According to the new annual inspection regulations of the brand-new blue dumper, the total weight is the key to strictly inspect the "big ton and small standard" car. For all large trucks with a total mass greater than or equal to 4500kg, those whose body-in-white quality is not up to standard (overweight) will not be able to apply for annual inspection and transfer of property rights.

Driving a car that has not passed the annual safety inspection belongs to an individual unlicensed operation. Will be punished accordingly. Two-axle trucks are divided into two categories, one is blue brand trucks, generally 4. 2m dump truck, and the other is other two-axle trucks. In terms of charging standards, the number of dump trucks is greatly reduced, but at the same time, it is clearly stipulated that the total weight of white body of blue brand trucks should not exceed 4.5 tons, which is likely to reduce the loading quality to some extent.

Dump truck is a fully automatic truck that loads and unloads goods according to hydraulic press or mechanical equipment, which can also be called engineering dump truck;

Dump trucks generally consist of chassis, hydraulic lifting mechanism, cargo box and its four-circuit protection valve device. There are two kinds of dump truck boxes: backward tipping and side tipping, which basically adjust the fitness movement of hydraulic cylinders according to the control system software. It is more common to encounter dump trucks that turn back now. According to the hydraulic cylinder, the car body rotates, and few dump trucks rotate in both directions.
