1. What kind of goods to be pull?

The pulled cargo determines the type of semi trailer.

Low Bed Semitrailer

Low bed semi trailer parts without railings, widely used, mainly used for long-distance freight transport. Series semi trailers frame is beam - through structure, longitudinal beam adopts straight live gooseneck type low bed semi trailer. The height of the web is from 400mm to 550mm, the longitudinal beam is welded by automatic submerged arc welding, the frame is shot peening, the beam is penetrated into the longitudinal beam and welded as a whole. Series of dry plate spring and suspension support, reasonable structure, with strong rigidity and strength, used to support the load impact.

Low bed semi-trailer is usually used to transport heavy vehicles (e.g., tractors, buses and special vehicles, etc.), rail vehicles, mining machine 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. The low bed trailer weight is light, and to ensure its anti - twist, anti - earthquake, anti - bump ability, to meet the different road bearing capacity.

Fence Semitrailer

Fence semi - trailer is a semi - trailer designed with warehouse structure. It is mainly used for the transportation of agricultural and sideline products and other light foam goods.This structure is designed to prevent light cargo or bags from falling off.And the fence semi trailers can be used to transport poultry livestock.

Drop Side Semitrailer

A semitrailer with a slatted structure for loading parts. Widely used, mainly suitable for medium and heavy and bulk cargo long distance transportation, applicable, has become the first choice of medium and long distance freight trailers.

Gooseneck Semitrailer

Gooseneck semi-trailer is also widely used to carry a variety of machinery and equipment, large items, highway construction equipment, large tanks, power plant equipment and various steel transport.

Flatbed Semitrailer

Series semi trailer has flat plate type, concave beam type and tire exposed type structure, longitudinal beam adopts straight type or gooseneck type, its frame is ladder type, longitudinal beam section is I-shape, with high stiffness, high strength characteristics. 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 large equipment of construction machinery and steel.

The use of three axis balance type active rigid suspension, between the front and rear plate spring is equipped with a mass balance block, can make the front and rear plate spring deflection of the same amount of change, the use of rear shaft force balance, etc.. Widely used, efficient and fast, the flatbed semi trailer adopts advanced computer aided design software, flexible and diverse optimization design, according to user requirements to design the bearing surface of the frame, to meet the transportation of various special goods.

Dump Semitrailer

Dump semi trailer is suitable for coal, ore, construction materials and other bulk transport of scattered goods.

Dump semi-trailer can be divided into two kinds according to the use: one belongs to the heavy-duty and super-heavy-duty dump trailer for off-road transportation mainly undertake the transportation tasks of large mines, projects and so on, usually used with excavators. Another belongs to the road transportation of light and medium-sized ordinary dump trailers mainly undertake the transportation of sand, soil, coal and other loose goods, usually with the use of loaders.

Container Semitrailer

A semi-trailer with container structure for loading. Mainly used for ships, ports, routes, highways, transit stations, Bridges, tunnels, multimodal transport supporting the logistics system.Sunsky uses skeleton semitrailers to transport containers, and skeleton semitrailers are equipped with container locks to hold containers in place.

Tank Semitrailer

Tank semi-trailer with a tank structure for loading parts. Mainly used for transporting liquid, bulk materials and bulk cement, etc.

2. How many tons cargo are you pulling?

Semi-trailer pull multiple goods, first of all to see what is the configuration of the trailer to buy, the most common configuration semi trailer can pull about 40 tons, high configuration semi trailer can pull about 120 tons. There is also to see what goods to pull, if pull daily necessities, no matter how high the configuration can not pull 100 tons, if it is coal or steel,can pull more.

4 x 2 tractor matching 3 axle semi-trailer belongs to the 5 axis semi-trailer, according to a new overload limit standard, the total weight of goods and trailer can't more than 42 tons, namely the weight of the tractor plus maximum allowed traction weight can not be more than 42 tons.So when choosing a tractor,maximum traction weight is very important,this parameter basically decided the tonnage of the cargo that you can pull, in principle pull the largest tonnage of goods is the allowed traction tonnage minus semi trailer deadweight tonnage! The weight tonnage of general three-axis ordinary flatbed semi-trailer is about 6.5 tons, so if you choose a quasi-towing tractor of 26 tons, you can only pull 19.5 tons of goods, and select a 35-ton tractor to pull 28.5 tons of goods!

The total weight of 9.6m truck trailer with cargo shall not exceed 17 tons. The deadweight of the trailer is about 6-8 tons. The chassis height of single-bridge container van semi trailer is generally about 1.3-1.5 meters. The width of the cargo compartment is about 2.3-2.4 meters. The internal loading height of the compartment is about 2.5-2.7 meters.Carriages of the container trailer can hold about 50-55 cubic meters of goods (according to experience, the smaller the volume of goods, the more actual number of goods can be loaded. If the volume of goods is larger, the virtual side is more, which will waste a lot of space.

container van trailer suitable for loading goods: 9.6m single axle container van trailer is more suitable to undertake a variety of valuable materials, light goods and goods with waterproof requirements for transport.

3. What's the roads situation?

Make sure you're familiar to the road you always drive. This is very important for tire selection.

First of all, there are steel wire tires and vacuum tires. These two kinds of tires are subdivided into a variety of models. Different models are adapted to different trailer models.

At present, the most common ones in the market are 11.00R20 steel wire tire and 12.00R22.5 vacuum tire, and most of them are drop side dump trucks and all kinds of dangerous chemicals vehicles. Among them, 12.00R22.5 vacuum tire with good long-distance road condition is mostly matched, and the pattern is mostly 3 or 4 lines along.

Poor road conditions and short distance can be matched with 11.00R20 steel wire tire or 12.00R22.5 series of vacuum tire, at present, 12R22.5 and 12-layer vacuum tires are the majority, but the actual application,16 layers, 18 layers of vacuum tire is the majority.As we all know, the higher the tire level, the higher the durability, and thus the greater the safety.

825-16 vacuum tire /820-R20 steel tire is generally used in low bed semi trailer, three lines and six axles semi trailers, especially in the 13.75-meter flatbed semi-trailer. This tire has small diameter and low bearing surface, and the current hierarchy is mostly 16 layers.

235/75R17.5-16PR and 317/70R22.5 are widely used in standard coupe semi-trailers and mid-axle coupe vehicles.

Points for attention when using trailer tires

Late purchase tires should pay attention to the delivery time on the tire, replace the tire on the same axle should be installed with the same brand, specifications, levels, pattern of tires, can not be mixed.

When using, try to avoid long time overload use, timely check tire wear and tire pressure, otherwise the service life of the tire will be reduced by 20%-50%.

In view of the safety problem of tire driving, driving for a long time, or road conditions are bad, frequent braking, will make the tire fast heat,you need to install a water drench to the tire in time to cool down, prevent tire pressure is too high lead to tire burst, endangering driving safety.

In fact, about this problem, at present, domestic and foreign trailer trucks have begun to install tire pressure monitoring and alarm system, according to the pressure sensor installed in the tire, give a timely signal, control tire pressure through the charging and discharging device, so that keep it at safe tire pressure at all times.

As a crucial part of the semi-trailer, the tire is related to the safety of the truck trailer. In particular, the hot weather is also a high incidence of tire problems,so pay extra attention. Periodically check the tire pattern wear degree, reasonable replacement, timely replace hidden trouble tires to avoid unnecessary losses.
