Freight companies all over the world have towed a variety of professional trailers on every road imaginable. It is possible that you have seen quite a few low loader trailers (even if you may not know it yet). Low bed trailer, also called double crane, low loader, low bed or buoy, depending on which part of the world you are in, is a semi-trailer with a hanging deck.
A low trailer has two drop points on the deck. The first drop point is behind the gooseneck and the second drop point is before the wheels, which allows the trailer to sit on the ground.
The drop in the trailer is designed to allow the transportation of oversized items or equipment that exceed the normal transportation height limit (usually any cargo over 8 feet in height).
Low bed trailers are usually used to haul heavy equipment and machinery, such as excavators, bulldozers and other large construction equipment. Low loader trailers are ideal for hauling such large equipment because they are usually tall and wide and exceed the standard legal height and weight limits. The maximum weight of a two-axle low-lift trailer is 40,000 pounds, but the weight limit can be increased to 80,000 pounds of the total trailer weight, and the load depends on the number of axles required. Low-lift trailers can handle cargo with a maximum height of 14 feet or less. For reliable trucking services and equipment transportation, low-lift trailers are essentially designed to transport oversized cargo, which usually exceeds the legal height requirements of flatbed trailers.
Low loader semi trailer
Low loader trailers are usually used to transport heavy trucks (such as tractors, buses, special vehicles, etc.), railway vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, pavers, etc.) , Cranes, etc.) and other heavy objects. The lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high cargo and overcoming obstacles.
Low bed trailers are also very extensive, suitable for the transportation of various mechanical equipment, large objects, road construction equipment, large storage tanks, power station equipment and various steel materials.
Structure and loading of low bed trailer
Low bed trailers usually use a concave beam (or tic-shaped) frame, that is, the front of the frame is a gooseneck (the traction pin at the front of the gooseneck is connected to the traction saddle). For tractors, the rear end of the gooseneck is connected to the semi-trailer frame (connected), the middle part is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels)..
When loading mechanical equipment on a low altitude semi trailer, the mechanical equipment is usually loaded from the rear of the semi-trailer, that is, the mechanical equipment is removed from the rear wheel frame or the wheels, and then the mechanical equipment is fixed on the semi-trailer on.
1. The low bed semi trailer series has a flat, concave beam and exposed tire structure, and the longitudinal beam adopts straight or gooseneck tubes. 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 various construction machinery, large equipment and steel.
3. It adopts three-axis balance, two-axis balance or rigid suspension. Mass balance blocks are installed between the front and rear leaf springs, which can change the deflection and balance force of the leaf springs front and rear. On the front and rear axles.
4. The low bed semi trailer series products are suitable for the transportation of various mechanical equipment, large objects, road construction equipment, large storage tanks, power station equipment and various steel materials. It has a wide range of uses, and is efficient and fast. The whole vehicle adopts advanced computer-aided design software, which is optimized for flexible and diverse designs. The load-bearing surface of the frame is designed according to user requirements, which can meet the transportation of various special goods.
