An apparatus includes a ladder assembly configured to be used with a vertically-extending wall assembly of a building having a window assembly installed to the vertically-extending wall assembly. The ladder assembly includes a housing assembly configured to be fixedly received (at least in part) in the vertically-extending wall assembly, to be mounted to the vertically-extending wall assembly, and to extend (at least in part) into the vertically-extending wall assembly of the building. A support assembly is configured to be fixedly attached to the housing assembly, and to extend (at least in part) into the housing assembly in such a way that the support assembly bisects the housing assembly. The support assembly, in use, provides any one of a handhold and a foothold configured for usage by a user.

A wind-power-installation tower segment, a wind-power-installation tower, a wind power installation, a use of a holding arrangement, a use of a first transport device and of a second transport device, and to methods for assembling a wind-power-installation tower segment and for assembling a wind-power-installation tower section. In particular, a wind-power-installation tower segment for a wind-power-installation tower, comprising a shell segment, having an extent in the direction of a segment height, a segment ring direction and a segment thickness, and an upper horizontal abutment side and a lower horizontal abutment side, a holding device for arranging requisites inside a wind-power-installation tower segment, having a main section, and at least one projecting section, wherein the main section and the at least one projecting section are arranged adjacently to each other in the segment ring direction, wherein the main section and the at least one projecting section enclose a holding-device angle, a coupling device, which is arranged in a coupling section of the shell segment, adjoining the upper horizontal abutment side, wherein the holding device is coupled to the shell segment by means of the coupling device.

A ladder support attachment for spacing a ladder from a structure having a support member configured to mount to the structure and stabilizing the ladder; a spacing member integrally coupled to and extending outwardly from an upper edge of the support member; and a trough member integrally coupled to a distal edge of the spacing member and configured to receive a rung of the ladder. The trough member having a first planer member coupled to a distal edge of the spacing member at an acute angle relative to the support member, a second planer member coupled to a portion of a distal edge of the first planer member and extending transverse to the first planer member, and a third planer member being coupled to a distal edge of the second planer member and extending transverse to the first planer member.

A multirotor wind turbine (1) comprising a vertical tower and at least two energy generating units (5), a load carrying structure (9, 10) extending transverse to the vertical direction and carrying the at least two energy generating units (5); and at least one escape route extending between a start and an exit. To provide a safe escape route, the load carrying structure forms at least a first section of the escape route from the start to an intermediate location, and the wind turbine comprises an escape opening in the nacelle, the escape opening leading from an interior space of a nacelle of the energy generating unit to a passage structure and the passage structure extending from the escape opening to the start of the escape route.

The present invention generally relates to a one-piece climbing sticks for use in climbing trees for hunting or other purposes. The climbing sticks of the invention are characterized by a double step, one-piece design wherein the center support structure and the double steps emanating therefrom are fabricated from a single sheet or piece of aluminum and/or aluminum alloy.
