20140020983 | ROPE GRAB - A rope grab for a vertical fall protection system is provided. The rope grab includes a housing with an elongated member passage. The elongated member passage is configured to receive an elongated member. A locking cam is pivotally coupled to the housing and selectively engages an elongated member received in the elongated member passage. A cam spring is coupled between the housing and the locking cam to provide a relatively slight biasing force on the locking cam in a direction towards an elongated member received in the elongated member passage. A locking arm, pivotally coupled to the housing, has a first end that is configured to be coupled to a safety harness of a user and a second end that selectively engages the locking cam to lock the locking cam on an elongated member in the elongated member passage during a fall event. | 01-23-2014 |
20130292219 | ENERGY ABSORBER - An energy absorber is provided that includes first and second strips of webbing, a plurality of tear yarns and first and second connection portions. The plurality of tear yarns couple a central section of the first strip of webbing to a central section of the second strip of webbing to form a mid portion of the first and second strips of webbing. The mid portion of the first and second strips of webbing has a centrally located unattached portion without tear yarns. The first connector portion couples a first webbing first end portion of the first strip of webbing and a second webbing second end portion of the second strip of webbing to a first connector. The second connector portion couples a first webbing second end portion of the first strip of webbing and a second webbing first end portion of the second strip of webbing to a second connector. | 11-07-2013 |
20130126269 | CONNECTING ADJUSTMENT ASSEMBLY - A connecting adjustment assembly for a fall protection assembly including a back plate assembly and a sliding engagement member is provided. The back plate assembly includes a body and a roller. The body has a first side and an opposed second side. The body further has a first edge and an opposed second edge that defines the length of the body. The body also has a third edge and an opposed fourth edge that defines a width of the body. The body still further has a groove in the second side that passes along the width of the body. The roller is rotationally coupled proximate the second edge of the body. The sliding engagement member includes a first portion with a first post and a second portion with a connection head. The first post is configured and arranged to be at least partially received within the groove of the body. | 05-23-2013 |

20130095968 | CABLE DRIVE AND TENSION ASSEMBLY - A tensioning assembly having a drive pulley, a tension pulley and a tension adjustment system is provided. The drive pulley has a first drive pulley channel and a second drive pulley channel. The tension pulley has a first tension pulley channel and a second tension pulley channel. The second tension pulley channel is aligned with the first drive pulley channel. The first drive pulley channel and the second drive pulley channel of the drive pulley and the first tension pulley channel and a second tension pulley channel of the tension pulley are configured and arranged to engage and route an endless looped member. The tension adjustment system is coupled to adjust the distance between the drive pulley and the tension pulley to adjust the tension in the endless looped member in relation to the drive pulley. | 04-18-2013 |
20130091690 | CABLE CONNECTOR ASSEMBLY - A cable connector assembly comprises a first stop, a second stop, and a connector. The first stop is configured and arranged to receive a first end of a cable, and the second stop is configured and arranged to receive a second end of the cable. The connector is configured and arranged to pivotally interconnect the first stop and the second stop. | 04-18-2013 |
20120298446 | RETRACTABLE HORIZONTAL LIFELINE ASSEMBLY - A retractable horizontal lifeline assembly includes a lifeline windable about and paid out from a rotatable drum and a housing. The housing includes a first connector and is configured and arranged to house the drum and the lifeline wound about a base of the drum. The first connector is operatively connected to a first anchorage structure, the lifeline is pulled outward from proximate the housing thereby paying out at least a portion of the lifeline from the drum, a second connector operatively connected to the lifeline is operatively connected to a second anchorage structure, and the lifeline is tensioned using a crank that rotates the drum to increase the tension in the lifeline and provides indication when the tension in the lifeline reaches a predetermined level. | 11-29-2012 |
20120298445 | RETRACTABLE HORIZONTAL LIFELINE ASSEMBLY - A retractable horizontal lifeline assembly includes a lifeline, a drum, and a crank. The lifeline has an intermediate portion interconnecting a first end and a second end. The drum has a base and is rotatable. The first end of the lifeline is operatively connected to the drum and the intermediate portion of the lifeline is windable about and paid out from the base. The drum is operatively connected to a first anchorage structure. The second end is operatively connected to a second anchorage structure. The crank is configured and arranged to be releasably connectable to the drum and is rotatable to rotate the drum and tension the lifeline. The crank includes a tension indicator to provide indication when the tension in the lifeline has reached a predetermined level. The crank is capable of tensioning the lifeline to a level greater than the predetermined level. | 11-29-2012 |
20110147125 | FALL PROTECTION SAFETY DEVICE WITH A BRAKING MECHANISM - A fall protection safety device including a braking mechanism comprises a first component, a second component configured and arranged to move relative to the first component, and at least one magnet operatively connected to one of the components and another of the components being at least partially made of a non-ferromagnetic and electrically conductive material. The at least one magnet and the non-ferromagnetic and electrically conductive material creating an electromagnetic field force when the second component moves at a rate greater than a predetermined rate relative to the first component. | 06-23-2011 |
