    • A retractable lifeline safety device usable as heights above the ground. The safety device is attached to the structure on which the worker is performing the task, and a lifeline such as a cable is withdrawn from the housing thereof, the end of which is attached to a belt or harness worn by the worker. The cable may be easily drawn out of the housing in response to the worker moving about normally in the appropriate work space, and the cable is automatically drawn back into the housing of the safety device as the worker draws closer thereto. However, should the worker fall, a brake mechanism within the safety device is automatically engaged by a sprocket and pawl system, stopping the worker's descent.
    • 可用于地面高度的可伸缩救生索安全装置。 安全装置安装在工作人员正在执行任务的结构上,并且诸如电缆的救生索从其壳体中撤出,其末端附接到由工人佩戴的皮带或线束。 响应于工作人员在适当的工作空间中正常移动,电缆可以容易地从外壳中拉出,并且随着工人更靠近电缆,电缆被自动地拉回到安全装置的壳体中。 然而,如果工作人员掉落,则安全装置内的制动机构由链轮和棘爪系统自动接合,从而阻止工人的下降。
