Key Considerations:
- Length Options: Flatbed trailers are available in standard lengths such as 20ft, 40ft, 48ft, and 53ft, but these can be customized to fit specific needs.
- Axle Configurations: Trailers may have 2, 3, 4, or 5 axles, and the number of axles determines the load capacity and stability of the trailer.
- Weight Capacity: Weight capacity varies depending on the number of axles and overall design. Heavier-duty flatbed trailers can carry up to 160 tons of load, making them suitable for oversized loads or machinery.
- Wheel Configuration: Larger trailers typically come with multiple wheels for enhanced stability and weight distribution. For example, an 18-wheeler flatbed trailer has 18 wheels to support larger loads.
- Suspension Type: Air suspension is often preferred for carrying sensitive cargo as it provides a smoother ride. However, leaf spring suspension is more common for heavy-duty trailers due to its durability and load-bearing capacity.
- Ramp Types: Depending on the trailer type, ramps can be manual, hydraulic, or foldable, enabling easy loading and unloading of equipment.
Different Flatbed Semi Trailers
3/4/5 Axle Flatbed Trailers
3, 4, and 5 axle flatbed trailers feature a flat, open platform without sides or a roof, making them ideal for carrying bulky or irregularly shaped cargo.
The number of axles increases the trailer’s weight-bearing capacity, providing stability and enhancing the overall strength, transporting heavy loads of up to 80 tons or more.
20, 40, 48, and 53 ft Flatbed Trailers
Flatbed trailers come in a variety of sizes, and the 20 ft, 40 ft, 48 ft, and 53 ft versions are among the most commonly used.
The size of the flatbed trailer plays an important role in determining its application, the choice of flatbed size often depends on the type of cargo being transported, local regulations, and load requirements.
10-Wheeler and 18-Wheeler Flatbed Trailers
10-wheelers and 18-wheelers are two common configurations used in heavy-duty transportation.
The number of wheels on a flatbed trailer is an indicator of the axle configuration and its weight-carrying capacity.
Fixed & Detachable Gooseneck Flatbed Trailers
Fixed Gooseneck flatbed trailer is characterized by a permanently attached gooseneck to the trailer’s frame. The gooseneck is the front portion of the trailer that connects to the towing vehicle via the hitch.
Since the gooseneck is fixed and does not detach like a lowboy, a ramp system is often necessary to create an appropriate angle for loading
Detachable Gooseneck (or Lowboy) flatbed trailer features a gooseneck that can be removed from the trailer’s frame. This allows for a more versatile design where the neck can be detached, creating a ramp for loading/unloading heavy machinery and equipment.
The detachable gooseneck is often used for transporting heavy and oversized loads that need to be loaded from the ground up. It requires a igher maintenance due to detachable parts.
