An access platform system for enabling access to and from ground-based structures, vehicles, and mobile equipment. The system has a main frame with walls that is attached to or juxtaposed with the ground-based structures, vehicles, and mobile equipment; a vertical platform displacement assembly attached to the main frame; and a folding steps assembly. The vertical displacement mechanism has left and right intermediate carriage assemblies, and left and right lift cylinders with a multi-stage apparatus for influencing the stroke of the lift cylinders. In one embodiment, the folding steps assembly has an electromechanical means for folding and unfolding the steps.

A portable ladder platform attachment, for increasing a person's safety when standing on a ladder, includes a platform having a surface, a forward edge, a rear edge, and opposing side edges, and a rod having a serpentine shape confined within a vertical plane above a centerline extending between the forward and rear edges of the platform. The rod has a first end coupled to the platform closer to the forward edge than to the rear edge, a midsection that extends above and substantially parallel to the surface of the platform along the centerline, and a second end shaped as a hook sized to fit closely about an upper rung of the ladder while the platform sits on a lower rung of the ladder.

A tool holder support structure is disclosed that may include a longitudinal support portion extending between a first end and a second end; a first brace connected to the first end, and a second brace slidably connected to the longitudinal support portion. The tool holder may include at least one threaded rod with at least one clamp surface, and a tool holder base connected to the longitudinal support portion, the tool holder base may include a tool holder opening for receiving a tool holder.
