建筑机械化所从1975年起,对在10吨米至60吨米塔式起重机的回转与行走机构中所采用的液力偶合器进行过探讨。先后采用作用直径自150毫米至360毫米,有标准型、安全型多种型式。通过三百多台塔机上多年来实践证明采用液力偶合器对简化传动机构、隔离扭振、防护动力过载和节省能源等方面均有明显效果。 Construction mechanization Since 1975, the hydraulic couplings used in slewing and traveling mechanisms of 10-tonne meters to 60-tonne tower cranes have been discussed. Has adopted the role of diameter from 150 mm to 360 mm, a standard type, a variety of safety type. Through more than 300 tower cranes, it has been proven over many years that using a fluid coupling has obvious effects on simplifying the transmission mechanism, isolating the torsional vibration, protecting the power overload and saving energy.
