An external ladder assembly for a nacelle of a wind turbine includes at least one ladder having parallel side legs and a plurality of rungs arranged between the parallel side legs. The ladder assembly also includes a ladder platform arranged with the ladder and configured for placement atop the nacelle. Further, the ladder assembly includes a mounting assembly for affixing the ladder platform atop the nacelle. More specifically, the mounting assembly is adjustable between multiple positions so as to level the ladder platform atop the nacelle. Thus, the ladder assembly provides access to one or more uptower, external features of the wind turbine.

The present disclosure relates to a safety screen comprising: a plurality of screen members vertically arranged above one another; two longitudinal carriers pivotally connected to the screen members, wherein in a first operating position, the longitudinal carriers extend vertically and the screen members extend horizontally, and wherein in a second operating position, the longitudinal carriers are inclined sideward from vertical and the screen members extend horizontally, offset from one another horizontally.

The present disclosure relates to a climbing shoe for a climbing safety screen, comprising: a support member for engaging a climbing rail of the climbing safety screen; a fork member with a first flange and a second flange; an outer member pivotally connected to the first flange and second flange about a transverse axis; an inner member mounted to the outer member and pivotable about a longitudinal axis with respect to the outer member.

Platform structures and platform assemblies are provided for supporting a plurality of radio frequency (RF) antennas and the weight of one or more workers. A platform assembly provided herein can comprise a pipe structure comprising at least one load pipe and at least one pipe segment, a first pipe segment of the at least one pipe segment connected to a first load pipe of the at least one load pipe, the pipe structure defining a circular pattern; a first radial beam extending radially inward from the pipe structure; and a platform structure supported by the first radial beam and the first load pipe.

Disclosed is a device for enabling an aircraft maintenance operator to access the exterior body of the aircraft. The device is adapted to be releasingly anchored to the fuselage of the aircraft. The device comprises a platform disposed above and transversely with respect to the fuselage and a pair of legs straddling the fuselage wherein, the platform extends between the pair of legs. Each leg comprises a leading means for leading the operator to reach the platform from the ground therethrough.

Platform structures and platform assemblies are provided for supporting a plurality of radio frequency (RF) antennas and the weight of one or more workers. One platform structure provided herein includes a steel radial beam extending from an RF tower and a plurality of steel arms welded to the radial beam. The platform structure also includes a first front plate having a front facing portion and an angled portion, where the front facing portion of the first front plate is welded to a first steel arm. Also included is a second front plate having a front facing portion and an angled portion, where the front facing portion of the second front plate is welded to a second steel arm. The platform structure further includes a first side plate having a side facing portion and an angled portion. The side facing portion of the first side plate is welded to a third steel arm. The platform structure also includes a second side plate having a side facing portion and an angled portion, where the side facing portion of the second side plate is welded to a fourth steel arm.

A maintenance device for maintaining an offshore wind turbine, the device being suitable for pressing against and traveling along the pylon of the wind turbine. The device includes a maintenance platform including a preferably U-shaped notch so that the pylon of the wind turbine can penetrate into said notch and travel means for causing the maintenance platform to travel along the pylon of the wind turbine. The travel means comprising a plurality of motor-driven crawlers arranged under said maintenance platform so that when the pylon of the wind turbine is placed in said notch with the vertical longitudinal axis of the pylon of the wind turbine perpendicular to the work plane of said maintenance platform.

An adjustable scaffolding that may adjust to the curvature of a structure. The adjustable scaffolding may comprise a main member, pegs, wing platforms, and rails. A method of use may be employed in which the main member is attached to a structure. The pegs may be secured to the main member in any desired orientation to adjust to the curvature of a structure. Wing platforms may be placed over the pegs, allowing a user to walk along the wing platform. Railing is placed within the pegs, allowing the pegs and the railing to secure the wing platform to the main member.

A method for demolishing a building, where the building comprises a building base placed in proximity of a ground, or placed on the ground, and an opposite building top or temporary building top arranged away from the building base, as well as building floors. The equipment used in the method includes a platform adapted to be positioned against the top of the building, avoiding ground support devices which extend from the platform to the base of the building or the ground surrounding the building. The platform includes at least one working scaffold adapted to be arranged along the periphery of the building and to face at least one floor of said building. The working scaffold is supported, hung, on the platform so that it descends along the side wall of the building to border the works for demolishing the building.
