Description

The present invention relates to a transport jig used when a long heavy cargo having racks in front and rear in the traveling direction is transported with a forklift when transported.

When a heavy object having a circular cross-section such as a coil is placed on the carrier and transported, in order to prevent the heavy object from rolling on the carrier during transportation, in the gap formed between the carrier and the heavy object, For example, a detent made from wood or the like is installed (see, for example, Patent Document 1).

JP 2009-234608 A

Here, if a detent is placed in advance on the loading platform at the position of the gap formed between the loading platform and the heavy load, the detent is pressed against the loading platform by the heavy load placed on the loading platform and fixed. As a result, a heavy object can be loaded on the loading platform and transported immediately. Further, since the detent only touches the heavy object, the unloading can be started immediately after the heavy object arrives at the destination. However, since the detent is not fixed to the platform or heavy object, there is a high possibility that the detent will fall out of the gap between the platform and heavy object due to inertial force or vibration generated during transportation or deceleration. There is a problem.
On the other hand, when the detent is pushed into the gap between the loading platform and the heavy object and is fixed by the fixing member, the detent can be prevented from dropping during transportation or deceleration. However, since it takes time to mount the fixing member, it takes longer to load the heavy object on the loading platform and start transporting, and it takes time to remove the fixing member, so that the heavy object arrives at the destination. There is a problem that the time from unloading to completion of unloading becomes longer. In addition, when a work space for loading heavy objects on the loading platform and a work space for unloading heavy objects cannot be ensured, there is a problem that the time required for attaching and removing the fixing member is further increased.

The present invention has been made in view of such circumstances, and forklifts and long weights when transporting long heavy cargo having racks on the top and bottom in the direction of travel and having racks in the traveling direction with a forklift.
