Description

Detailed Description of the Invention

The present invention relates to a manual crane for a light truck that can be attached to and detached from a torii of a light truck and can perform a work of loading and unloading luggage.

2. Description of the Related Art Conventionally, there is a simple crane that can be easily installed to load and unload a light truck.
Such a simple crane is installed at the front part in the loading platform of the light truck, and has a base part provided with a fixing means for directly fixing to a torii of the light truck or a wall arranged behind the cab, A shaft body provided on the base portion and capable of turning around a vertical axis, a boom provided at an upper end of the shaft body and rotatable in the vertical direction around the tip of the shaft body, and a substantially intermediate portion of the boom And a support erected in a substantially middle part of the shaft body.
The shaft body is provided with a height adjusting means in which a lower end and a substantially intermediate portion are attached to the base portion so as to be rotatable around a vertical axis, and the height can be set at an arbitrary position (see Patent Document 1).
JP 2008-273736

However, since the base portion of the simple crane is installed in the light truck bed, the load capacity from the light truck bed to the height of the cage is eroded.

A manual crane for a light truck according to the present invention has been made to solve the above-mentioned problems, and a vertical rotation shaft attached to a torii located above the upper end of a tilt, and an upper end portion of the vertical rotation shaft. A boom mounted on one horizontal rotating shaft, a base end portion mounted on the lower end portion of the vertical rotating shaft with a second horizontal rotating shaft, and a tip end portion detachably mounted on the boom with a plurality of third horizontal rotating shafts; It is characterized by comprising more.

According to the present invention, by attaching the light truck manual crane to the torii located above the upper end of the tilt, the load capacity from the loading platform to the upper end of the tilt is not eroded.

Next, an embodiment of the present invention will be described by way of example with reference to the drawings.
First, the structure of the manual crane for light trucks is demonstrated.
As shown in FIG. 1, the manual crane for a light truck has a vertical rotating shaft 3 attached to a torii 1 installed above a cage 10 with a bearing 2, and a first horizontal shaft at an upper end of the vertical rotating shaft 3. The boom 6 attached by the rotary shaft 4 and the base end portion are attached to the lower end portion of the vertical rotary shaft 3 by the second horizontal rotary shaft 5, and the tip portion can be attached to and detached from the boom by the plurality of third horizontal rotary shafts 8 and 9. It is comprised from the support 7 attached to.

Next, the usage method of the manual crane for light trucks is demonstrated.
As shown in FIG. 2, the support 7 attached to the third horizontal rotation shaft 8 is attached to the third horizontal rotation shaft 9, and the boom 6 is turned to the outside of the loading platform 11. A lifting machine 13 such as a chain block is attached to the hook 12 at the tip of the boom 6 to lift a load or the like, and the boom 6 is turned inside the loading platform 11 and suspended from the loading platform.

As a result, the loading volume from the loading platform to the upper end of the tilt is not eroded.
