Cost effective Ways to Unload Aggregate from Self-unloading Vessels

Efforts to minimize overall transportation-related costs remain critical for all relevant stakeholders. As a fundamental resource in the construction supply chain, there is always an emphasis on enhancing its movement and handling to streamline operations and reduce labor and time expenditures. Our mobile hopper feeder (or mobile hopper) and radial telescopic stacker can form a flexible aggregate unloading and stacking system.

Traditionally, aggregate transportation in Europe has relied heavily on truck and rail systems. However, growing concerns about environmental impact, road congestion and pollution have prompted companies to explore environmentally friendly, efficient alternatives such as maritime shipping.

Maritime Bulk Materials Transportation

Utilizing self-unloading vessels for aggregate cargo transportation offers significant benefits for companies seeking environmentally sustainable shipping solutions. Belt self-unloading technology efficiently handles various materials, from crushed limestone to sand, gravel, and stone, reducing costs by minimizing labor requirements. Established short sea shipping routes in the North Sea, Atlantic Ocean, and Mediterranean provide a robust transportation network, complemented by the development of self-unloading vessels designed to facilitate the process.

Traditional Methods of Unloading Bulk Materials

Equipped with long discharge booms and integrated conveyor belts, belt self-unloading vessels smoothly deliver aggregate cargo from the holds to the shore at rates exceeding 3,000 tonnes per hour. However, difficulties arise at ports during the handling of aggregates from the discharge point onward to storage or trucks for ongoing transport. Typically, dedicated fixed hopper and conveyor systems move materials to storage areas, requiring specific infrastructure and limiting the flexibility of shipowners/operators and port authorities.

Alternatively, without fixed infrastructure, materials are transferred directly to the ground and handled using wheel loaders, grapples and trucks. However, handling high tonnages of up to 3,000 tonnes per hour can present challenges, leading to increased costs and safety issues.

Flexible Method to Transfer Bulk Materials from Self-unloading Ships

To address these challenges, MNSTACKER offers a solution utilizing a mobile conveyor system directly from the discharge point to the storage area, eliminating the need for additional resources. The mobility of these conveyor systems allows for versatility in operation, making them suitable for multi-cargo berths lacking dedicated unloading facilities.

MNSTACKER's range of designs accommodates varying handling rates and vessel sizes, ensuring efficient handling from smaller to the largest self-unloading vessels. Benefits include cost reduction, elimination of double/triple handling, enhanced safety, and reduced emissions through electric-driven units and dust control management options.

We provide mobile aggregate handling system tor aggregate unloading. You can use our mobile hopper and mobile hopper feeder to receive bulk materials from discharging belt of self-unloading ships.
