<p>The present invention relates to a material lifting box comprising: a body becoming wider from a lower part to an upper part; an opening where materials come in and out; and a transferring roller installed inside an inner surface of the body to be able to rotate. Accordingly, the present invention is capable of preventing damage to the materials by reducing friction and impact to the material during a process where a worker on a lower layer pushes up the materials by adhering the materials to the transferring roller, enabling a worker to easily lift by reducing the movement of the materials. In addition, the present invention is capable of preventing internal defects of the interlayer slab opening formed to lift the materials.</p> |
