JACKING DEVICE Abstract of the Disclosure This disclosure relates to a jacking or lifting device for use with trailers or the like. The jacking device of the present invention is basically a two-piece structure comprised of a rough adjusting column which is spaced apart from and externally secured to the outside cylinder or housing of an otherwise conventional lifting jack. With this new construction, only relatively simple adjustments need to be made on the rough adjusting column, to enable the jacking device of the present invention to cover a wide range of lifting heights with minimum effort.
