The front section of the frame is a gooseneck (the traction pin in the front section of the gooseneck is connected to the traction saddle on the tractor, and the rear end of the gooseneck is connected to the semi-trailer frame) Cargo platform (the lowest part of the frame), the rear end is the wheel frame (including wheels).

This semi-trailer normally is used to transport large construction machinery,such as excavators, rollers and cranes.

2)Of course, lowboys are also used to transport heavy cargo. Due to the low center of gravity of the trailer, it can transport huge cargo and avoid damage to the cargo. This trailer is designed to solve the overload problem of a large tonnage. Usually ordinary semi-trailers use a structure of two axles and one line, but dolly trailers can have multi-lines, such as 4 axles and 16 tires, and are usually used to transport heavy cargo. Each axle of a dolly trailer loads 50 percent of the weight. Many countries are only allowed to have each axle of a vehicle loading 10 tons.

Our lowboy trailer for sale has a detachable gooseneck design on the front, which avoids overturning the body when transporting heavy equipment and ensures the safety of the vehicle and the driver.

Concave beam type,the plane of the cargo platform is concave and has the lowest load-bearing plane. It is generally suitable for transporting large or ultra-high equipment.

3.CIMC Outlines of Vehicle and Composition

Before production, CIMC technical department must first design and produce drawings according to the needs of the user and the market, so that the technical parameters of the main trailer are matched, and then transferred to the manufacturing department.There are dimensions and specs drawing of different types lowbed semi traielr. You can learn more details in the pictures.

5.Production Process of CIMC Lowbed Semi Trailer

Before production, CIMC technical department must first design and produce drawings according to the needs of the user and the market, so that the technical parameters of the main trailer are matched, and then transferred to the manufacturing department.

1. Stage of cutting steel sheet material

According to the drawings of each part produced by the design department, each part is cut out with a CNC cutting machine, such as beam webs, reinforcement plates, standard small accessories and so on.

2. Opening, calibration beam, through beam

First cut out the web of the beam to cut out U-shaped holes through which the beams can pass, and then fix the welded I-beams in parallel. The result of comparing the beams is very important. If two I-beams have large parallel errors, very serious tire wear will occur.

3. Submerged arc welding beams, beams fixed

The second step is to fix the cut web and the upper and lower wing plates to weld points, and then weld the beam by submerged arc welding.

4. Welding frame, welding suspension

At this time, the welding suspension must strictly control the size and maintain the squareness, otherwise it will cause tire wear.

5. Connect side beams, welding king pins

At this time, the main beam is basically formed, only the side beams are welded to form the frame structure. And the traction pin traction plate is welded to the position required in the contract, the welding process is required to be high, otherwise the lowbed semi trailer will be skewed.

6. Attach the front neck

Low bed semi trailer with front neck have this process, and flatbed semi trailer do not have this process. The front neck of the low bed trailer is welded up. Welding is done to strengthen the plate. There is no problem with the strength. CIMC have also considered it in advance.

7. Lay the bottom plate

That is, the bottom plate is fully welded on the frame. There is nothing to say at this step.

8. Frosted and painted

Frosting is the previous step of spray painting. Some manufacturers without shot blasting workshops will blow and polish the welding slag with high pressure gas at this stage.

9. Installation the bottom accessories

After spray painting is completed, the bottom travel system is installed, and the assembled bottom is simply mounted and then precisely adjusted.

10. Install the tire

Everyone is familiar here. It should be noted that the air pressure at the factory is generally not the standard air pressure. You must confirm it again after you buy the trailer.

7. How does a low loader work?

Low Loader Trailers are widely used, mainly for medium and long-distance freight transportation. Its frame is a beam-through structure, and the longitudinal beam adopts a straight and live gooseneck type. The height of the webs ranges from 400mm to 550mm, the longitudinal beams are welded by automatic submerged arc welding, the frame is shot blasted, and the beam penetrates the longitudinal beams and welds the whole.

Low Loader Trailers use high-strength international steel material, the vehicle has a lightweight, and guarantees its anti-torsion, anti-vibration, anti-bump ability, and meets different load bearing capacity.

Composed of tandem dry plate spring and suspension support, the structure is reasonable, with strong rigidity and strength, used to support the load and buffer the impact. Low Loader Trailers are usually used to transport heavy vehicles, such as tractors, buses, and special vehicles. Rail vehicles, mining machinery, forestry machinery, agricultural machinery, such as excavators, bulldozers, loaders, paving machines, cranes, etc. And other heavy-loaded goods, the lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high goods and pass overhead obstacles.

When loading mechanical equipment on Low Loader Trailers, the mechanical equipment is usually loaded from the rear of the semi-trailer, that is, the mechanical equipment is moved from the rear wheel frame or the wheels are removed, and then the mechanical equipment is fixed on the semi trailer.
