Document Type and Number:

Japanese Patent JP7222646

Kind Code:

B2

Abstract:

To prevent floating of a swing frame (hence, load platform) as a result of lengthening of a raising/lowering cylinder due to external force received in the process of unloading or loading in a transport vehicle designed such that the front part of the load platform is engaged with the top of a swing frame, pivotally supported on the rear part of a vehicle body, so as to be movable forward and backward, the swing frame is allowed to erect and swing together with the load platform by means of the raising/lowering cylinder, and the load platform can be driven between the furthest backward inclined position where the rear end of the load platform is in contact with the ground and the furthest forward loading position on the top of the swing frame in a lowered position.SOLUTION: A hydraulic controller C that exerts feed/discharge control for hydraulic oil pressure for a raising/lowering cylinder Cc exerts the feed/discharge control to maintain a shortened state of the raising/lowering cylinder Cc during an unloading process in which a load platform 3 is driven from the furthest forward loading position 3F to the furthest backward inclining position 3R, during loading process in which the load platform 3 is driven from the furthest backward inclining position 3R to the furthest forward loading position 3F, or during the unloading process and the loading process.SELECTED DRAWING: Figure 14
