根据一九八○年底的不完全统计,我国贮木场龙门起重机与装卸桥已达130台左右,龙门起重机仅东北林区已有40台。由于对其防风装置的研究与重视不够,而导致出现过一些设备生产事故,影响了人身安全。为此,本文将国内几种防风装置予以评介,以供参考。一、起重机设置防风装置的必要性林业用的龙门起重机,装卸桥均在室外露天作业,而且迎风面积很大,为了保证起重机的安全,都采用防风装置。我国起重机设计规范(GB3811—83)规定,“室外作业的轨道式起重机应装设夹轨
According to the incomplete statistics at the end of 1980, the number of gantry cranes and loading bridges in the log yard in China has reached about 130 units, and the number of gantry cranes in the northeastern forest area has reached 40 units. Due to the insufficient research and attention on its windproof devices, it has led to some equipment production accidents that have affected personal safety. For this reason, this article will review several domestic wind protection devices for reference. 1. Necessity of installing windproof devices for cranes The gantry cranes for forestry and loading and unloading bridges are all operated outdoors in open air, and the windward area is large. In order to ensure the safety of cranes, windproof devices are used. China’s crane design code (GB3811-83) stipulates that “rail cranes for outdoor operations should be equipped with clip rails.
