一、环电葫芦的加载测试 在我国起重设备生产行业中,电动小车式环链电动葫芦(简称环电葫芦)是一种新型的轻小型起重产品,它具有体积小、重量轻、强度高、价格适宜等优点,特别适用于低建筑高度及空间较小的工作场所下的起重和搬运作业。 常见的对环电葫芦起重性能的检验方法是质量块加载法,它包括静态和动态加载的两个过程: (1)在环电葫芦不提升时,对被测产品加入1.5倍额定起重量的质量块,保持几分钟,以测定其静态性能。 (2)在环电葫芦提升时,对被测产品从额定起重量起,逐步加入质量块,直至观察到环电葫芦的链条打滑为止,记下此时的压力值和位移点,即为此被测环电葫芦的限载点,这个过程是动态加载。
First, the loading test ring hoist lifting equipment in China’s production industry, electric trolley electric chain hoist (ring hoist) is a new type of light small lifting products, it has a small size, light weight, strength High, affordable and other advantages, especially for low building height and space less work under the lifting and handling operations. Common hoisting capacity of the test method is the mass load method, which includes static and dynamic loading of the two processes: (1) in the ring hoist does not upgrade, the product to be measured by adding 1.5 times the rated capacity The mass is kept for a few minutes to determine its static behavior. (2) When the hoist hoist, the product under test from the rated weight, the gradual addition of mass until the ring hoist chain is observed slippery, note the pressure at this time and the displacement point, which is the Measured ring hoist limit point, the process is dynamically loaded.
