Description

Cart for the board transporting}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bogie for conveying a sheet material, and more particularly, to a bogie conveying bogie for conveying a sheet material such as a gypsum board or a plywood, will be.

Generally, in case of gypsum board or plywood which is mainly used in construction site or manufacturing site, it is moved by using equipment such as a crane or forklift when it is transported in large quantities. In a place where a crane or a forklift is difficult to enter, In the case of transferring a small quantity of water to the installation site from the place where the Siena sheet is transferred to the installation site, workers are carrying one or two sheets one at a time, and when using the crane or forklift, the cost is high. The work efficiency is significantly lowered.

In order to solve these problems, a technique has been developed in which the gypsum boards or plywood boards can be transferred in large quantities at one time. Among them, Korean Utility Model No. 24692, 1999 (July 5, 1999 As disclosed in the Japanese Patent Application Laid-Open Publication No. 2003-24305, a handle is provided to push and pull one side of a base provided with a wheel at a lower portion thereof so that the object to be transported is loaded on the base and can be transported in a large amount at a time. A plurality of partitioning members are provided on the upper part of the cargo space of the base so as not to collide with each other while separating the transported objects. However, existing transportation wagons are merely attached to the base and the cargo space When loading a large number of objects to be transported, the position of the base is close to the ground Since it is low in height, it is necessary to bend the waist excessively in order to lay the sheet from the bottom by laying down the sheet. Since the plate is transported in a large amount, There is a disadvantage in that the work efficiency is still lowered while being injured, and it is possible to prevent the object to be conveyed from being hindered when the partition member is installed. However, when the plate material or the like is conveyed, There is no fear that the plate material will be damaged and the plate material needs to be stacked up between the partition members so that the work efficiency is lowered rather than the transportation of the plate material by the existing transportation wagon having no partition member. It was not fit.

A technique for carrying various kinds of plate materials only has been developed as disclosed in Korean Patent Publication No. 25638 (published on Mar. 22, 2006), but it is hinged to a fixture to be fixed to and detached from an operator's belt, Since the sheet stretcher for carrying the sheet material can transport the sheet material more easily when the worker lifts the sheet material individually, it can not transfer a large distance in a large amount at a time. It is not possible to transfer the plate in a large quantity, and the plate can not be transported to the remote place.
