An aerial work platform (AWP) includes a base, a retractable lifting mechanism, a platform, an actuator, and a spring. The retractable lifting mechanism has a first end rotatably coupled to the base. The platform is coupled to and supported by a second end of the retractable lifting mechanism. The actuator is pivotally coupled to the retractable lifting mechanism. The actuator has a piston received within a housing that is movable between a stowed position and a deployed position, where the piston engages and forces the retractable lifting mechanism away from the base to lift the platform away from the base. The spring biases the retractable lifting mechanism away from the base and provides a variable biasing force to the retractable lifting mechanism that increases as the piston approaches the stowed position.

The invention relates to a construction time elevator arrangement comprising a hoistway; a protection deck mounted within the hoistway for protecting the portion of the hoistway below it from falling objects; the protection deck comprising a roof member extending diagonally across the hoistway and covering the hoistway such that it blocks objects and/or water from falling into the hoistway below it; and a cross member extending in horizontal direction across the hoistway below the roof member. The cross member is pivotally connected with the roof member, the protection deck being collapsible into a transport state by pivoting the cross member and the roof member towards each other. The invention relates to a method implementing the construction time elevator arrangement.

A temporary platform for assembling elevator equipment in an elevator shaft is arranged substantially in the region of a shaft opening, such that the platform partially sits on a floor surface of the building and partially protrudes into the elevator shaft. The platform includes a bottom frame and bottom plates that lie on or are inserted into the bottom frame. The bottom frame also includes two lateral bottom bars, at least one front and one rear transverse bar that interconnect the two lateral bottom bars, and at least two intermediate bars that are arranged parallel to the two lateral bottom bars. The two intermediate bars are supported substantially by the front and the rear transverse bars.

A loading platform for use in building construction, the loading platform comprising a support structure adapted to be fixed to a building and extend outwardly from the building; and a deck mountable to the support structure such that the deck extends from the building, the support structure being configured such that at least a portion of an upper surface of the support structure extends level with or below a floor surface of the building when fixed to the building.

A furling crane loading platform (1) comprising: a cantilever support base (3); a first stage (2A) pivotally coupled to the cantilever support base (3); and a second stage (2B) pivotally coupled to first stage (2A). In an unfurled configuration (2B) the first and second stages provide a substantially horizontal crane loading surface extending from a building edge (11). The platform is configurable into furled configuration (2A). The platform may further comprise a third stage pivotally coupled to the second stage, fourth pivotally coupled to the third stage, hydraulic actuators (16), controller for controlling the stages in a sequence, sensor for sensing the configuration of the stages, detachable cantilever support beams (4) with a downward transition portion (19), props (5) to prop the cantilever support beams against an under surface of a floor slab and lockout mechanism (17).

A system for securing an air conditioning unit to a building without the need for any alteration and/or damage to the building itself. The system includes a cross bar, an air conditioning unit support, and a strut. The arrangement of the components results in the cross bar applying an outward force to an interior surface of the building and strut applying an inward force to an exterior surface of the building in response to the downward force exerted on the air conditioning unit support. The sum of the forces applied on the surfaces of the building is sufficient to secure the air conditioning unit to the building.
