In key links such as cross-border maritime transportation and port transshipment of iron ore, shiploading equipment needs to meet four core requirements simultaneously: "high-load conveying", "multi-ship type adaptation", "low material loss", and "strong environmental adaptability". Traditional fixed shiploaders, however, are increasingly unable to keep up with the trend of higher efficiency and green development in modern iron ore transportation due to issues such as insufficient flexibility, high loss rates, and weak adaptability.
The telescopic shiploaders suitable for iron ore transportation developed by ZOOMRY have become the preferred equipment for mining and port enterprises in regions such as Australia, Africa, and Southeast Asia. Moreover, ZOOMRY has emerged as one of the three core enterprises in China's long-distance bulk material conveying equipment field. The products have obtained international certifications including ISO 9001 Quality Management System, ISO 14001 Environmental Management System, CE (Europe), EAC (Russia), and KCS (South Korea), fully complying with technical standards and usage needs in different regions around the world.
Iron ore is characterized by high density (approximately 5.1g/cm³), high abrasiveness, easy dust generation, and concentrated transportation volume. Ordinary shiploading equipment is prone to problems such as "structural deformation", "material spillage", and "low shiploading efficiency". ZOOMRY has made targeted optimization designs to equip its telescopic shiploaders with five core competitive strengths:
The main body of ZOOMRY's telescopic shiploader adopts a high-grade carbon steel frame, and key stress-bearing parts are designed with a "Lattice Frame" structure. This design reduces weight by 30% while increasing structural strength by 25%, enabling the equipment to withstand the impact load of continuous iron ore conveying for a long time. Core components such as idlers and rollers are independently developed by ZOOMRY: the radial runout of idlers is ≤0.4mm (surpassing China's GB standard of 0.5mm); rollers are made of 40Cr forged steel (with a diameter of ≥200mm) and undergo ultrasonic flaw detection and stress relief treatment, with a service life of over 50,000 hours, avoiding shutdown risks caused by component wear.
The telescopic shiploader integrates three functions: "radial rotation", "telescopic adjustment", and "luffing and lifting". The radial rotation angle can reach ±110° (far exceeding the 70° upper limit of ordinary belt conveyors); the telescopic length can be flexibly adjusted according to ship types; the luffing and lifting range covers 0-16m. It can accurately adapt to mainstream iron ore transport ship types such as Barge (100-5000DWT), Handysize (10000-35000DWT), Panamax (60000-80000DWT), and Capesize (80000-120000DWT). It is particularly suitable for port terminals with limited space, enabling terminals to improve shiploading capacity without additional expansion.
To address the issues of easy spillage and dust generation of iron ore, the equipment's conveyor belt adopts a "deepened U-shaped trough design + double-sided sealed baffles" structure (adapting to the conveying characteristics of mobile stackers), achieving a material containment rate of over 98% and reducing dust emissions to below 5mg/m³, which complies with EU environmental standards. At the same time, through "material flow optimization control" technology, the equipment adjusts the conveyor belt speed and material flow guide angle in real time, reducing stratification, breakage, and compaction of iron ore during shiploading. The material loss rate is controlled within 1.5%, a 60% reduction compared to traditional shiploading equipment, resulting in annual cost savings of millions of yuan (based on an annual transportation volume of 10 million tons).
ZOOMRY's telescopic shiploader is equipped with a fully programmable PLC control system and an HMI touchscreen, supporting switching between three modes: "fully automatic, remote control, and manual". In fully automatic mode, the shiploading process can be preset, and the system adjusts the material flow speed and equipment position in real time through sensors, increasing shiploading efficiency to 200-1800 tph (tons per hour). The remote control adopts industrial-grade wireless signals, with an operating range of up to 500m, adapting to the complex operating environment of ports. The manual mode provides double protection for emergency scenarios, avoiding ship detention losses caused by system failures.
Aiming at the high-risk scenarios of iron ore shiploading, the equipment is equipped with triple safety guarantees: the hydraulic winch self-locks within 0.01 seconds in case of power failure, preventing the telescopic arm from falling; double mechanical limits are triggered when the steel cable breaks, blocking the telescopic movement; the automatic deviation correction switch is activated when the belt deviates, avoiding material spillage and belt wear. In addition, the equipment can be optionally equipped with double-sided maintenance walkways, facilitating daily maintenance and reducing maintenance downtime, with an annual effective operation time of over 8000 hours.
ZOOMRY's telescopic shiploaders (mobile stackers) suitable for iron ore transportation are centered on the ZRSL series, covering 4 mainstream models. Parameters can be customized according to customer needs, with core technical indicators as follows:
| Model | Max Throughput (tph) | Applicable Ship Types (DWT) | Telescopic Length (m) | Max Shiploading Height (m) | Drive System Options | Protection Class | Transport Packaging |
|---|---|---|---|---|---|---|---|
| ZRSL-40 | 200-600 | Barge/Handysize | 10-20 | 8 | SEW/FLENDER Motors | IP54 | 40”HQ Containers |
| ZRSL-45 | 400-1000 | Handysize/Handymax | 15-25 | 12 | SEW/FLENDER/JIE Motors | IP54 | 40”HQ Containers |
| ZRSL-50 | 600-1400 | Handymax/Panamax | 20-30 | 14 | SEW/FLENDER/JIE Motors | IP55 | 40”HQ Containers |
| ZRSL-60 | 1000-1800 | Panamax/Capesize | 25-35 | 16 | FLENDER/JIE Motors | IP55 | 40”HQ + Bulk Cargo |
Note: tph (tons per hour) refers to hourly throughput; DWT (Deadweight Tonnage) is the maximum load capacity of the ship. All models can be customized with additional functions such as anti-corrosion coatings (for marine climates) and diesel generator sets (for off-grid scenarios).
With high flexibility and strong adaptability, ZOOMRY's telescopic shiploaders (mobile stackers) have been widely used in three core global iron ore transportation scenarios:
In major iron ore producing areas such as Australia and Brazil, mines often need to load ore directly onto ships near mining sites (to reduce short-distance transportation costs). The equipment adopts a "crawler/wheeled chassis", enabling movement in complex mine terrain without large-scale civil engineering. It can be optionally equipped with an "onboard diesel generator set" to achieve independent power supply in mine sites without grid coverage, with a shiploading efficiency of 800-1200 tph. Compared with the traditional "mine-port" transshipment mode, the transportation cost per ton of iron ore is reduced by 1.2-1.8 US dollars.
Ports in iron ore importing countries such as China and India need to handle transport ships of different tonnages simultaneously. ZOOMRY's telescopic shiploaders (mobile stackers) can complete the switch from Handysize to Panamax ship types within 1 hour by "quickly adjusting the telescopic length and rotation angle", increasing the utilization rate of terminal berths by 35%. The equipment's sealing design reduces dust pollution, helping ports pass environmental acceptance (e.g., China's GB 16297-1996 Air Pollutant Emission Standard) and avoiding shutdown risks caused by environmental issues.
Ports in regions such as Southeast Asia and Africa face a marine climate with high temperature, high humidity, and high salt spray. The equipment adopts a "marine-grade anti-corrosion coating (paint film thickness ≥120μm)", stainless steel connectors, and seals, which can resist salt spray erosion and reduce equipment failure rates by 40%. At the same time, it complies with local certification standards (such as KCS certification in Southeast Asia and EAC certification in Russia), enabling deployment without additional modifications and shortening the project implementation cycle.
ZOOMRY has always built its iron ore telescopic shiploaders (mobile stackers) in accordance with "international standards" and ensures equipment reliability through a triple quality control system:
The equipment has obtained ISO 9001 Quality Management System (ensuring production consistency), ISO 14001 Environmental Management System (reducing operational pollution), CE certification (access to the European market), EAC certification (access to Russia and Central Asia markets), and KCS certification (access to the South Korean market). It also complies with three regional technical specifications: CEMA (Conveyor Equipment Manufacturers Association of the US), AS (Australian Standards), and GB (China Standards), enabling direct deployment in over 90% of countries and regions worldwide.
ZOOMRY has established a quality inspection center including a "Chemical Laboratory, Hardness Laboratory, Idler Laboratory, and Mechanical Performance Testing Laboratory", equipped with more than 60 professional testing equipment: idlers need to pass a 50,000-hour service life test; rollers need to pass ultrasonic flaw detection (100% defect detection rate); the entire machine needs to pass a 120-hour continuous full-load operation test. All equipment must meet the dual standards of "exceeding national standards and complying with international standards" before leaving the factory.
Key components such as idlers, rollers, and hydraulic winches are independently developed and produced by ZOOMRY rather than externally procured: the noise of idlers is ≤45dB (surpassing the national standard of 55dB); the rotational resistance is ≤2N (surpassing the national standard of 3N); rollers are processed by a CNC four-roll bending machine, with an ovality of <1.5mm, ensuring stable operation of the conveyor belt and avoiding failures caused by poor component adaptability.
This iron ore mine has an annual output of 15 million tons of iron ore and needs to load ore directly from the mining site onto ships for transportation to China. ZOOMRY provided 2 sets of ZRSL-50 telescopic shiploaders (mobile stackers), adapted to Handymax ship types (35000-50000DWT) with a throughput of 1200 tph. The equipment adopts a crawler chassis and a diesel generator set, adapting to the off-grid and sloped terrain of the mine. Through the "U-shaped trough + sealed baffle" design, the material loss rate was reduced from 4.8% (of traditional equipment) to 1.2%, saving approximately 5.4 million yuan in annual loss costs (based on iron ore at 100 US dollars per ton). The equipment has operated continuously for 18 months without major failures, leading the customer to place an additional order for 3 sets.
This port is an important iron ore transshipment port in West Africa and needs to handle two ship types: Barge and Panamax. ZOOMRY provided 1 set of ZRSL-60 telescopic shiploader (mobile stacker) with a telescopic length of 35m and a maximum shiploading height of 16m, capable of completing ship type switching within 30 minutes. The equipment adopts a marine-grade anti-corrosion coating and operates stably in a high-temperature and high-salt-spray environment. The port's shiploading efficiency has increased by 28%, and port detention fees have been reduced by approximately 200,000 US dollars per month, making it the "main shiploading equipment" of the port.
Against the backdrop of intensifying global competition in iron ore transportation efficiency, ZOOMRY's telescopic shiploaders, with core advantages of "high strength, high flexibility, low loss, and full adaptation", combined with international certifications and full-life-cycle services, provide "cost reduction, efficiency improvement, green and reliable" shiploading solutions for global mining and port enterprises.
