Abstract: An elevated platform system includes first and second platform sections and a ladder for accessing the platform sections in an elevated position. The platform sections are aligned in longitudinal arrangement and are configured to be selectively disposed and coupled between a pair of mobile storage units. The first platform section has a proximal end portion defining an opening for receiving a ladder hook. A distal end of the first platform section can releasably couple to a proximal end portion of the second platform section. The platform sections are movable between a deployed or installed position in which they secure the first and second storage units to form an elevated walking or standing surface therebetween, and a retracted or uninstalled position in which the platform sections are detached from at least one of the mobile storage units the allow relative movement of the storage units.

Abstract: A ground rod and guy stake extractor according to the present approach overcomes many deficiencies of contemporary methods, and allows for the rapid extraction of ground rods and guy stakes across a full range of environments, and at a wide range of extraction angles, with a straight pull on the item being extracted. Embodiments may be lightweight, easily transported, and operated by a single individual. Embodiments may include a winch, winch cable system, and support structure. The geometry is such that it is easy and straight forward to align the direction of pull with any rod or ground stake, and particularly for those driven into the ground within the commonly prescribed angular limits, thus assuring a continuous, steady pull of at least four feet in most embodiments. Guy stakes can therefore be easily extracted in one step, and typically ground rods (because of their length) in two steps.

Abstract: A wheel and bracket device that is removably attachable to a ladder. The present invention allows users to more conveniently transport a ladder, ladder tree stand, or other such device, along with objects that may be supported thereon. The present invention is a bracket that is adapted to enclose a rail and a rung of a ladder and be securely affixed to the ladder via a locking mechanism, such as a locking pin. A wheel is rotatably attached to the bracket, thereby allowing users to push or pull the ladder across terrain, rather than being forced to carry the ladder.
