- Core Features & Advantages
- Integrated reclaiming & telescopic stacking, single machine replaces multiple equipment
Combines bucket wheel digging, intermediate conveying and telescopic stacking into one unit. It fully substitutes wheel loaders, fixed belt conveyors and separate stackers, cutting equipment investment, yard occupation and labor staffing. - Large-diameter wear-resistant bucket wheel for high continuous throughput
Equipped with 2400–4600mm heavy-duty bucket wheel fitted with 8–12 wear buckets (0.15–0.4m³ each). Stepless speed 0–8rpm ensures even feeding without blockage. Handles bulk materials of 0.8–1.8t/m³ with throughput from 500 to 2000m³/h for all stockyard scales. - Wide rotation range maximizes yard storage capacity
Reclaim boom rotates ±180°, discharge arm swings ±65°. No frequent machine relocation needed to cover large stock zones. Max stacking height reaches 7800mm to fully utilize vertical yard space. - Dual-stage wide belt for long-distance low-spillage conveying
Two-stage telescopic conveyor system: feed belt width 800–1400mm, discharge belt 1000–1600mm. Smooth material flow reduces dust and spillage during long-distance transfer. - Independent drive motors with matched power for each mechanism
Separate motors for crawler travel, bucket wheel, feed belt and discharge belt. Power output precisely matched to load for stable startup, speed regulation and heavy-duty operation. - Heavy steel crawler chassis with superior terrain adaptability
Wide steel tracks reduce ground pressure for stable travel on muddy and gravel yards. Front dozer blade levels ground synchronously during operation to keep the machine steady. - Modular split design cuts cross-border logistics cost
Segmented structure can be disassembled and packed into containers to lower sea & land freight. Standardized core transmission parts simplify spare parts supply and on-site maintenance overseas. - Full model range covers all bulk stockyards
Four standard models STDL-500/1000/1600/2000 with graded throughput, perfectly matching small sand yards, medium coal yards, large ports and thermal power storage yards. - Product Introduction
The STDL series bucket wheel stacker-reclaimer consists of four standard models: STDL-500, STDL-1000, STDL-1600 and STDL-2000. It is an integrated automatic loading/unloading equipment specially developed for open coal yards, sand & gravel yards, port bulk terminals and thermal power plant storage yards. It processes bulk materials such as coal, sand and ore with density 0.8–1.8t/m³, with rated throughput ranging from 500 to 2000m³/h, suitable for automatic stacking & reclaiming in small, medium and large open stockyards.
Adopting large-diameter bucket wheel reclaiming structure, the wheel diameter ranges from 2400 to 4600mm, fitted with 8–12 heavy-duty wear buckets of 0.15–0.4m³ single capacity. The bucket wheel runs at stepless speed 0–8rpm, and the reclaim boom rotates ±180°, enabling large-area material digging without frequent machine relocation. The machine is equipped with two-stage long-distance telescopic conveyors: feed belt width 800–1400mm, discharge telescopic belt width 1000–1600mm. The discharge arm swings ±65°, and the series maximum stacking height reaches 7800mm to maximize vertical storage capacity.
Separate drive motors are configured for crawler travel, bucket wheel, feed belt and discharge belt, with power ratings accurately matched to each model for stable power supply. Fitted with thickened steel crawler chassis, the machine travels smoothly on gravel and muddy ground, and the front dozer blade levels working surface simultaneously. It integrates full reclaiming, conveying and stacking procedures, replacing loaders, fixed belts and independent stackers to save yard space and labor cost.
The machine adopts modular split design for easy disassembly and containerized shipment, effectively cutting logistics cost for overseas projects. Standardized and interchangeable core transmission components simplify spare parts procurement and routine maintenance at mines, ports and power plants worldwide. Widely exported to global mining, port and thermal power storage sites, it acts as core high-efficiency automated equipment for bulk material stockyards.
