Heavy steel pipes present a unique storage challenge: they are dense, long, prone to rolling, and dangerous to handle manually. The Herochu Industrial Crank-Out Pipe Racks are engineered specifically for these demanding conditions, combining a Heavy Duty Hand Cranked Long Pipe Rack design with the structural rigidity required for steel mill and pipe yard environments. Where light-duty storage systems buckle or bind under the weight of schedule 40 or schedule 80 pipe, Herochu’s carbon steel framework and heavy-gauge crank mechanisms operate reliably year after year.

The fundamental architecture of a Hand Cranked Pipe Rack from Herochu begins with the base and uprights. The bottom floor height of 330 mm provides clearance while the base plates distribute point loads over a larger floor area – critical when storing 8 tons per layer across multiple layers. Uprights are available in one to four columns per rack section, with column spacing determined by the longest material length. For example, a facility storing 24-foot pipes might choose two uprights spaced 20 feet apart (allowing 2 feet of overhang on each end) or three uprights at 12-foot intervals for better support. Herochu’s engineering team calculates the optimal upright count based on your typical load distribution and floor flatness.

Each layer in the Crank Out Cantilever Rack operates independently or in groups, depending on the crank mechanism configuration. Standard Herochu designs use a single crank per upright that extends all arms on that upright simultaneously. However, for multi-upright racks, synchronizing mechanisms can be installed so that one crank operates arms across all uprights – ensuring that a 40-foot pipe is supported evenly along its entire length during extension and retraction. This synchronization is a signature feature of Herochu’s heavy-duty line and is rarely found in lower-cost competitors.

Load capacities deserve close examination. The phrase Heavy duty Hand-cranked Crank-Out Rack can be marketing hyperbole, but Herochu backs every rating with a load test certificate. Single-layer load capacity is specified between 3 and 8 tons, but the actual safe working load depends on arm depth, arm pitch (distance between arms along the upright), and the number of layers simultaneously loaded. Herochu uses a conservative design factor of 1.5:1 for static loads and 2:1 for dynamic loads (during cranking). This means a rack rated for 5 tons per layer can actually withstand 7.5 tons without permanent deformation and 10 tons before failure – a safety buffer that protects both inventory and personnel.

The Crank Type Pipe Rack also addresses a common operational issue: pipe corrosion. Storing steel pipes directly on concrete floors promotes rust from ground moisture and chemical residues. By elevating pipes onto Herochu’s rack arms, which can be fitted with UHMW liners or replaced with galvanized arm surfaces, pipes remain dry and ventilated. For outdoor pipe yards, Herochu offers a weather-resistant coating system with zinc primer and polyurethane topcoat, rated for 1,000 hours of salt spray resistance. This makes the Hand Cranked Tube Storage Racks suitable for covered outdoor applications or unheated warehouses.

Number of layers ranges from 4 to 12, but Herochu advises customers to consider crane hook height before selecting the maximum. If a rack has 12 layers, the top layer may be 15 feet high or more. While the crank mechanism can still extend arms at that elevation, the overhead crane must have sufficient hook height to lift pipes from the top layer and clear the extended arms. Herochu provides a complete reach diagram with every quotation, showing the crane’s required working envelope.

Color choices – standard white, blue, or custom – serve a functional purpose beyond aesthetics. White racks reflect ambient light, improving visibility in dim warehouses. Blue racks are often used to designate material ready for production, while red or yellow indicate quarantine or rework materials. Herochu can also apply reflective tape or powder coat with fluorescent pigments for low-light conditions.

The movement mode (single-side assisted or double-side assisted) determines aisle width requirements. Single-side assisted racks need an aisle on only one side of the rack, making them suitable for placement against a wall. Double-side assisted racks have aisles on both sides, effectively doubling storage capacity for the same floor footprint but requiring two access aisles. Herochu can also supply mobile versions of the Hand Cranked Pipe Racks and Storage Systems with lockable casters, allowing a single rack to be moved between workstations in a fabrication shop. These mobile units typically have lower load capacities (1–2 tons per layer) but offer unmatched flexibility.

Applications for Industrial Crank-Out Pipe Racks extend beyond pipe storage. Steel mills use them for rounds and hex bars. Aluminum extruders store long profiles directly from the press. Shipyards stage curved beams and channels for hull assembly. Metal fabrication shops organize cut-to-length flat bars and angles. In each case, the hand-cranked design proves superior to forklift-dependent systems because it works with overhead cranes – the most common material handling equipment in heavy industry.

Safety features in Herochu’s design include locking pins on both extension and retraction positions. At full extension, pins drop into place automatically, preventing the arms from retracting while a crane is positioning a load. At full retraction, pins lock the arms flush against the upright, preventing accidental extension during aisle traffic or maintenance. Additionally, each crank mechanism has a built-in slip clutch that disengages if an operator continues cranking after hitting a mechanical stop – protecting the gearbox from abuse.

Maintenance is straightforward. Herochu recommends a monthly visual inspection of the crank gearbox for oil level, a quarterly lubrication of the extension slide rails with lithium grease, and an annual torque check of all anchor bolts. The racks are designed for a 20-year service life under normal operating conditions, with replacement wear components (UHMW liners, crank handles, locking pins) available as off-the-shelf parts.

To request a custom quote for a Heavy duty pipe storage Rack from Herochu, customers need to provide: the maximum pipe diameter (affects arm stop height), the maximum bundle weight (affects arm capacity selection), the typical pipe length (affects upright spacing and number of uprights), the number of distinct pipe SKUs (affects number of layers), and the preferred movement mode (single-side or double-side assisted). Herochu typically responds with a preliminary design within three business days and a firm quote within seven business days. Lead times for custom-built Crank Out Cantilever Racks range from 4 to 8 weeks depending on shop load.

For heavy industry, there is no substitute for a purpose-built, load-tested, and field-proven storage solution. Herochu’s Industrial Crank-Out Pipe Racks deliver exactly that – a safe, efficient, and long-lasting way to organize the heavy pipes and bars that keep your facility running.
