PURPOSE: To cover and uncover the loading platform with the sheet cloth quickly and easily by a method wherein an elevating arm is moved vertically by means of an elevating device fitted at the front of the loading platform and a sheet cloth furling rod is moved along said arm in order to furl or unfurl the sheet cloth with said sheet cloth furling rod during the moving.

CONSTITUTION: The automatic covering and uncovering apparatus 1 of the loading platform covering sheet cloth is provided at the front right side of the loading platform 3. Said apparatus 1 consists of the elevating device 4, the elevating arm 5, a driving device for furling sheet cloth 7, which moves within said arm 5, the sheet cloth furling rod 11 and the loading platform covering sheet cloth 12. And, by the extension and contraction of the hydraulic cylinder 44 of the elevating device 4, the elevating arm 5 is moved vertically within a guide column 43. Stillmore, by driving the mobile motor 8 of the driving device for furling sheet cloth 7, said driving device 7 moves guided with a L-shaped guide rail 6 over the range from the one end 64 to the other end 65. At this time, the sheet cloth furling rod 11 pivotally supported by the driving device 7 is also moved in a similar manner. By driving a sheet cloth furling motor 9, the loading platform covering sheet cloth 12 is furled or unfurled to or from the furling rod 11.
