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.

Service platforms are provided for accessing the collapsing frame of blown film extrusion apparatus. The service platforms provide an access platform capable of being placed proximate the collapsing frame of the blown film extrusion apparatus to allow for service, maintenance and/or cleaning of the apparatus.

A platform system includes a support structure of variable length; a platform mountable on the support structure; and a plurality of platform supports for supporting the platform. At least one of the platform supports is slideably mounted on the support structure such that it is slideable with respect to the support structure. At least one of the platform supports includes a spacing element, which extends between that platform support and an adjacent one of the platform supports and engages the adjacent platform support, such that the maximum spacing between those platform supports is limited by the spacing element.

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 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 hydraulic arrangement. The hydraulic arrangement has multiple hydraulic units, the control units of which are connected, in particular in series, via a data connection. The control units are preferably designed to control selectively only hydraulic cylinders directly associated with said units, or also indirectly control, via the data connection and the control unit of an additional hydraulic unit, the hydraulic cylinders associated with said additional hydraulic unit. A climbing formwork having at least one climbing unit, in particular multiple climbing units. The hydraulic units can be linked via the data connection such that synchronous lifting and/or lowering of all climbing units can be or is achieved. The hydraulic units are preferably connected in a master-slave arrangement or are preferably controlled in a master-slave mode. Also preferably, the hydraulic units are designed to switch from the master-slave mode to the stand-alone mode.

The self-climbing installation platform comprises two decks positioned upon each other. Each deck comprises guide means supporting the deck movably on guide rails and locking means locking and unlocking the deck to the guide rails and/or to guide rail fixing means. Lifting means move the two decks along the guide rails in relation to each other. At least one power source provides power to the lifting means. The installation platform climbs stepwise along the guide rails by alternatingly locking and unlocking the lower and the upper deck to the guide rails and/or to the guide rail fixing means and thereafter raising the unlocked deck.

The invention relates to a movable machine room comprising a support platform of a hoisting machine, the support platform comprising one or more releasable mounting mechanisms for releasably mounting the moveable machine room in a hoistway, and a hoisting machine mounted on the support platform; a working platform on top of the support platform, preferably forming a roof of the moveable machine room and/or comprising handrails; and at least one support structure supported by which the working platform rests on the support platform; and wherein each said support structure is selectively actuatable to expand in vertical direction for hoisting the working platform higher above the support platform taking reaction force from the support platform, or to contract in vertical direction for lowering the working platform back towards the support platform. The invention relates to an arrangement and a method implementing the movable machine room.
