An automatic wall adhesion and cleaning system includes a cleaning mechanism for cleaning the outer wall of a building, and a vacuum-based wall adhesion mechanism adherable to the outer wall of the building by a vacuum suction force and adapted for carrying and moving the cleaning mechanism on the outer wall of the building. Thus, the automatic wall adhesion and cleaning system can save labor cost and eliminate the risk of human life due to rupture of the ropes of a hanging cage.

A disassembled wind turbine under repair includes a tower secured to a foundation and a nacelle mounted atop the tower. The nacelle includes a base wall, side walls, a front wall, a rear wall, and a top wall. The front wall includes an opening configured to receive a main shaft of the wind turbine; however, the main shaft and a rotor of the wind turbine have been removed from the nacelle during a repair procedure. As such, the disassembled wind turbine further includes an external platform assembly secured at the opening of the front wall of the nacelle during the repair procedure.

A scaffold toeboard system for locking a toeboard between two vertical scaffold members where each vertical scaffold member includes a tubular member having a diameter and an outer shape. The toeboard system includes a toeboard having an elongated member with a fixed terminating end and an adjustable terminating end. The toeboard further includes a front portion, a top portion, a bottom portion and a rear portion. The toeboard system further includes a locking mechanism slidably mounted to the adjustable terminating end, where the locking mechanism includes a lock member body with a front sidewall two fingers positioned on said locking mechanism and extending outwardly from the front sidewall of the locking member. The two fingers separated by a horizontal distance of about the diameter of a scaffold vertical member. The locking mechanism further includes a lock, where the lock is actuatable to fix the position of the lock member body with respect to the toeboard in a deployed position. The fixed terminating end is shaped to engage a scaffold vertical member.

A method of constructing a structure in which an item is to be installed at an elevated height on the structure. Hoists are hung from the structure. A platform is moved from ground level and positioned at a first elevated position between ground level and the hoists. The platform is attached to the hoists at the first elevated position. After the platform has been attached to the hoists, the item is moved onto the platform. The item is lifted on the platform to a second elevated position for installation at the elevated height on the structure and the item is installed at the elevated height.

A system for a climbing apparatus including a housing assembly, a wheel assembly, a lock assembly, a rope assembly and a chainsaw assembly is disclosed. The housing assembly includes a housing having a rope wheel therein. The housing is mounted to a chainsaw to power the components within the housing to allow a user to ascend and descend a structure. The rope is secured to the top of a structure and then mounted to the rope wheel at an opposite end. The chainsaw is actuated to also actuate rope assembly. The rope wheel rotates to allow for rope to be fed, allowing a user attached to the housing to ascend or descend, as needed. With the lever the user may lock the rope in place to allow the user to work at a desired height on a structure.

A hoist elevator control system and a hoist elevator for a multi-story building structure on a building site, comprises an enclosure for raising and lowering personnel and materials. The control system comprises a sensor external to the enclosure, a sensor internal to the enclosure, a call button at each floor, and a processor located within the enclosure. The processor obtains data from the sensors and the call buttons and provides output to a display screen in the enclosure and to an external control location. The internal sensor may be a people counter that issues an alarm to prevent operation when the enclosure has more than a preset number of people within. The people counter may send the current number of people within to the processor for processing, and data may allow an operator to control the elevator, for example via a cloud connection and/or a telephone application.
