Overall, drayage containers are a fundamental component of the logistics and transportation industry, helping to ensure the efficient and timely movement of goods within the supply chain. They are a crucial link that connects different transportation modes and facilitates the seamless flow of cargo from one point to another, contributing to the success of global trade and commerce.

Drayage vs. Intermodal

Drayage and intermodal transportation are two terms often used in the logistics and transportation industry, and they are closely related but represent different aspects of the supply chain. Let’s explore the key differences between drayage and intermodal transportation:

Drayage : Drayage refers to the short-distance movement of goods or containers between a transportation hub, such as a port, rail yard, or distribution center, and their final destination, often within the same metropolitan area or region. Drayage is typically conducted using trucks or other motor vehicles and is a critical link in the supply chain for moving cargo over relatively short distances.

Intermodal Transportation: Intermodal transportation involves the use of multiple modes of transportation, such as ships, trains, trucks, and sometimes even airplanes, to move cargo from its point of origin to its final destination. It encompasses the entire process of containerized cargo moving seamlessly between different modes of transportation.

Distance

Drayage : Drayage is primarily focused on short-distance transportation, typically within a radius of 100 miles or less. Its purpose is to bridge the gap between a transportation hub and the local delivery or pickup location.

Intermodal Transportation: Intermodal transportation can involve long-distance movement of cargo, including international shipping, as it covers the entire journey from the point of origin (e.g., a factory in one country) to the final destination (e.g., a warehouse or store in another country).

Role in the Supply Chain

Drayage : Drayage is a crucial component in the supply chain that ensures the efficient transfer of cargo between different transportation modes and the final destination. It plays a pivotal role in connecting international shipping to domestic distribution networks.

Intermodal Transportation: Intermodal transportation encompasses the broader logistics process, including ocean shipping, rail transport, trucking, and sometimes air freight. It involves coordinating and optimizing the use of these various modes to move cargo from one region or country to another.

Equipment

Drayage : Drayage typically involves the use of drayage containers, which are often standard ISO containers, designed for short-distance transport and compatibility with trucks. These containers are suitable for local distribution and short-haul transportation.

Intermodal Transportation: Intermodal transportation involves various types of containers, including standard ISO containers, refrigerated containers, and specialized containers for different types of cargo. These containers are designed to be compatible with different modes of transportation and international shipping.

In summary, drayage is a specific subset of transportation that focuses on the short-distance movement of cargo within a local or regional area, often connecting transportation hubs with final destinations. Intermodal transportation, on the other hand, encompasses the broader logistics process of moving cargo across long distances, involving multiple modes of transportation and international shipping. Both drayage and intermodal transportation are essential for the efficient and seamless movement of goods in today’s global supply chain.

What is an Drayage Container?

Drayage Containers are also known as shipping containers, and are the cargo containers that allow goods to be stored for transport in trucks, trains and boats, making drayage transport possible.  They are typically used to transport heavy materials or palletized goods.  These containers have revolutionized global trade by providing a simple, efficient, and cost-effective way to move goods from one place to another.

Here, we will explore what drayage containers are, their history, and their role in the modern global supply chain.

Drayage Containers are large, steel boxes designed to transport goods by sea or land. They have become an integral part of the global economy, enabling businesses to transport goods across oceans and continents with ease. Drayage Containers are ubiquitous in ports around the world, stacked high on container ships and transported across the globe.

Drayage Containers are also referred to as shipping container, ISO container, conex box, railroad container, and certain truck trailers. This industry term refers to the International Standards Organization (ISO), the largest developer of international standards and the organization that developed the standard dimension specifications (commonly 10 feet, 20 feet, 40 feet) for steel shipping containers used worldwide.  Drayage containers are standardized metal boxes that are used to transport goods and materials across the world. They come in various sizes and are designed to be easily loaded and unloaded from ships, trains, and trucks, making them ideal for use in the global supply chain. Drayage containers are constructed from durable materials, making them weather-resistant and able to withstand the rigors of long-distance transportation. This ensures that the goods and materials inside are protected during transit.

The design of the ISO standard containers allows for drayage shipping, which is the movement of containers from one mode of transport to another, like ship, rail, or truck, without the need of having to load and unload, and reload its contents.

History of Containers

In the world of logistics and transportation, the humble shipping container has played a transformative role in global trade. Among the various types of containers, drayage containers occupy a unique niche. They have a rich history that spans decades, reflecting the evolution of modern supply chains.

There are different types of Drayage Containers for different types of transportation:

Common Types of Drayage Containers or Shipping Containers

Drayage Containers are another name for the standard shipping containers most used on the market.  Intermodal Containers are typically suitable for any type of dry cargo: pallets, boxes, bags, machines, furniture, etc.

Common types include:

• Dry Storage Container
• Refrigerated Container
• Open top container
• Flat rack container
• Open Side Container
• Tanks Container
• Ventilated containers

Dry Storage Drayage Container

Dry Storage Drayage shipping containers are your typical standard shipping containers.  Basic construction is made of steel, and hermetically sealed, without cooling or ventilation.  Sizes typically come in 20 ‘, 40’ or 40 ‘High Cube.  The High Cube category facilitates an increase of 13% of the internal cubic capacity and can handle the heaviest loads (coal, tobacco, etc.)

Refrigerated Drayage Container

Reefer Drayage Containers provide a temperature-controlled environment. They have a power supply that connects to energy sources during transport. This allows the products to be transported at a constant temperature throughout the journey. They have the possibility to lower temperature from -18 ° to 30 °.  There are 20 and 40-foot models, in addition to the High Cube.

This type of Drayage Container is especially recommended for transporting food or products that need a low storage temperature.

Open Top Drayage Container

Open Top Drayage Containers have the same measurements as the standard containers but are open at the top because they have a removable canvas roof.  These containers facilitate the transport of bulky loads.

Flat Rack Drayage Container

Flat Rack Drayage Containers are like the Open Top, but also lack sidewalls and even, in some cases, front and rear walls. They are used for atypical loads and pay supplements in the same way as Open Top.

Open Side Drayage Container

Open Side Drayage Containers have the same measurements as standard containers; 20 or 40 feet, with the difference that they have a side opening. This allows for transporting very long merchandise, whose dimensions prevent it from being loaded by the back door.

Tank Drayage Container

Tank Drayage Containers are used for liquid transport and made to carry dangerous as toxic, corrosive, highly combustible chemicals, as well as oil, milk, beers, wine, mineral water, etc. They have the same dimensions as Dry Drayage Containers, but their structure is different, as they include a polyethylene tank inside.

Ventilated Drayage Containers

Ventilated Drayage Containers are made for transporting products such as coffee or cocoa beans, which must be ventilated in transit; sometimes these units are called “coffee containers”.

Drayage Container
Opening and Closing Tool

An Drayage Container (also known as Conex Box, ISO Container,Railroad Container, and certain Truck Trailers)  is a large standardized shipping container, designed and built for drayage freight transport.  Drayage Containers can be used across different modes of transport.  They can go from ship to rail to truck, without unloading and reloading their cargo.

The metal doors on the shipping containers on containers are standardized.  Drayage Containers use the same type and style of doors and locking bars, which our tool can be used.

Lengths are as follows: 20′, 40′, 45′, 48′, 50′, 53′. All these containers are globally used to transport cargo. The 53′ length is now, the new the standard length.

Please be sure to read OPNBar Extended Instructions & Precautions

Here are some likely reasons a Drayage Container door will not open or close. Our hand leverage tool / shipping container door extension handle helps to address these issues.

• Rust and Corrosion: The hinge pins and blade are seized due to corrosion.  As shipping containers navigate through diverse weather conditions and environments over time, they become susceptible to rust and corrosion. These corrosive agents can target the locking mechanisms and hinges, ultimately impeding the smooth operation of the container's doors. This accumulation of rust and corrosion introduces a layer of complexity to unlocking and opening the container.
• Maintenance Neglect: Regular maintenance is pivotal to sustaining the functionality of shipping containers. The absence of consistent upkeep can lead to complications with the locking mechanisms, hinges, and seals. Without proper lubrication and care, these components might stiffen or become challenging to manipulate, thereby escalating the difficulty of opening the container.
• Physical Impact: The nature of shipping exposes containers to a barrage of wear and tear, stemming from transportation and handling activities. Consequently, the containers might acquire dents, twists, or misalignments. These physical distortions can hinder the proper alignment of the doors, rendering the opening process arduous.
• Uneven Placement: Placing a shipping container on uneven ground can disrupt its frame's equilibrium. This misalignment can extend to the doors, making them difficult to open or close. The uneven stance of the container introduces an extra layer of complexity when trying to access its interior.  Doors and lock rods may warp or the container frame is racked so that the door gear will not operate correctly. This may be caused by cargo shifting during transit. Look at the container to make sure that the doors are aligned and level, both top, and bottom.
• Temperature Influences: Drastic temperature variations encountered during transportation can trigger material expansion and contraction. This phenomenon reverberates through the locking mechanisms and hinges, potentially impairing their normal operation. The impact of temperature fluctuations compounds the challenges associated with opening the container.  Water has become trapped between frozen shipping container doors, particularly relevant to refrigerated cargoes, or containers with moisture-releasing cargoes in cold weather.
• Inadequate Tools: The task of opening a shipping container may necessitate specialized tools such as heavy-duty bolt cutters or unique locking mechanism tools. In the absence of these tools, the process can become considerably more demanding.
• Sealing Complexity: Some shipping containers employ adhesive materials or seals to ensure the contents remain shielded from environmental elements. Over time, these seals can harden and resist breaking. Consequently, accessing the container requires overcoming this intricate sealing mechanism. 
• The door gasket has been damaged and is preventing opening. Door gaskets are designed to present two or more fins against the structure or adjacent door. These are generally flexible but when the gasket is damaged, they may become hard or blocked thus jamming the door closed, or preventing it from being closed. 
• Security Enhancements: Certain shipping containers incorporate robust security features to discourage unauthorized access and potential theft. Although these features are indispensable for safeguarding the contents, they can inadvertently increase the intricacy of opening the container.
• The Covid economy had also released many shipping containers in the world which are now often reused and the issue of hard-to-open/close used shipping containers is now a more common issue than ever.
