Characteristics and application of low bed trailer

low bed trailer is usually used to transport heavy vehicles (e.g., tractors, buses and special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, agricultural machinery, such as excavators, bulldozers, loaders, paver, cranes, etc.) and other heavy goods, its center of gravity is lower, the better the stability and safety, transport overheight cargo and overhead obstacles by the stronger the ability. low bed trailer usually uses concave beam type (or well type) frame, both the front section of the frame is gooseneck (gooseneck front section of the traction pin is connected with the traction saddle of the traction car, gooseneck rear end is connected with the semi-trailer frame), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels). When the mechanical equipment is loaded on the lowbed, it is usually loaded from the rear end of the low bed semi trailer, that is, by moving the mechanical equipment from the rear wheel frame or removing the wheel, and then the mechanical equipment is fixed on the semi-trailer. low bed trailer is also very wide, suitable for a variety of mechanical equipment, large objects, road construction equipment, large tank, power station equipment machine all kinds of steel transport.

low bed container trailer transporters come in two types: two axle and three axle. Both have front legs. Generally under 13 meters. It used to be 17.5 meters. The load of the full trailer is fully borne by itself and connected with the locomotive only by hook. The locomotive only provides power to help the trailer overcome road friction. The full mount can rely on its own tires to stand upright. Generally about 6.5 meters. Semitrailer and flatbed low loader transporter before leaving factory

Must have a drench system, because in long-distance transportation, a long time to step on the brake will lead to wheel heating, not to take the cooling brake will reduce the effect or even failure, reduce the service life of the hub, axle, tire. Whether it is a big car or a small car, there is an overall consideration before the purchase. Car look at the appearance, line, color, configuration, fuel consumption.Semi trailer frame is mainly composed of girder — welded I-beam, support beam, connecting beam, side beam, lock head, traction pin connecting device, panel, etc.

1.The side beam is generally channel steel or bending parts. At present, most trailers use channel steel. There will be more side beams hanging bending parts in light bodies.
Because the strength requirement is not too big. Support beam is through the beam, now most of the W beam, heavy goods with more than 10# channel steel.

2.King pin is an important component that connects semi-trailer and tractor and bears traction force. It is connected with traction seat. – Forged steel of chrome alloy structure. There are 50# traction pins and 90# traction pins for different cargo tonnage. Generally, the total weight of 50T trailer and cargo is limited, 50# pin is used below 50T, 90# pin is used above 50T, and 90# traction pin is used above 90T for safety.

3.General semi trailer suspension is the use of independent steel plate stamping rigid suspension, a series of leaf springs and suspension.The support is used to support the load and slow down the impact of the dynamic load. Because of the different use of special vehicles, there are different requirements for suspension design. There are four kinds of suspension commonly used: series plate spring balanced suspension, single point suspension, air suspension, rigid suspension (one line and two shafts).

4.Semi-trailer bridge for the support bridge, the main domestic is Guangdong FUWA Axle, BPW Axle, York Axle, Anqiao, guangdong FUWA Axle is the most popular, the bridge through the plate spring and rod and suspension device connected with the frame and frame.The forces that support and transfer loads between wheels. The electrical system of semi-trailer consists of seven-core socket, cable, gas path, various lamps and lanterns, etc., which are used for lighting, safety warning and gas supply for brake.

5.The semi-trailer protection device consists of side protection and rear protection to protect pedestrians and other vehicles from drilling under the semi-trailer.

6.Other accessories on the semi include toolbox, spare tire frame, gantry frame, pile insertion and so on. There are small accessories such as tight rope, rope hook this kind of functional accessories, will be installed according to their own goods.

6.Low boy type semi-hanging features。Low boy semi-trailer cargo is also very wide, suitable for a variety of mechanical equipment, large objects, road construction equipment, large tank, power station equipment machine all kinds of steel transport.

   1.series of low loader semi trailer with flat, concave beam and tire exposed structure, longitudinal beam using straight or gooseneck type. Its frame is step type, the longitudinal beam section is I-shaped, with high stiffness, high strength characteristics.

  2.the main plane of the frame and cargo platform is low, which ensures the smoothness of transportation and is suitable for carrying all kinds of construction machinery, large equipment and steel.

 3.the use of three-axis balance type, two-axis balance type or rigid suspension, in front and rear leaf springs between the mass balance block, can make the deflection of the front and rear leaf springs equal changes, so that the front and rear shaft force balance;

  4.low flat semi trailer series products are suitable for a variety of mechanical equipment, large objects, road construction equipment, large tank, power station equipment, all kinds of just transport, a wide range of uses, efficient and fast. The vehicle adopts advanced computer aided design software to optimize the design flexibly and variously. The load-bearing surface of the frame is designed according to the user’s requirements to meet the transportation of various special goods.
