Lowbed Trailer are usually used to transport a variety of machinery and equipment, heavy equipment, highway construction equipment, large tank body, power station equipment, and various excavators, and are used to transport heavy vehicles (such as tractors, coaches, Subway truck head, etc.), rail vehicles, mining machinery, forestry machinery, construction machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy-duty cargo.
The lower the platform height of the heavy load trailers, the better the stability and safety. Our low loader has a large carrying capacity when transporting extra high and medium cargo. TITAN semi low bed trailer height from ground is usually 1300mm. If you have special needs, TITAN can also customize it for you.
There are many structures and styles of low deck trailer. Below we introduce the two most common styles.
Low bed trailer usually use a high-low frame, that is, the front section of the frame is a gooseneck (the traction pin at the front section of the gooseneck is connected to the traction saddle on the tractor, and the back end of the gooseneck is connected to the low bed semi trailer frame).The middle part is the cargo platform (the lowest part of the frame).
This structure can transport a variety of heavy equipment, can also transport other general cargo, can also transport 40-foot containers, 20-foot containers. The export volume of machine carriers of this structural style to Africa is the largest. Low loader car carrier for sale NZ India price.
Another structure commonly used in low loader for sale: a concave beam frame. The front section of the frame is gooseneck (the traction pin at the front section of the gooseneck is connected to the traction saddle on the tractor, and the back end of the goose neck is connected to the heavy duty equipment trailer frame), the semi low bed trailer middle section is the cargo platform (the lowest part of the frame), and the rear end is Wheel frame (including wheels).
When loading mechanical equipment on a low deck trailer, it is usually loaded from the rear of the heavy load trailers, that is, by moving the mechanical equipment from the rear wheel frame or removing the wheels, and then fixing the mechanical equipment to the low bed loader.

Low bed trailers can transport heavy cargo in different industries. Here are the most common uses of heavy-duty trailers.
Heavy vehicles: Vehicle manufacturers use low bed trailers to transport heavy vehicles from one showroom to another. The transporters are used to move the vehicles from the port to showrooms and sometimes to clients.
Construction: semi low bed trailers are used in the construction industry as well. Heavy duty vehicles are commonly used in the construction of roads and bridges.
Some construction equipment and blocks cannot be transported with normal semi-trailers. Low bed trailers are used to transport concrete blocks to the construction sites.
Mining machinery: Mining requires heavy machinery for drilling and transporting materials including crude oil and minerals. The machinery is assembled offsite and then transported to the mining sites using low bed trailers.
The semi low bed trailer is preferred because of the structure of mining machinery. Mining equipment is perhaps the heaviest cargo that machinery manufacturers transport on the road.
Windmill components: The components of windmills are usually assembled in a factory and then transported to their sites. Similar to other heavy cargo, the components are wide and heavy.
The components cannot fit on a closed trailer because of their design and structure. Lowboy trailers are an efficient way of transport these components to their site.
1. Low loader trailer have flatbed, concave beam and tire exposed structures, and the longitudinal beams are straight or gooseneck. The frame is stepped, and the cross section of the longitudinal beam is I-shaped, which has the characteristics of high rigidity and high strength.
2. The main plane of the frame and cargo platform is low, which ensures the stability of transportation, and is suitable for carrying all kinds of construction machinery, large equipment and steel.
3. It adopts three-axis balanced, two-axis balanced or rigid suspension, with mass balance blocks installed between the front and rear leaf springs, which can change the deflection of the front and rear leaf springs by the same amount and balance the forces on the front and rear axles;
4. The low bed truck series products are suitable for a variety of mechanical equipment, large objects, road construction equipment, large tanks, power station equipment and machinery. They are widely used, efficient and fast. The whole heavy load trailer adopts advanced computer-aided design software, which is optimized for flexible and diverse design. The load-bearing surface of the frame is designed according to user requirements to meet the transportation of various special goods.
5. Trailers are divided into semi-trailers and full-trailers. The semi-trailer axle is placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and is equipped with a coupling device that can transmit horizontal or vertical force to the tractor. The front part of the carriage rests on the pallet of the tractor. low loader trailers are generally under 13 meters. The load of the trailer is fully borne by itself, and it is connected with the locomotive only by hooks. The locomotive only provides power to help the lowbed full trailer overcome the frictional resistance of the road. It can stand upright on its own tires. Generally around 6.5 meters.

The ordinary low bed trailers, RGN trailers, and low loaders have their advantages and disadvantages. We can provide you with a suitable heavy duty excavator trailer according to your needs.
Cargo dimension: It is important to consider the dimensions of your cargo when choosing a trailer model. Different axle configurations carry different cargo equipment. For your trailer to be more efficient, the weight should be evenly supported and distributed over the trailer.
If the height of your cargo is too high, choose a low loader, an RGN trailer, or a folding gooseneck trailers. The models allow you to lower the rear part and reduce the total height of the cargo.
Therefore, you should know how your cargo equipment will be loaded on your trailer and then choose the design that matches it.
Price: The prices of low bed trailers vary with their load capacities and performance.
If you are looking for a trailer to transport heavy cargo at the least cost possible, the ordinary low bed trailers are your best choice.
Cargo weight: The right model will depend on the maximum weight of your cargo. If you intend to transport more than 70 tons, consider buying low loaders, RGN trailers. Lowering the center of a heavy load increases its stability.
Maintenance costs: The buying price is not the only cost you will incur on your heavy load trailer. You have to service the trailer regularly to maintain its optimal performance.
Manufacture Quality: Check on the quality of welding done on the trailer. Good quality welding can guarantee strength to your low bed trailer structure. The welding joints contribute a lot to the fatigue resistance of your low bed trailer.
The sharp geometry created by welding joints largely reduces the fatigue resistance of that section when compared to the base material.
There are residual stresses that get introduced during welding as a result of the heat used during the process. However, there is a way that these stresses can be minimized. You can tell by observing the quality of weld on the trailer framework.
Your focus on fatigue resistance should not only be based on the micro-structures of the base material, its hardness and the heat affected zones.

Semi trailer theory research shows that the passability of a low bed truck refers to the ability of a car to pass through various road conditions at a sufficiently high average speed under a certain load.
There are many influencing factors for vehicle passability. From the perspective of giving full play to the power of the drop deck trailer, driving speed, car wheels, differentials, driving methods, etc. have an impact on passability; from the perspective of the vehicle technical structure, the minimum ground clearance of the step deck trailer, Longitudinal passing radius, lateral passing radius, minimum turning diameter, etc., reflect the passing capacity of the vehicle; from the perspective of highway technical indicators, the carrying capacity, slope, bend radius and clearance of the highway limit the passing of the vehicle.
Heavy-duty low loader trailer transportation due to their ultra-long, ultra-wide, and ultra-high characteristics, determine that they are different from ordinary vehicles during transportation, especially in terms of passability, the strength, clearance, and technology of roads, bridges, and tunnels along the way. The conditions have special requirements.
Engineering practice shows that during heavy transportation, air obstacles, road or bridge cargo restrictions, obstructions on roads and facilities above, etc. often impede the passage of transportation. According to the characteristics of heavy transportation work and transportation requirements, it can be summed up. The passability of the vehicle includes the following aspects.
Road load capacity
The load tonnage of large parts transportation is generally large, and the roads and bridges that need to pass through the ground and have large loads should have a large area with sufficient load capacity. Therefore, the roads and bridges need to be analyzed and checked. If it does not meet the strength requirements, it will inevitably cause the vehicle-cargo system to be unstable and cause a safety accident.
Horizontal and longitudinal capacity
The cross slope and longitudinal slope of the highway have a great influence on the stress system of transportation vehicles and cargoes. From the previous vehicle stability analysis, it can be seen that if the cargo has a certain strapping method, if its maximum lateral and longitudinal tilt angle exceeds the allowable The angle will destroy the stability of the transportation vehicle, which means that the transportation vehicle cannot pass through such a steep road.

Curve passing ability
Usually highways are designed according to highway technical standards, but because the large-sized transportation low loader trailer for sale are different from the ordinary design vehicles based on highways in terms of both the shape of the equipment trailer and its turning ability, it is necessary to check the curve data of the highway along the way to Determine whether the vehicle can pass safely.
Due to the ultra-high and ultra-wide width of large objects, the clearance size of roads, bridges, tunnels and buildings on the road must be passed to ensure the safe passage of transportation vehicles.
