The client is a joint-stock company specializing in the production of high-pressure plunger pumps, motor accessories, and a wide range of hydraulic products. It is also one of the world's most comprehensive manufacturers in the hydraulic component supply sector, with the broadest product portfolio. Its catalog covers 27 categories, more than 3,000 specifications, and nearly 20,000 models, with products exported to over 190 countries and regions.
As an important component of its national-level 5G smart factory project, after a rigorous evaluation and selection process, the client ultimately chose DELIECN to provide a complete intelligent warehousing and logistics solution.
I. Challenges in Traditional Warehousing
With order volumes continuing to grow at an annual rate of over 30%, the client faced increasing demands on its warehousing operations as part of its intelligent manufacturing transformation:
Insufficient space
Traditional floor storage led to scattered material placement and extremely low space utilization.
Low efficiency
A large number of SKUs and fragmented orders required frequent manual picking, resulting in low efficiency and high labor costs.
Lack of digital integration
Warehouse data could not be linked with the overall production system, making lean management impossible.
Logistics bottlenecks
Materials had to be transferred between the first-floor production area and the second-floor stocking area via elevators, affecting overall efficiency and shipping rhythm.
II. Customized Solution
Based on the warehouse's linear deep structure and the storage requirement for single pallets of up to 800kg, DELIECN designed and implemented an intelligent warehousing system with double-deep stacker cranes as the core.
System configuration: Double-deep stacker crane + conveyor system + WMS/WCS/ECS/API systems + supporting auxiliary equipment.
III. Solution Highlights
- 01 Maximized Space Utilization
By optimizing the top clearance design (reduced from 600–700mm to 200mm), significant vertical space was freed. A total of 13,120 storage locations were planned, capable of storing 3,000 different component specifications, achieving high-density storage.
- 02 Efficient Workflow
A streamlined process was established: first-floor production and incoming storage → stacker crane transfer to second-floor "goods-to-person" picking → second-floor packaging and shipping. The stacker crane achieves an inbound/outbound efficiency of 160 pallets per hour, supports dual-row operations within a single aisle, and flexibly handles mixed storage of different materials. This reduces energy consumption, minimizes manual detours, and greatly improves overall operational efficiency.
- 03 Integration of Technology and Aesthetics
In the second-floor picking area, the workstations were set at 750mm height, ergonomically designed to ensure both efficiency and operator comfort. Additionally, the warehouse equipment was customized to match the client's overall factory color scheme, creating a visually unified and brand-consistent environment.
IV. Project Outcomes
Space Efficiency
The 10-level stacker crane warehouse increased space utilization by approximately 9 times compared to traditional floor storage.
Efficiency Gains
By integrating the workflow between the first-floor production and second-floor picking areas, overall operational efficiency increased by 40%.
Labor Reduction
Picking staff was reduced from 20 to 6, lowering labor costs by 70%.
Digital Upgrade
The WMS system was seamlessly integrated with the client's digital platform, enabling full-cycle traceability and lean management of materials.
