IN-BOTTOM PLATE PROJECTION RIB TYPE CONTAINER FOR GRAVEL TRANSPORTATION

摘要

PROBLEM TO BE SOLVED: To provide a gravel transportation container for transporting powder loaded articles of a high density such as sand or gravels to a destination directly or by using a ship or a railroad freight car as long-distance mass transportation means with an efficient capacity corresponding to load weight, and having a strength and convenience enabling frequent loading operations by a forklift or the like.;SOLUTION: A gravel transportation container is characterized in that: a vertical-locking type stackable rear wall formed into an upper-open rectangular-solid container shape having a predetermined capacity is provided to be a lower opening/closing type enabling inclined discharging; and in order to increase a distortion strength during the loading operation of a container with a forklift traversing a bottom part rear surface center, a single or a plurality of long steel molded projection ribs having a predetermined height in section is disposed in a bottom plate inner surface longitudinal discharging direction, or intermittently connected corner tube reinforcing means having long upper and lower surfaces communicated with a bottom plate rear surface to sandwich a fork guide is disposed to suppress load distortion.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
