Are you considering investing in a deckover dump trailer? With fold-down sides and the capacity to haul large loads, a deckover dump trailer is an essential tool for any contractor. One of the best on the market is the Iron Bull Deckover Dump Trailer: it's strong and sturdy, built from heavy-duty steel, and designed to last for years. Let's explore why you need one!

What is a deckover dump trailer?

A deckover dump trailer is a type of trailer that is designed to haul and dump large loads. Unlike standard trailers, it features fold-down sides which make it easy to load and unload materials. It's called a "deckover" trailer because the flooring is flush with the top of the wheel wells, giving it a flat deck. 

Key Features of Deckover Dump Trailers

Deckover dump trailers are heavy-duty trailers designed for hauling and dumping large loads of materials. They are commonly used in construction, landscaping, and other industries that require heavy hauling. Here are some key features of deckover dump trailers:

Deckover Design

Deckover dump trailers have a deck that sits on top of the trailer's frame, providing a flat and wide surface for loading and unloading materials. The deck extends beyond the wheels, allowing for maximum payload capacity.

Dumping Mechanism

These trailers are equipped with a hydraulic dumping mechanism that allows the entire bed to be raised and tilted, enabling easy and controlled unloading of materials. The dumping mechanism is typically operated by a hydraulic cylinder, which is powered by an electric or hydraulic system.

High Payload Capacity

Deckover dump trailers are built to handle heavy loads. They have a high payload capacity, which means they can carry and transport large volumes of materials, such as gravel, soil, sand, rocks, or debris.

Reinforced Construction

To withstand the heavy loads and harsh working conditions, deckover dump trailers are constructed with heavy-duty materials. The frame is reinforced and made from strong steel, providing structural integrity and durability.

Side Walls and Tailgate

These trailers feature sturdy side walls that contain the load during transport. The side walls are typically removable or foldable, allowing for easy loading and unloading of materials. The trailers also have a hinged tailgate at the rear, which can be opened to facilitate dumping.

Tandem Axles

Most deckover dump trailers come with tandem axles, which means they have two axles placed close together to distribute the weight evenly. Tandem axles provide better stability and weight-bearing capacity, making them suitable for heavy loads.

Brake System

Deckover dump trailers are equipped with a reliable brake system to ensure safe and controlled stopping. They often have electric brakes or hydraulic surge brakes, depending on the specific model and regulations in the region where they are used.

Lighting and Safety Features

These trailers are equipped with lighting systems, including tail lights, brake lights, and turn signals, to ensure visibility and compliance with road safety regulations. Some models may also have additional safety features such as reflectors, breakaway kits, and safety chains.


Deckover dump trailers are designed to be versatile and adaptable to different hauling needs. They can be used for transporting various types of materials and equipment, and some models may offer customization options such as additional tie-down points, toolboxes, or ramps for loading equipment.

It's important to note that specific features may vary depending on the manufacturer and model of the deckover dump trailer. It's recommended to consult the product specifications or contact the manufacturer directly for detailed information about a specific trailer model.

How does a deckover dump trailer work?

A deckover dump trailer operates through a combination of hydraulic and mechanical systems. Here's how it generally works:

  1. Loading: To load materials into the deckover dump trailer, you typically drive or manually load them onto the flat deck. The deck is designed to accommodate heavy loads and is usually reinforced to handle the weight.

  2. Securing the Load: Once the materials are loaded onto the trailer, they can be secured using tie-downs or straps to prevent movement during transportation.

  3. Raising the Bed: When it's time to unload the materials, the trailer's hydraulic system is activated. The hydraulic system is typically powered by an electric or hydraulic pump.

  4. Hydraulic Cylinder: The hydraulic system activates a hydraulic cylinder, which is usually located beneath the bed of the trailer. The cylinder extends or retracts, depending on the direction of hydraulic pressure.

  5. Tipping the Bed: As the hydraulic cylinder extends, it lifts the bed of the trailer, tilting it towards the rear. This tilting action is what allows the materials to be unloaded from the trailer.

  6. Unloading the Materials: With the bed tilted, gravity causes the materials to slide or fall out of the trailer. The raised position of the bed creates a slope that facilitates the controlled and efficient unloading of the materials.

  7. Lowering the Bed: After the materials are fully unloaded, the hydraulic system is reversed, and the hydraulic cylinder retracts. This lowers the bed of the trailer back to its original position.

  8. Securing the Bed: Once the bed is lowered, it is securely locked into place to ensure stability and safety during transportation.

It's important to note that the exact operation of a deckover dump trailer may vary slightly depending on the specific model and manufacturer.

What are the pros and cons of a deckover dump trailer?

Deckover dump trailers offer several advantages and have some considerations to keep in mind. Here are the pros and cons of using a deckover dump trailer:


  • High Payload Capacity: Deckover dump trailers are designed to handle heavy loads, making them suitable for transporting large volumes of materials. Their high payload capacity allows for efficient hauling and increased productivity.

  • Versatility: These trailers are versatile and can be used for various purposes. They can transport different types of materials, equipment, and machinery, making them useful in construction, landscaping, agricultural, and other industries.

  • Easy Loading and Unloading: The dump feature of these trailers simplifies the process of loading and unloading materials. The hydraulic dumping mechanism allows for controlled and efficient unloading, saving time and effort.

  • Accessibility: The deckover design of these trailers provides a flat and wide surface for loading and unloading materials. This design allows for easier access to the cargo and eliminates the need for fender wells, which can obstruct loading and reduce usable space.

  • Stability and Weight Distribution: Deckover dump trailers often come with tandem axles, which provide better stability and weight distribution. The axles are positioned close together, allowing for more even weight distribution and enhanced towing stability.

  • Durability: Deckover dump trailers are typically constructed with heavy-duty materials such as steel, making them durable and capable of withstanding demanding work conditions. This durability ensures longevity and reduces the need for frequent repairs or replacements.


  • Height and Size: The deckover design, while advantageous in terms of loading capacity, also means that these trailers have a higher profile. The increased height can make them less maneuverable in certain situations and may require additional caution while driving under low-clearance obstacles.

  • Increased Weight: Due to their construction and high payload capacity, deckover dump trailers tend to be heavier than other trailer types. This additional weight can affect fuel efficiency and require a more robust towing vehicle to handle the load.

  • Cost: Deckover dump trailers typically come with a higher price tag compared to other types of trailers. The heavy-duty construction and hydraulic dumping mechanism contribute to the increased cost.

  • Maintenance: The hydraulic systems and other mechanical components of deckover dump trailers require regular maintenance to ensure proper functionality. This may include hydraulic fluid checks, lubrication, and periodic inspections, which can add to the overall maintenance costs.

  • Limited Maneuverability: The larger size and higher weight of deckover dump trailers can limit maneuverability, especially in tight spaces or crowded job sites. It's important to consider the available space for maneuvering and parking when using these trailers.
