Retractable type fall arresters are designed to protect against falls from a height of people who need freedom of vertical movement. The practice of fall protection shows that the devices are also used to protect people who work on flat roofs. This application creates quite different operating conditions for the devices. In some situations those conditions can be dangerous for users. The article presents a theoretical analysis of phenomena occurring during a fall arrest with retractable type fall arresters arranged horizontally. The analysis was verified with laboratory tests. The article presents a proposal for the construction of a test stand and a test method for estimating retractable type fall arresters intended for horizontal use.
伸缩式防坠落装置旨在保护需要垂直移动自由的人员防止高处坠落。防坠落实践表明，这些装置也用于保护在平屋顶上工作的人员。这种应用为这些装置创造了截然不同的运行条件。在某些情况下，这些条件可能对使用者构成危险。本文对水平布置的伸缩式防坠落装置在制动坠落过程中出现的现象进行了理论分析。该分析通过实验室测试进行了验证。本文提出了一种试验台的构造方案以及一种用于评估水平使用的伸缩式防坠落装置的测试方法。
