APPARATUS FOR LOADING A HEAVY-WEIGH OBJECT

Disclosed is a heavyweight object loading apparatus. The heavyweight object loading apparatus according to an embodiment of the present invention includes a table where a heavyweight object is loaded; a loading plate that maintains a state of protruding upward from an upper plate of the table in an initial state, the heavyweight object being loaded before the upper plate; a lifting/lowering plate that is arranged below the loading plate and supports the loading plate; an elastic member that is interposed between the loading plate and the lifting/lowering plate and elastically supports the loading plate with respect to the lifting/lowering plate; a pneumatic cylinder unit that provides a driving force for lifting/lowering the lifting/lowering plate; a first direction control valve that maintains an initial position of the lifting/lowering plate by supplying compressed air to the pneumatic cylinder unit in a first state before the loading of the heavyweight object on the loading plate and blocks the supply of the compressed air to the pneumatic cylinder unit, discharges the compressed air from the pneumatic cylinder unit, and lowers the lifting/lowering plate below the upper plate in a second state after the loading of the heavyweight object of the loading plate; and a second direction control valve that supplies the compressed air to the first direction control valve when the lifting/lowering plate reaches the lowest position so that the first direction control valve returns to the first state.
