INTRODUCTION

The grab pneumatic ship unloader is a high-efficiency bulk material handling system combining a mechanical grab (clamshell bucket) with a pneumatic conveying pipeline. The grab digs into the ship’s hold to collect coal, grain, cement, or other powdered/granular materials, then feeds them into a suction nozzle where powerful air flow transports the material through sealed pipes to shore storage. Typical capacities range from 300 t/h to 2,000 t/h, handling vessels up to 100,000 DWT. This unloader minimizes dust emission and product loss, making it ideal for environmentally sensitive ports.

APPLICATION SCENARIO

[1] Bulk Cargo Terminals – Unloading coal, iron ore, and grain from large ocean-going vessels.

[2] Cement and Clinker Terminals – Dust-free transfer of powdery materials from ship holds to silos.

[3] Grain Import Ports – Gentle handling of soybeans, corn, and wheat with low breakage.

[4] Fertilizer and Chemical Ports – Pneumatic conveying prevents contamination and moisture. [5] Power Plant Coal Jetty – Supplying coal to conveyors with reduced dust and spillage.

ADVANTAGES

[1] High Efficiency – Continuous grab feed + pneumatic transport achieves steady, high unloading rates.

[2] Low Dust Emission – Sealed pipeline system prevents dust pollution, meeting strict environmental regulations.

[3] Low Material Loss – Spillage and wind loss are minimized; clean operation.

[4] Gentle on Materials – Pneumatic suction reduces product degradation compared to mechanical impact.

[5] Compact Design – Small footprint on quayside compared to belt conveyor unloading systems.

Six core advantages

Full Scenario Coverage

Nucleon covers over 20 product categories including ladle cranes, multi-purpose cranes, intelligent cranes, overhead/portal cranes, RTG, RMG, deck cranes, portal cranes, girder launchers, yacht cranes, KBK, and jib cranes. From steel smelting to port handling, bridge construction to ship equipment, Nucleon provides one-stop lifting solutions. Whether standard models or extreme-condition customizations, Nucleon possesses mature technical expertise and proven track records, saving customers from dealing with multiple suppliers.

Military-Grade Quality Standards

We use high-strength steel from Baosteel/Ansteel for key structural components, with 100% NDT inspection and one-clamp CNC gantry machining. Every machine undergoes 120% dynamic load and 125% static load tests before delivery, with continuous operation verification under extreme conditions. Even in 24/7 continuous casting plants, -40°C arctic ports, or high-temperature humid ship cabins, our cranes maintain millimeter-level precision and zero-drift stability—quality that stands the test of time.

Extended Longevity & Low Maintenance Cost

Our main girders are FEA-optimized and double-submerged arc welded, with a design life of ≥30 years. Key bearings are lifetime lubrication-free, and hardened travel wheels extend wear cycles by 3 times. Core components feature modular quick-change interfaces with spare parts commonality exceeding 80%. Annual maintenance costs are reduced by 40%~60%, saving millions in lifecycle operating expenses — truly "invest once, benefit long-term."

Energy Efficiency Leader

Our entire series comes standard with IE5 permanent magnet synchronous motors + energy feedback VFD drives, achieving 25%~35% comprehensive energy savings. Single-motor operation under light loads and adaptive speed control reduce electrical waste by over 30%. High-strength steel lightweight design cuts deadweight by 15%~20%, lowering workshop load requirements. A single ladle crane station saves over RMB 150,000 in electricity costs annually, helping customers achieve green and low-carbon production.

Ultimate Safety Redundancy Design

Our hoisting mechanism comes standard with dual brakes + mechanical overspeed switch + triple limit switches, featuring multiple redundant interlocks to prevent load dropping and over-traveling. Large products use box girder torsion-resistant structures, remaining stable even in level 8 gusty winds. Optional intelligent safety monitoring systems detect anomalies in load, skew, wind speed, etc., with automatic alarms and shutdowns. Overall safety redundancy coefficient > 2.0, maintaining zero crane safety incidents for many consecutive years.

Deep Customization & Full Lifecycle Service

We provide complete front-end support from site survey and mechanical simulation to civil review, delivering custom drawings within 2 weeks, with non-standard lead times only 5~7 days longer than standard products. We establish lifelong digital dossiers for customers, warning of end-of-life components 3 months in advance. Our full lifecycle services cover installation training, regular inspections, and remote O&M. With customer repeat purchase rates exceeding 85% for five consecutive years, we are a trustworthy long-term partner.
