1. Project Overview & Client Background
This practical case study highlights a successful warehouse storage upgrade project completed by our company (Nanjing Peter Storage Equipment) for a leading local agricultural supply and cold chain enterprise based in Kabul, Afghanistan. The client is a major regional supplier and wholesaler of staple crops, specializing in large-scale potato purchasing, fresh preservation, seasonal stock storage, and bulk distribution to local supermarkets, rural markets, food processing factories, and government food reserve programs across Afghanistan. Potatoes are one of the most essential staple foods in Afghanistan with huge annual consumption and seasonal harvesting characteristics. Every year from September to November is the local potato harvest season, requiring massive short-term warehousing and long-term fresh storage to avoid market shortages and price surges in off-seasons.
Before cooperating with us, the client adopted a traditional bulk stacking storage method and simple selective pallet racks to store fresh potatoes. The original warehouse was a 4800 square meters indoor constant-temperature warehouse with basic ventilation and moisture-proof equipment, designed specifically for root vegetable storage. However, the outdated storage mode brought multiple severe operational problems, including extremely low space utilization, serious potato spoilage, chaotic inventory management, high labor costs, and inability to cope with seasonal peak storage pressure. To solve these long-term pain points and standardize potato storage management, the client decided to fully renovate the warehouse storage system and finally chose our heavy-duty drive-in racking system as the core storage solution for bulk potato inventory.
2. Original Warehouse Problems & Storage Pain Points
Afghanistan’s local climate is dry with large temperature differences between day and night, and fresh potatoes are extremely sensitive to storage environment, requiring stable ventilation, fixed stacking height, low extrusion pressure, and batch inventory management. The client’s original storage mode could not meet professional potato preservation standards, with the following prominent problems:
First, extremely low warehouse space utilization. The previous selective pallet racking required multiple wide operation aisles for forklift access, occupying nearly 40% of the entire warehouse area. A large number of valid storage spaces were wasted, and the original warehouse could only store a maximum of 1800 pallets of potatoes. In the peak harvest season, the client had to rent multiple temporary simple warehouses outdoors, which greatly increased additional rental costs, handling costs, and transportation risks. The scattered storage sites also made unified inventory management impossible.
Second, serious potato extrusion damage and spoilage loss. The traditional manual bulk stacking method had no fixed layered support structure. Potatoes at the bottom bore huge extrusion pressure, leading to frequent bruising, cracking and rot. Moreover, manual random stacking blocked internal air circulation, causing local damp and mildew in the middle and lower layers of potato stacks. Before the renovation, the client’s annual potato spoilage and damage rate remained as high as 8%–12%, resulting in huge economic losses and greatly affecting the quality of supplied goods.
Third, disordered inventory and unable to implement batch management. Potato storage has strict batch management requirements. Potatoes harvested in different periods have different freshness and shelf life, requiring strict LIFO (Last In First Out) management for batch delivery. The original storage mode mixed all batches of potatoes together, making it impossible to distinguish production batches and storage time. It was easy to cause long-stored potatoes to be overstocked and deteriorated, while newly harvested potatoes were delivered first, forming a vicious cycle of inventory backlog.
Fourth, low operational efficiency and high safety risks. The scattered stacking and disorderly aisles led to slow forklift loading and unloading speed, requiring a large number of workers to sort and handle goods every day. The labor cost remained high all year round. In addition, irregular manual stacking was prone to collapse accidents, bringing great safety hazards to warehouse personnel and equipment.
3. Customized Solution: Heavy-Duty Drive-In Racking System
After fully investigating the client’s warehouse site size, potato storage characteristics, annual inventory volume, local climate environment and budget, our professional engineering team customized a high-density, heavy-load, ventilation-optimized drive-in racking system suitable for bulk potato storage. Different from ordinary industrial racks, this set of racking was specially optimized for the storage characteristics of fresh potatoes and the harsh local storage environment in Afghanistan.
The overall racking system adopts national standard Q235 hot-rolled steel raw materials, with full automatic robotic welding and high-strength electrostatic spray anti-corrosion treatment. It is moisture-proof, rust-proof, wear-resistant and pressure-resistant, adapting to the dry and temperature-changing storage environment in Kabul. The whole system cancels redundant operation aisles, adopts integral continuous racking lane design, allowing forklifts to directly drive into the racking interior for pallet loading and unloading, maximizing the utilization of warehouse vertical and horizontal space.
The key design parameters of the project are as follows: The total racking height is 7.2 meters, with 4 storage layers, 12 main storage lanes, and a total of 3900 standard pallet storage positions. Each pallet is designed with a rated load of 1200KG, fully meeting the weight demand of bulk packaged potatoes. The supporting guide rails are thickened and reinforced to ensure stable bearing and no deformation after long-term heavy load operation. Meanwhile, we reserved uniform ventilation gaps between the racking beams and pallet positions, which effectively accelerates air circulation inside the warehouse, avoids damp and mildew of potatoes, and greatly improves the fresh-keeping effect of bulk potatoes.
In terms of operation mode, the drive-in racking system perfectly matches the client’s potato batch storage demand, adopting standard LIFO (Last In First Out) inventory mode. Newly warehoused potatoes are stored in the innermost part of the racking lane, and goods are taken from the outermost position during delivery. This mode is completely suitable for the client’s seasonal centralized warehousing and long-term batch delivery business, realizing standardized batch management of potato inventory.
4. Project Implementation & Installation Process
The whole project was completed in strict accordance with international warehouse storage standards and Afghan local warehouse safety specifications, including site measurement, scheme design, factory production, quality inspection, international transportation, on-site installation and after-sales training. Our team completed all production and delivery work within 45 working days. After the goods arrived at Kabul port, we cooperated with local formal agents to complete customs clearance and transportation efficiently.
During the on-site installation period, our professional construction team strictly followed the warehouse layout plan to complete the overall assembly, fixed reinforcement, level calibration and safety testing of the drive-in racking. After the installation was completed, we conducted multiple heavy-load pressure tests, forklift access simulation tests and ventilation effect tests to ensure that all indexes of the racking system met the design standards. At the same time, we provided free professional operation training for the client’s warehouse management personnel and forklift drivers, including standard loading and unloading procedures, daily racking maintenance, safety operation specifications and inventory management skills, to ensure the stable and efficient operation of the new system.
5. Project Operational Effects & Core Advantages
After the official put into use of the drive-in racking system, the client’s potato warehouse storage capacity, fresh-keeping effect, operational efficiency and cost control have been comprehensively improved, solving all the previous storage pain points, and the overall warehouse management has achieved standardized upgrading.
First, the warehouse storage capacity has been greatly improved. By canceling redundant aisles and making full use of three-dimensional space, the space utilization rate of the client’s warehouse has increased by more than 75%, and the total potato storage capacity has increased from the original 1800 pallets to 3900 pallets. It fully meets the peak storage demand during the potato harvest season, completely eliminates the need for temporary external warehouse leasing, and saves the client a lot of annual rental and transportation costs.
Second, the potato spoilage rate is greatly reduced. The standardized layered storage of the drive-in racking avoids excessive extrusion of potatoes, and the reserved ventilation gaps ensure smooth air circulation in the warehouse. The potato extrusion damage rate and mildew spoilage rate have dropped from the original 8%–12% to less than 2%, which greatly reduces commodity loss and improves the client’s product qualification rate and market competitiveness.
Third, inventory management is standardized and efficient. The LIFO operation mode realizes scientific batch management of potatoes, effectively avoids inventory backlog and long-term storage deterioration, ensures that the delivered potatoes are always fresh with stable quality, and greatly improves customer satisfaction.
Fourth, operational costs are reduced and warehouse safety is improved. The centralized and orderly racking layout simplifies the forklift operation process, improves the loading and unloading efficiency by more than 60%, and greatly reduces labor investment and time cost. The overall fixed and reinforced racking structure eliminates the risk of goods stacking collapse, realizing safe and standardized warehouse operation.
