What are the types of low loader semi-trailers and tractors? How to maintain our low loader semi-trailer? Below I will share with you the basic knowledge and maintenance knowledge of our semi-trailer. Welcome friends to send us messages and inquiries.
The semi-trailer is composed of a semi-trailer tractor and a semi-trailer, and has been widely used for its advantages of strong specialization, large loading capacity and fast transportation.
The traction connection device on a semi-trailer usually uses a traction pin. Usually, the traction pin is connected to the traction seat of the tractor. Part of the load of the trailer is borne by the tractor through the traction seat. The support device is used to maintain the balance of the semi-trailer when it is off-hook.
Full trailer: refers to a trailer with at least two axles, which is connected to the traction hook of the tractor by the hanging ring on the traction rod. The traction rod has both traction and steering functions. According to the number of axles, full trailers can be divided into single axle, dual axle and multi axle trailers.

There are three types of low flat bed semi-trailer frames: flat, gooseneck and recessed 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, so that it has 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. We can also make different types of cars, such as pulling low flats, which can be used to transport extra-long goods or wind blades. It can also be used as an ordinary semi-trailer with multiple functions.

low loader trailer: Also known as a gooseneck. The semi-trailer frame has a stepped shape, and the plane of the cargo platform is behind the gooseneck, so that the main plane of the cargo platform is lowered, which is convenient for loading and unloading and transportation of goods. Our split gooseneck semi-trailer has a detachable gooseneck design on the front, which avoids overturning the body when transporting heavy equipment and ensures the safety of the car and the driver.

Special trailer: refers to a vehicle used to undertake special transport tasks or special operations and other special purposes. It has special carriages and auxiliary devices and is only used to transport a certain kind of goods or a specific form of goods. For example: powder tanker trailer, fuel tanker trailer, acid tank trailer, etc.
Maintenance knowledge about heavy transport trailers
(1) Visually check that there is no lack of gas and foreign matter adhesion, and then check whether the steel ring is deformed or cracked.
(2) Pay attention to the suspension system of the low loader semi trailer and see the tightness of all the nuts and bolts and U-bolts. This is all about whether the tires are 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 a few times to see if there are any cracks in the welds. Especially the riders who are now running and hanging must pay attention to this problem.
(4) Feel the wear of the moving parts, reach out and touch the small parts such as box hinges, box hooks, cuttings, container locks, etc. to see if there are any cracks and breaks. Just look at the touch, do n’t be abnormal, just turn on the car and see if there are any bad lights. There is no shortage of reflective signs. I believe there must have been a penalty on the road for defective reflective signs.
(5) The regular maintenance of the engine is very important. Many professional maintenance masters said that among the low loader semi trailer they repaired, the failures caused by poor engine maintenance accounted for 50% of the total failures.
(6)The brake hoses and hydraulic hoses must be checked frequently for rubber aging and replaced as soon as they are found.
