What is low bed trailer?
A lowboy is a specialty trailer whose defining characteristic is that the deck height drops twice. The first drop is directly after the gooseneck. The second occurs before the wheels. As the name suggests, a lowboy trailer has a very low deck to accommodate the transport of tall items, especially items that may be too tall to legally be transported on a taller trailer deck.The main types of low loader transport trailers are two-axle, three-axle, four-axle, high-low-high, etc. (Depending on the number of axles and tire size, the carrying capacity of a low loader trailer is also different. The more axles it has, the more cargo it can carry.
Types of low bed semi trailer
There are three types of low-bed semi-trailer frames: flat beam, gooseneck beam, and concave beam.
Low-bed semi-trailer:
The entire cargo platform is straight and above the wheels. The upper space of the overlapping part of the tractor and the semi-trailer is fully utilized, giving it a large cargo platform area. This type of frame structure is relatively simple and easy to manufacture and is mostly used for super-heavy trailers.
RGN trailer (detachable gooseneck trailer):
Also known as gooseneck low trailer. The semi-trailer frame is stepped, and the cargo platform plane is behind the gooseneck, which lowers the main plane of the cargo platform and facilitates the loading unloading, and transportation of cargo.
Concave beam type:
The cargo hold plane is concave, and the load-bearing plane is the lowest. It is generally suitable for transporting large or super-high equipment.
Lowboy trailers have a wide range of applications covering multiple industries. Due to their compatibility with heavy loads, they are the preferred choice in oil and gas, mining, agriculture, construction, forestry, and related industries. Lowboy trailers can be used for rail cars, machinery, construction assets, and other difficult-to-transport loads, saving you time and money while delivering the required resources on-site.
How to maintain lowboy semi trailer?
1.Visually check for deflation and foreign matter, and then check if the steel rim is deformed or cracked.
2.Pay attention to the suspension system of the low loader semi-trailer, and check the tightness of all nuts, bolts, and U-bolts. This depends entirely on whether the tire is eaten. Otherwise, if there is a problem, it will be troublesome.
3.Shake the outriggers to make sure they are normal. Check the outriggers and shake them several times to see if there are cracks in the welds. Especially for riders who are running and hanging now, be sure to pay attention to this problem.
4.Feel the wear of the moving parts, reach out, and touch the small parts such as the box hinges, box hooks, cutouts, container locks, etc. to see if there are cracks and breaks. Just look at the touch, don't be abnormal, just open the car and see if there are any broken lights. There is no shortage of reflective signs. I believe that on the road, you will be punished for defective reflective signs.
5.Regular maintenance of the engine is very important. Many professional maintenance masters said that among the low loader semi-trailers they repaired, the failure caused by poor engine maintenance accounted for 50% of the total failures.
6.Brake hoses and hydraulic hoses must be checked regularly for rubber aging and replaced immediately if any aging is found.
