Description

[Detailed description of the invention]

[0001]

The present invention relates to a propane gas cylinder,
Also, the present invention relates to a cylinder loading / unloading apparatus which can easily load and unload a transport vehicle such as an oxygen cylinder.

[0002]

2. Description of the Related Art Conventionally, when transporting propane gas cylinders or oxygen cylinders, place the cylinders on a shipping platform installed at the height of the cargo platform of the vehicle. Loading was taking place. When the cylinder is lowered from the loading platform, the cylinder is lowered to the ground by human power and a lifting lift provided on the leak side behind the loading platform.

[0003]

However, in the above-mentioned conventional example, when a large number of cylinders are loaded on a carrier, much labor is required and the work efficiency is reduced.

[0004] In addition, since the loading state of the cylinder placed on the loading platform is unstable, the cylinder may fall due to the shaking of the vehicle, which is dangerous. Also, in order to load the cylinders horizontally, they must be placed vertically before transporting by turning the cylinders. For this reason, the operator has required a lot of labor to place the cylinder vertically.

[0005] In addition, when the place for unloading the cylinder is small, the work is particularly difficult.

[0006]
