Explore our benchmark continuous mechanical screw ship unloading equipment operating across major maritime hubs and river terminals.
Understanding the core engineering assemblies of Chinese continuous screw ship unloaders. Every component is precision-crafted with high-strength alloy materials and intelligent PLC controls to withstand harsh maritime environments.
The digging unit located at the lower end of the vertical arm. Equipped with counter-rotating feeder blades that dig deep into bulk piles (cement, coal, clinker), providing constant fluidization and pushing cargo into the vertical screw with minimal barge residue.
A fully enclosed cylindrical casing with high-speed internal screw flights made of wear-resistant alloy (Hardox / Chromium carbide overlay). It lifts granular and powdery materials vertically from vessel holds up to 35 meters high without producing fugitive dust.
Transfers cargo from the vertical arm to the central gantry hopper. Features a 360-degree slew ring drive and heavy-duty hydraulic luffing cylinders that allow the arm to reach all corners of Supramax, Panamax, or Indonesian domestic river barges.
Integrates Siemens/Schneider PLC with intelligent anti-collision radar, automatic hold profiling, real-time weighing sensors, and variable frequency drives (VFD) to optimize power consumption during fluctuating barge tide levels in Indonesian waters.
Available in Rail-Mounted (rel gantry), Rubber-Tyred Mobile (roda ban), or Fixed Pedestal configurations. Engineered with wind-resistant hydraulic rail clamps designed to sustain tropical cyclone wind gusts common in Southeast Asian coastlines.
Equipped with pulse-jet cartridge dust collectors, sealed telescopic transfer chutes, and negative-pressure transfer points. Meets strict Indonesian environmental thresholds (KLHK / AMDAL standards) for zero particulate spillage into the marine ecosystem.
As the world's largest archipelagic nation, Indonesia heavily relies on maritime trade and inter-island bulk transportation (Tol Laut). Rapid industrialization across Java, Sumatra, Kalimantan, and Sulawesi has dramatically surged the demand for modern, high-throughput ship unloading systems.
Traditional grab cranes (crane grab konvensional) frequently suffer from severe dust pollution, high material spillage rates, and sluggish cycle times. With the Indonesian Ministry of Environment and Forestry (KLHK) implementing stricter AMDAL emissions regulations, terminal operators and industrial plants are rapidly upgrading to enclosed continuous screw ship unloaders (*continuous mechanical ship unloader*).
Continuous unloading rates up to 2,000 tons/hour, enclosed dustless operation, reduced ship demurrage costs at busy ports like Tanjung Priok, Tanjung Perak, Morowali, and Batam.
1. Cement & Infrastructure (Semen Indonesia, Indocement, Semen Merah Putih): Unloading cement clinker, finished cement, GGBS (Ground Granulated Blast-furnace Slag), and fly ash for mega-infrastructure projects including the IKN Nusantara capital city.
2. Nickel Smelters & Mineral Hubs (Morowali, Weda Bay, Konawe): Continuous handling of thermal coal, limestone flux, and auxiliary powders required for metallurgical smelter operations.
3. Fertilizer Terminals (Pupuk Indonesia Group): Moisture-proof, gentle handling of bulk urea, NPK, and DAP at plants across Palembang, Gresik, and Bontang without hygroscopic clogging.
4. Coal-Fired Power Plants (PLN & IPP Terminals): Enclosed transfer of bituminous and sub-bituminous coal to prevent spontaneous ignition and coastal water contamination.
We specialize in providing overall solutions for bulk material transfer, storage, and transportation systems, as well as the R&D, design, manufacturing, and sales of high-end loading and unloading equipment for powdery and granular bulk materials in domestic and international maritime markets.
Technical comparison between modern China Continuous Screw Ship Unloaders and traditional Grab Cranes operating in Indonesian coastal terminals.
| Performance Metric | Continuous Screw Ship Unloader (AOTUO China) | Conventional Grab Crane (Grab Bucket) | Benefit for Indonesian Terminal Owners |
|---|---|---|---|
| Environmental / Dust Control | 100% Fully Enclosed Negative Pressure (0 mg/m³ fugitive dust) | Open air grab drop, severe airborne dust spillage | Full compliance with Indonesian AMDAL / KLHK green standards |
| Unloading Efficiency | Continuous steady flow rate (up to 2,000 T/H) | Cyclic peak & valley flow, slow turnaround times | Reduces vessel berthing demurrage costs by over 45% |
| Hold Cleanout & Residue | Counter-rotating feeding head scrapes down to 10-15cm | Leaves 1.5 - 2.5 meters pile residue, requires manual bobcat | Saves 60% cleanup labor and expedites barge turnaround |
| Weather Adaptability | Operates in high tropical rainfall without moisture ingress | Must shut down hatch in heavy tropical rains | Maximizes annual operational uptime in monsoon seasons |
| Material Degradation | Gentle spiral rotation, low breakage velocity | High impact drop causing severe grain/clinker breakage | Protects valuable agricultural and chemical cargo quality |
The company's products and services have been exported to countries such as Australia, Korea, Singapore, the Philippines, Vietnam, Malaysia, Indonesia, Sri Lanka, and Russia, and are highly acclaimed by maritime terminal authorities and industrial EPCs worldwide.
Select from our industry-proven rail-mounted, fixed pedestal, vehicle-mounted, and track-mounted continuous screw ship unloader product series engineered for heavy-duty bulk handling.
