1.1.3 Dual lane axles low bed trailers

Most lowbed trailers are dual line axles low bed trailers, and usually the ramps are at the rearwhile the detachable lowbed trailer is loaded at the front.

1.1.4 Extendable low bed trailer

Extendable lowbed trailer is often used to transport cargo with different lengths moreconveniently.

1.1.5 modular trailer

Modular trailer, also called hydraulic modular trailer, or SPMT for short, is particularly suitablefor the overall transport of drilling platforms, offshore modules, modular plants (petrochemicalsmelting, etc.), power station construction, ro-ro loading onto and off ships, chemical. lt is alarge work piece logistics transport equipment with driving system, helpful for some oversizedand extra-long goods that cannot be disassembled for transport.

1.1 what are the different types of flatbed trailers

Flatbed semi trailer is one of the commonest means of transportation, which can be used totransport containers, as well as bulk goods. Sometimes, flatbed semi trailer can be used as sidewall trailer, fence trailer, a double flatbed trailer.

1.1.1 flatbed semi trailer

Flatbed trailer is available in 20ft, 40ft, 45ft, and 2/3/4 axles. Different configurations dependon the cargo transported (3/4 axle and different type of flatbed trailer)

1.1.2 side wall trailer

Sidewall trailer is a flatbed trailer surrounded by additional baffles. The application is basicallythe same as flatbed semi trailer, drop side trailer can be used to transport some slightly highercargo.

1.1.5 Flatbed trailer with headboard

Flatbed trailer with frontborad is designed to carry and heavy items. lt has a board in the frontwhich can protece the tractor in case of emergency braking. Flatbed trailer with front board istypically used to transport large cargo, such as: construction materials and bulk cargo. it's oftenused in the construction industry.

Different of High bed trailer vs low bed trailer

The difference between High bed trailer and low bed trailer mainly lies in the working platformand purpose. High bed trailer is also called flatbed trailer, flatbed truck trailer. its platformheight is 1500mm, while the lowbed trailer's platform height is between 100-1200mm. in termsof purpose, the high bed trailer is mainly used to transport cargo, while the lowbed trailer ismainly used to transport construction machinery. Common high bed trailer has 20ft, 3 axle 40ft45ft, low bed trailer has 3 axle, 4 axle, 5 axle, 6 axle, 50ton, 60 ton, 80 ton, The maximum loadis 200 ton.

2. History

Lowbed trailer

The lowbed trailer was invented in 1920, mainly using riveted gooseneck and solid rubber tires.but the lowbed trailer could only be loaded from the rear. in 1950, the lowbed trailer wasimproved, with higher loading capacity and easier loading of equipment.

Detachable lowbed trailer was invented in 1958, referred to as RGN. lt can be loaded from thefront. Ramp is not necessary and loading work is more convenient.

3.Applications

What does lowboy trailer used for?Lowbed trailer is mainly used for transporting excavators, harvesters, loaders, forklifts andother heavy equipment.

What does flatbed semi trailer used for?

Flatbed semi trailer is mainly used for transporting containers, construction materials, bulkgoods, lumber, steel coils, etc., including any cargo that does not fit in an enclosed trailer.

4.Feature

Flatbed semi trailer

1. Easier loading and unloading

Flatbed semi trailer is more spacious to operate, so both loading and unloading are moreconvenient. Cargoes can be loaded and unloaded from all sides of flatbed semi trailer, and thecargoes can be packed well to ensure safety.

2. Different sizes for different transportation

Flatbed semi trailer is available to be made longer or shorter according to customer's demandFor example, if transport iron bars, the extended flatbed semi trailer is perfect for this purpose.

3. Transporting heavy materials.

Flatbed trailers is with high carrying capacity. Flatbed trailers can haul any cargo, from tractorsmilitary equipment, construction materials to containers.

Lowbed trailer

1. Stability

Lowbed trailer is more stable because it has a lower center of gravity, so it is safer in thetransportation 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 forlowbed trailer, generally workers drive the equipment through the track directly onto the lowbedtrailer.

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. lf it is significantly lowerthan 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. lf it is below thestandard line, the master cylinder or cylinder cup may be damaged. When the engine is runningit 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 upperand lower limits, and electrolyte or distilled water should be added to the high voltage lineimmediately 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. lf the brake fluid is near orbelow the lower limit, it means the system may be leaking or the brake shoes are excessivelyworn. 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 themaintenance 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 ABSsystem, through the analysis of the signal sent by the sensor, gives reasonable orders to thebraking system, ensuring the stability and safety of the trailer in the emergency braking. Aftelthe emergency braking, when the wheels of the semi-trailer are clamping, the ABS system wilstart the pressure regulating valve to control the pressure in each brake hose and intelligentlyadjust the internal pressure according to the force of the body. So the wheels, tires and roadare in the balance of force, preventing the body from rolling over and avoiding accidents.

7. Which is the best choice

We need to know the local laws, weight limits, height limits and the cargo that we need totransport. Then we can choose between low bed trailers and flatbed trailers.

Summrise:

Different between lowbed trailer and flatbed trailer is end. Flatbed trailers and lowbed trailershave many similarities and differences, mainly in the goods to be transported and classificationWe can choose according to the cargo what we need to transport, local height, and weightlimits.
