Heavy-Duty AS/RS for Wind Turbine Gearbox Remanufacturing
Smart Warehouse Upgrade by China JSSL Company Drives Efficiency and Space Optimization
In the rapidly evolving wind power industry, gearbox systems remain one of the most critical and high-value components in wind turbines. However, challenges such as high maintenance costs, low operational efficiency, and excessive space occupation have long constrained the sustainable development of gearbox remanufacturing businesses.
To address these challenges, a leading high-end gearbox manufacturer and remanufacturing enterprise partnered with China JSSL Company to implement a heavy-duty automated storage and retrieval system (AS/RS) integrated with a digital twin platform, successfully transforming traditional workshop operations into a highly efficient, intelligent logistics system.
Industry Pain Points: Space Constraints and Inefficient Operations
Wind turbine gearbox maintenance involves large, heavy, and complex components such as gears, shafts, housings, and planetary carriers. Traditionally, these components were stored on the workshop floor, resulting in:
Extensive floor space occupation
Low storage density
Inefficient material handling
High labor dependency
Increased safety risks
As gearbox sizes and maintenance volumes continued to grow, the limitations of flat storage became increasingly evident, creating an urgent need for a scalable and intelligent warehousing solution.

Customized Heavy-Duty AS/RS Solution by China JSSL Company
Based on in-depth analysis of component characteristics and operational workflows, China JSSL Company delivered a fully customized heavy-duty AS/RS solution featuring:
1. High-Density Vertical Storage
By deploying high-rise racking systems (up to 18 meters), the solution maximizes vertical space utilization without expanding the facility footprint.
This enables significant storage capacity growth within limited workshop space.
2. Heavy-Duty Handling Capability
The system is designed to handle large and heavy components, with:
Single pallet load capacity up to 3700 kg
Dual pallet size configurations (1600×1600 mm and 2100×2100 mm)
Heavy-duty stacker cranes and rail-guided transfer carts
This ensures safe and efficient storage of oversized gearbox parts.
3. Intelligent Warehouse Management (WMS + WCS)
The integrated system includes:
WMS for inventory visibility and task management
WCS for real-time equipment control and scheduling
Seamless integration with ERP and MES systems enables real-time data exchange and synchronized operations.
