摘要： 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.

摘要： A system is provided for safe access to a roof through an opening in a roof of a structure having a fixed ladder leading upward to the opening. The system includes a mechanism to drive a set of pushrods to raise a hatch covering the opening. The system may include a section of ladder secured to the underside of the hatch. The system may have an extendable ladder driven by the drive mechanism to slide along the fixed ladder and extend through the opening in the roof when the hatch is raised. The system may include a safety pole driven by the drive mechanism to extend through the opening in the roof when the hatch is raised. The system allows someone who needs to access the roof for inspection or maintenance to safely open the hatch, climb up through the opening in the roof, and safely step onto the roof.

摘要： A modular ladder system has a rung section having two elongate lateral stile extrusions and elongate rung extrusions spanning therebetween. Each stile extrusion may define an attachment side having an attachment face which has two attachment channels which are adjacent, parallel and longitudinally arranged along the attachment face. Each attachment channel may have inward facing rails which define an elongate insertion space therebetween and a relatively wider connector head accommodation void thereunderneath. Furthermore, each rail may define a connector head engaging under edge. Each stile extrusion may further define a connection side adjacent to the attachment side which may define a splice joint extrusion accommodating void therein. In this way, the present modular ladder system may be quickly and easily constructed and various accessories quickly and easily attached thereto.

摘要： 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.

摘要： A vertical ladder has two side stiles and at least one front vertical rail. Two sets of half treads are supported by each stile and horizontal rung members connected between at least one rail and a respective half tread or stile. Each horizontal rung member only has a front straight bar portion that terminates orthogonally at the at least one rail (i.e. at a T-junction), thereby allowing a vertical grab rail portion for gripping (including for counterbalance) and an orthogonal side straight bar portion. The rung members and half treads are alternately vertically staggered. As such, a user may ascend the ladder by stepping sideways onto the inward facing half treads and shift the user's weight from side to side, thereby being able to climb the ladder even without holding on and, when holding on, the vertical grab rail portions may be used for counterbalance.

摘要： A retractable deer stand ladder system for providing a ladder that is efficiently concealed from wildlife. The retractable deer stand ladder system generally includes a support member having an elongated structure, an upper end and a lower end, a plurality of first steps pivotally attached to a first side of the support member, and a plurality of second steps pivotally attached to a second side of the support member. The first steps and the second steps each have an extended state where the steps extend outwardly from the support member for a user to climb upon. The first steps and the second steps also have a retracted state where the steps extend substantially parallel with respect to the support member for concealment.

摘要： The present disclosure is directed to a ladder attachment system for securing a ladder within a tower of a wind turbine. The ladder has parallel legs and a plurality of rungs arranged perpendicularly between the parallel legs. The ladder attachment system includes at least one external stiffener configured at a top end of each of the parallel legs. Each of the external stiffeners includes a longitudinal body having an open cross-section configured to receive one of the parallel legs along a length thereof. Further, the ladder attachment system also includes a load-bearing bracket assembly configured with each of the external stiffeners. In addition, the ladder attachment system includes at least one support arm arranged in a horizontal plane and configured with each of the parallel legs, with the support arms being spaced apart from the load-bearing bracket assembly along a height of the ladder.

摘要： There is provided a climbing locking system for climbing ladders in particular of a wind power installation. The climbing locking system has at least one climbing ladder segment having a longitudinal direction and at least one open end for accommodating a fall arrester which can move back and forth as a climbing protection system along the longitudinal direction. The climbing locking system also has at least one climbing locking unit at the at least one open end of the climbing ladder segment. The climbing locking unit is fastened pivotably to the climbing ladder segment and has a locking position for locking a movement of a fall arrester along a direction of the climbing ladder segment and a passing position for allowing a movement of the fall arrester along the longitudinal direction of the climbing ladder segment in both directions.
