Optimized for Moscow logistics networks, industrial storage facilities, and advanced supply chain configurations.
As the largest logistics node in Eastern Europe, the Moscow Metropolitan Area (including the Central Ring Road A-113, Domodedovo, Sheremetyevo, and key suburban industrial zones like Podolsk and Dmitrov) faces unprecedented demand for highly efficient storage systems. The rapid growth of e-commerce channels (such as Wildberries and Ozon), coupled with complex pharmaceutical cold chains and food supply lines, has pushed real estate costs higher. Consequently, standard static racking systems are no longer sufficient to meet modern operational demands.
Gravity Sliding Racks—commonly referred to as Gravity Flow Racks or Roller Tracks—utilize a sloped bed of rollers (typically inclined at 3% to 4%) to automatically transport pallets or cartons from the loading face to the picking face via gravitational force. This setup functions on a strict First-In, First-Out (FIFO) flow. By eliminating internal access aisles, gravity racks reduce floor space requirements by up to 60% compared to traditional selective racking, while offering high density and rapid stock rotation.
Designing gravity flow systems for the Moscow region requires specialized engineering to handle cold and ambient environments. During winter, temperatures in unheated or semi-heated transit warehouses can drop significantly. Under these conditions, standard steel components can become brittle, and standard roller bearings can experience lubricant freezing.
Shenzhen Sunli addresses this by using structural carbon steels (such as Q235B and Q355B) characterized by high impact toughness at low temperatures, combined with custom-formulated synthetic bearing lubricants rated for operating temperatures down to -30°C. This ensures consistent pallet movement without structural degradation or lockups on the roller track.
A reliable gravity sliding rack system relies on precise engineering. The physics of moving load weights ranging from 500kg to over 1,500kg down an inclined track requires several integrated safety mechanisms:
To prevent runaway pallets, speed controllers (or centrifugal brake rollers) are integrated into the roller tracks. These units regulate pallet travel speed to a safe, constant velocity of approximately 0.1 to 0.25 meters per second, regardless of pallet weight variance.
At the extraction face, the cumulative gravity pressure of rear pallets can jam the front pallet. Sunli's heavy-duty separators isolate the lead pallet from rear line pressure, allowing forklifts to extract pallets smoothly and safely without backpressure.
Pallet entry guides assist forklift operators in centering pallets on the roller lane, preventing tracking deviations and roller damage. Robust end-stops securely halt the final pallet at the extraction face.
Every gravity lane configuration designed by Shenzhen Sunli is calculated using the following criteria:
Shenzhen Sunli Intelligent Logistics Equipment Co., Ltd. combines advanced manufacturing technology with efficient logistical routes to serve clients in Moscow and surrounding regions. Operating out of our 38,000 m² state-of-the-art facility, our processes ensure structural reliability, dimensional accuracy, and timely project delivery.
Our facility features automated rolling lines, robotic welding stations, and an integrated powder-coating system. By handling structural design, automated profiling, and multi-stage anti-corrosion coating under one roof, we maintain consistent product quality. Our 28-engineer R&D division continuously refines load-bearing configurations, developing over 120 custom solutions annually to meet changing market requirements.
Logistics and Transit to Moscow: The Sino-Russian trade corridor provides direct rail connections from major Chinese hubs (including Chengdu, Xi'an, and Shenzhen) straight to Moscow terminals like Bely Rast, Vorsino, and Silikatnaya. Shipping via block trains takes approximately 14 to 20 days. This overland route avoids maritime delays, ensuring that large-scale racking projects are delivered on schedule.
Our manufacturing and quality-assurance systems ensure that each upright frame, box beam, and roller assembly conforms to strict international standards.
Efficient supply chain operations require storage systems designed around specific industry workflows. Our gravity racking designs address key logistical needs in Moscow's primary commercial sectors:
In cold chain environments, keeping operating costs low is critical. Since cooling large spaces is expensive, high-density storage is highly advantageous. Our dynamic gravity systems store pallets up to 10–12 deep, minimizing open volumes that require refrigeration. Standard structural components are protected by anti-rust zinc-rich coatings that resist condensation damage caused by rapid temperature shifts during shipping cycles.
Large distribution centers around Moscow handle high SKU turnover daily. Our Carton Flow Systems utilize inclined roller lanes to automatically slide small parts and shipping cartons forward. This ensures picker lanes remain stocked, separating inventory replenishing from picking zones to improve personnel safety and overall throughput.
Modern fulfillment networks increasingly utilize robotics. Our production lines manufacture gravity rack components to tight dimensional tolerances, ensuring alignment with Automated Guided Vehicles (AGVs) and laser-navigated forklifts. Safe operation is supported by precision level indicators and structural stabilizers that prevent system displacement over time.
