[

The body assembly 1500 is composed of at least two square pipes and a rear wheel shaft 1510 extending to one side to become the central axis of the trailer and can be attached to the lower portion of the nitrogen tank tray.

That is, the body assembly 1500 can be configured to lift and load the nitrogen-filled trailer, thereby increasing the convenience of movement of the nitrogen-filled trailer.

The hose storage units 1610 and 1620 may include a low pressure throttle throttle and a high pressure throttle throttle which are coupled to the side of the pressure control apparatus 3000 and are differently used depending on the pressure of the gas.

More specifically, a low-pressure automatic hose reel and a high-pressure automatic hose reel are combined on both sides of the pressure control device 3000, and a low-pressure hose and a high-pressure hose are used according to the required pressure. The hose can be automatically rewound by the provided elastic body.

The control panel 3200 also displays the current pressure of the nitrogen gas supplied from the pressure distributing apparatus 2000 and the amount of gas in the nitrogen tank to the exterior and is controlled by a valve 3210 located above the control panel 3200 When a command occurs, commands can be passed to each component.

The boosting device 3300 adjusts the pressure of the nitrogen gas by a command received from the control panel 3200 and when the pressure in the boosting device 3300 falls below a predetermined pressure, Can reduce the space in the pressure-elevating device 3300 by the same principle as that of the piston, thereby raising the pressure of the nitrogen gas.

When the pressure in the booster 3300 becomes equal to or higher than a preset pressure, the relief valve 3400 is automatically opened to release the nitrogen gas to prevent the pressure of the gas in the booster 3000 from rising.

In addition, the filter 3500 can separate foreign substances such as moisture existing in the nitrogen gas and supply nitrogen gas of high purity.

Hereinafter, the process of loading the nitrogen tank in the upper tray assembly 1110 will be described in more detail with reference to FIGS. 7 to 14. FIG.

Figure 7 shows a view 70 in which the upper tray is fixed before loading the nitrogen tank and Figure 8 shows the view 80 in which the upper tray is moved to the rear end to load the nitrogen tank .

That is, in order to load the nitrogen tank, the upper tray is moved to the rear end as shown in FIG. 8 in the fixed state of FIG. 7, so that the loading of the nitrogen tank can be prepared.
