ZRSL-45 mobile shiploader

ZOOMRY’s ZRSL-45 Mobile Ship Loader takes "Cost Reduction via Automation, High Adaptability for Stable Loading, Rapid Deployment for Commissioning" as its core design concepts. It is specifically built for Handysize Max vessels (35,000-50,000 DWT) and scenarios involving heavy bulk materials such as ores. Leveraging ZOOMRY’s over 20 years of R&D experience in bulk material conveying equipment (having provided supporting solutions like belt conveyors and telescopic stackers for nearly 200 overseas projects), this equipment has obtained international certifications including EAC, CE, and KCS. It offers exceptional cost-effectiveness in terms of structural strength, automated control, and on-site adaptability, making it the preferred equipment for bulk material loading at overseas ore terminals and large-scale mining areas.

The ZRSL-45 Mobile Ship Loader focuses deeply on addressing the pain points of large-scale loading in the bulk material industry (ores, coal, bulk aggregates, etc.). It is primarily adapted for Handysize Max vessels (35,000-50,000 DWT). Its designed clear height of 6-10 meters perfectly matches the hatch height of such vessels and the operating space at terminals, avoiding the issues of "inability to fully load high vessels" and "risk of collision with low vessels" that plague traditional ship loaders.

In terms of cost reduction and efficiency improvement, the equipment is equipped with an automated stockpiling system, which can reduce on-site operators by more than 60% and lower the high labor costs overseas. With pre-wiring design, over 80% of electrical components (such as PLC modules, sensors, and control cables) are pre-wired and debugged before leaving the factory. Only 2-3 days are needed for on-site electrical connection, which shortens the construction time by 70% compared with traditional ship loaders, significantly reducing the installation cycle and communication costs of overseas projects. In addition, the equipment supports modular disassembly and can be transported internationally via 2-3 40-foot high cube containers (HQ Containers), effectively controlling logistics costs.

Core Advantages

Full-Process Automation

The ZRSL-45 Mobile Ship Loader is equipped with ZOOMRY’s self-developed "Intelligent Stockpiling Control System", enabling full-process automation from "material receiving - conveying - in-hold stockpiling":

• Automatic Stockpiling Algorithm: Real-time monitoring of material height in the ship’s hold via laser level sensors. The PLC system automatically adjusts the telescopic length, luffing angle, and belt speed of the ship loader to avoid hold wall collisions caused by excessively high material piles and ship tilting due to uneven stacking (stockpiling accuracy error ≤5%);
• Remote Control Function: Supports wireless remote control within a 100-meter range (standard configuration) or remote operation from the central control room via industrial Ethernet (optional). Operators do not need to be on duty at the loading site with high dust and noise levels, which not only ensures personal safety but also reduces occupational health risks;
• Fault Self-Diagnosis: The system can real-time monitor 12 key parameters such as belt deviation, motor overload, and abnormal hydraulic system pressure. In case of faults, it automatically shuts down and pops up a prompt for the fault point, reducing the downtime of overseas customers caused by "insufficient technical personnel" (average fault repair time is shortened to within 2 hours).

High Adaptability Design

• Ship Adaptability: Through the combination of "telescopic boom + luffing mechanism", the maximum extension length of the telescopic boom can reach 28 meters, covering the full hatch width (18-22 meters) of Handysize Max vessels. Single-hold loading can be completed without moving the entire machine; the adjustable clear height range of 6-10 meters can adapt to the hatch heights of different ship types (e.g., the hatch height of 50,000 DWT vessels is approximately 9 meters, and that of 35,000 DWT vessels is approximately 7 meters);
• Material Adaptability: The machine frame is made of Q355ND high-strength weathering steel (impact strength 30% higher than ordinary carbon steel), which can withstand long-term impact from ores (density 2.5-3.0 t/m³); the belt adopts ST/S800 heavy-duty conveyor belt (tensile strength 800 N/mm) with a wear-resistant rubber coating (15 mm thick) on the surface, preventing scratches on the belt by heavy bulk materials and extending its service life to over 5 years (industry average is 3 years);
• Site Adaptability: Standard wheeled chassis (load-bearing capacity ≥120 t) suitable for hardened terminal pavements; optional tracked chassis (ground pressure ≤0.12 MPa) to cope with soft ground in mining areas (e.g., open-pit mine terminals in Australia and Africa), eliminating the need for site hardening modification and reducing customers’ initial investment.

Rapid Commissioning to Reduce Project Risks

• Pre-Wiring System: All electrical components (such as frequency converters, contactors, and sensors) are pre-wired before leaving the factory and undergo 72 hours of continuous power-on testing. On-site, only the main power supply and control signal lines need to be connected (standardized interfaces are provided, no on-site welding or custom cables required);
• Modular Assembly: The equipment is divided into three major modules: "telescopic boom unit, chassis unit, and hydraulic power unit". The weight of each module is controlled within 30 t (can be hoisted by conventional cranes at terminals), and on-site assembly only takes 5-7 days (traditional ship loaders require 15-20 days);
• Multi-Language Support: The operation interface supports multiple mainstream overseas languages such as English, Russian, and Spanish. Operation manuals and maintenance manuals are available in both paper and electronic versions, facilitating quick mastery by overseas operators.

Core Technical Parameters

The technical parameters of the ZRSL-45 are based on ZOOMRY’s ISO 9001 Quality Management System, with key indicators optimized for heavy bulk material and large-tonnage vessel scenarios:

In addition, customized upgrades for ore characteristics are supported, such as adding wear-resistant liners to the chute (NM450 material, doubling wear-resistant service life) and installing material magnetic separators (to prevent belt damage by metal impurities), so as to meet the technical specifications of customers in different countries (e.g., Australian AS 4024 safety standard, EU EN 12100 mechanical safety standard).

Application Scenarios

Ore Handling at Port Terminals

As key nodes for bulk material export, ore terminals handle materials (mainly ores) with a density usually ranging from 2.5 to 3.0 t/m³, which imposes strict requirements on the structural strength of equipment and the wear resistance of conveying components. Meanwhile, they need to adapt to the varying hatch heights (6-10 m) and widths of 35,000-50,000 DWT Handysize Max vessels. The ZRSL-45 Mobile Ship Loader adopts a machine frame made of Q355ND high-strength weathering steel and is paired with an ST/S800 heavy-duty conveyor belt (tensile strength 800 N/mm) to form a highly wear-resistant conveying system, which can effectively resist structural deformation and belt wear caused by long-term impact from ores.

The intelligent stockpiling control system equipped on the equipment monitors the material status in the hold in real time via laser level sensors. Combined with the PLC system, it automatically adjusts the luffing angle of the telescopic boom (maximum extension length 28 m) and the belt speed, achieving a stockpiling accuracy error of ≤5% and avoiding the uneven stacking issue that is common with traditional manual operations. At the same time, the adjustable clear height design (6-10 m) can flexibly adapt to the hatch differences of different ship types, reducing loading interruptions caused by height adaptation deviations. Combined with the flexible mobility of the wheeled chassis, the equipment adjustment time during single-hold loading is shortened by more than 40%, significantly improving the turnover rate of terminal berths. In response to the high environmental protection and safety requirements of overseas terminals, the equipment can be optionally equipped with a sealed chute and dust removal device to meet dust emission control standards. The full-process automated operation also reduces the safety risk of personnel exposure to high-dust environments.

Large-Scale Mining Transfer

Large-scale mining areas generally feature no stable municipal power supply, unhardened sites (low soil bearing capacity), and the need for short-distance material loading onto ships. The ZRSL-45 Mobile Ship Loader can be equipped with a 120kW diesel generator to form an independent power supply system, freeing it from reliance on municipal power and meeting the demand for 24-hour continuous operation. The intelligent linkage design between the generator and the hydraulic system enables fuel consumption optimization, reducing the operating costs of mining areas.

For soft ground (e.g., temporary stockyards in mining areas), the equipment can be optionally equipped with a tracked chassis (ground pressure ≤0.12 MPa), which can move stably without site hardening modification, avoiding the stagnation problem that is prone to occur with traditional wheeled equipment. In terms of deployment efficiency, the pre-wiring design completes the wiring and debugging of over 80% of electrical components before leaving the factory, requiring only 2-3 days for on-site electrical system connection. Combined with the modular assembly mode of "telescopic boom - chassis - power unit", the overall installation cycle can be controlled within 7 days, which is more than 50% shorter than that of traditional ship loaders. The structural design of the equipment fully considers the high-dust environment in mining areas: key components are treated with dust-proof sealing; vulnerable parts such as idlers and rollers use ZOOMRY’s universal standard parts, reducing the pressure of spare parts inventory; and the fault self-diagnosis system (real-time monitoring of 12 key parameters) significantly reduces the equipment downtime risk in mining areas with "insufficient maintenance personnel", meeting the demand for continuous production.
