Description

  The present invention relates to a work vehicle in which a floor plate for receiving an outrigger float is stored in a vehicle portion.

When trying to install an outrigger for a work vehicle at a work site, a floor plate that catches the outrigger float is often used.
The laying board is laid directly on the ground for the purpose of curing the ground on which the outrigger float contacts the ground, and a metal (iron, aluminum) board having an area several times larger than the outrigger float is used.

  In addition, there is a board that is interposed between the above-mentioned floor board and the outrigger float, and is used for the purpose of adjusting the height of the outrigger float. This type of slat has a slightly larger area than the outrigger float, is thicker than the metal slat described above, and is often made of wood or resin. This type of floorboard is sometimes called a bangi.

Since it is necessary to always provide such a floor plate required for the outrigger operation in the work vehicle, various floor plate storage devices that are equipped in the work vehicle have been proposed.
For example, it is arranged between the front wheel and the front outrigger on the front left and right sides of the carrier frame of the wheel crane, and between the rear wheel and the rear outrigger on the left and right sides of the rear, and stores the floorboard one by one in a vertical posture. A floorboard storage device has been proposed (Patent Document 1).

In addition, a floorboard storage device has been proposed that is disposed in a space located between a step attached to a vehicle unit and a vehicle frame, and that allows the floorboard to be taken in and out in a horizontal direction (Patent Document 2).
In addition, a floorboard storage device using a space below a boom in a retracted state, which is a front upper region of a vehicle frame, has been proposed (Patent Document 3).
