A weight-activated anchoring and alerting apparatus which serves as both (a) an anchoring device or anchoring extension for a fall arrest or other fall protection system and (b) an automatic alarm system which notifies rescue personnel or others when the worker, hunter, or other person wearing the fall protection system has fallen and is in need of rescue.

An expansion bolt and pivot and swivel mechanism therefor. The expansion bolt may have a base and a plurality of radially spreadable elongate elastic members cantileveredly projecting from the base at respective points of joinder to the base and terminating in respective spoons at respective points of joinder of the spoons, wherein the elongate elastic members have respective radially defined thicknesses at the points of joinder to the base that are substantially less than the corresponding thicknesses of the base, and respective radially defined thicknesses at the points of joinder of the spoons that are substantially less than the corresponding thicknesses of the spoons. The pivot and swivel mechanism may have a ring element that includes two spaced apart leg members having foot portions that turn to extend toward each other, the foot portions having respective, spaced-apart relatively enlarged ends; a swivel housing element having an open end for receiving and at least partially containing the ends of the foot portions so that the ring element can be substantially freely rotated about a pivot axis; and a capping element adapted for interlocking with the open end of the swivel housing element, the capping element having a bottom surface portion of radial symmetry about a swivel axis that is distinct from the pivot axis.

The present disclosure provides two exemplary, non-limiting embodiments of a roof access system comprising a roof anchor assembly for providing one or more users thereof with supplemental stabilization while traversing a sloped rooftop. The roof anchor assembly comprises two or more eave anchors, a ridge plate, and two or more safety lines. The roof anchor assembly is designed to be used on structures comprising roofs which further comprise a ridge and two or more eaves. The two or more eave anchors are installed at eaves on opposing sides of the structure and the ridge plate is placed at the ridge in between the two eave anchors. Each eave anchor is designed to be engaged when the user is traversing the sloped rooftop on the opposing side of the ridge relative to the side that the eave anchor is installed.

An improved roof safety system allows temporary installation without damaging the roof or building by using non-penetrating C-shaped anchors to hook onto eaves on opposing sides of the roof with the anchors connected by a single, continuous anchor line under tension. Installation of primary components do not require a user to access the roof, as they may be installed from the ground or a ladder position. Slidable anchors connectable to an anchor line and lifeline allow free movement along the line in a first direction and block movement in a second opposite direction, allowing a user to anchor to the line at a selected position and then securely move about the roof's surface in an area generally disposed in the second direction while being protected from a fall. An optional wedge-stopper can aid in single-user installation.

A post system for use in fall protection includes a connector to connect to a structure and a support in operative connection with a lifeline to maintain the lifeline at a first height above the structure. When a first threshold force is experienced on the lifeline, the support is operable to lower the lifeline to a second height which is lower than the first height. The ratio of a change in effective length of the lifeline resulting from the lowering of the lifeline to a change in height resulting from lowering of the lifeline (or the ΔL/ΔH ratio) is less than 1. The ratio of the change in effective length of the lifeline resulting from the lowering of the lifeline to the change in height resulting from lowering of the lifeline may also be less than 0.5 or less than 0.4.

A parapet descent apparatus can include a mounting panel configured to be secured to the parapet of an elevated structure; and a parapet ladder secured to the mounting panel and including: a first ladder rail; a second ladder rail; and a plurality of rungs, each of the plurality of rungs extending from the first ladder rail to the second ladder rail, the parapet ladder defining a first end configured to be secured to the parapet of the elevated structure and a second end distal from the first end and configured to contact a surface of the elevated structure, a top surface of the parapet being offset above the surface of the elevated structure by a wall height of the parapet.

Systems and methods for monitoring and reporting the condition of a permanent fall-protection safety system. The systems and methods use a sensor to obtain data corresponding to a physical state of at least one component of the safety system, the at least one component and the sensor being at a remote location and/or at an elevated height, relative to a base unit. The systems and methods further include wirelessly transmitting the data to the base unit, processing the data to reach an indication of a change in a physical state of the at least one component of the safety system, and reporting the condition of the safety system based on the indication of the physical state of the at least one component of the safety system.

A fall protection system can include towers configured to be coupled together with horizontal lifelines. Each tower can have a base removably coupled to a bottom of the frame. A lower slip sleeve can be slidably coupled to the base. The lower slip sleeve can have an elongate opening extending therethrough. An internal piece can be slidably received in the elongate opening and coupled to the lower slip sleeve. In addition, an upper slip sleeve can be coupled to an exterior of the internal piece such that the upper slip sleeve is not movable relative to the internal piece. Further, a mount plate can be slidably coupled to an exterior of the upper slip sleeve and mounted to a top of the frame. Finally, a stanchion can be slidably received in the upper elongate opening and coupled to the upper slip sleeve.

A roof attachment system and methods of using same during the installation, maintenance, or repair of a roof on a commercial or residential building structure. The roof attachment system and the related methods of using and implementing the system include, among other things, an anchor or internal support assembly, and a hook or securement assembly. The roof attachment system enables the installer to utilize at least one internal support assembly, or at least one internal support assembly and the securement assembly to install the roof, depending upon the installation stage of the roof. Upon completion of the installation process, the roof includes multiple concealed internal support assemblies that provide multiple anchor points that are spaced an appreciable distance apart along the ridgeline of the roof. When the roof requires maintenance or repair, the securement assembly can be removably coupled to a specific internal support assembly to facilitate the maintenance or repair by a technician while also reducing the chances that the technician experiences a fall from the roof.

A method for using a mobile anchor cart assembly can include repositioning the mobile anchor cart assembly from an anchored position to a mobile position on a ground surface, mobile anchor cart assembly including a cart, the cart including a frame resting upon the ground surface in the anchored position, the frame clearing the ground surface in the mobile position; and an axle assembly mounted to the frame, the axle assembly clearing the ground surface in the anchored position, the axle assembly contacting the ground surface in the mobile position; and a load defining a load center of gravity, the load center of gravity being vertically aligned over at least a portion of the axle assembly in the anchored position; and rolling the mobile anchor cart assembly along the ground surface with the axle assembly.
