ABSTRACT:
A leveling device for heavy structures such as mobile homes. A ramp forms a base having an inclined ramp surface covered by a metal plate provided with two columns of grooves. A wedge shaped walker has an inclined surface which mates with the ramp surface and a platform surface which is level when the inclined surfaces are engaged. Two columns of teeth are formed on a metal plate on the inclined surface of the walker to enter the grooves in a manner to lock the walker in place. Lateral guide rails prevent side to side movement of the walker and maintain the alignment of the teeth and grooves.
