Types of Lowbed Trailers

A lowbed trailer, also known as a low loader, is an engineering vehicle that is mostly used in transporting heavy equipment. These trailers are designed with a low height, making it easy to load and offload the equipment. Lowbed trailers are primarily divided into two types:

• Fixed-axle lowbed trailers

  The fixed-axle lowbed trailers have an axle that is fixed under the trailer. This means that the axle doesn't move whenever the trailer is turning. Due to this feature, the lowbed trailer has a higher weight capacity. The fixed axle lowbed trailers are mostly used in carrying heavy construction equipment.

• Detachable-axle lowbed trailers

  The detachable-axle lowbed trailers, also known as the extendable lowbed trailers, have an axle that is attached to the trailer using a pin or hinge. This means that the axle can be detached from the trailer. The detachable lowbed trailers are designed with a lower loading height, making it easy to load and offload the equipment. Due to this feature, the detachable lowbed trailers are mostly used in transporting tall and heavy machinery.

Lowbed trailers also come in different sizes and designs to suit various transportation needs. Here are some common types of lowbed trailers:

• Gooseneck Lowbed Trailers

  The gooseneck lowbed trailers are designed with a neck that extends in front of the trailer. This neck usually connects to the towing vehicle. The gooseneck trailers allow the operator to drive the trailer rather than tow it behind the vehicle. The gooseneck lowbed trailers are available in both fixed-axle and detachable-axle designs.

• Fifth Wheel Lowbed Trailers

  The fifth-wheel lowbed trailers are designed to be towed behind a truck that is equipped with a fifth-wheel coupling. These trailers are mostly used in transporting heavy loads on highways and roads.

• Hydraulic Steering Lowbed Trailers

  The hydraulic steering lowbed trailers are designed with a hydraulic steering system. This system allows the operator to control the steering of the trailer using hydraulics. The hydraulic steering lowbed trailers are mostly used in transporting heavy equipment in urban areas.

• Multi-Axle Lowbed Trailers

  The multi-axle lowbed trailers are designed with multiple axles. This feature allows the trailer to distribute the heavy load evenly, reducing wear and tear. The multi-axle lowbed trailers are commonly used in transporting large and heavy industrial equipment.

• Tire Maintenance

  The lowbed trailer tire plays an important role in the trailer safety and efficiency. Therefore, it is necessary to maintain the trailer tire regularly. This includes checking the tire pressure, tread depth, and sidewall condition. Ensure that the tire pressure meets the manufacturer's specification. Replace the tire timely when the tread depth reaches the replacement standard.

• Lubrication

  Lowbed trailers have many moving parts that need regular lubrication. This reduces the friction and wear between the parts, extending their service life. Lowbed trailer operators can choose the appropriate lubricant according to the manufacturer's recommendations and the environmental conditions.

• Brake Maintenance

  Lowbed trailers usually transport heavy loads, so they need effective brake systems. Regular inspection and maintenance of the trailer brake systems are necessary to ensure safety under all load conditions. This involves checking brake pads, calipers, and brake fluids. Replace the brake pads according to the manufacturer's suggestions and the actual use conditions to maintain optimal braking performance.

• Load Distribution

  Lowbed trailer loading is a key factor affecting the trailer performance and safety. Unreasonable loading can lead to lowbed trailer instability, tire wear, and increased stress on the frame and axle. Therefore, it is important to ensure that the load is evenly distributed according to the manufacturer's recommendations and the trailer design.

How to Choose Lowbed Trailer

A lowbed trailer is an essential piece of equipment for industries that require the transportation of heavy and oversized loads. Choosing the right lowbed trailer for specific needs is not as easy as it sounds. Here are some of the factors that need to be considered;

Firstly, it is important to determine the type of load that needs to be transported. Understand the weight and dimensions of the load. This is important as it helps buyers avoid choosing a trailer that is either overloaded or underloaded. The lowbed trailer also has specific features that accommodate different types of loads.

Secondly, the buyer should consider the trailer capacity. As mentioned above, the lowbed trailer capacity should match the load that is being transported. This means that the trailer capacity should be greater than the maximum load to be transported. The buyer should also consider the distribution of the load to avoid compromising the trailer's stability.

The design of the lowbed trailer is also a crucial factor to consider. This is because different designs suit different applications. Buyers should choose the design that best fits their needs. For instance, they can choose a model with a hydraulic ramp for easy loading and unloading.

Another important factor to consider when choosing a lowbed trailer is the suspension system. Lowbed trailers are designed with oversized and heavy loads in mind. This means that they are fitted with a suspension system that offers stability and a smooth ride even when transporting such loads.

Additionally, buyers should consider the material that makes the lowbed trailer. Different trailers are constructed from various materials. Each has its advantages. For example, a trailer made out of steel is known for its strength and durability.

Finally, the buyer should consider the features of the lowbed trailer. This includes things like loading capacity, length, and width. They should also consider additional features like hydraulic ramps, winches, and loading bars.

By considering all these factors, buyers can choose the right lowbed trailer for their transportation needs.

How to DIY and Replace Lowbed Trailers

Here are some steps for DIY replacement of different parts of the lowbed trailer.

• Replacing the Tire

  To replace the tire of a lowbed trailer, start by ensuring the trailer is on a stable, level surface. Engage the parking brakes and place wheel chocks on the tires that won't be replaced. Then, loosen the lug nuts slightly using a lug wrench. Jack up the trailer until the tire being replaced is off the ground. Completely remove the lug nuts and take out the old tire. Mount the new tire onto the wheel hub and hand-tighten the lug nuts. Lower the trailer until the tire is level with the ground. Torque the lug nuts in a crisscross pattern to ensure even pressure and remove the jack and wheel chocks.

• Replacing the Brake Pads

  To replace the brake pads, start by ensuring the trailer is on a stable, level surface. Engage the parking brakes and place wheel chocks on the tires. Remove the tire to access the brake pads. Depending on the design, either unbolt or slide the brake caliper to reach the brake pads. Remove the old brake pads from the caliper bracket. Install the new brake pads into the caliper bracket and reattach the caliper. Reinstall the tire and lower the trailer.

• Replacing the Suspension Bushes

  To replace the suspension bushes, start by ensuring the trailer is on a stable, level surface. Engage the parking brakes and place wheel chocks on the tires. Then, lift the trailer with a jack and secure it with jack stands. Locate the suspension bushes on the trailer's axles. Depending on the design, unbolt or press out the old bushes. Position the new bushes and press or bolt them in place. Remove the jack stands and lower the trailer.
