System Overview
Our company's unmanned stacker-reclaimer system is a core solution designed specifically for the intelligent upgrade of large-scale open-pit and indoor bulk material yards. Integrating high-precision positioning, 3D scanning, intelligent control, and coordinated scheduling technologies, the system enables round-the-clock automated stacking and reclaiming of bulk materials such as coal, ore, and slag. This revolutionizes traditional operations that rely on manual control, operate in harsh environments, and experience high efficiency fluctuations. It is a key component in developing "unmanned material yards" and realizing intelligent manufacturing.
Core Technologies
1. Gray Bus Precision Positioning Technology
Achieve accurate positioning of the stacker/reclaimer trolley within ±1mm of travel and precise detection of rotation angles, providing the foundation for automated travel and precise positioning.
2. Laser Scanning 3D Modeling Technology
Using a combination of fixed and airborne LiDARs, this system dynamically scans the stockpile in real time, constructing a high-precision 3D digital stockpile yard, accurately calculating stockpile volume, identifying material boundaries, and stack shape.
3. Intelligent Collaborative Control Technology
Coordinated multi-mechanism control of the travel, rotation, pitch, and cantilever conveyor belts enables complex processes such as automatic material leveling, layered stacking, and cross-section reclaiming.
4. Unmanned Intelligent Scheduling System
Receives operation plans from the upper-level management system and automatically generates optimal stacker/reclaimer paths and instructions, enabling safe avoidance and coordinated operation among multiple stackers/reclaimers.
5. Industrial-Grade Wireless Communication and Redundant Network
Utilizes 5G wireless bridges and fiber optic redundant backup to ensure real-time, stable, and uninterrupted transmission of control commands and data, adapting to the harsh stockpile environment.
What problems does the system solve?
• High manual operation risks: This system frees drivers from the high-altitude, dusty, and noisy cab environment, preventing personal safety accidents.
• Uneven operation quality: This system overcomes differences in operator skill levels and ensures standardized, stable, and accurate stacking and reclaiming operations.
• Low equipment utilization: This system enables 24/7 uninterrupted operation, significantly improving equipment utilization and site turnover.
• Disconnected information management: This system addresses the issues of manual record-keeping errors and data lags, enabling real-time, transparent management of stockpiles, withdrawals, and material distribution.
• Environmental protection and material loss pressure: This system reduces dust and spillage, minimizing equipment and material losses caused by improper operation.
Why is this system necessary?
The stacker-reclaimer is the core equipment in a bulk material yard. Its level of automation directly determines the overall plant's logistics efficiency and intelligence. This system is a key step in the transition of traditional heavy industry to "Industry 4.0":
• Rigid Safety Requirements: Achieving intrinsic safety to meet the country's increasingly stringent safety requirements.
• Core Cost Reduction and Efficiency Improvement: Reducing reliance on manual labor, improving operational efficiency and equipment utilization, and directly reducing operating costs.
• Data Integration Foundation: As the core of a digital material yard, it provides real-time, accurate logistics data to MES and ERP systems, laying the foundation for intelligent decision-making throughout the plant.
• Green and Intelligent Benchmark: Building an unmanned, low-energy, green and intelligent material yard is a key way for modern enterprises to enhance their brand image and core competitiveness.
