A fall protection device for a user working on horizontal surfaces in construction sites, which can adopt two end positions: an operating protection position and a non-operating storage position. The device has a mast releasably couplable at the lower end to a fixed element of the construction with the possibility of pivoting on its own vertical shaft; an arm at a first end of an articulated joint articulated with the end of the upper portion of the mast, the second end thereof being free and the arm configured to receive in an area of the second end the coupling of fastening and attachment for the user; a strut with a first end articulately joined to the arm and with a second end to be fastened on a point of the upper portion of the mast under the end of the upper portion where the mast is articulated with the arm.

A device for attaching to exposed ribbed reinforcing bar at a construction site to form an anchor for a safety line comprises a tubular body defining a substantially cylindrical interior cavity diametrically sized and shaped in a manner substantially corresponding to a length of the reinforcing bar so that the interior cavity can be snugly received over the length of the reinforcing bar. The device includes an attachment location defined on the tubular body for connecting the safety line and features a plurality of grooves defined at the interior cavity and arranged to matably receive ribs of the reinforcing bar so as to secure the device in fixed location along the reinforcing bar. During construction of a structure, the device is used to support a worker against falling and thereafter may be left attached to the reinforcing bar and subsequently a remainder of the structure may be cast in concrete.

The anchoring device for shuttering walls includes a body containing an arm with a top tab, a fastening part for at least one connector, a moving closing part mounted in the body and pressed to the closed position at rest, and a locking part. The closing part is a sliding part with an indentation on one of its lateral surfaces which is matched with the slider lock in the open position of the device, and with pass-through pockets and a bottom tab, forming, together with the arm and the upper tab of the body, a tong closure assembly. The device has a set of springs, of which one pushing spring is located inside the body directly above the slider lock and is secured from above by a pressure screw. The three compression springs are located inside the body in the pass-through pockets of the slide.

A method for providing active fall prevention assistance to a user. The method includes one or more computer processors mapping a work area where a user performs a plan of tasks. The method further includes determining a safety configuration related to the user and the task. The method further includes instructing an autonomous device to attach a first tether between a first anchor point and a safety harness secured to the user. The method further includes analyzing real-time images of the work area and the user while the user performs the task. The method further includes determining that the user is at risk of falling. The method further includes responding to determining that the user is at risk of falling by instructing the autonomous device to attach a second tether between a second anchor point and the safety harness secured to the user.

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.

The present application relates to the technical field of aerial climbing and transportation operations, and provides a fall protection locking assembly, a fall protection device and a fall protection system. The fall protection locking assembly includes a fixed main body, configured to be installed to a rail through a first wheel body assembly containing a wheel shaft; a lockup member installed on the fixed main body and be switched between a lockup position and a free position; and a first trigger mechanism installed to the fixed main body, the first trigger mechanism includes a transmission member and a drive member, the transmission member is configured to be installed to the wheel shaft and rotate with the wheel shaft, and the transmission member is switched with changes in centrifugal force between a first position, in which the transmission member is disengaged from the drive member in the first position, and a second position, in which the transmission member transmits the rotation of the wheel shaft to the drive member so that the drive member rotates to drive the lockup member to move to the lockup position. When an operator accidentally falls, a wheel shaft will have a higher rotational speed, and then a transmission member will drive the drive member to move together under the action of centrifugal force, thereby driving the lockup member moves to the lockup position to ensure the safety of use.

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.

A mounting device may include a first arm, a first void defined in the first arm, a second arm, and a second void defined in the second arm. The first arm and the second arm may be engaged to one another via the first void and the second void. The mounting device may further include a top plate coupled to the first arm and the second arm.

A triangular-shaped mounting device may include a top plate. The top plate may include a triangular-shaped center portion, a first return formed on a first side of the triangular-shaped center portion, a second return formed on a second side of the triangular-shaped center portion, and a third return formed on a third side of the triangular-shaped center portion.

A mounting device may include a top plate including a cone-shaped center portion, a flange coupled to the cone-shaped center portion, a number of apertures defined in the flange, and a number of fasteners engaged with the apertures to couple the top plate to a surface of a structure. The flange seals a bottom side of the top plate to the surface of the structure. The flange includes a seal coupled to the bottom of the flange. The cone-shaped center portion has a convex paraboloid shape. The flange includes at least one surface that is parallel to a surface of the structure, and a transition between the cone-shaped center portion and the flange forms an angle. The top plate has a diameter sufficient to displace a load greater than 50 pounds over the surface of the structure.
