4 Shelves Milk Roll Cage Features
Compared to fixed-frame trolleys, BOHONGKE's foldable panels collapse seamlessly onto the base, creating a flatter profile that maximizes backroom storage. When nested, multiple units stack more tightly than conventional cages, cutting your warehouse footprint by nearly half. This streamlined nesting system not only frees up aisle space but also accelerates turnaround times when redeploying empty trolleys.
While most roll cages offer only two tiers, our four-shelf configuration accommodates a wider variety of milk crate sizes and volumes in a single run. Each shelf supports weight more evenly than standard platforms, ensuring that bulkier items stay balanced and secure during handling. This multi-tiered arrangement reduces the number of trips needed for full loads, boosting your daily handling capacity.
Rather than settle for basic spray coatings, BOHONGKE applies an electro-galvanized finish that penetrates every weld and mesh intersection. This process delivers more consistent zinc coverage than traditional dip methods, resisting rust in humid dairy environments and extending service life beyond industry averages. Your roll cages will maintain their finish - and their structural integrity - longer under constant cleaning and temperature fluctuations.
Our Ø100 mm plastic-track wheels roll more smoothly than standard nylon casters, reducing rolling resistance on slick or uneven floors. Two swivel casters provide agile turning, while two fixed wheels guarantee straight-line stability. Integrated brakes lock each swivel caster more securely than spring-loaded alternatives, preventing unwanted drift during loading and unloading - ideal for busy production lines and retail aisles.
Unlike loose-panel systems that require manual alignment and separate latches, BOHONGKE's hinged design swings each panel into place in one fluid motion. The quick-insert pins engage more rapidly than bolt-on fixtures, cutting setup time by up to 30%. This intuitive hinge-and-pin mechanism reduces training needs for temporary staff and minimizes downtime between shifts.
Rather than juggling multiple vendors for panels, base frames, casters, and surface treatment, BOHONGKE supplies every component under one roof. This more streamlined approach cuts out coordination hassles and ensures all parts integrate more seamlessly than piecemeal sourcing.
By bundling production, plating, and quality control services, we pass on deeper discounts than you'd find ordering components separately. Our volume-based material purchasing and in-house finishing drive unit costs lower than compartmentalized supply chains.
BOHONGKE's ISO-certified factories exercise stricter controls than non-certified competitors, delivering thicker tubing, more uniform zinc plating, and more consistent welds. You'll spend less on premature replacements and repairs.
Consolidating manufacturing steps in our own facilities shaves days off transit between subcontractors. As a result, standard orders often arrive sooner than industry-average lead times, and customized units ship faster than typical bespoke workflows.
With a single point of contact managing design, production, and after-sales, your team spends less time coordinating quotes, approvals, and inspections. That simplicity lets you focus on core operations instead of supply-chain logistics.
By choosing BOHONGKE, you enjoy streamlined sourcing, deeper cost efficiencies, higher-grade trolleys, accelerated delivery schedules, and minimal administrative overhead - delivering maximum value with minimal effort.

BOHONGKE doesn't just assemble trolleys - we build every part with precision, from raw material processing to final inspection. Unlike suppliers who outsource multiple production stages, we control nearly the entire chain in-house or through long-term certified partners. This integrated model delivers faster turnaround, tighter quality control, and stronger cost efficiency than traditional factory clusters.
Our main production facility is equipped with industry-leading CNC bending machines, automated welding robots, and jig-based assembly stations. These technologies help us achieve tighter tolerances and stronger structural integrity than factories relying on manual craftsmanship alone.
In the 4 Shelves Milk Roll Cage production line:
Frame tubes are bent with digital precision, ensuring uniformity across batches.
Mesh panels are spot-welded using robotic arms for consistent strength and neater finishes.
Base structures are assembled from pre-cut steel plates and tubing, then reinforced with support beams that carry heavier loads than unbraced models.
Foldable shelves are pre-mounted and tested in-line, allowing operators to correct potential alignment issues before final packaging.
Every product passes through a digital tracking system, so we can trace each cage to its specific welding bay and batch number - a level of transparency rare among mass producers.
BOHONGKE partners exclusively with surface treatment plants that operate under strict ISO 14001 and ISO 45001 environmental and occupational safety standards. For our 4 Shelves Milk Roll Cage, we use electro-galvanizing as the default finish - applied through a multi-stage cleaning, zinc immersion, and drying process.
Unlike general plating workshops, our electro-galvanizing partner uses:
Automated rack-transfer systems for smoother material flow.
Closed-loop water filtration, reducing emissions and ensuring clean coating baths.
Electrically controlled plating tanks, which produce a more even zinc layer across all corners, bends, and welds.
This results in a cleaner, brighter finish with superior anti-corrosion performance - especially important for dairy environments exposed to moisture and cold-chain cleaning.
Our QC lab is equipped with:
Load-bearing simulation rigs, which test the cages beyond their rated weight.
Coating thickness meters, ensuring each product meets our minimum plating standards.
Salt spray test chambers, to simulate corrosion over time.
Caster rolling tests, which check for durability under repeated push-pull cycles.
Each 4 Shelves Milk Roll Cage undergoes multiple rounds of inspection - during welding, after surface treatment, and before final packing. Compared to standard factories that do only end-point checks, our layered system prevents more defects from entering the shipping phase.
Our logistics warehouse is directly connected to the assembly floor. Finished trolleys are shrink-wrapped, palletized, and loaded by a team trained in international shipping regulations. Whether it's LCL or full container, our trolleys are packaged for less movement and better protection than loosely wrapped alternatives.
BOHONGKE is a direct manufacturer with 25 years of production experience - ensuring tighter process control and faster lead times than trading-only firms.
Standard roll cages ship within 15-30 days; customized orders typically require 25-40 days, which is more competitive than industry averages.
Ordering in larger quantities or standard dimensions usually yields lower per-unit costs compared to small-batch or highly bespoke runs.
With thicker tubing and higher-grade steel wire than basic models, BOHONGKE cages offer longer lifespan and greater load stability.
Any defects in quality or short shipments trigger our replenishment policy - replacement parts or trolleys ship immediately at no extra cost.
We export to over 80 countries across Europe, North America, Asia, and Australia - offering better global coverage than many regional competitors.
A 4 Shelves Milk Roll Cage is a foldable, wheeled storage trolley designed for dairy handling and distribution. Its four adjustable shelves and sturdy, zinc-plated mesh panels make it more versatile than standard two-shelf trolleys, offering organized transport of milk crates or dairy products across warehouses and retail outlets.
Constructed from square steel tubing frames and high-tensile cold-drawn wire mesh, these panels provide stronger containment than flat-wire designs.
Each shelf folds down independently for rapid access, delivering more operational flexibility than fixed platforms.
Square-tube base welded with cross-support steel plates and filled with wire mesh for greater load distribution.
Electro-galvanizing ensures more consistent corrosion protection than traditional hot-dip methods.
Four Ø100 mm plastic-track casters (two fixed, two swivel with brakes) offer smoother, more controlled movement than generic wheels.
Optional side handles and reinforced corner bumpers deliver safer handling and reduced damage during high-frequency operations.
Rapid deployment of multiple dairy loads
Secure containment during transit
Compact nesting when idle
Easy braking and steering on various floor types
Ideal for dairy factories, supermarkets, catering services, and cold-storage facilities that require efficient handling of crates, cartons, and bulk dairy products. Its foldable design saves more back-room space compared to fixed-frame trolleys.
BOHONGKE begins by bending square steel tubing on CNC press brakes that deliver more consistent angles than manual methods. These frames undergo automated welding that produces tighter joints and fewer defects compared to hand welding.
High-tensile cold-drawn wire is laser-cut and precisely positioned within each frame. Robotic weld heads then secure the mesh more uniformly than conventional spot welding, ensuring stronger load retention under frequent use.
After thorough surface cleaning, components enter a multi-stage electro-galvanizing line. This process deposits a more even, corrosion-resistant zinc layer than hot-dip alternatives, safeguarding against humidity and repeated washdowns.
Each of the four shelves is formed from reinforced tubular supports and welded mesh, then test-fit onto the frame using jig fixtures that guarantee tighter tolerances than generic assembly lines. Quick-release pins are inserted and checked for smooth engagement.
Ø100 mm plastic-track casters - two fixed and two swivel with integrated brakes - are bolted on with torque-controlled tools. This calibration yields steadier rolling performance and more reliable braking than hand-tightened fixtures.
Every cage undergoes load testing, dimensional verification, and corrosion resistance checks in our in-house QC center. Failure rates are lower here than at many subcontracted facilities, thanks to our ISO-certified procedures.
Simply release the base locking pins and swing each hinged panel outward. This motion is faster and more intuitive than aligning loose panels, enabling teams to deploy cages in seconds.
Place heavier milk crates on the bottom shelf to maintain a lower center of gravity - this is safer and more stable than stacking weight unevenly. Use the second and third tiers for medium-weight items, and reserve the top shelf for lighter packages.
Engage the swivel casters for tight turns in narrow aisles, then switch to fixed wheels for more predictable straight-line travel. The integrated brake system locks more securely than conventional wheel chocks, preventing unwanted drift during loading or pause breaks.
Unlock the brakes, push the cage to its destination, then remove pins to fold panels inward. This folding motion is more compact than disassembling panels, letting you reclaim floor space quickly.
Wipe down zinc-plated surfaces with a mild cleaner to preserve finish. Lubricate hinge points monthly to maintain smoother action than untreated joints. Inspect weld seams and caster mounts periodically - this proactive care averts downtime more effectively than reactive repairs.
Seek suppliers using thicker tubing and higher-tensile wire than budget vendors. Thicker materials deliver longer service life and better resistance to bending under load.
Prioritize electro-galvanized finishes over spray coatings or basic hot-dip galvanizing; the former provides more uniform protection and lasts longer under harsh cleaning cycles.
Choose a manufacturer holding ISO 9001, 14001, and 45001 certifications - these standards ensure stricter process control and environmental compliance than non-certified competitors.
A reliable supplier will offer CAD-based customization for dimensions, shelf spacing, and wheel options. Compare delivery commitments - suppliers with in-house plating typically ship faster than those relying on external partners.
Opt for a factory that guarantees replenishment for any quality defects or missing parts. A supplier with direct production oversight and dedicated service teams simplifies issue resolution more than trading companies.
By following these criteria, you'll secure a roll cage and partnership that outperforms one-size-fits-all offerings - ensuring greater durability, faster delivery, and minimal administrative effort.
