crank-out sheet metal rack is built to the customer’s specifications — sheet dimensions, layer count, load capacity, and drawer clear space are all configurable before production begins.

This direct relationship also means the customer communicates with the engineering team responsible for the rack’s structural design. Questions about load distribution, floor anchoring, or integration with existing crane systems get answered by the people who designed and built the equipment.

Q235B High-Strength Steel Construction

The structural integrity of any storage rack depends on the quality of its steel. Herochu builds the main frame of every crank-out rack from Q235B high-strength steel. This grade offers a yield strength of approximately 235 MPa, providing the structural rigidity needed to support 3,000 to 5,000 kg per tier without deflection.

The dual-beam design further reinforces load distribution. Rather than relying on a single support beam per tier, the dual-beam configuration spreads the load across two parallel members. This approach reduces point loading on the frame and maintains drawer track alignment even under maximum rated capacity.

Crank Mechanism Engineering

The hand crank system is the core functional element of the rack. Herochu engineers the crank drive with a gear-and-rack mechanism that converts rotational input from the handle into smooth horizontal drawer extension. The gear ratio is selected to provide mechanical advantage — a fully loaded drawer rated for 5,000 lbs requires only 20 lbs of input torque at the crank handle.

This 20% reduction in required force compared to standard pull-out drawers means the rack remains operable by a single person even at full capacity. The mechanism is designed for daily industrial use, with sealed bearings and hardened gear teeth that resist wear under repeated loading cycles.

Model Range and Production Capability

Herochu produces five standard crank-out rack models, each configurable to customer requirements:

• HC-B2513-63: 2500×1300 mm sheet capacity, 3,000 kg per level, 6 layers
• HC-B3015-63: 3000×1500 mm sheet capacity, 3,000 kg per level, 6 layers
• HC-B4015-63: 4000×1500 mm sheet capacity, 3,000 kg per level, 6 layers
• HC-B4020-65: 4000×2000 mm sheet capacity, 5,000 kg per level, 6 layers
• HC-B6020-65: 6000×2000 mm sheet capacity, 5,000 kg per level, 6 layers

All models feature mechanical assistance for material discharge and 120 mm clear space between drawers (customizable). The number of layers can be adjusted from the standard six to match ceiling height or material volume requirements.

Quality Assurance and Pre-Shipment Testing

Every Herochu crank-out rack undergoes load testing before shipment. The test procedure involves loading each drawer to its rated capacity and cycling the crank mechanism through full extension and retraction. This process verifies that the gear drive operates smoothly under load and that the drawer maintains alignment throughout its travel range.

Welds are inspected visually and dimensionally. The Q235B steel frame is measured for squareness and level before drawer tracks are installed. These steps ensure that the rack will assemble correctly on site and perform to specification from the first day of operation.

Supporting Workshop Productivity

A factory-direct crank-out rack from Herochu delivers more than storage. It creates an organized material flow that directly supports production equipment. Laser cutting machines, plasma tables, press brakes, and shears all benefit from having sheet stock positioned in an accessible, organized rack directly at the point of use.

Overhead cranes can lift sheets from extended drawers without repositioning. Vacuum lifters and magnets interface with the flat sheet surface as the drawer extends fully outward. Forklifts can access lower drawers from the floor level. This multi-mode handling compatibility means the rack adapts to whatever lifting equipment the workshop already operates.

Space Utilization and FIFO Control

The vertical stratification design converts floor footprint into storage volume. Six levels of crank-out drawers multiply storage capacity within the same floor area — up to four times the density of traditional flat stacking. Each drawer is independently labeled, enabling first-in, first-out (FIFO) inventory management that prevents rust, obsolescence, and material waste from long-term backlog.

Conclusion

Purchasing a hand crank sheet metal storage rack factory-direct from Herochu means receiving equipment built to specification, tested under load, and supported by the engineering team that designed it. The Q235B steel frame, dual-beam construction, and precision crank mechanism combine to deliver a storage system that protects sheet material, maximizes floor space, and reduces the physical effort required for daily storage and retrieval operations.
