The following photos show Land Rovers being unloaded in Vietnam.
Although the photos show three different methods in use, one method has been undertaken in two slightly different ways.
Method #1 - Use of Lifting Platform
Method #2 - Use of Lifting Hooks
Method #3 - Use of Lifting Bars
This photo show the use of lifting bars placed under the front and rear springs. A rope each side between the two is used to keep the bars from spreading and dropping the Land Rover. The bar appears to be unprotected. With no protection, the Land Rover would most probably be adverse to moving around given that the bars would be made of steel. Bar appears to be flexing slightly and most probably made of solid steel or pipe.
The following photos show the same method in use but this time each bar has a considerable amount of protective material wrapped around it. I am not sure if this is to protect the Land Rover or to prevent the metal bar from sliding around on the springs or both. My suspicions point to stabilization rather than protection. For this method, the bar appears to be solid steel or square/rectangle hollow section.
