A height adjustable platform assembly securable to a building including a pair of anchors each removably mountable to the building through an opening thereof at a respective one of the opening lateral edges; a pair of supports each removably mounted to a respective one of the anchors; and a platform positionable so as to extend between the supports and be supported thereby. With the height adjustable platform assembly operatively secured to the building with the anchors mounted through the building opening, the supports each protrude outwardly from the building and support the platform outside of the building adjacent to the building outside surface. Each support is mountable to the respective one of the anchors at at least two vertically spaced apart locations therealong to allow adjustment of a vertical position of the platform relative to the building.

A scaffolding to be fastened to a bridge or the like deck structure comprises a boom system (2) for supporting the working platforms and the support structures needed for the work and for fastening the boom system of the fastening body (1) to the upper surface of the deck structure. The boom system (2) is connected to the fastening body via a swivel quadrangle (3, 6, 11, 12).

Climbing equipment for the construction of a building, including at least one scaffold that at least partially surrounds the perimeter of a building floor and is provided with a walkable surface. The climbing equipment includes a traction device comprising at least a first portion integral with the scaffold, and at least a second portion connected to the first portion. The first portion includes a first coupling element adapted to grip a first coupling portion of the building, and the second portion includes a second coupling element, arranged at a different level than the first coupling element, and adapted to grip a second coupling portion of the building. The climbing equipment further comprises a moving system. When the first coupling element is released from the respective coupling portion, the moving system performs a relative movement between the first portion and said second portion of the traction device, so as to move the scaffold by a predetermined amount.

A load carrying platform shuttle (10) has a static frame (12) and a movable carriage (14). The frame is securable to a mounting location, such as a given working level of a multi-storey building under construction, and the carriage is arranged to telescope into the static frame between an extended position outboard of the mounting location and a retracted position inboard of the mounting location. The movable carriage can move between the extended position and the retracted position while carrying a load. The shuttle includes a motor (76) and gear assembly (72, 74, 78) for driving the movement of the carriage between the extended position and the retracted position while carrying the load.

A falling prevention structure can be stably connected to an attached lift scaffold body and is provided with a hinge point in the middle. The control arm is on one side of the hinge point, and an extension portion of the control arm can be connected/matched with a lifting structure of the attached lift scaffold. An operating arm is on the other side of the hinge point, an extension portion of the operating arm is provided with a transition structure and connected to a falling prevention pin by the transition structure. The falling prevention pin is provided with an elastic restoring structure and is capable of extending and retracting, and the extending falling prevention pin can be inserted into a clamping and hanging structure in a falling prevention structure directly or indirectly fixed to a building object.

A traveling step structure is mounted to a warehouse rack to allow convenient access to elevated shelves without blocking shelving corridors. A rack track is mounted to a rack between vertical rack members and a support track is fixed to the surface which supports the rack. The traveling step structure has a first frame mounted with followers to the rack track, and a second frame positioned outwardly from the first frame, and connected to the first frame for movement from a retracted position to an extended position. A plurality of steps extend between the first frame and the second frame and are pivotably mounted to both frames. When a user desires to access an elevated rack shelf, the second frame is pulled outwardly and downwardly to bring the steps into a horizontal position. A damper assembly is mounted between the first frame and a step to cushion extension.

Methods of performing assembly or maintenance on an aircraft, systems for performing desired assembly or maintenance on an aircraft, and mobile work stations useful for such systems and methods, where the mobile work stations include a work platform, including an accessway providing access to the work platform; and a moveable base supporting the work platform with one or more platform jacks that can adjustably raise and lower the work platform.
