Vans are very popular in developed cities, and occupy a mainstream position in the developed cities

Van Semi-Trailer

First of all, let's talk about van box truck. Why do many people choose van box truck?

Van box truck now in our daily life has been more common, van box truck can shipped many kinds of goods, such as cold vegetables, general merchandise, dangerous goods and so on, so why do many people like to use van box truck? What are its advantages?

1. First of all, the appearance of the van box cargo truck is relatively simple, it can not only transport goods, but also can be used as ordinary commercial vehicles, most of the van box truck is white, some van box truck cab and container are connected together, can take about 9 people, so it can be used as commercial vehicles.

2. The safety of the van truck transport goods is better, the transport efficiency is higher, it is suitable for short and medium distance transport of goods, the van box truck body is closed, so its roof is closed,it has a good rainproof function.At the same time, the rear of the box truck is provided with a door, some side doors, so it is convenient for loading and unloading of goods. Compartments body adopt high quality steel, good abrasion resistance and resilient, can effectively guarantee the safety of the goods.The whole vehicle is tight, suitable for transportation of all kinds of items, common agricultural products, non-staple food, fruits and vegetables, and so on, generally to downtown supermarket distribution of goods.The general size of the van truck is relatively small, so it's easy to use, stable shape, driving safety is good, suitable for short-distance transport, its oil consumption is low,but fast speed, strong ability to adapt, so van box truck is the first choice for transport goods vehicles in rural villages and towns.

3. The price of the dry van truck is relatively affordable, the overall cost performance is high, the price of the box van truck is in the middle level. In normal circumstances, a van costs about $20,000, including all the paperwork, and the use of the vehicle is also very good, good parts versatility, maintenance is more convenient. The configuration of the van truck is generally higher, the overall quality is still OK, in the cargo transport vehicles, the van box truck belongs to the high-end cargo transport vehicles.

In addition, with the development of the city, many cities have banned lorries from the main parts of the city and the centre of better economic growth, so a lot of light van trucks are complied with the policy, solve the truck stop limit. On the other hand, with the high-speed development of fedex express, also makes the light van truck market number presents a linear trend growth.

Many businesses in order to ensure the safety of goods, part of the shippers will also specify the use of van trucks when looking for cargo transportation. So in the logistics of more developed cities, we can see the prevalence of light van truck scene, at present, van box trucks has begun to occupy the mainstream position in the light truck market.

Drop side wall trailer has a wider supply of goods. Warehouse fence trailer is more suitable for pulling green cargo

warehouse fence trailer

Compared with the van box truck, the loading capacity of the fence drop side trailer is larger, because of its own air permeability, the scope of the source of goods can be wider than the van truck, and it is more convenient than the van truck in loading and unloading.

However, compared with the cargo van truck without weather conditions, the shortcomings of the barn fence semi trailer also highlighted. Especially in the rain, fence cargo trailer need to cover the tent. In addition,warehouse fence drop side trailer is not as anti-theft as van trucks.

At present, the most common warehouse fence semi trailer in our daily life, is to pull the green cargo.

Why is the warehouse fence drop side trailer suitable to pull green cargo?

First, the air permeability of the warehouse fence drop side trailer is good. The green cargo is generally vegetables and fruits. If it is sealed, the green goods are easy to break or even corrupt in summer.

Second,the warehouse fence drop side trailer is convenient for toll station inspection, we all know that the green goods can be free of tolls, so the large toll station for the green goods vehicle are checked more strictly, what the warehouse fence drop side trailer pulled, it's very clear at a glance on general examination, so the warehouse fence drop side trailer do not have to move the cargo to inspect like a van truck.

The loading capacity of the drop sidewall trailer is large, suitable for large goods, much for furniture and building materials transportation

Drop sidewall cargo trailer loading capacity is relatively large, suitable for the transport of large goods, a lot of light throw goods in the case of not super high will also choose to use the drop side semi trailer, because in the price of the van truck and warehouse fence semi trailer, the drop side wall trailer's price is the most affordable and pull the most cargo.

On the existing freight market, the drop side wall trailer is generally mainly used to transport building materials, furniture and some light throw goods. There are also some owners who will add a movable warehouse on the basis of the drop sidewall trailer, so that the drop sidewall semi trailer can be used as warehouse fence semi trailer.

 

The open top van truck has the advantages of both van truck and fence semi trailer

With the advantages of both van truck and fence semi trailer,the open top van truck highlight the advantage obviously, and in the anti-theft aspect is also safer than the warehouse fence trailer. But now many places has cancelled the announcement, truck owners can modify the van truck accordingly, so we can not see the open top van truck.

In addition,because of the light truck box is not long, so light truck users will rarely choose the more popular flying wing vehicle belongs to heavy truck.

For the specific choice, truck drivers can choose the most suitable vehicle according to your local climate, the type of goods to be transported, and the local environmental characteristics.

If the cargo that the truck drivers wants to pull is somewhat special, and the above vehicles do not meet the expectations of the truck drivers, it is best for the truck drivers to consult some old drivers or cargo owners with relevant experience have bought a truck. Only with sufficient experience can you buy your most intimate truck.
