An elevating cage system includes floor panels for a walk surface that can pivot upward to expose a portion of a container disposed below the platform. Each floor panel has a latch that pivots to engage a cage railing surrounding the platform and hold the floor panel in an open position. The latch is weighted about a pivot so that when the panel is pivoted to a completely open position, the latch pivots under its own weight to engage a stop so that the latch is disposed in an orientation to engage the handrail and hold the panel in the open position until an operator releases the latch. When the panel pivots to its closed position, the latch's weight balance about its pivot causes the latch to rotate until the latch engages the stop and is held in a stowed orientation in which the latch is entirely below a plane of an upper surface of the panel.

A mast climber, including a mast and a platform, is disclosed. The mast is comprised of at least two segments, including a bottom segment and one or more body segments. Each segment has a sidewall that is made of sheet metal, and most segments may be made of a lightweight metal, such as a aluminum. Each segment has at least one gear rail assembly, and may have two gear rails, disposed on opposite corners of the mast. A platform is adapted to be connected to the mast. The platform is equipped with a drive system that moves the platform up and down the mast. The drive system includes one or more electric motors on the platform and batteries to power the electric motors. Each motor has a gear that engages one of the gear rails. A backup power supply or generator may be provided.

It is an object of one or more embodiments of the present disclosure to provide a retractable mezzanine walkway, which when used in conjunction with high-density mobile shelving systems, expands and rolls out, creating an aisle for which employees can walk down. The retractable mezzanine walkway includes pairs of mobile shelving units configured to sit on top of parallel tracks. The retractable mezzanine walkway is configured to roll out between a pair of mobile shelving units when the pair of mobile shelving units is moved apart, such that an aisle is created, and configured to store inside the pair of mobile shelving units when the pair of mobile shelving units are moved together.

A plurality of sliding rails and a frame structure comprising a plurality of frame elements configured to be arranged at least partly circumferentially around a tower structure. Each frame element is slidably connected to at least one of the sliding rails, and the frame elements and the sliding rails are interconnected to form a scissor structure. An upwardly directed lifting force applied by a hoisting mechanism at connecting points at or near positions where the frame elements are connected to the sliding rails, in combination with gravity working on the frame structure, causes the frame elements to slide along the sliding rails, thereby causing the scissor structure to contract or expand to adjust a diameter of the frame structure to an outer diameter of the tower structure having the apparatus mounted thereon.

Self-climbing device for vertical and quasi-vertical concrete surfaces with main body equipped with a main beam by way of displacement rail, and several self-motorized frames, independent of each other and separately controllable, displaceable along the main beam of the main body, all with a characteristic operating method. The present invention provides the main advantage of allowing going up or climbing any structure, device or machine, such as a crane or a working platform, being applicable and usable on both vertical and quasi-vertical surfaces, flat or curved, free geometry and with variable slope, and with advances or displacements unit of variable length, adapted to the structure or area to climb.

A construction building equipment includes hanging pedestals, sleeve frames, hydraulic cylinders, upper reversing boxes, lower reversing boxes and track columns. The multiple hanging pedestals are fixed on an outer side of a shear wall of an external wall. The sleeve frames and the track columns are clamped on the hanging pedestals. The sleeve frames are clamped on outer sides of the track columns. The lower reversing boxes are fixed at upper ends of the sleeve frames. The hydraulic cylinders are connected with the upper reversing boxes and the lower reversing boxes. Side surfaces of the track columns are provided with pane holes for cooperative climbing of the upper reversing boxes and the lower reversing boxes. Upper ends of the track columns are fixedly connected with a top platform. Hangers and formworks are suspended on the top platform through booms.

An illustrative example embodiment of an elevator system includes a platform and a plurality of supports configured to selectively engage a nearby structure. The plurality of supports include at least a first support and a second support. The first and second supports alternate between engaging the nearby structure to support the platform while the other one of the supports is disengaged from the nearby structure. At least one of the first and second supports is configured to move relative to the platform while engaging the nearby structure to cause vertical movement of the platform.

An anchor for self-climbing structure of the type used on vertical or near-vertical concrete surfaces that uses metal inserts in the precast concrete tower and interlocking spikes in the self-climbing structure that are provided with rotary and rocking movement is disclosed. The anchor affords the main advantage of minimising tensile and shear loads on the concrete of the tower with maximum contact and optimum load distribution, while also achieving self-correction of possible coupling positioning and alignment errors. All of this results in improved delivery and distribution of the loads from the climbing device to the concrete wall and general structure that allows larger sized loads to be lifted and withstood than existing devices.

An automated building washing device generally includes one or more rotational brushes having a vertical rotational axis coupled to a window washing swing stage. The brushes are horizontally movable from end-to-end along the longitudinal direction of a window washing swing stage while rotating about their vertical axis so that a relatively large portion of building surface can be quickly cleaned.

A plank scaffold system and, more particularly, to a ladder-based vertically-adjustable plank scaffold system. The system may have a pair of ladders, a wall standoff mounted at the top of each of the ladders, a crane support mounted at the top of each of the ladders, a vertical guide bar and roller system to keep it from swinging on the cables, and a horizontal platform suspended on cables below the crane supports, the platform having a pair of cable winches mounted thereon for varying the elevation of the platform. Instead of ladders, tower scaffolds or stage towers may be used on each side to support the vertically-adjustable plank.
