An access platform system for enabling access to and from ground-based structures, vehicles, and mobile equipment. The system has a main frame that is attached to or juxtaposed with one or more of 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 a multi-stage apparatus for influencing the stroke of lift cylinders. In one embodiment, the folding steps assembly has folding and unfolding steps.

A folding leg for a stepladder is disclosed. The folding leg allows the width of the stepladder base to be narrowed when in the stored orientation and widened while in an in-use orientation.

A cabinet mounted step stool can be collapsed to a narrow horizontal profile for storage without compromising usefulness of the cabinet. The step stool is supported on support channels fastened to two side walls of the cabinet. A pair of fixed track channels are supported on the support channels with the fixed track channel openings facing each other, within which two sliding track channels slide with one on the left and the other on the right. Four step support assemblies, each of which comprises a step support with one end pivotally attached to a roller and the other end pivotally attached to a foot. Two rollers slide within the left and other two rollers slide within the right sliding track channel. Two steps are supported on four corners by the four step support assemblies. When extended, the step stool provides two steps with approximately 13½″ rise in height.

A foldable stepladder in accordance with the present disclosure may be changed by a user from an expanded use mode to a collapsed storage mode. The foldable stepladder includes a handrail that moves to reduce the overall height of the stepladder when in the collapsed storage mode.

A step unit including a vertical frame and a plurality of linkages pivotally attached at different heights to the vertical frame by one end of each of the linkages, to provide lateral rotation to the linkages. A leg frame, with at least one leg, is pivotally attached to the opposite end of each linkage whereby laterally translating the leg frame simultaneously pivots the linkages from a first, vertical position to at least one second, horizontal position.

A ladder having a first rail having a bottom and a web, a first flange attached to a first end of the web and a second flange attached to a second end of the web. The ladder having a second rail. The ladder having rungs attached to the first rail and second rail upon which a user steps to climb the ladder. The ladder having a foot having a plastic body with a recess which receives the end of the first rail and is positioned about and conforms to the web and the first and second flanges of the first rail. The foot has a plastic base having a top side from which the body extends. The base has an edge positioned about the body with perforations, and a rubber tread disposed along a underside of the base and extending through the perforations and along the edge on the top side of the base to form an overmolded portion of the tread that attaches the tread to the base without any mechanical or other types of fasteners. The rubber tread forms a bond with the underside of the base and the edge on the top side of the base. The foot for a bottom of a rail of a ladder. A method for placing a ladder. A method for producing a foot for a bottom of a rail of a ladder.
