Description

  The present invention relates to an assembling box pallet that can be transported by a forklift and an assembling method of the assembling box pallet. In particular, the assembling box pallet is excellent in durability and does not protrude from the size of a flat pallet body. And an assembling method of the assembling-type box pallet.

  For example, there is a flat type resin pallet as a pallet (loading platform) for carrying many loads at once with a forklift (see, for example, Patent Document 1). Since this pallet is flat, it can be stacked in stages when only empty pallets are transported, and because it is made of resin, it is lightweight and has excellent transportability by trucks etc. There is.

  In addition, there is a box pallet formed of sturdy iron or the like so that the pallet can be stacked and stacked on a truck or the like with a load placed on the pallet (see, for example, Patent Document 2).

  However, with flat pallets, pallets cannot be stacked in layers when loading cargo on trucks, etc., and with box pallets, empty pallets are wasted when transported by truck. There was a demerit that the space increased and the loading efficiency was poor.

Thus, an assembly-type box pallet is known in which an iron frame can be attached to a flat resin pallet as a box pallet by taking advantage of both advantages (see, for example, Patent Document 3). With this assembly-type box pallet, when carrying luggage on a truck, etc., it is used as a box pallet and stacking pallets in multiple layers to increase the loading efficiency of the luggage, and after removing the luggage, remove the frame part By using a flat pallet, there is an advantage that empty pallets can be stacked and transported without waste.

  As described above, the conventional assembling box pallet has a shape in which an iron frame is fitted on the outer side of the flat resin pallet, so that the main body size is larger than that of the flat resin pallet. Therefore, if the size of the truck's cargo compartment is determined according to the existing dimensions of the pallet body, only a few of these assembly-type box pallets can be stacked, and the planned number of pallets cannot be loaded. On the other hand, there was a problem that the loading efficiency deteriorated.

  Also, when stacking multiple box pallets, and when stacking box pallets made of iron, etc., the lower pallet's steel frame and the upper resin pallet interfere during transportation. However, there was a problem that the resin pallet was damaged immediately.

  Further, when arranging the resin pallets with a forklift without gaps, there has been a problem that the corners of the resin pallets are applied and the corners are damaged.

  Therefore, the present invention improves the loading efficiency by preventing the box frame housing part from protruding from the main body dimensions of the flat pallet, and prevents damage to the flat pallet by increasing the strength of the four corners of the flat pallet. It is an object of the present invention to provide an assembling-type box pallet and an assembling method of the assembling-type box pallet.

  The assembling-type box pallet in the present invention includes a flat pallet and an assembling box frame accommodating portion that is detachably mounted on the flat pallet.
