SAFETY CLIMB ATTENUATION APPARATUS
A safety climb attenuation apparatus provides a more robust and visually inspectable apparatus for climbing safety. In an upper bracket, a pivot arm is attached to a base that is disposed upon a structure. The upper bracket includes an attenuation member such as an elastic bushing, mounted on the pivot arm or the base, that resists pivoting of the pivot arm relative to the base when a safety cable attached to the pivot arm causes the pivot arm to pivot. In a lower bracket, a similar attenuation member is attached to a base disposed on the structure, with an anchor bolt connecting the cable to the attenuation member so that the attenuation member resists upward movement of the cable.
SLIDER DEVICE AND HANDRAIL APPARATUS
There is provided a slider device that includes: a slider main body that can move in the extending direction of a handrail while holding the handrail; and a plurality of pairs of rollers that are provided on the slider main body in a plurality of places apart from each other in the extending direction of the handrail, grasp side surfaces of the handrail, and can travel on the side surfaces of the handrail. One of the rollers facing each other across the handrail is a fixed roller fixed to the slider main body and the other of the rollers facing each other across the handrail is a movable roller supported in such a manner as to be able to get farther or closer with respect to the handrail, and each movable roller is biased toward the handrail by a biasing member.
Safety Cable System
A safety cable system for installation during building construction is provided and includes a first track mounted to a first structural element of a building, a first plurality of anchors slidably engageable with the first track, a second track mounted to a second structural element of a building, a second plurality of anchors slidably engageable with the second track, and a plurality of cables interconnecting the first plurality of anchors and the second plurality of anchors. The first plurality of anchors, the second plurality of anchors, and the plurality of cables are positionable vertically at a plurality of different heights above a floor of the building, or horizontally at a plurality of different positions above the floor. Also provided are stops for restricting movement of the first and second plurality of anchors, roller bearings that capture the plurality of anchors in the tracks and allow the anchors to slide with respect to the tracks, plates and associated mounting hardware for mounting the tracks, turnbuckles for tensioning the cables, and tie points for tying a netting between the tie points.

In a lower bracket, a similar attenuation member is attached to a base disposed on the structure, with an anchor bolt connecting the cable to the attenuation member so that the attenuation member resists upward movement of the cable.
ROOF-ANCHORING SYSTEMS AND METHODS
An improved roof anchoring system configured as a non-penetrating fall protection system with no nails or screws damaging the roof and including simultaneously used multiple anchoring devices each with a connector pivotally attached to a corresponding axle and each preventing another anchoring device from moving away from the roof edge and tensioned with respect to such other anchoring device via a common tether. A stopper can be optionally used to keep a given anchoring device in place during installation of the anchoring system.
Rooftop Rigging Support System
In at least one embodiment, a rooftop rigging support system mounts to a roof a building for suspending a load under an eave of the building. In some embodiments, the rooftop rigging support system comprises an arm that extends outward over the eave and then back inward underneath the eave. In some embodiments, the arm is a generally rigid, non-articulating structure. In some embodiments, the arm can be manually pivoted between a deployed position reaching under the eave and a withdrawn position extending above the roof.
REBAR BITER
A device may include an anchor point operationally connected to a rebar, an E-clamp coupled to the anchor point, and a forcing handle configured to tighten the E-clamp to the rebar.
Mobile fall protection unit for flatbed platforms
A mobile fall protection unit can be maneuvered by hand and brought to a flatbed with readily deployable, temporary fences for worker fall protection. The mobile fall protection unit can include a chassis, which carries a frame, which in turn carries a ladder as well as selectively deployable fall protection devices for worker fall protection. The frame carries a pair of retractable fall barriers separated from each other by about the width of the back of the flatbed.
SYSTEM, METHOD AND APPARATUS FOR FALL PROTECTION OF WORKERS AT A CONSTRUCTION SITE
A mount plate for a fall protection system includes a first wing, the first wing having a first body portion and a first flange perpendicular to the first body portion. The mount plate further includes a second wing, the second wing having a second body portion and a second flange perpendicular to the second body portion. The mount plate also includes a pivot pivotably connecting the first body portion to the second body portion and a through-hole configured to accommodate a slip sleeve of a lifeline tower.
Portable Truss Cable Roofing Safety Apparatus and Method
A portable truss cable roofing safety apparatus and method to assist users while working on the roof of a building structure. The portable apparatus provides a pair of similar opposing vertical trusses mounted adjacent opposite sides of the building structure. At least one brace is adaptable for securing each of the pair of vertical trusses to the building structure. A cable is connected to and extends between the pair of vertical trusses. An automatic belay device slidably is connected to the cable and has a safety line connected thereto, wherein the automatic belay device adjusts a length of the safety line to assist the user when the user is connected to the safety line.
