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： A structural post for fall arrest and rope access has a baseplate having baseplate fixing holes. A vertical mast is attached to an upper surface of the baseplate, and a main attachment plate comprising main attachment plate fixing holes is affixed to an upper end of the mast. The structural post may be mounted to concrete floor garden landscapes, steel structures and the like on high-rise buildings, for fall arrest and rope access, and which facilitates versatility and adaptability for various locations and applications, for construction, beside cleaning and other building and maintenance activities.

摘要： A vertical fall arrest safety device travels along a rail of a vertical track and is configured for quick attachment and detachment anywhere along the rail. The device has a mounting body having side rail engagements configured for slidably engaging behind the edges of a rail of the vertical track in use. The engagements are spaced and staggered so as to receive the rail therebetween when the mounting body is at an angle, and then slidably attach to the rail when the mounting body is twisted into alignment with the rail. The device also has a lever pivotally coupled to the mounting body at a fulcrum. As such, when a downward force is applied to a connection point of a distal end of the lever, an opposite distal end of the lever frictionally engages the rail.
