A ceiling ladder having a plurality of sections that can be climbed by a user when in an unfolded position into an attic and that can be folded together into a retracted position to be stored above the ceiling. The ladder has a deep step, which has a width greater than the width of other steps of the ladder, in which is located between about 2-5 feet from the floor when the ladder is in the unfolded position so user can stand on the deep step in place objects into the attic without having to climb into the attic. A deep step for a ceiling ladder.

A folding stepstool which can be folded into a shape which enables the folding stepstool to be carried easily. In a folding stepstool, a front leg and a rear leg can be housed in a recess-shaped first space in the lower surface of a first top board, and a front leg and a rear leg can be housed in a recess-shaped second space in the lower surface of a second top board. Further, when the top plates are closed, the two front legs and the two rear legs can be housed in the internal spaces in the top plates in a closed state.

Platform systems can support a user at an elevated position while being drivable or mobile via wheels and a drive system. Rail assemblies can be folded or collapsed so that the platform system can be carried by a user from one location to another. Hand controls are operable by the user from the elevated position to move the platform systems across a ground surface and can have automatic braking capability. Each side of the platform system can be independently driven, thereby allowing zero point turning and other fine control maneuvers. Structures at the base of the platform system can limit or prevent tipping or tilting. A cage system can help keep a user on the platform(s). Platforms can be collapsed or stowed with the rest of the platform system.

A step stool includes a step frame including a plurality of legs and a handrail coupled to the step frame. The step frame is foldable so as to assume a flat profile for storage. The handrail is mounted on the step frame and is movable relative to the step frame. The handrail provides support for a user standing on the step frame.

An elevator car includes a car floor; a movable ceiling, which is pivotable between a normal operating position, in which the movable ceiling extends substantially horizontally and a maintenance position, in which the movable ceiling extends into an interior space of the elevator car; a working platform movably attached to the movable ceiling. The working platform is pivotable between a storage position, in which the working platform extends basically parallel to the movable ceiling, and a working position, in which the working platform extends transversely from the movable ceiling; and at least one foldable leg attached to the working platform. The at least one foldable leg is foldable between a storage configuration, in which the at least one foldable leg extends substantially parallel to the working platform, and a working configuration, in which the at least one foldable leg extends transversely from the working platform for supporting the working platform.

A lifting positioning structure for a ladder tool platform comprises a ladder. The ladder comprises front supporting legs, rear supporting legs, connectors fixedly connected to the front supporting legs, plug pins, and elastic parts, wherein each front supporting leg includes a big tube and a small tube which are able to relatively move in an extension direction. The connectors are formed with vertically-through installation cavities which allow the big tubes to be inserted therein. The big tubes are arranged in the installation cavities and are fixedly connected to the connectors which extend to form connection parts rotationally connected to the rear supporting legs. The small tubes are connected to a tool platform. The plug pins are movably arranged on the connectors or the big tubes.

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.
