High-Efficiency Mobile Shiploaders for Bulk Cargo Handling

Traditional rail-mounted shiploaders, constrained by fixed foundations and rigid structures, often suffer from operational interruptions and efficiency losses when faced with diverse vessel dimensions (such as Panamax and Handysize), tidal fluctuations, and uneven terminal terrain. Zoomry Heavy Industry's innovatively developed mobile shiploader, with its deep integration of dynamic spatial adaptation capabilities and intelligent control algorithms, is exceptionally suited for efficient bulk cargo handling in ports!

Greater Flexibility

Zoomry Heavy Industry's mobile shiploader offers crawler-tracked and wheeled chassis options. Its core utilizes a high-strength carbon steel truss structure paired with multiple hydraulic cylinders, enabling dynamic adjustment capabilities within a ±15° inclination range. When tidal differences reach 3.5 meters, the hydraulic closed-loop control system monitors the relative position between the discharge chute and hatch in real time. Automatic leveling cylinders compensate for vertical height differences, ensuring precise material flow into the vessel hold. Compared to rail-mounted equipment requiring over 12 meters of channel width, the crawler-tracked mobile shiploader achieves 90° turns with just an 8-meter ultra-narrow turning radius, improving terminal frontage space utilization by over 60%. Crucially, the mobile shiploader can freely move on complex terrains with slopes ≤5° via its crawler drive, completing cross-berth transfers within 20 minutes, significantly enhancing multi-vessel parallel operation capabilities. The power module employs an independent dual-pump hydraulic system, with travel speeds of 0-15 m/min continuously variable, while ground pressure is controlled below 80 kPa to prevent damage to terminal surfaces.

Intelligent Control

Zoomry's mobile shiploader features an HMI touchscreen control system with a built-in vessel parameter database covering hatch distribution models for over 200 standard vessel types (e.g., Handysize, Panamax, Capesize). Upon selecting a vessel type, the system combines laser radar-scanned real-time draft data to automatically generate 3D discharge path planning. Its innovation lies in dual-layer control algorithms:

• Static Path Layer: Presets optimal material trajectory based on vessel design blueprints to avoid impact with hatch walls.
• Dynamic Compensation Layer: Real-time monitoring of vessel roll/pitch angles (±8° range) via an Inertial Measurement Unit (IMU) installed at the boom tip. Combined with wind speed sensor data, it dynamically adjusts discharge point coordinates at 100Hz. Field tests show this system reduces material spillage from 15-20% in traditional equipment to below 3%, decreasing cargo repositioning time by 23%. Control modes support seamless switching: PLC full-auto mode enables fully autonomous operations; wireless remote control handles complex boundary conditions; local manual control serves as emergency redundancy. The core controller uses an industrial-grade multi-core processor, ensuring ≤1ms response latency in dusty, high-vibration environments.

Balancing Environmental Performance & Efficiency

The mobile shiploader adopts a dual-section telescopic boom structure. Its embedded STR1600-type steel cord conveyor belt enables a 10-22m stepless telescopic range via a hydraulic winch-driven wire rope system. Combined with a 110° horizontal slewing angle, it covers the entire vessel working area. A breakthrough in eco-efficiency comes from its four-stage sealing system:

1. Tubular Enclosure: Corrugated steel plate + polyurethane elastomer composite structure, bendable to a 30D radius.
2. Head Section: Polyurethane double-blade cleaner with adjustable contact pressure (0.3-0.8 MPa).
3. Tail Section: V-plough cleaner at a 45° angle for return belt cleaning.
4. Empty Section: Dual-axis rotating brushes + high-frequency vibrators to remove residual adhesion.

This system maintains dust emission concentration ≤15mg/m³ during coal handling, with material carryback <0.02%. The power architecture supports diesel/electric dual-mode: Electric mode connects to 6kV high-voltage grids driving a 400kW permanent magnet synchronous motor; Diesel mode uses a Cat C18 engine for power redundancy, with fuel consumption <25L/h. Variable frequency control enables linear throughput adjustment between 300-1,500t/h, providing 18% energy savings over conventional equipment.

Triple Protection for Continuous Operation

The mobile shiploader incorporates three-tiered safeguards: mechanical cable-braking (0.01s response), hydraulic emergency accumulators, and deviation-triggered emergency stops.

• Mechanical Layer: Real-time tension monitoring on boom cables. Upon fracture risk detection, wedge brakes lock within 0.01s (±0.5° accuracy).
• Hydraulic Layer: Dual accumulator groups (total 120L capacity) provide pressure to retract booms safely within 30 minutes during power failure.
• Electrical Layer: Belt deviation sensors, emergency pull-cord switches, and material flow monitors form a triple hardwired interlock. Fault signals transmit via Profibus-DP bus directly to the control room (≤5s delay).

Additionally, its storm anchorage withstands 60m/s wind loads, while radar collision avoidance covers a 30m radius, establishing a comprehensive safety ecosystem.

Model Comparison

Zoomry’s full shiploader series covers vessels from 10,000-120,000 DWT. Taking the ZRSL-60 (designed for Handymax vessels) as an example: it features a working clearance of 9-22m, capacity of 3,500 t/h, and telescopic range of 25-65m. Compared to competitors in its class, it consumes 18% less energy. Differentiating advantages extend to core components: HDPE-coated idlers (150,000-hour lifespan), CEMA C5-grade drums, and triple international certifications (CE/EAC/KCS) ensuring global compliance.

The core of a high-efficiency mobile shiploader lies in merging dynamic spatial adaptability with precision control algorithms. Zoomry Heavy Industry's mobile shiploading equipment redefines physical boundaries via crawler chassis, reduces operational latency with intelligent systems, and balances efficiency with environmental protection through modular design. As ISO 9001/14001 integration deepens, future bulk ports will witness more "zero-intervention" automated handling scenarios.
