The ZR140SF Stacker Conveyor is ZOOMRY's core model focused on large-scale heavy bulk material stockpiling in ports. Equipped with a 1400mm-wide belt, it achieves an ultra-high throughput of 2100 tonnes per hour (tph) at a belt speed of 3.15m/s. Relying on the three-in-one functions of "radial rotation + telescopic adjustment + luffing lifting", combined with a 10-20m telescopic boom and a 20m stockpiling height design, it can efficiently control the entire stockpiling process of heavy bulk materials such as iron ore and coal, significantly saving port site occupation. The equipment supports transportation via 40-foot high cube (HQ) containers, completes 85% pre-assembly before leaving the factory, and can be put into operation within 10-20 days on-site. It has obtained international certifications including CE, EAC, and KCS, making it the preferred large-scale stockpiling equipment for large port bulk cargo berths and large-scale heavy bulk material transfer centers.
As a professional large-scale stockpiling equipment and radial luffing stacker, the core competitiveness of the ZR140SF Stacker Conveyor lies in the three-fold advantages of "high throughput + space-saving + stable operation". Addressing the pain points of large-scale heavy bulk materials in ports—"daily ship unloading volume reaching 10,000-tonne level and tight site resources"—it realizes "one unit replacing multiple traditional models" through function optimization. This not only solves the problems of "insufficient throughput, large site occupation, and low stockpiling efficiency" of traditional stockpiling equipment when handling large-scale bulk materials, but also ensures operational stability through precise control, perfectly matching the large-scale application needs of port stackers.
The equipment is equipped with a radial rotation system driven by dual hydraulic motors, enabling 360° dead-angle-free stockpiling. It maintains the maximum steering angle limit of 110°, and the vibration amplitude of the machine body during rotation is controlled within 2mm, with stability 35% higher than that of ordinary large-scale stackers. In large port bulk cargo berths, when facing the iron ore stockpiling demand after unloading from Capesize ships (80,000-120,000 DWT), a single ZR140SF Stacker Conveyor can cover an operating area with a diameter of 60 meters. This reduces equipment investment by 60% compared to the traditional combined solution of "3 fixed stackers + 2 transfer machines", while avoiding the complex process of multi-equipment coordinated scheduling.
The telescopic boom is welded in sections using Q355B high-strength alloy steel, with a standard telescopic range of 10-20m. It has been adaptively optimized for the characteristic of "large space differences between different berths" in ports: in old terminal berths with limited space, retracting to 10m allows stockpiling close to the shoreline, avoiding occupation of navigation channels; in newly built large berths, extending to 20m enables continuous material spreading of "long strip-shaped high-density material piles", with an hourly stockpiling area of 120㎡, 40% higher than that of fixed stackers of the same class. At the same time, the telescopic system is equipped with a "dust-proof and torsion-resistant" cable sliding device independently developed by ZOOMRY, which adopts a double-sealed structure and high-strength guide rails. It can resist corrosion from the high salt spray and dusty environment in ports, extending the cable service life to more than 10 years and reducing the maintenance frequency and cost of large-scale equipment.
The luffing mechanism is driven synchronously by four hydraulic cylinders, with a maximum stockpiling height of 20 meters—more than twice that of traditional fixed stackers (8-10m)—which can maximize the use of vertical space in ports. Calculated based on a single 5,000㎡ stockpiling area, the stockpiling capacity of the ZR140SF Stacker Conveyor can reach 150,000 cubic meters (approximately 375,000 tonnes based on the bulk density of iron ore of 2.5t/m³), increasing the site utilization rate by 100% compared to traditional stackers. This is equivalent to saving 2,500㎡ of land occupation for the port, which can reduce annual site costs by 250,000 yuan based on the port terminal land rent of 100 yuan/㎡/year. In addition, the luffing system is equipped with a "graded material dropping" control logic. When stockpiling heavy bulk materials, the falling height can be controlled within 1.2m, reducing the wear of the belt caused by material impact and extending the belt service life by 60% compared to ordinary large-scale stackers.
The drive system can select large-scale gear motors from international first-tier brands such as SEW (Germany) and FLENDER (Germany), with output power upgraded to 66kW (main conveyor) + 25kW (chassis). The motor rotor adopts a high-silicon steel sheet lamination process, with a rated torque of 2,800N·m, which can stably support the continuous conveying demand of 2,100tph heavy bulk materials. The motor efficiency reaches over 97.5%, saving 14% more energy than ordinary large-scale motors. The hydraulic power pack adopts a customized large-scale system by ZOOMRY, with an oil tank capacity of 650L and equipped with a triple high-precision filtration device (filtration accuracy of 8μm). The hydraulic oil cleanliness is maintained at NAS Class 7, reducing the wear rate of hydraulic components by 55%, and the annual system failure rate is less than 0.2%—this can avoid ship unloaders waiting for materials due to hydraulic failures.
The equipment supports three operating modes, paired with a 12-inch high-definition HMI touchscreen (supporting multi-language switching including English, Russian, and Korean). The interface is optimized for the "multi-tasking and fast response" needs of large-scale port operations:
In view of the characteristics of "large impact of heavy bulk materials and wide impact of accidents" in large-scale port stockpiling, the ZR140SF Stacker Conveyor has been strengthened in multiple aspects: In case of power failure, the hydraulic system automatically locks within 0.005 seconds. The locking mechanism is made of 40Cr forged material, which can withstand an instantaneous impact force of 80 tonnes, preventing the telescopic boom from suddenly falling due to bearing heavy bulk materials; the steel wire rope is equipped with a dual mechanical limit + real-time tension monitoring device, and if the tension deviation exceeds 5%, it triggers locking immediately to avoid the risk of rope breakage; large-scale anti-deviation switches are installed on both sides of the belt, using a thickened cast steel shell and dual trigger contacts. When the deviation exceeds ±35mm, it automatically shuts down and cuts off the incoming material signal of the ship unloader at the same time to prevent continuous spilling of heavy bulk materials (the loss of a single spill can be controlled within 150kg).
The cleaning system adopts a combined design of "double scrapers + brushes": The head and tail are each equipped with two sets of heavy-duty polyurethane (PU) scrapers (25mm thick), with a cleaning rate of 99.5%, which can completely remove the residual heavy bulk material debris on the belt surface; wear-resistant brushes are installed on both sides of the belt to further clean fine dust and reduce belt wear. Both the scrapers and brushes adopt a "quick-release buckle" design, and individual replacement only takes 30 minutes, which is 40% shorter than the maintenance time of ordinary large-scale stackers.
To address the pain points of "difficult equipment transportation and long installation cycle" in global large-scale port projects, the ZR140SF adopts a "large-scale modular disassembly + high-proportion pre-assembly" design, which greatly reduces transportation and installation difficulties while ensuring the strength of large-scale structures, ensuring the project is put into operation quickly.
Despite being a large-scale stockpiling equipment, the ZR140SF Stacker Conveyor still decomposes its core components into 4 standard units—"large-scale chassis module, segmented telescopic boom module, hydraulic power pack module, and drive module"—through scientific modular disassembly. Among them, the large-scale chassis module adopts lightweight high-strength steel, with weight controlled within 28 tonnes; the telescopic boom module is split into 2 sections (10m each), with the weight of a single section not exceeding 15 tonnes. All unit sizes are compatible with 40-foot HQ containers (12.03m in length × 2.35m in width × 2.69m in height), without the need to apply for over-width or over-weight transportation permits. Compared to the traditional "bulk + special transportation" solution for large-scale equipment, cross-border logistics costs are reduced by 45%, and it can be transported by regular container ships, avoiding cycle delays caused by special logistics.
Before leaving the factory, 85% of the equipment's pre-assembly work is completed. Key processes such as large-scale structural welding, hydraulic pipeline connection, and electrical wiring laying are all completed in the factory, and have undergone a 150-hour full-load large-scale test (simulating the continuous conveying scenario of 2,100tph heavy bulk materials) to ensure trouble-free on-site installation. On-site, only 3 core processes need to be completed: "segmented docking of the telescopic boom, venting of the hydraulic system, and commissioning of the remote control system". ZOOMRY provides a list of special tools for large-scale equipment installation and a guidance manual; if customers require, engineers with more than 10 years of experience in large-scale port equipment can be dispatched to supervise on-site installation and conduct special operator training simultaneously. According to historical project data, a skilled team can complete installation and commissioning in as fast as 10 days, and no more than 20 days at the slowest, which is a 43% reduction compared to the industry average installation cycle of 35 days for large-scale stackers.
The equipment has obtained EU CE certification (Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU), and completed 12 special tests for the safety requirements of large-scale machinery (including structural load-bearing strength, emergency braking distance, electrical safety protection, etc.), enabling it to directly enter the European Economic Area (EEA) market; it has passed the EAC certification of the Eurasian Customs Union, meeting the environmental requirements of "low temperature, heavy snow, and heavy bulk material operations" in ports of CIS countries; it has also obtained South Korean KCS certification, adapting to the noise and dust emission limit standards for large-scale equipment in South Korean ports. In addition, the equipment fully complies with the ISO 9001 Quality Management System and ISO 14001 Environmental Management System, with full traceability throughout the production process—from the material testing of large-scale structural steel (yield strength ≥ 355MPa) to the high-pressure tightness testing of the hydraulic system (withstanding 28MPa pressure without leakage), each process has detailed quality records to ensure consistency in mass production.
The quality control of core components is aligned with international large-scale equipment standards: The idlers adopt large-scale wear-resistant models independently developed by ZOOMRY, with the roller body made of 20# seamless steel pipe (12mm wall thickness), radial runout ≤ 0.4mm (better than China's GB standard of 0.5mm), rotational resistance ≤ 2.3N (better than the GB standard of ≤ 3N), and the bearings are large-scale deep groove ball bearings (model 312) with a service life of more than 60,000 hours; the roller shaft is made of 40Cr forged parts (diameter ≥ 220mm), with a shell thickness of 18mm. After CNC four-roll rounding processing, the ovality is < 1.5mm; after welding, it undergoes dual testing of ultrasonic testing (UT) and magnetic particle testing (MT) to eliminate internal stress, ensuring no deformation when bearing heavy bulk materials for a long time. ZOOMRY's self-built quality testing center (including a large-scale structural mechanics laboratory and a hydraulic system high-pressure testing laboratory) is equipped with more than 60 professional devices. Each ZR140SF Stacker Conveyor must pass 20 strict tests before leaving the factory, such as "2100tph heavy bulk material continuous conveying test", "-35℃ low-temperature start-up test", and "96-hour salt spray environment stability test", to ensure its performance is fully compatible with the large-scale operation needs of global ports.
In the scenario of large port bulk cargo berths, the equipment is mainly used for stockpiling heavy bulk materials such as iron ore, coal, and nickel ore after ship unloading, especially suitable for berths that can accommodate Panamax (60,000-80,000 DWT) and Capesize (80,000-120,000 DWT) ships. Addressing the characteristics of such berths—"high ship unloading efficiency (2,000-2,500 tonnes per hour) and large batches of heavy bulk materials"—the 2,100tph throughput can perfectly match the operation rhythm of ship unloaders, avoiding ship unloaders waiting for materials due to slow stockpiling; the 10-20m telescopic boom length can flexibly adapt to the stockpiling needs of different areas in the stockyard, and combined with the 20m stockpiling height design, it can maximize the use of limited space behind the berth and reduce the cost of temporary bulk material transfer; at the same time, the equipment is treated with an anti-corrosion coating (80μm thick), which can resist corrosion from the high salt spray environment in ports, extending the equipment service life to more than 12 years and reducing the replacement frequency of large-scale port equipment.
In addition, in the scenario of mixed stockpiling of multiple types of heavy bulk materials in ports, the PLC fully automatic mode of the ZR140SF Stacker Conveyor can preset stockpiling paths for different materials (e.g., separate stockpiling of iron ore and coal). Through precise control of luffing lifting and radial rotation, it avoids material mixing and contamination; the remote control function can reduce the exposure time of operators in high-dust environments, complying with port occupational health and safety requirements.
