Measuring the swing angle of a crane load is a relatively well-known but unsatisfactorily solved problem in technical practice. This measurement is necessary for the automatic stabilization of load swing without human intervention. This article describes a technically simple and new approach to solving this problem. The focus of this work is to determine the accuracy of the measuring device. The focus of this work remains on the design, the principle of operation of the equipment, and the determination of accuracy. The basic idea is to apply the strain gauge on an elastic, easily deformable component that is part of the device. One part of the elastic component is fixedly connected to the frame; the other part is connected to the crane rope by means of pulleys close to the rope. In this way, the bending of the elastic component in proportion to the swing angle of the payload is ensured.
测量起重机负载的摆角在技术实践中是一个相对知名但未得到满意解决的问题。为了实现无需人工干预的负载摆动自动稳定，这种测量是必要的。本文介绍了一种技术上简单而新颖的解决此问题的方法。这项工作的重点是确定测量设备的精度。这项工作的重点仍然是设备的设计、工作原理以及精度的确定。基本思路是在弹性、易变形的组件上应用应变计，该组件是设备的一部分。弹性组件的一部分与框架固定连接，另一部分通过靠近绳索的滑轮与起重机绳索连接。这样，就可以确保弹性组件的弯曲与负载的摆动角度成比例。
