  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cargo covering device for a trailer and a method of operating the same, and more particularly, to a cargo covering for a trailer capable of easily and stably covering the outside of cargo loaded on the trailer. The present invention relates to a cloth device and a method of operating the same.

  Generally, in the case of a trailer for bulk cargo that transports a coil wound of a steel plate or a steel wire from a steelworks to a customer, the number of coils weighing 2 tons is limited to 14 to maintain the specified load. To load.

  Further, in the case of rainy weather or heavy snowfall, a wrapping device for wrapping the coil outside the trailer is provided to protect the steel plate or the steel wire coil loaded on the trailer from moisture.

  At this time, the covering device according to the related art has a structure as shown in FIGS.

  However, the conventional covering device shown in FIGS. 1 and 2 has a structure in which a large number of members are bound into a complicated structure. There is an inconvenience.

  Specifically, the conventional covering device is a structure that is used by being attached to the trailer only in rainy weather or snowfall, and cannot be easily attached and detached. Therefore, there is an inconvenience that it takes a long time to mount and remove the device, and transportation is substantially delayed. In addition, with the separate securing of the conventional crawlers with a wrapping device, two units are required, one for rainy weather and the other for normal times, and there is an inconvenience of increasing the transportation cost.

  In addition, since the wrapping device according to the conventional technique is heavy and increases the load on the trailer, it is inevitable to remove a part of the coil loaded on the trailer from the trailer in order to maintain the specified load. There is a disadvantage that the removed coil is transferred to another trailer.

  Furthermore, the covering device according to the related art, when formed on the trailer with the same width as the trailer, has a disadvantage that the coil is damaged by interference with the coil loaded on the trailer. Furthermore, the wrapping device according to the prior art is a structure having a fixed width and not a variable structure, which allows the wrapping operation to be performed when the size of the cargo to be loaded is exceeded. Is impossible. When the width of the wrapping device according to the conventional technique is set to be larger than the width of the trailer, there is a disadvantage that it is difficult to secure a rear view of the driver.

  Therefore, at present, it is desired to develop a technology capable of solving these conventional disadvantages.
