    摘要： The present application relates to the technical field of linkage mechanisms, and provides a linkage operation assembly, a fall protection device and a fall protection system. The linkage operation assembly includes a fixed main body configured to be installed on an outer support surface of a rail and move along the rail; a second wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a second wheel set and a drive rotary shaft; a third wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a third wheel set and a driven rotary shaft; and a linkage member disposed between the drive rotary shaft and the driven rotary shaft. When the drive rotary shaft of the linkage operating assembly rotates, the second wheel set is driven to rotate, and the driven rotary shaft and the third wheel set are driven to rotate through the linkage member. Therefore, during the installation process of the linkage operation assembly, only the drive rotary shaft needs to be rotated to switch the state of the linkage operation assembly, so as to facilitate the installation of the linkage operation assembly. Similarly, when the linkage operation assembly is disassembled, only the drive rotary shaft needs to be rotated.

    摘要： I-beam-attachable lifeline system, including methods and apparatus, for worker safety. In some embodiments, the system may comprise a frame structure including upright columns and horizontal I-beams. The system also may comprise a pair of fittings connected to a horizontally-spaced pair of the I-beams. Each fitting may have a first hook component and a second hook component received on respective opposite edge regions of a flange of an I-beam of the pair of I-beams and attached to one another with a fastener such that the fitting spans the flange transversely and is supported by the I-beam. The system further may comprise a cable having opposite ends connected to the pair of fittings.

    摘要： A fall arrest device for securing a climber to a cable in a manner that prevents the climber from falling. The device can run along an elongate securing cable as the climber ascends and descends during use. The device has a base body having a guide element and a receiving body having longitudinal axis designed to receive the cable therebetween, a housing fastened movably on the base body, and a securing element having a first securing bolt. The securing element is fastened rotatably on the base body and the housing in order to clamp the cable against the receiving body to arrest the climber during a fall.

    摘要： A bifurcation method and system for a passive continuous belay system that allows for a user to select multiple pathways using intermediate tracks. A main track and the intermediate tracks provide a linear passive continuous belay using an anchor mechanism that is configured to grasp the outside of the structural member track, using rolling elements and/or low-friction sliding. The user may select multiple pathways using intermediate lateral tracks to provide Cartesian movement at designated (e.g., perpendicular) transition or junction points. Desired tracks may be selected by a user via sliding along a support plate or track in a junction box and/or by rotating a portion of the junction box. Amusement attraction activities that include non-harnessed play may be intertwined or located adjacent to activities utilizing harnessed play.

    摘要： The cable grab safety device releasably attaches a workman's safety lanyard to a steel cable. A primary frame constructed of an elongated U-shaped bracket having a pair of spaced apart parallel side plates fits around the cable. A secondary frame also comprised of a pair of side plates fits within the U-shaped bracket after the cable is inserted. The secondary frame carries a brake in the form of a pulley mounted in an elongated slot movable toward or away from the cable. A lever attached to a worker's lanyard moves the pulley only in the inward direction to engage the cable in the event of a fall. A bent pin connected between the primary and secondary frames allows for limited pivotal and axial movement between them allowing the cable to be inserted into the U-shaped bracket. A separate locking pin secures the frame members together.
