To provide a device for loading long member in a staggered state for effectively load long members with good balance.

A plurality of columnar members (long members) 3 having a protrusion 2 perpendicularly on both ends 3a and 3b respectively along the longitudinal direction are arranged so as to be horizontal and adjacent to each another along the width direction, and thus arranged columnar members 3 are made to be one layer. When the columnar members 3 for one layer are sequentially placed on a loading base 4, each of the layer is deviated for a predetermined dimension for one layer so that the columnar members 3 can be loaded in such a manner that the respective layers are alternate along the longitudinal direction thereof. This device 1 is provided with a pair of frames 5 and 6, a pair of lifting and lowering members 7 and 8, a pair of support members 9 and 10, and a pair of pushing members 11 and 12.
