Description

Cargo box of freight car with net for prevention of cargo moving}

The present invention relates to a cargo box structure of a cargo vehicle equipped with a cargo movement prevention net. More specifically, in a cargo vehicle for loading cargo packed in small boxes, a cargo box structure of a vehicle equipped with a cargo movement preventing net which can be mounted while changing its position in the longitudinal direction of the cargo box according to the cargo load amount will be.

In the conventional freight transport truck, there is a cargo fixing structure in which a loop is formed around the storage box and the cargo is fixed using a rope, or a lashing bar is formed on the left and right inner walls of the storage box. Although it is effective for fixing a cargo unit such as a certain size of cargo or a roll container loaded on the container, it is not effective for fixing a cargo packed in a small box unit and has a problem such that the cargo is damaged by excessive force.

In addition, there have been devised to use a belt or net to prevent the flow of cargo in the trunk of the passenger car, but because the cargo load in the passenger car is limited and the volume of the trunk is small, it is possible to change the position of the belt or the net according to the cargo load. It wasn't the way it was fixed.

In addition, there is a design to adjust the height of the net in the trunk of the passenger car, but this was intended to facilitate the work rather than to respond to changes in the cargo load.

On the other hand, the cargo loading vehicle is retracted and docked with the rear door of the loading box open on the cargo terminal deck or conveyor for the unloading of the cargo. When the cargo is moved using a pallet or roll container When the cargo does not fall during the movement, but the bulk of the cargo packaged in a number of small box units in the bulk was dropped and damaged by the flow of cargo.

As a result of intensive studies to solve the problems of the conventional cargo movement prevention structure as described above, by adding a first mesh net that is free to install and detach to the cargo box structure of the cargo vehicle having a conventional lashing bar, The present invention was completed by discovering that the same small cargo can be effectively fixed according to the load to prevent the flow and damage of the cargo.

Further, in addition to the cargo fixing structure during cargo transportation as described above, by installing the curtain-type second net inside the opening door of the loading box, the load is opened even when the vehicle is opened and the vehicle is operated when docking for cargo unloading. It has been found that the fall and thus damage of the can be prevented.
