ZRSL-50 mobile shiploader

The ZRSL-50 Mobile Ship Loader focuses closely on 60,000-80,000 DWT Panamax vessels at large overseas ports. Its designed clear height of 10-14 meters can accurately match the hatch height of Panamax vessels (typically 12-13 meters), avoiding the "loading interruptions caused by hatch adaptation deviations" that are common with traditional ship loaders. Meanwhile, in response to the demand for "continuous operation with minimal downtime" at large ports, it adopts an optimized hydraulic power pack design and a lattice frame structure, fundamentally reducing the risk of failures, simplifying maintenance procedures, and helping customers improve bulk material loading efficiency (loading efficiency is increased by more than 25% compared with traditional equipment of the same tonnage).

In terms of application adaptability, the ZRSL-50 fully considers the actual scenarios of large ports: it supports modular disassembly for transportation (international logistics can be completed via 4-5 40-foot high cube containers), reducing transoceanic transportation costs; it is compatible with the existing power supply systems of ports (380V/400V 50Hz or 60Hz), eliminating the need for additional power facility modifications; the operation interface supports multiple mainstream overseas languages such as English, Korean, and Spanish, adapting to the usage habits of port operators in different countries and enabling quick mastery without a learning curve.

Core Advantages

Meeting Heavy-Tonnage High-Efficiency Loading Needs

Targeting the loading requirements of 60,000-80,000 DWT Panamax vessels, the ZRSL-50 has undergone exclusive optimizations in structure and function:

• Full Hatch Coverage Design: The maximum telescopic boom extension length reaches 35 meters, which can cover the full hatch width (24-28 meters) of Panamax vessels. Single-hold loading can be completed without frequent movement of the entire machine, reducing equipment adjustment time (single-hold loading efficiency is increased by 30%);
• High Load-Bearing Structure: The machine frame is made of Q460QC high-strength bridge steel (yield strength ≥460MPa), which can withstand long-term impact and pressure from ores (density 2.8-3.2 t/m³). The rated load-bearing capacity of the entire machine reaches 180 tons, meeting the demand for continuous transportation of heavy-tonnage bulk materials;
• Multi-Mode Loading: It supports three modes: "fixed-point loading", "reciprocating stacking", and "layered stacking". These modes can be switched according to the characteristics of different bulk materials (e.g., coal is prone to dust emission, while ore is prone to accumulation), avoiding ship stability issues caused by material segregation or uneven in-hold accumulation. The loading qualification rate reaches over 99.5%.

Low Failure Rate for Continuous Operation

• High-Performance Core Component Configuration: The hydraulic power pack combines precision piston pumps and high-efficiency hydraulic motors. Key sealing components are made of high-elasticity, medium-resistant materials, which can maintain stable sealing performance under working conditions with frequent temperature and pressure changes, effectively reducing the risk of leakage. Through optimized hydrodynamic design and precision manufacturing processes, the component failure rate is reduced by 60% compared with traditional configurations. Calculated in accordance with the international MTBF (Mean Time Between Failures) reliability standard, the mean time between failures has been increased from 3,000 hours to 8,000 hours, significantly reducing unplanned downtime caused by hydraulic system failures. This high-reliability configuration enables the equipment to maintain stable power output even in heavy-load continuous operation scenarios, making it particularly suitable for the long-term uninterrupted loading needs of large ports.
• Intelligent Temperature Control and Filtration: Equipped with a dual-circuit cooling system (air cooling + water cooling) to ensure that the hydraulic oil temperature is stabilized at 35-55℃ (avoiding seal aging caused by high temperatures); at the same time, a three-stage filtration system (suction filtration, return filtration, high-pressure filtration) is adopted, and the hydraulic oil cleanliness reaches NAS Class 8, reducing hydraulic valve clogging failures;
• Fault Early Warning Function: The PLC system monitors parameters such as hydraulic system pressure, temperature, and oil level in real time. When abnormalities occur, pop-up warnings are issued 15-30 minutes in advance (e.g., low oil level, pressure fluctuations), reserving processing time for maintenance personnel and avoiding sudden downtime.

Simplified Maintenance to Reduce Labor Costs

• Modular Detachable Structure: The machine frame adopts a lattice-frame modular design, with each module weighing no more than 25 tons (can be hoisted by conventional port cranes). When replacing damaged components, there is no need to disassemble the entire machine, reducing maintenance time by 50% (e.g., replacing the telescopic boom support rollers takes 8 hours for traditional equipment, but only 4 hours for the ZRSL-50);
• Full-Range Maintenance Access Routes: 1.2-meter-wide maintenance access routes (equipped with non-slip pedals and protective railings) are set on both sides of the lattice frame. Maintenance hatches are reserved for key components (such as hydraulic cylinders and idler groups), allowing maintenance personnel to perform inspections and replacements without climbing or entering the interior of the equipment, improving operational safety;
• Universalization of Wear Parts: Wear parts such as idlers and cleaning scrapers are designed in accordance with ZOOMRY's universal standards and are compatible with the wear parts of ZOOMRY's belt conveyors and telescopic stackers. This reduces the types of spare parts in port inventory (spare parts inventory costs can be reduced by 30%) and facilitates quick replacement.

Core Technical Parameters

The technical parameters of the ZRSL-50 are optimized based on ZOOMRY's ISO 9001 Quality Management System and the operational needs of large ports. Key indicators have passed third-party testing and certification, with details as follows:

In addition, customized upgrades for large ports are supported, such as adding chute anti-clogging devices (equipped with high-frequency vibrators to prevent material clogging), installing dust collection systems (complying with EU EN 15237 dust emission standards), and adapting to port central control systems (supporting Modbus TCP protocol for remote monitoring and data upload), to meet the technical specifications of ports in different countries (e.g., South Korea's KOSHA safety standards, EU EN 13000 mechanical standards).

Typical Application Scenarios

With its accurate adaptation to 60,000-80,000 DWT Panamax vessels, low failure rate of the hydraulic system, and easy maintenance of the lattice frame design, the ZRSL-50 Mobile Ship Loader can deeply meet the loading needs of different heavy bulk materials at large overseas ports. It specifically addresses operational pain points in various scenarios, becoming a core supporting equipment for large-scale bulk material loading.

Large-Scale Ore Ports

The core needs of large-scale ore ports (for iron ore, copper ore, etc.) are "high load-bearing capacity, continuous operation, and minimal downtime" — the density of ores generally reaches 2.8-3.2 t/m³, which imposes extremely high requirements on the structural strength of equipment. Moreover, most ports need 24/7 continuous loading to ensure shipping schedules. The ZRSL-50 Mobile Ship Loader uses Q460QC high-strength bridge steel for its machine frame, with a rated load-bearing capacity of 180 tons, which can withstand long-term ore impact without deformation. Its 35-meter ultra-long telescopic boom can fully cover the 24-28 meter hatch width of Panamax vessels, allowing single-hold loading without frequent movement of the entire machine, greatly reducing equipment adjustment time and increasing loading volume per unit time. At the same time, the optimized hydraulic power pack has a mean time between failures of 8,000 hours, which can effectively avoid loading interruptions caused by equipment failures, meeting the "continuous, efficient, and stable" operational requirements of ore ports and complying with the strict standards for equipment load-bearing strength and operational reliability at ore ports in most countries.

Large-Scale Coal Ports

As a dust-prone bulk material, coal must comply with dust emission requirements such as EU EN 15237 and South Korea's KOSHA standards. Meanwhile, Panamax vessels transporting coal have high requirements for loading efficiency (to avoid additional costs caused by ship detention at ports). The ZRSL-50 Mobile Ship Loader can accurately match the hatch height of coal transport vessels through its adjustable clear height of 10-14 meters. Combined with the reciprocating stacking mode of the telescopic boom, it can achieve uniform coal accumulation, reducing in-hold spillage caused by uneven stacking (spill rate can be controlled within 0.5%) and lowering material loss. The equipment can be optionally equipped with a dust collection system, and through sealed belt conveying + negative-pressure dust suction design, the operating dust concentration is controlled below 10 mg/m³, meeting overseas environmental regulations. In addition, the intelligent temperature control and three-stage filtration design of the hydraulic system can ensure stable power during coal loading, avoiding loading stagnation caused by hydraulic failures and adapting to the operational goals of coal ports of "priority to efficiency and compliance with environmental standards".

Bulk Aggregate Ports

The operational characteristics of bulk aggregate ports (for sand, cement clinker, limestone, etc.) are "alternating loading of multiple materials and high maintenance frequency" — different aggregates have significant differences in physical properties (e.g., sand requires high wear resistance, while cement clinker is prone to moisture absorption and caking), and ports need to frequently replace wear parts to ensure operational continuity. The ZRSL-50 Mobile Ship Loader adopts a modular design: on the one hand, core components can be customized according to aggregate types (e.g., ST/S1000 heavy-duty wear-resistant belts for sand, and chute anti-clogging vibrators for cement clinker), adapting to the needs of multi-material loading; on the other hand, the lattice-frame machine frame is equipped with 1.2-meter-wide maintenance access routes and maintenance hatches for key components. When replacing wear parts such as idlers and cleaning scrapers, there is no need to disassemble the entire machine, reducing maintenance time by 50%. Additionally, the wear parts of the equipment are compatible with ZOOMRY's belt conveyors and telescopic stackers, which can reduce the types of spare parts in port inventory and lower maintenance costs. At the same time, the equipment is compatible with the existing power supply systems (380V/400V 50Hz/60Hz) and central control systems (supporting Modbus TCP protocol) of ports, enabling quick integration into port operation processes without additional modifications and adapting to the operational needs of bulk aggregate ports of "flexible switching and convenient maintenance".
