Retractable type fall arresters are very effective personal equipment protecting against falls from a height. These devices are used under different atmospheric conditions and in the presence of various types of industrial pollution. For this reason appropriate locking after conditioning simulating extreme conditions of a worksite is one of the essential characteristics of retractable type fall arresters. This article presents the requirements for locking of the devices. A previously used locking test method and its disadvantages are discussed. The article suggests an improved test method and test equipment. Measurement of the test mass acceleration is the most important improvement introduced into the test method. The article shows laboratory tests used to verify the method, which turned out to be a valuable source of information concerning the performance of retractable type fall arresters.
可伸缩式防坠落装置是一种非常有效的个人防坠落设备，可防止从高处坠落。这些装置在不同的大气条件下和存在各种类型的工业污染的情况下使用。因此，在模拟工作场所极端条件下进行适当的锁定是可伸缩式防坠落装置的基本特性之一。本文介绍了对装置进行锁定的要求。讨论了以前使用的锁定测试方法及其缺点。本文提出了改进的测试方法和测试设备。测试质量加速度的测量是引入测试方法的最重要改进。本文展示了用于验证该方法的实验室测试，这些测试结果为可伸缩式防坠落装置的性能提供了有价值的信息来源。
