Retractable type fall arresters are part of the equipment used for protecting people against falls from a height. They are an intermediate part between full body harness worn by a man and the structural anchor at the worksite. The most important task of retractable type fall arresters is to arrest people's falls and to reduce their harmful consequences. Information received from users as well as laboratories testing protective equipment indicates that the performance of such equipment is incorrect under specific conditions. The paper is concerned with an analysis of the conditions in which retractable type fall arresters demonstrate intermittent performance and with an explanation of that phenomenon. The results of tests investigating anchor devices and the performance of retractable type fall arresters are presented. External and internal factors contributing to intermittent performance have been determined and guidelines for safer use of these devices have been developed.
伸缩式防坠落器是用于保护人员防止高处坠落的设备的一部分。它们是人员所佩戴的全身安全带与工作现场结构锚点之间的中间部件。伸缩式防坠落器最重要的任务是阻止人员坠落并减少其有害后果。从用户以及测试防护设备的实验室获得的信息表明，此类设备在特定条件下性能不正确。本文关注对伸缩式防坠落器表现出间歇性性能的条件进行分析，并解释该现象。文中给出了对锚固装置和伸缩式防坠落器性能的测试结果。已确定导致间歇性性能的外部和内部因素，并制定了这些设备更安全使用的指南。
