[0010]

A load skid device according to a first aspect of the present invention comprises a movable skid which is held at a position separated from a load by a height of a load to be stacked in a lower layer, and the movable skid which is loaded on the movable skid. And a drive unit for moving between at least two positions, that is, a position where the vehicle is to be loaded and a position where the cargo is evacuated when the cargo is loaded thereunder. When an operator or the like issues a command via the operation unit, the operator is moved to a position corresponding to the command.

In other words, according to this loading skid device, even if there are no two workers, the movable skid can be moved to the position where the cargo is loaded by simply issuing a command to the driving unit via the operation unit, and (Hereinafter referred to as a retreat position), thereby saving labor.

Since the load to be loaded is limited by only one movable skid as a rod-shaped member, a plurality of movable skids are provided, and when the load is placed on these, the load is suitable for the size of the load. It may be advantageous to place them in parallel at spaced intervals, or to provide another carrier skid device on the carrier to support the load in cooperation with its movable skid.

The movable skid may be moved by the drive unit by a parallel movement or by rotating the carriage about a left-right axis of the carrier. However, in the latter case, if the retractable position of the movable skid is set near the upper surface of the loading platform, it is necessary to lift the movable skid until the movable skid reaches a height at which the cargo can be loaded. Even if the evacuation position is set to another position,
It is necessary to lift it somewhere, which increases the output required for the drive unit.

In this respect, in the skid device according to the second aspect, the movable skid is supported so as to be rotatable about a vertical axis, and the driving unit rotates the movable skid about the vertical axis by at least 90 degrees. It is made to rotate. Then, the load is placed on the movable skid at any of the rotation positions, and the position where the movable skid is rotated by 90 degrees from the load is set as the retreat position.

[0015] Specifically, for example, a state in which the movable skid is parallel to the width direction of the carrier is defined as a position on which the cargo is loaded,
A position rotated 90 degrees therefrom, that is, a position parallel to the length direction of the loading platform may be set as the retreat position. In this case, since the drive section only needs to rotate the movable skid about the vertical axis, there is no need to lift the movable skid, and the output of the drive section can be reduced.

According to a third aspect of the present invention, there is provided a loading skid device.
A carrier fixing portion for detachably fixing the carrier skid device to the carrier is provided. According to this loading skid device, the loading work on the truck can be saved by loading the loading skid device on a truck or the like where the cargo is to be loaded on two or more layers.

According to the fourth aspect of the present invention, the movable skid is fixed to the drive shaft so as to be movable downward by the weight of the loaded cargo. This amount of movement is, of course, within a range that does not damage the cargo loaded under the movable skid.

A movable skid support is provided for supporting at least the end of the movable skid from below when the movable skid moves downward. Therefore, according to the loading skid device of the fourth aspect, even when a heavy load is placed, the moment applied to the vertical axis can be suppressed,
This allows even heavier loads to be loaded.
