The 4 Sided Roll Cage Trolley is a lightweight metal trolley designed for modern material handling and storage needs. It is more flexible and safer than traditional storage tools. It is surrounded by four sides, with shelves at the bottom. In the middle, shelves made of wire mesh or steel plates can be added to increase the number of layers to transport more goods. One side is a door, which can be made into a double door or a four-door door. The bottom is four universal wheels, which can be replaced with brake type to prevent the 4 Sided Roll Cage Trolley from moving around when it is stationary. It has higher customization and can be selected according to the usage scenario.
Compared to 2- or 3-sided designs, a 4-sided configuration provides a more secure enclosure for goods, reducing the risk of items falling off during transit. This makes it especially beneficial in environments where product safety and integrity are more critical, such as high-value retail, pharmaceutical distribution, or food processing.
By featuring four panels that lock into place, these trolleys create a cage-like structure that is inherently more stable and theft-resistant than trolleys with fewer sides. The "roll" in its name refers to the trolley's ability to be effortlessly maneuvered through tight aisles or busy loading docks, thanks to swivel casters that respond more responsively than fixed wheels. Because of these benefits, a 4-Sided Roll Cage Trolley often becomes the preferred choice when protection and mobility must be balanced.
The chassis of the 4 Sided Roll Cage Trolley is commonly found in three designs, namely A frame, Z frame and square frame, which determine the folding and stacking methods.
There is a steel pipe bent into an "A" shape at the bottom as support. It has a stronger load-bearing capacity than the Z type and is more suitable for scenes with higher load requirements. It is lighter when folded, takes up less width after folding, and can be nested together, which is more convenient for centralized movement.
It has higher folding efficiency and requires less space for storage after use. And there is no protruding piece of the A type to prevent more Roll Cage Trolleys in the same space;
It has the strongest overall rigidity and is more durable than both the A frame and the Z frame. When folding, the bottom needs to be folded and the whole thing needs to be unfolded and folded. The process is relatively complicated and the horizontal space occupies more space. It is not as convenient as the A type when moving collectively.
The top design of the 4-sided Roll Cage Trolley is divided into two categories: the top is also called the Full Security Roll Cage Trolley or the Full Enclosed Roll Cage Trolley and the topless.
An easily opened and closed wire mesh cover is added to the 4 Sided Roll Cage Trolley to prevent the materials from being blown away or bumped out during transportation. The advantage of the fully enclosed design is that even if the entire Roll Cage Trolley is tipped over, the materials will not spill out.
Compared with the Full Security Roll Cage Trolley, it is lighter and easier to load and unload goods quickly, especially when it is warehouse logistics, supermarket replenishment or workshop temporary handling, it can shuttle between shelves and aisles faster.
The 4 Sided Roll Cage Trolley provides multi-layer shelf options, which users can customize according to actual application scenarios:
More suitable for placing different types or specifications of goods in different areas than single-layer designs, improving the overall management efficiency of warehouses;
The buckles on the shelves can be easily installed and removed from the Roll Cage Trolley. Compared with the fixed layer height design, it is more flexible and can adjust the spacing according to the height of the goods, thereby reducing space waste;
One side of the shelf is a hinge structure, and the other three sides have buckles. When needed, it can be propped up to add a layer, and it can be put down when not needed, which is also very convenient.
In terms of material selection, BOHONGKE provides a variety of metal solutions. You can choose according to your actual needs. Their prices are slightly different. For specific prices, please consult our sales manager:
This is a material we often use. It has a smoother surface and slightly higher strength than hot-rolled steel. It is suitable for scenes with higher requirements for appearance and moderate load requirements; we have close cooperation with suppliers. Because the purchase volume is relatively large, we can strive for a more suitable price.
It is more rust-resistant than ordinary carbon steel and is suitable for humid environments such as Milk Dairy Transport and Laundry. However, it is not suitable for use in acidic and alkaline environments because zinc will undergo chemical reactions and lose its rust resistance.
Surface treatment not only enhances appearance but also extends the service life of a roll cage trolley. BOHONGKE employs multiple finishing methods, each boasting more specific benefits:
The thicker zinc layer resists abrasion and chemical erosion, making it more suitable for outdoor or industrial wash-down environments.
Facilities that would otherwise need to repaint periodically can reduce lifecycle costs, as hot-dip galvanization lasts longer between re-coats than painted alternatives.
The thermoset polymer finish is more resistant to impact and scratching, preserving the professional appearance of the trolley longer.
Ideal for companies that want trolleys to match branding colors or be color-coded by product line.
Electrostatic attraction helps paint particles adhere even on inward bends or recesses, resulting in a finish that's more consistent than manual brushing or spraying.
Requires less setup than powder coating and can be applied in smaller batches without specialized ovens.
Selecting the right surface treatment ensures your trolley remains more resistant to wear, corrosion, and chemical exposure than untreated alternatives. It also helps maintain a professional aesthetic that reflects positively on your brand.
The choice of wheels or casters can drastically influence maneuverability and load capacity. BOHONGKE offers several options that excel in different performance aspects:
More floor protection than hard-rubber wheels: PU provides a softer ride that is gentler on delicate surfaces, making it more suitable for polished concrete or epoxy floors.
More noise reduction: The elastic nature of PU dampens vibration and sound, producing a quieter operation than metal or nylon casters.
More resistance to chemical spills: Nylon is less prone to degradation from oils, greases, and certain solvents, making it more appropriate than PU in chemical processing plants.
More load capacity for the size: Nylon cores can typically support heavier loads than PU while maintaining a similar footprint.
More traction on uneven or wet floors: Rubber treads grip better than smooth PU or nylon on surfaces that are slippery or contain debris.
More shock absorption: Provides a smoother ride over thresholds and debris than hard plastic wheels, minimizing jostling of sensitive products.
By selecting the caster material and bearing type that best matches your operational environment, you achieve more efficient material flow and fewer maintenance interventions than if you defaulted to a generic caster choice.
BOHONGKE's procurement team secures steel coils, tubing, and accessories from vetted suppliers. Because suppliers adhere to ISO 9001 and ISO 14001 standards, BOHONGKE enjoys more consistent material quality and more environmentally responsible sourcing than many competitors.
High-precision laser cutters and CNC bending machines shape the individual components (rails, posts, panels). This ensures that each part fits more accurately than if produced with older, manual methods.
Automated welding robots create consistent, stronger weld seams than manual welding. The robotic arms can adjust in real time to maintain weld integrity, offering more uniform strength across every joint.
Post-weld, skilled technicians inspect each seam for defects, guaranteeing more rigorous quality control than relying solely on automated inspection.
Depending on customer requirements, components are either sent to hot-dip galvanizing lines, powder-coating booths, or electrostatic painting stations. Because each station is purpose-built, the finish on a BOHONGKE trolley stays more uniform and more corrosion-resistant over the long term than one treated at a multi-purpose facility lacking dedicated lines.
Trained operators install shelves, attach casters, and mount locking mechanisms. Each trolley is subjected to load testing—rolling at various speeds, turning on different surfaces, and being loaded to rated capacity. This rigorous final inspection ensures that BOHONGKE's trolleys are more reliable under real-world conditions than trolleys that bypass such thorough testing.
Once approved, trolleys are partially disassembled (when required by shipping regulations) and wrapped in protective film. BOHONGKE's logistics team coordinates with freight carriers, ensuring deliveries arrive more punctually and with fewer transit-related damages than competitors who lack an integrated supply chain.
4-Sided Roll Cage Trolleys are invaluable across a wide range of industries and scenarios where secure, mobile, and organized transport is more beneficial than static shelving or pallets alone:
More efficient than open carts for moving linens between washers, dryers, and folding stations, while reducing the chance of lost or soiled items.
More hygienic and contamination-resistant than open trolleys, especially when paired with stainless steel and passivation processes, which meet stricter dairy regulations.
More secure for floor restocking during business hours. The fully enclosed design ensures that products remain upright and visible, preventing shelf-facing errors as stock is replenished.
More space-efficient than static racks because empty cages fold or nest more tightly, freeing up more square footage for additional inventory.
More adaptable than pallets for mixed-item shipments. With custom shelf configurations, couriers can transport parcels of various sizes in a single trip, cutting transportation costs.
More ergonomic than traditional hand trucks, as the roll-cage design reduces bending and twisting, yielding fewer workplace injuries.
More versatile than standard bins when pulling parts to the shop floor, because enclosed sides prevent small components from spilling.
By using 4-Sided Roll Cage Trolleys, organizations often experience more streamlined workflows, higher throughput, and lower damage rates than they would with less enclosed or less maneuverable equipment.
