Abstract: An anchorage device that includes a receiver having a body having an aperture along an axis, the aperture having a first section of a first size and a second section of a second size, the second size being smaller than the first size, the first section having a first retaining recess, and the second section having a second retaining recess. The receiver cooperates with a male connector adapted for insertion into the aperture of the receiver, the male connector includes a set of parallel retractable retaining mechanisms located along the male connector. The system provides for engagement of at least two of the retractable mechanisms against the receiver.

Abstract: A method for creating a horizontal lifeline between a pair of end anchorages. The method includes providing a section of line having a modulus of elasticity, providing an energy absorbing shock absorber having a deployment load, connecting the section of line and the shock absorber to one another, between the end anchorages, and tuning the section of line by tensioning the section of line to a load that is approximately equal to the deployment load.

Abstract: A receiver assembly for retaining a stanchion between a pair of looped supports. The receiver includes a support frame and a receiver support, the receiver support, the receiver support being adapted for engaging and retaining the stanchion. The receiver assembly also includes a locking bar that extendins from the support frame. The locking bar is adapted for engaging the pair of looped supports while extending between the pair of looped supports, so that the stanchion is retained in a generally upright position by the cooperation of the base and the locking bar with the looped supports.

Abstract: An energy absorption device is disclosed for use both as in-line and horizontal life line shock or energy absorbers for fall arrest systems. The device includes a sleeve through which a bolt head is drawn. The bolt head compresses from the interior surface of the sleeve and thus absorbs energy as the device is stretched during a fall.

Abstract: A safety hook that includes a hook portion having a hook body with a shank portion, a nose portion and a mouth between the shank and the nose portion, a gate having a closure and at least one web portion along a plane is mounted on the hook body. The web portion of the gate includes a protrusion that extends away from the plane of the web portion and towards the mouth of the hook. A locking element with at least one wall portion that has a slot adapted for receiving the protrusion of the gate is mounted against the shank of the hook body. The wall portion will preferably be mounted between the web and the shank of the hook so that the locking element is movable from a first position, where the wall portion impedes motion of the protrusion on the web portion of the gate, and a second position where the slot receives the protrusion on the web portion, allowing opening of the gate, so that the gate can move to provide access to the mouth of the hook.

Abstract: Clamping apparatus for providing a fixed support on a fixed beam or other similar structures wherein outer and inner elongated members are mounted for relative sliding telescoping movement therebetween and are moved by a rotatable threaded bolt and each of the outer and inner elongated members have an inclined surface so that when the inclined surface of the jaws contact the opposite side edges of the fixed beam the facing surfaces of the fixed beam and the outer and inner elongated members are moved into intimate contact.

Abstract: A shock absorbing device for a generally horizonal lifeline wherein one end of the lifeline is mounted at fixed location, the other end of the lifeline is connected to one end of the shock absorbing device, one end of a turnbuckle is connected to the other end of the shock absorbing device and the other end of the turnbuckle is mounted at a fixed location. The shock absorbing device has a frangible bolt that breaks when a predetermined amount of force is applied thereto, which force is then absorbed by shock absorbing device. Also, shock absorbing devices are used to connect electric power cables to spaced apart supports.

Abstract: Apparatus and method for securing an anchor strap in a relatively fixed position at a location which is spaced a substantial distance from a fixed surface wherein the anchor strap has a relatively flexible intermediate portion, a relatively rigid one end portion having an anchor ring secured thereto and a closed loop at the other end portion and wherein an operating tool mounted on the end of an extensible handle is used to pass the relatively rigid one end portion over a fixed support and then pull the relatively rigid one end portion through the closed loop to secure the anchor strap on the fixed support and wherein another operating tool mounted on the end of the extensible handle is used to connect or disconnect a snap hook, having a lifeline attached thereto, to or from the anchor ring. In another embodiment, a portion of the relatively flexible intermediate portion extending from the relatively rigid one end portion is provided with stitching to add rigidity thereto.

Abstract: A system for indicating the use of a fall arresting device to arrest a fall wherein a collapsible member is mounted on one of the load supporting members so that the collapsible member will collapse when a predetermined load has been applied thereto but will remain substantially in place to indicate that the predetermined load had been applied thereto.

Abstract: Apparatus for mounting load supporting equipment, such as a D-ring, on a fixed vertical or horizontal support wherein a movement preventing device is used to hold an elongated strap of material in position on the fixed support by preventing relative movement between superposed end portions of the elongated strap and wherein, in one embodiment, a support member for supporting the load supporting equipment is secured to the movement preventing device and in another embodiment a support bracket for supporting the load supporting equipment is held in a location against a portion of the fixed vertical or horizontal support.

Abstract: A fall arresting device is provided having fall arresting apparatus which permits application of a force to rotate a shaft in a clockwise direction and permits controlled rotation of the shaft in a counter-clockwise direction but prevents uncontrolled rotation of the shaft in the counter-clockwise direction. Safety apparatus is provided for preventing damage to portions of the arresting apparatus.

Abstract: Apparatus for limiting the amount of force applied to a cable of a hoist by applying a force on clutch plates which are operatively joined to rotatable plates so that there is relative rotation between the clutch plates and the rotatable place when a force, equivalent to that placed on the clutch plates, is placed on the load supporting end of the cable. A fall arresting device is also provided having arresting apparatus for applying a force to rotate a shaft in a clockwise direction and for permitting controlled rotation of the shaft in a counter-clockwise direction but arresting uncontrolled rotation of the shaft in a counter-clockwise direction.

Abstract: Apparatus for moving personnel or materials through an opening in a sidewall of a vessel and down into the vessel wherein a lower support and an upper support are mounted on the portion of the sidewall defining the opening and have a tripod supported thereon and located within the vessel. A hoist and a fall arresting device are mounted on the upper support and the cables thereof are passed over pulleys mounted on the tripod so that personnel or materials may be attached to the snaphook on the end of the cable and moved through the opening and lowered into the vessel.

Abstract: Apparatus for limiting the amount of force applied to a cable of a hoist by applying a force on clutch plates which are operatively joined to rotatable plates so that there is relative rotation between the clutch plates and the rotatable place when a force, equivalent to that placed on the clutch plates, is placed on the load supporting end of the cable. Also, two fall arresting devices are provided.
