In global trade and resource transportation, the efficiency of bulk material handling at ports and terminals directly impacts supply chain costs and vessel turnaround speed. Traditional fixed equipment often suffers from rigid layouts and limited flexibility, struggling to cope with diverse vessel types, constrained quayside space, and fluctuating cargo throughput. ZOOMRY Heavy Industry, leveraging its deep expertise in bulk material handling equipment, has innovatively integrated wheeled/crawler truck unloaders with fully hydraulic mobile shiploaders to provide global port operators with an efficient, flexible, and intelligent material handling solution.

What Are the Pain Points in Port Bulk Handling?

Key Challenges

1. Space constraints: Narrow operational areas in aging terminals or inland ports hinder deployment of large fixed loading equipment.
2. Vessel diversity: Handling vessels ranging from barges to Capesize bulk carriers requires shiploaders with wide height adjustment (e.g., 8m–16m) and precise hatch positioning.
3. Unloading bottleneck: Long truck queues, inefficient manual unloading, and high labor costs create logistics bottlenecks at the receiving end.
4. Poor material flow coordination: Remote or poorly designed unloading/loading points force reliance on secondary truck transfers, increasing costs and pollution.
5. Environmental pressure: Open operations generate dust and noise, demanding sealed conveying systems and dust suppression for regulatory compliance.

The Collaborative Solution

ZOOMRY's integrated approach creates a closed "unload-convey-load" loop that eliminates secondary handling and maximizes throughput:

1. Efficiency leap: Truck unloaders achieve up to 1,800 TPH throughput, while mobile shiploaders serve vessels up to Capesize, forming a seamless loading chain.
2. Space optimization: Mobile units require no fixed foundations, enabling flexible relocation to maximize limited dock space. Crawler configurations operate seamlessly on rough terrain.
3. Smart connectivity: Truck unloader discharge chutes directly feed mobile shiploader hoppers (10m³+) or use portable grasshopper conveyors for short-distance transfers, eliminating secondary trucking entirely.
4. Multifunctionality: Mobile shiploaders double as radial stackers for yard storage during non-loading periods, maximizing equipment utilization.
5. Green intelligence: PLC automation, enclosed conveyors, PU Belt Cleaners, and dust control chutes significantly reduce emissions and noise.

How Does Each Piece of Equipment Work?

Truck Unloader — High-Speed Receiving

Replacing manual or excavator unloading, truck unloaders allow dump trucks to ascend a hydraulic ramp and discharge bulk materials (ore, coal, grain, aggregates) into a receiving hopper for rapid conveyor transfer. Taking the ZOOMRY ZRLD-TU1800 Crawler Truck Unloader as an example:

• Adaptability: Crawler undercarriage handles muddy or uneven port terrain without site preparation.
• High-capacity hopper: Low-profile, wide-opening design (up to 5.7m width) accommodates heavy trucks at a 6.7° incline.
• Efficient conveying: 1,800mm belt width, 1,800 TPH capacity with adjustable speed to match downstream equipment.
• Smart control: Full-function remote control enables safe operator monitoring of ramp elevation and conveyor operation.
• Custom screening: Adjustable grids prevent oversized material blockages, protecting downstream conveyors.

Mobile Shiploader — Precision Vessel Loading

ZOOMRY's mobile shiploaders integrate travel, rotation, pitch, and telescoping to accurately load bulk materials from upstream systems into vessel holds. Taking the ZOOMRY ZRSL Series as an example:

• Universal compatibility: Modular ZRSL-40 to ZRSL-60 models serve barges to Capesize ships with 0–16m+ height adjustment.
• Radial telescoping boom: Hydraulic winch extends inner conveyor (10–22m), working with rotation for full hatch coverage, minimizing vessel shifts.
• Safety redundancy: Dual rope-break protection (mechanical + hydraulic lock, 0.01s response), belt sway switches, emergency pull cords.
• Automation: PLC auto-loading system with HMI presets vessel profiles, automating travel, rotation, and material flow for precision loading.
• Power options: Diesel genset or shore power for off-grid or environmentally regulated port areas.

How Does the Truck-to-Ship Workflow Operate Step by Step?

Step 1: High-Speed Truck Unloading

• Material-laden dump trucks ascend the crawler truck unloader's hydraulic ramp.
• Operators remotely control ramp elevation for controlled hopper discharge.
• Bottom conveyor (1,800mm width) transfers material at up to 1,800 TPH.

Step 2: Flexible Material Transfer (Optional)

For distant unloading points, crawler grasshopper conveyors bridge gaps to shiploader hoppers with adjustable discharge heights, maintaining continuous material flow across the quayside.

Step 3: Precision Loading by Mobile Shiploader

• The mobile shiploader autonomously moves to the designated berth via its crawler or wheel system.
• Operators select the target vessel type and preset program from the HMI touchscreen.
• The PLC system precisely coordinates positioning, boom rotation, pitch angle adjustment (based on real-time tidal changes and vessel draft), and conveyor extension directly above the hatch.
• Material enters the shiploader's receiving hopper and is discharged into the cargo hold. The PLC automatically controls boom movement based on material accumulation patterns, ensuring even distribution.
• Upon completing one hold, the shiploader moves or rotates to proceed with the next hold — without vessel repositioning.

Synergy Benefits

• Efficiency: Matched unloader/shiploader capacities eliminate bottlenecks — trucks unload in minutes, not hours.
• Zero retransfer: Direct conveyor transfer cuts trucking costs, tire wear, fuel consumption, and CO₂ emissions.
• Flexibility: Rapid reconfiguration for varying berths, cargo types, or seasonal throughput changes.
• Labor savings: Remote and PLC automation reduces onsite personnel requirements and safety risks.
