I would like to know if it is possible to use the weight of a loaded truck to unload it, and if so by what kind of mechanism.
Imagine a truck loaded with a shipping container.
A "fork" (as in forklift but without the lift) is inserted in holes between the truck trailer and the container. The truck parks on a special platform. This platform is now "unlocked" so that it gets depressed by the weight of the truck. The fork with the container now rests on "stools" (I don't find the appropriate English word) on each side of the truck. The truck has now been unloaded with no consumption of energy, and can drive off.
Later an unloaded truck reverses in under the container which rests on the fork which in turn rests on the "stools" on both sides. Now the stools are "unlocked" so that the weight of the container pushes down until it rests on the truck trailer. Again, no energy has been consumed. The fork can be removed and the truck drive off loaded.
The platform and the "stools" can be raised when unloaded, which could be done with quite little energy. Possibly by manual labor.
I wonder what kind of mechanism would be suitable for the "depression" movement under the heavy load of the container and truck. Hydraulic or counter weight or screws or what? I also wonder what concepts could be useful for the "locking and unlocking" mechanism? The parking of the truck between the "stools" should take place in locked mode, without vertical movements.
The bakground is a vague idea for an inland cargo terminal in a developing country. Trucks can only take one container each to and from a seaport because of steep mountains just inside the coastline. If containers could be reloaded on the other side of the mountains, then each truck could take two (or even three on trailers with enough space) containers for the thousands of kilometers of flat roads in the vast inland. THis would drastically reduce the soaring fuel costs. Since the economy is severly depressed, traffic is low and so there is little need for speedy reloading. Also, low cost is extremely important. The use of forklifts (and the large paved areas they require for manouvering) would be too expensive. Especially investment costs must be kept at a minimum since the probability of total loss is high due to the corrupt government. An attractive piece of equipment such as a forklift is very likely to get stolen (by the police!)
