PURPOSE:To prevent the occurrence of vibrations and rocking movements during transfer, by extruding plural racks along a guide rail via their wheels in regular sequence, while bringing an interval in a horizontal direction between paralleled racks into almost nothing, and stacking these long works housed in the rack in high density. CONSTITUTION:A lot of cement pipes S arranged horizontally and parallelly are fed to a curing chamber 1 with a feed conveyor 7 and supported by plural pieces of concave grooves at an upper part of a bar 9 of a loading device 10. This bar 9 is made horizontally shiftable on a lifter in both directions. A pair of guide rails is extendedly installed in horizontal form at the inside of both side walls in a rack flow direction of the curing chamber 1, while each rack 2 mounted with an unhardened cement pipe S and an elevator 4 are delivered to an upper part of the curing chamber 1 by a driving device 5 and they are stopped at the same level. Then, the rack 2 is extruded onto these rails 21 by an extruding device 22 without vibrating it, shifting each in a close state, thus these long works are stacked in high density.
