ZOOMRY
As a core raw material for the global steel industry, iron ore faces four major pain points in its bulk material conveying process—especially during cross-border maritime transportation and port transshipment: high-load equipment vulnerability, difficulty adapting to multiple ship types, high material loss from spillage, and frequent failures in complex environments. Traditional fixed shiploaders, due to insufficient flexibility and limited adaptability, struggle to meet the high-efficiency and low-loss requirements of modern iron ore bulk material conveying. The telescopic shiploaders developed by ZOOMRY to address these issues, with their customized designs and international compliance, have become the preferred equipment for global mining and port enterprises handling iron ore bulk materials. ZOOMRY has obtained ISO 9001 Quality Management System certification, ISO 14001 Environmental Management System certification, and international certifications such as CE, EAC, and KCS, ensuring its equipment can directly comply with technical standards in most regions worldwide.
Core Requirements for Iron Ore Bulk Material Conveying and Equipment Adaptation
When formulating an iron ore bulk material conveying solution, it is first necessary to clarify three core requirements, then match the functional design of telescopic shiploaders accordingly. The first is load adaptation: iron ore has a density of 5.1g/cm³, which imposes extremely high demands on the structural strength of equipment during continuous conveying to avoid component deformation or wear caused by impact loads. The second is scenario flexibility: from mine sites to port terminals, there are significant differences in ship types (from 100-ton barges to 100,000-ton bulk carriers) and terrain (steep mine slopes, flat port sites) across different scenarios, requiring the equipment to have multi-dimensional adjustment capabilities. The third is environmental protection and low consumption: iron ore is prone to dust generation and spillage, so the conveying process must control dust emissions and material loss while complying with regional environmental standards (such as EU dust limits and domestic Air Pollutant Emission Standards).
Core Design of Telescopic Shiploaders
Impact-Resistant Structural Design
The main body of the telescopic shiploader adopts a Q355B high-grade carbon steel frame, with key stress-bearing parts (such as telescopic arm joints and roller support structures) featuring a "lattice reinforcement design". This reduces self-weight by 30% while increasing structural impact resistance by 25%, enabling it to withstand the load impact of continuous iron ore conveying over the long term. Core components (idlers, rollers) are independently developed by ZOOMRY: the radial runout of idlers is controlled within 0.4mm (surpassing China’s GB standard), and rollers are made of 40Cr forged steel (with a diameter of no less than 200mm). After undergoing ultrasonic flaw detection and stress relief treatment, their service life exceeds 50,000 hours, reducing conveying interruptions caused by component wear.
Multi-Dimensional Adjustment Functions
The equipment integrates three core adjustment functions: "radial rotation + telescopic adjustment + luffing and lifting", allowing flexible adaptation to conveying scenarios. The maximum radial rotation angle reaches ±110°, far exceeding the adjustment range of ordinary belt conveyors, and can cover the ship docking needs of different berths. The telescopic length can be adjusted on demand, and combined with a 0-16m luffing and lifting range, it can adapt to mainstream iron ore transport ship types—from 100DWT barges to 120,000DWT bulk carriers—improving conveying adaptability without the need for terminal expansion. For uneven sites such as mine locations, the equipment can be optionally equipped with a crawler or wheeled chassis, enabling mobile conveying without large-scale civil engineering.
Sealing and Low-Consumption Design
To address the dust generation and spillage tendency of iron ore bulk materials, the equipment’s Conveyor Belt adopts a "deepened U-shaped trough + double-sided sealed baffles" structure, achieving a material containment rate of over 98% and controlling dust emissions below 5mg/m³ (complying with EU environmental requirements). It is also equipped with a "material flow optimization control system", which adjusts the conveyor belt speed and material flow guide angle in real time to reduce issues such as stratification, breakage, and compaction during iron ore conveying. The material loss rate is controlled within 1.5%, significantly reducing loss costs compared to traditional equipment.
Selection and Operation of Telescopic Shiploaders
Equipment Selection
ZOOMRY’s telescopic shiploaders are centered on the ZRSL series, with different models corresponding to different iron ore conveying scales. When selecting equipment, two key indicators—"throughput" and "applicable ship types"—should be prioritized. For small-to-medium mines or short-distance conveying scenarios, the ZRSL-40 model is suitable, with a maximum throughput of 200-600 tph (tons per hour) and compatibility with 100-5,000 DWT ships. For medium-scale port transshipment needs, the ZRSL-45 model is recommended, with a maximum throughput of 400-1,000 tph and compatibility with 10,000-35,000 DWT ships. The ZRSL-50 model is ideal for on-site conveying in large mines, with a maximum throughput of 600-1,400 tph and compatibility with 35,000-80,000 DWT ships. For multi-ship transshipment scenarios in large ports, the ZRSL-60 model can be selected, with a maximum throughput of 1,000-1,800 tph and compatibility with 60,000-120,000 DWT ships. All models can be customized with additional functions such as corrosion-resistant coatings (for marine climates) and diesel generator sets (for off-grid scenarios) to enhance scenario adaptability.
Operational Precautions
To ensure safe and efficient conveying, three core operational guidelines must be followed. First, mode switching: the equipment supports three modes—"fully automatic, remote control, and manual". The fully automatic mode allows presetting of conveying processes, with the system automatically adjusting material flow speed via sensors; the remote control mode is suitable for complex port environments, with an operating range of up to 500m; the manual mode is only for emergency scenarios to avoid conveying interruptions caused by system failures. Second, safety protection: before startup, check the hydraulic winch’s self-locking function (locks within 0.01 seconds in case of power failure), double mechanical limits for steel cables, and automatic belt deviation correction switches to ensure no safety hazards. Third, daily maintenance: regularly inspect the rotational resistance of idlers (must be ≤2N) and roller ovality (must be <1.5mm). The equipment can be optionally equipped with double-sided maintenance walkways to reduce maintenance downtime and ensure an annual effective operating time of over 8,000 hours.
Applicable Bulk Material Conveying Scenarios
ZOOMRY’s telescopic shiploaders can cover mainstream global iron ore bulk material conveying scenarios, with targeted adaptation strategies for different scenarios.
Mine Site Bulk Material Conveying
Mine sites require direct "mining site-to-transport ship" conveying to reduce transshipment links. For such scenarios, equipment with a crawler chassis should be selected to adapt to complex mine terrain (steep slopes, gravel) and enable movement without site leveling. It should also be equipped with an onboard diesel generator set to address the lack of grid coverage in mines and ensure continuous conveying. Sealing design is used to control dust, preventing secondary pollution from conveying in mine environments while reducing material loss.
Port Transshipment Bulk Material Conveying
Ports need to handle rapid switching between multiple ship types to improve berth utilization. The equipment’s rapid adjustment function (completing adaptation to different ship types within 1 hour) can be used to reduce waiting time for ship type switching. Marine-grade anti-corrosion coatings (with a paint film thickness of ≥120μm) and stainless steel connectors are adopted to resist the high salt spray and humidity in port environments, reducing equipment failure rates. The sealing design must meet port environmental acceptance requirements to avoid conveying disruptions due to dust issues.
Cross-Border Climate-Adapted Conveying
For high-temperature, high-salt spray regions such as Southeast Asia and Africa, the equipment’s environmental adaptability must be enhanced. The equipment’s materials and coatings must comply with local certification standards (e.g., KCS for Southeast Asia, EAC for Russia) to enable deployment without additional modifications. The heat dissipation system is optimized to ensure stable operation of motors and control systems in high-temperature environments. Moisture-proof electrical components are equipped to avoid circuit failures caused by high humidity.
