| Description | Les aspects de la présente invention concernent le domaine des systèmes de prévention de chute, et plus particulièrement des systèmes d'arrêt de chute pour des bacs de stockage et plus particulièrement des trémies ou des silos à grains. Selon un aspect, un système de prévention de chute pour une échelle peut avoir une plaque d'ancrage accouplée à un toit. Selon un autre aspect, le système de prévention de chute pour l'échelle peut avoir une barre d'ancrage accouplée à au moins une partie de l'échelle. Un câble est accouplé au niveau d'une extrémité à la plaque ou à la barre d'ancrage et au niveau de l'autre extrémité à au moins un barreau de l'échelle au moyen d'un élément de fixation. Un dispositif de préhension de câble est accouplé de manière coulissante au câble entre la plaque ou la barre d'ancrage et l'élément de fixation. |
| Abstract | The aspects herein relate to the field of fall prevention systems, and more specifically to fall arrest systems for storage bins and more particularly to grain bins or silos. In one aspect, a fall prevention system for a ladder may have an anchor plate coupled to a roof. In another aspect, the fall prevention system for the ladder may have an anchor bar coupled to at least a portion of the ladder. A rope is coupled at one end to the anchor plate or bar and at the other end to at least one rung of the ladder using a fastener. A rope grab is slidably coupled to the rope between the anchor plate or bar and the fastener. |

| Claim | What is claimed is: A fall prevention system for a ladder comprising: an anchor plate coupled to a roof; a rope coupled at one end to the anchor plate; a fastener for coupling another end of the rope to at least one rung of the ladder; and a rope grab slidably coupled to the rope between the anchor plate and the fastener. The fall prevention system of claim 1, further comprising a lanyard coupled to the rope grab. The fall prevention system of claim 2, further comprising a harness coupled to the lanyard. The fall prevention system of claim 1, wherein the anchor plate is sized to fit across at least two ribs extending downward from a peak of the roof. The fall prevention system of claim 4, wherein the anchor plate is planar. The fall prevention system of claim 4, wherein the anchor plate is trapezoidal in shape. The fall prevention system of claim 4, wherein the anchor plate further comprises a plurality of orifices through the anchor plate and along at least two edges of the anchor plate. The fall prevention system of claim 7, wherein the orifices comprise slotted holes that when the anchor plate is installed on the roof, the slotted holes are transverse to the ribs. The fall prevention system of claim 7, wherein each of the orifices receive a bolt passing through the anchor plate and a hole through at least one of the ribs. The fall prevention system according to claim 9, wherein the bolt additionally passes through at least one washer. The fall prevention system according to claim 10, wherein the at least one washer seals the hole through the at least one of the ribs. The fall prevention system according to claim 1, wherein the anchor plate is integrally formed with the roof. The fall prevention system according to claim 1, wherein the fastener comprises at least two rope clips. The fall prevention system according to claim 1, wherein the rope couples to the anchor plate using a connection loop and a shackle. The fall prevention system according to claim 1, wherein the rope grab is removable from the rope. A fall prevention system for a ladder comprising: an anchor bar coupled to at least a portion of the ladder; a rope coupled to the anchor bar; a fastener for coupling another end of the rope to at least one rung of the ladder; and a rope grab slidably coupled to the rope between the anchor bar and the fastener. The fall prevention system of claim 17, further comprising a lanyard coupled to the rope grab; and a harness coupled to the lanyard. The fall prevention system according to claim 17, wherein the anchor bar is integrally formed with the ladder. The fall prevention system according to claim 17, wherein the rope couples to the anchor bar using a connection loop and a shackle. A silo comprising: at least one wall extending upward from a base to a roof; a ladder extends from a bottom of the at least one wall to the roof; and a fall prevention system according to any one of claims 1 to 19. |
