Lowbed trailers for the transport of higher loads
Lowbed Trailers for the Transport of Higher Loads
Lowbed trailers excel in transporting heavy and oversized loads due to their low center of gravity and enhanced stability. They are specifically designed to handle diverse transport challenges. When comparing lowbed trailers to flatbed trailers, it is crucial to consider the load requirements, operational terrain, and local regulations to make an informed choice.
Lowbed Trailer Vs Flatbed Semi Trailer
This article examines the distinctions between lowbed trailers and flatbed trailers, encompassing their definitions, types, histories, applications, features, and maintenance. By understanding these differences, you can make a more informed decision on which type of trailer best suits your transport needs.
1. Definition
1.1 Low Bed Trailer Types
There are several variants of lowbed trailers, including hydraulic low bed trailers, detachable lowbed trailers, dual-line axle lowbed trailers, extendable lowbed trailers, and modular trailers. These trailers are primarily used to transport non-detachable objects like excavators, harvesters, loaders, forklifts, and other specialized vehicles that cannot move independently. Typically, lowbed trailers are equipped with ramps to facilitate the loading of such equipment.
1.1.1 Ordinary Lowbed Trailer
Ordinary lowbed trailers can handle loads ranging from 20 tons to 200 tons and generally feature 2 to 10 axles.
1.1.2 Extendable Low Bed Trailer
The most common extendable lowbed trailer is a 3-axle, 60-ton unit. Options range up to 5 axles with a maximum load capacity of 120 tons.
1.1.3 Dual Lane Axles Low Bed Trailers
Most lowbed trailers are dual-line axle models, with ramps typically located at the rear. Detachable lowbed trailers, however, are loaded from the front.
1.1.4 Extendable Low Bed Trailer
These trailers are ideal for transporting cargo of varying lengths more efficiently.
1.1.5 Modular Trailer
Also known as hydraulic modular trailers or SPMTs, they are suited for the transport of drilling platforms, offshore modules, petrochemical plants, power stations, and other large logistics transport equipment.
1.2 Types of Flatbed Trailers
Flatbed semi-trailers are widely used for transporting containers and bulk goods and can be configured as sidewall trailers, fence trailers, or double flatbed trailers.
1.2.1 Flatbed Semi Trailer
Available in sizes of 20ft, 40ft, 45ft, with 2 to 4 axles depending on the type of cargo.
1.2.2 Side Wall Trailer
This type of flatbed trailer is bordered by additional baffles, making it useful for transporting slightly taller cargo.
1.2.3 Fence Semi Trailer
Designed primarily for the transport of livestock like cattle and poultry.
1.2.4 Double Flatbed Trailer
This trailer has a triangular front section and two connected flatbeds.
1.2.5 Flatbed Trailer with Headboard
This type includes a front board for carrying heavier items and protecting the tractor during emergency braking, making it useful for transporting construction materials.
Difference Between High Bed and Low Bed Trailers
High bed trailers, or flatbed trailers, typically have a platform height of 1500mm, whereas lowbed trailers range between 100-1200mm. High bed trailers are usually employed for general cargo, while lowbed trailers are specialized for construction machinery.
2. History
Lowbed Trailer
The lowbed trailer was invented in the 1920s, featuring riveted goosenecks and solid rubber tires. By the 1950s, improvements were made to enhance loading capacities and ease of equipment loading. The detachable lowbed trailer, known as RGN, was invented in 1958, allowing front loading without ramps.
Flatbed Semi Trailer
First manufactured in 1914, flatbed semi-trailers have evolved to feature stronger configurations and better loading capacities.
3. Applications
Uses for Lowboy Trailers
Primarily used for transporting heavy equipment like excavators, harvesters, loaders, and forklifts.
Uses for Flatbed Semi Trailers
Ideal for transporting containers, construction materials, bulk goods, lumber, and steel coils.
4. Features
Flatbed Semi Trailer
1. Easier loading and unloading, accessible from all sides, ensuring cargo safety.
2. Customizable sizes for different types of cargo.
3. Capable of transporting heavy materials like tractors, military equipment, and containers.
Lowbed Trailer
1. Stability due to a lower center of gravity.
2. Larger space for heavier loads.
3. Suitable for regions with strict height limits.
5. How to Load and Unload Semi Trailers
Flatbed semi-trailers typically require forklifts or frontal cranes, while lowbed trailers usually allow equipment to be driven directly onto them via ramps.
6. Maintenance
Maintenance for both flatbed and lowbed trailers is similar:
1. Regular tire pressure checks.
2. Clutch master cylinder oil level inspections.
3. Battery maintenance.
4. Brake fluid checks.
5. ABS brake valve inspections.
How to Use the ABS System
The ABS system ensures stability and safety during emergency braking by regulating brake hose pressure and balancing the forces acting on the trailer.
7. Best Choice
Consider local laws, weight, and height limits, and the type of cargo when choosing between low bed and flatbed trailers. For tailored advice based on your specific needs, contact us directly.
Summary: Both lowbed and flatbed trailers serve specific purposes. Choosing the right one depends on the type of cargo, local regulations, and specific transport needs.
What is Lowbed
A lowbed trailer typically features an open beam frame with a swan-neck front section connected to the tractor and a low cargo platform in the middle.
Difference Between Low Bed and Flatbed Trailer
The main difference lies in their usage: flatbed trailers are for general cargo, while low bed trailers are for construction machinery. Their platform heights also differ, with flatbeds being uniformly high and low beds having a lower central section.
