Lowbed semi trailer size and selection
Lowbed semi trailer is usually used to transport heavy vehicles (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, engineering machinery (such as excavators, bulldozers, loaders, pavers, cranes, etc.) and other heavy loads. Low platform semi-trailer has many sizes. Today, we will mainly talk about the size of low platform semi-trailer and how to select the appropriate size of low platform semi-trailer.

Lowbed semi trailer usually adopts concave beam (or well type) frame, namely, the front section of the frame is gooseneck (the traction pin of the front section of the gooseneck is connected with the traction saddle on the tractor, and the rear end of the gooseneck 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).

Lowbed semi trailer size and configuration parameters

Lowbed semi trailer is mainly used for the transportation of large non removable equipment, such as excavators, loaders, pavers, rollers, etc.

The model size of lowbed semi trailer: 9.3m, 10.5m, 11.5m, 12.5m, 13m and 13.75m, and the width is 3m. The lowbed semi trailer is divided into two axles, three axles, and three wire six axles. The height of the cargo load surface can be 800mm-1150mm.

Axis size: one line two axle lowbed semi trailer, one line two axle, 8 tires, two line four axle lowbed semi trailer, 16 tires, three line six axle lowbed semi trailer, 24 tires.

Lowbed semi trailer configuration: the longitudinal beam is 500mm high, the upper wing plate is 20mm, the lower wing plate is 20mm, the web plate is 8+8mm, and the side beam is 300mm. Bottom plate 5mm pattern, 100 tons. Three line six axle or four line eight axle, five line ten axle, standard steel ring, one spare wheel frame, 28t outrigger.

Tyres: 12R22.5, 1100R20, 1200R20.

How to measure the size of a lowbed semi trailer

1. Clearance radius Rw of a low bed semi trailer: the distance from the center of the traction seat to the nearest vertical line of the cab rear wall or spare wheel stand or other accessories such as air filter, exhaust pipe, etc. (It is necessary to know the front turning radius Rf of the lowbed semi trailer) Rw Rf ≥ 150mm.

2. Rear slewing half Rc of a lowbed semi trailer: the vertical distance from the center of the traction seat to the farthest point at the rear end of the tractor frame (know the clearance radius Rr of the lowbed semi trailer) Rr Rc ≥ 70mm.

3. No load saddle height H: height of the drawbar from the ground h (there are front depression angle and rear elevation angle between them, which can be adjusted according to the road conditions and axle load distribution optimization).

Applicable scenarios of varies sizes of lowbed semi trailer

Lowbed semi trailer has a wide range of application scenarios, which are applicable to the transportation of a variety of mechanical equipment, large objects, highway construction equipment, large tanks, power plant equipment, and various steels. Lowbed semi trailers of different sizes are used to transport goods of different volumes.

What is the loading capacity of the lowbed semi trailer?

According to the number of axles and the size of tires, the load of low platform semi-trailer is different. The more axles, the trailer the load. The load range of a lowbed semi trailer is 20-150 tons.

Type of lowbed semi trailers

The main types of lowbed semi-trailer are: two axles high and low, two line four axle high and low, three axle high and low, three line six axle high and low. Generally, the larger the number of shafts, the larger the size.

How to choose an appropriate size lowbed trailer?

The series of lowbed semi trailers for conventional mechanical transport have dimensions of 8.8 meters, 9 meters, 9.3 meters, 9.5 meters, 10.5 meters, 11.8 meters, 12 meters, 12.5 meters, 13 meters, 75 meters, etc., and a width of 2.8 meters to 3 meters. In addition to the conventional dimensions, the lowbed trailers for heavy cargo transport also have multi axis trailer trailers of 15.5 meters, 16 meters, 17 meters, 22 meters, etc., with a width of 3.2 meters and 3.4 meters. Large cargo transport certificates are required before they can go on the road. The styles include high and low boards, high and low boards, three axes, two lines, four axes, three axes, three lines, six axes, five lines, ten axes, four lines, eight bridges, six lines, and twelve bridges.

Both heavy cargo transport and conventional mechanical transport lowbed semi-trailer can be used to pull mechanical equipment, excavators, bulldozers and other large equipment, with a load of 30 tons, 50 tons, 60 tons, 80 tons, 100 tons, 120 tons and 150 tons. Low flat plates can be pulled, and optional hydraulic ladder cars can be installed. The low level of the rack column ensures the stability of transportation, and are suitable for carrying various engineering machinery, large equipment and steel.

High strength steel is basically used as the traveling structure of both ordinary mechanical transport and large piece transport low flat semi-trailer. The vehicle has light deadweight, and its anti twisting, anti seismic, anti bumping capabilities are guaranteed to meet different road bearing capacities.

13 m lowbed semi-trailer, 12 m lowbed semi-trailer, 11 m hook plate semi-trailer, 10 m high lowbed semi-trailer, 9.5 m trailer, light concave beam hook plate trailer, lowbed semi-trailer with exposed tires, 13 m trailer tray, high and lowbed semi-trailer, three axle lowbed semi-trailer, mechanical transport semi-trailer, flat excavator transport vehicle.
