2. History

Lowbed trailer

The lowbed trailer was invented in , mainly using riveted gooseneck and solid rubber tires, but the lowbed trailer could only be loaded from the rear. In , the lowbed trailer was improved, with higher loading capacity and easier loading of equipment.

Detachable lowbed trailer was invented in , referred to as RGN. It can be loaded from the front. Ramp is not necessary and loading work is more convenient.

Flatbed semi trailer

The first flatbed semi trailer was born in , with a relatively simple structure and poor loading capacity. As the flatbed semi trailer was constantly updated, the configuration was upgraded and the loading capacity became more and more powerful.

3. Applications

What does lowboy trailer used for?

Lowbed trailer is mainly used for transporting excavators, harvesters, loaders, forklifts and other heavy equipment.

What does flatbed semi trailer used for?

Questions You Should Know about modular low bed semi trailers

With competitive price and timely delivery, Haiheyuan sincerely hope to be your supplier and partner.

Lowbed trailer is more stable because it has a lower center of gravity, so it is safer in the transportation process.

2. Large space

Lowbed trailer has more space and can be used to load cargo with heavier weight.

3. Suitable for countries with height limit

Lowbed trailer is lower, so it is suitable for some countries with strict height limit.

5. How to load and unload semi trailer

For flatbed semi trailer, generally forklift or frontal crane is needed to load or unload, while for lowbed trailer, generally workers drive the equipment through the track directly onto the lowbed trailer.

6. Maintenance

The maintenance of flatbed trailer and lowbed trailer is same.

1. Check the tires.

The tire pressure should be checked monthly at room temperature. If it is significantly lower than normal, it should be added immediately.

2. Check the oil level of the clutch master cylinder.

When the clutch oil level is between the high and low levels, it is normal. If it is below the standard line, the master cylinder or cylinder cup may be damaged. When the engine is running, it will be difficult or impossible to shift gears. Please go to the nearest service station immediately.

3. Maintenance and inspection of semi-trailer battery

Check whether the semi-trailer battery is firmly fixed. Electrolyte should be between the upper and lower limits, and electrolyte or distilled water should be added to the high voltage line immediately if it is very close to the offline. Keep the positive and negative cables of the semi-trailer battery in good contact, and keep the semi-trailer battery clean and dry.

4. Check the brake fluid level.

If the brake fluid is also between the high and low levels, it is normal. If the brake fluid is near or below the lower limit, it means the system may be leaking or the brake shoes are excessively worn. You should have this repaired immediately at a service station.

5. Check the ABS brake valve

If you have an ABS brake valve installed remember to check it frequently. Follow the maintenance instructions and the principle of the ABS brake valve.

How to use the ABS system

Whether air pressure control or hydraulic control method is adopted, the controller in the ABS system, through the analysis of the signal sent by the sensor, gives reasonable orders to the braking system, ensuring the stability and safety of the trailer in the emergency braking. After the emergency braking, when the wheels of the semi-trailer are clamping, the ABS system will start the pressure regulating valve to control the pressure in each brake hose and intelligently adjust the internal pressure according to the force of the body. So the wheels, tires and road are in the balance of force, preventing the body from rolling over and avoiding accidents.

What is lowbed

Lowbed trailer usually adopt an open beam (or sound type) frame. The front section of the whole structure likes swan-neck (swan-neck front section of the traction pin is connected with the traction saddle on the traction car, and the swan-neck rear end is associated with the semi-trailer frame), and the middle section is the cargo platform (the lowest part of the frame), and the back end is the wheel frame (including wheels).

Difference between low bed and flatbed trailer

The purpose of flatbed trailers and low bed trailers are very different. The flatbed trailer is mainly used to transport cargo, while the low bed trailer is mainly used to transport construction machinery. Meanwhile, in terms of design, the flat of flatbed trailer has the same height, while the flat of low bed trailer has a lower middle, and its flat design is generally high and low.

Why Required lowbed trailer?

1. Heavy Machinery and Equipment: Lowbed trailers are designed to carry heavy machinery and equipment, such as construction machinery, cranes, excavators, bulldozers, and industrial components. These items are often too large, heavy, or cumbersome to be transported on regular trucks.
2. Oversized Loads: When transporting oversized cargo like large tanks, turbines, or wind turbine blades, lowbed trailers are necessary because they offer a lower deck height, which allows the cargo to fit within height restrictions and pass under bridges or overpasses.
3. Tall Cargo: Some cargo items may have considerable height, making it impractical or impossible to fit them into standard trailers. Lowbed trailers with their lower deck height can accommodate taller cargo safely.
4. Stability and Safety: Lowbed trailers have a lower center of gravity compared to standard trailers, providing enhanced stability during transportation. This stability is crucial when carrying heavy and high-value loads over long distances.
5. Bridge and Road Weight Limits: Different countries and regions have weight restrictions for vehicles traveling on their roads and bridges. Lowbed trailers distribute the weight of the cargo more evenly, making it possible to transport heavier loads without exceeding legal weight limits.
6. Construction and Infrastructure Projects: Lowbed trailers are commonly used in construction and infrastructure projects to transport heavy construction equipment and materials to remote or challenging job sites.
7. Energy Sector: In the energy sector, lowbed trailers are often employed to transport components for power plants, oil rigs, and other large-scale energy projects.
8. Mining and Agriculture: The mining and agriculture industries use lowbed trailers to transport heavy machinery, vehicles, and equipment required for their operations.
