These dump trucks are really amazing

Dec. 19, 2020

● Rollover dump: the most compliant

At present, in the field of self-unloading and semi-trailer, the compliance degree of rollover and self-unloading is still the highest. Since the maximum length can reach 13 meters, although the height of the fence cannot exceed 60 cm, the loading capacity can still reach about 19 square meters. According to the calculation of 1.6 tons of sand and gravel per square, almost 30.5 tons of cargo can be transported, and the total weight of trucks and cargo can basically reach 49 tons.

● Back flip dump + tarp: crazy exploration

Due to the high lifting height, the length of the cargo box cannot be too long, otherwise there will be a risk of rollover. Today most of its length is 8-10 meters. Since the height of the fence cannot exceed 60cm, the maximum square can only be 14.7 squares.

But now many companies in the industry are adding tarpaulins for the rear dumper. This kind of tarpaulin is intended to prevent goods from being scattered, but I believe everyone knows the actual purpose. I have actually seen a rear dump tarp on the road with baffles installed on both sides after opening, and the height of the tarpaulin can basically reach 60cm, which means that the load can basically be doubled— —This is crazy testing on the verge of breaking the law.

● Mid-dump dump: Quietly violated

In addition to the above two types of self-unloading methods, there is also a "mid-turn self-unloading" for normal dumping and semi-trailer. It is said that the coal transportation industry in Inner Mongolia and other places is popular. This kind of car looks like a warehouse truck, but in fact there is a hydraulic cylinder at the bottom of the cargo box, which can lift the middle of the floor and dump the cargo from both sides of the cargo box.

But in fact, at the same time that flatbed dump semi-trailers were banned, this model is no longer in compliance, because the original text of the relevant regulations is: "The loading position of flatbed trucks and barn trucks The self-unloading structure should not be used for cargo with lifting function".

● Conveyor belt dumping: hit a side ball

Starting from the end of 2019, a new model has gradually emerged in the industry. The announcement name of this type of vehicle is "grain transporter", which uses a conveyor belt to unload the goods, and the volume of the cargo box can basically reach more than 40 cubic meters.

But in fact, this kind of "grain transporter" is now transporting high-density bulk materials such as sand and gravel. If calculated according to the density, overloading must happen frequently-but the vehicle itself is a compliant model, which is accurately hit. The policy's sideball.

● Tank-type dumping: undoubtedly illegal

Compared with the previous violations, the tank dump is very straightforward. The prototype of this model is the "lifting powder material transport vehicle", which is mainly used to transport some powder materials with low fluidity. When the air force cannot be discharged normally, the lifting method can be used for unloading. material.

However, for the convenience of transporting sand and gravel, some people cut off the top and tail of the tank after going to the house to make it into a rear-tipping and self-unloading semi-hanging style. The loading capacity is even more amazing. This kind of car can actually be easily judged as an offending vehicle.
