Unloadinq Machine This invention relates to an unloading machine to unload heavy ore material like coal, cement or iron ore transported by a flat car or a rail freight car from a mine or port.
Known in the prior art are forklifts and fork-machines with rotating freight (so called `rotating dump') cars. These are usually manually operated and are very expensive and costly to maintain.
Furthermore, they can only be used in cooperation with a limited range of freight car sizes. They cannot cope with various sizes of freight cars or all kinds of cargo material.
In particular, when the cargo is frozen in winter, it takes too much labour to unload and other trailers are needed to meet freight cars with a fixed machine on site.
An object of the present invention is to provide a newly contrived unloading machine to cope with the above mentioned problems and one that can trail freight cars without the aid of another trailing car.
It is another object of this invention to provide an unloading machine that can easily unload frozen cargo or cargo that is stuck to the wall of a car.
