Transloading (aka. Cross-Docking) is the process of transferring a shipment from one mode of transportation to another. It is most commonly employed when one mode cannot be used for the entire trip, such as when goods must be shipped internationally from one inland point to another. Such a trip might require transport by truck to an airport, then by airplane overseas, and then by another truck to its destination; or it might involve bulk material (such as coal) loaded to rail at the mine and then transferred to a ship at a port. Transloading is also required at railroad break-of-gauge points, since the equipment can not pass from one track to another unless bogies are exchanged.
Since transloading requires handling of the goods, it causes a higher risk of damage. Therefore, transloading facilities are designed with the intent of minimizing handling. Due to differing capacities of the different modes, the facilities typically require some storage facility, such as warehouses or rail yards. For bulk goods, specialized material handling and storage are typically provided (as, for example, in grain elevators). Intermodal transport limits handling by using standardized containers, which are handled as units and which also serve for storage if needed.
Transloading may be confused with transshipment, but in modern usage they represent different concepts. Transloading concerns the mechanics of transport, while transshipment is essentially a legal term addressing how the shipment originates and is destined. [1] Consider a load of grain that is transloaded at an elevator, where it is combined with grain from other farms and thus leaves on the train as a distinct shipment from that in which it arrived. It thus cannot be said to be transshipped. Or consider a package shipped through a package delivery service or by mail: it may change shipping mode several times along the trip, but since it is (from an external point of view) conveyed as a single shipment regardless of how it is conveyed or what else travels with it on the legs of its journey, it is not considered to be transshipped. Conversely, a load on a truck can be taken in one (legal) shipment to an intermediate point and then to its ultimate destination without ever leaving the truck. If this is specified as two shipments, then the goods are transshipped, but no transloading has taken place.
The modern distinction between transloading and transshipment was not well codified in the period of the mid-19th through mid-20th centuries, when discussions of break of gauge often used the word transshipment for what today's careful usage would call transloading, or for any combination of transloading and transshipment.
Transloading can occur at any place. A truck can pull up to another truck or a train, and transloading may be accomplished by no more elaborate means than teamsters and stevedores. In the interests of speed and efficiency, however, a variety of specialized equipment is used to handle the goods. Thus, intermodal facilities have specialized cranes for handling the containers, and coal piers have car dumpers, loaders, conveyors, and other equipment for unloading and loading railroad cars and ships quickly and with a minimum of personnel. Transloading facilities may also make use of a Bulk Transloading System to provide visibility of a transloading operation including rail, storage, over the road drivers, dray drivers, bookings, and the master load plan. [2]
Often the equipment used to ship the goods is optimized for rapid transfer. For instance, the shipment of automobiles is expedited by autorack rail cars and roll-on/roll-off ships, which can be loaded without cranes or other equipment. Standardized containers allow the use of common handling equipment and obviate break bulk handling.
Transloading is often combined with classification and routing facilities, since the latter often require handling of goods. Transloading may occur at railway sidings and break-of-gauge stations.
Where ports are too small to handle large bulk carrier ships, transloading can occur at sea, using transhipment platforms, ships, or floating cranes and barges. [3]
Freight transport is the physical process of transporting commodities and merchandise goods and cargo. The term shipping originally referred to transport by sea but in American English, it has been extended to refer to transport by land or air as well. "Logistics", a term borrowed from the military environment, is also used in the same sense.
Containerization is a system of intermodal freight transport using intermodal containers. Containerization is also referred as "Container Stuffing" or "Container Loading", which is the process of unitization of cargoes in exports. Containerization is the predominant form of unitization of export cargoes unlike other systems viz the barge system or the palletization. The containers have standardized dimensions. They can be loaded and unloaded, stacked, transported efficiently over long distances, and transferred from one mode of transport to another—container ships, rail transport flatcars, and semi-trailer trucks—without being opened. The handling system is completely mechanized so that all handling is done with cranes and special forklift trucks. All containers are numbered and tracked using computerized systems.
An intermodal container, often called a shipping container or a freight container, is a large standardized shipping container, designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – from ship to rail to truck – without unloading and reloading their cargo. Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the global containerized intermodal freight transport system, but smaller numbers are in regional use as well. These containers are known under a number of names. Based on size alone, up to 95% of intermodal containers comply with ISO standards, and can officially be called ISO containers. Many other names are simply: container, cargo or freight container, shipping, sea or ocean container, container van or sea van, sea can or C can, or MILVAN, SEAVAN, or RO/RO. The also used term CONEX (Box) is technically incorrect carry-over usage of the name of an important predecessor of the international ISO containers, namely the much smaller prior steel CONEX boxes used by the U.S. Army.
A railroad car, railcar, railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck, also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport system. Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some passenger cars are self-propelled in which case they may be either single railcars or make up multiple units.
Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation, without any handling of the freight itself when changing modes. The method reduces cargo handling, and so improves security, reduces damage and loss, and allows freight to be transported faster. Reduced costs over road trucking is the key benefit for inter-continental use. This may be offset by reduced timings for road transport over shorter distances.
Cargo consists of bulk goods conveyed by water, air, or land. In economics, freight is cargo that is transported at a freight rate for commercial gain. Cargo was originally a shipload but now covers all types of freight, including transport by rail, van, truck, or intermodal container. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facility. The term freight is commonly used to describe the movements of flows of goods being transported by any mode of transportation.
Transshipment or transhipment is the shipment of goods or containers to an intermediate destination, then to another destination.
A sidelifter is a specialised vehicle or semi-trailer used to hoist and transport ISO standard intermodal containers over longer distances.
A container crane is a type of large dockside gantry crane found at container terminals for loading and unloading intermodal containers from container ships.
A distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing element, of the entire order fulfillment process. Distribution centers are usually thought of as being demand driven. A distribution center can also be called a warehouse, a DC, a fulfillment center, a cross-dock facility, a bulk break center, and a package handling center. The name by which the distribution center is known is commonly based on the purpose of the operation. For example, a "retail distribution center" normally distributes goods to retail stores, an "order fulfillment center" commonly distributes goods directly to consumers, and a cross-dock facility stores little or no product but distributes goods to other destinations.
Rail freight transport is the use of railroads and trains to transport cargo as opposed to human passengers.
Less-than-truckload shipping or less than load (LTL) is the transportation of an amount of freight sized between individual parcels and full truckloads. Parcel carriers handle small packages and freight that can be broken down into units less than approximately 150 pounds (68 kg). Full truckload carriers move entire semi-trailers. Semi-trailers are typically between 26 and 53 feet and require a substantial amount of freight to make such transportation economical. The term LTL can refer to the freight itself, or to the carrier that transports the such freight.
Johor Port is a port in Pasir Gudang, Johor, Malaysia, built in 1977. It is an integrated multi-purpose port facility providing bulk cargo, container and general cargo services. It is the world's largest palm oil terminal and ranks third globally in terms of LME cargo volume.
In shipping, break-bulk, breakbulk, or break bulk cargo, also called general cargo, refers to goods that are stowed on board ship in individually counted units. Traditionally, the large numbers of items are recorded on distinct bills of lading that list them by different commodities. This is in contrast to cargo stowed in modern intermodal containers as well as bulk cargo, which goes directly, unpackaged and in large quantities, into a ship's hold(s), measured by volume or weight.
A goods station or freight station is, in the widest sense, a railway station where, either exclusively or predominantly, goods, such as merchandise, parcels, and manufactured items, are loaded onto or unloaded off of ships or road vehicles and/or where goods wagons are transferred to local sidings.
A berth is a designated location in a port or harbour used for mooring vessels when they are not at sea. Berths provide a vertical front which allows safe and secure mooring that can then facilitate the unloading or loading of cargo or people from vessels.
A shipping container is a container with strength suitable to withstand shipment, storage, and handling. Shipping containers range from large reusable steel boxes used for intermodal shipments to the ubiquitous corrugated boxes. In the context of international shipping trade, "container" or "shipping container" is virtually synonymous with "intermodal freight container", a container designed to be moved from one mode of transport to another without unloading and reloading.
Corrugated box design is the process of matching design factors for corrugated fiberboard boxes with the functional physical, processing and end-use requirements. Packaging engineers work to meet the performance requirements of a box while controlling total costs throughout the system.
A Terminal Operating System, or TOS, is a key part of a supply chain and primarily aims to control the movement and storage of various types of cargo in and around a port or marine terminal. The systems also enables better use of assets, labour and equipment, plan workload, and receive up-to-date information.
Container port design process is a set of correlated practices considered during container port design, aiming to transfer general business mission into detailed design documents for future construction and operation.
