This solution is for washing and cleaning the external walls of a building, and adopts a lightweight six axis robotic arm mounted on a mini-gondola hoisted by a pulley system with the controlling motor located within the mini-gondola, while another set of motor located on the pulley system at the roof-top end drives the mini-gondola to traverse laterally on a set of twin-rails on the roof-top of the building. Four vacuum suction cups mounted on the minigondola through linear actuator are used to secure the mini-gondola to the wall. Each linear actuator has three ultrasonic distance sensors that measure and manage the distance between the mini-gondola and the wall to be cleaned. Once the gondola is in position, the robotic arm will be activated to start the cleaning process.

A suspended scaffold assembly for mounting a scaffold. The suspended scaffold assembly comprises a plurality of horizontally-spaced-apart vertical support members comprising a suspension cable with at least one coupling ring secured thereto and at least one horizontal member. Each one of the at least one horizontal member is removably connectable to a respective one of the at least one coupling ring of two spaced-apart ones of the plurality of vertical support members. A vertical support member for a suspended scaffold assembly, a kit for mounting a suspended scaffold assembly and a method for mounting same are also provided.

A demolishing method utilizes an aggregate stack demolishing scaffold apparatus mounted to an upper part of an aggregate stack including four smoke funnels arranged adjacent to each other. An uneven scaffold including one plate-shaped upper scaffold portion is placed on an upper end of each smoke funnel. A lower scaffold portion is coupled to the upper scaffold portion and located in lower positions in the smoke funnels with the upper scaffold portion being placed on the upper ends of the smoke funnels. A chain block suspends and supports the uneven scaffold from and on an inner wall of each smoke funnel, and adjusts a suspending height. With this configuration, the upper scaffold portion is located on the upper ends of the smoke funnels, and thus there is no possibility of contact between the scaffolds in the smoke funnels causing a worker to lose his balance, thereby improving safety.

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.

A facade gantry allows for close inspection of a facade using remotely operated cameras, probes, and/or sampling devices. These devices are located in a housing that is positioned in front of a facade by a system of cables, from which it is suspended, that allow for movement in any direction in a plane. Two cables are attached to the housing containing the sensors and tools and are wound onto two separate spools located on the roof at the vertical boundaries of the inspection area. By winding and unwinding these spools, the housing can be raised, lowered, and moved from side to side. The invention further has an optional “shed” located on the ground that protects pedestrians in the case of a suspension system failure. The shed moves to maintain a position directly under the housing. The gantry optionally allows for repair of the facade by using remotely operated repair tools.
