Abstract
Изобретение относитс к подъемно- транспортным устройствам, в частности к механизмам фиксации в вертикальном положении подъемной люльки стреловых подъемников. Цель изобретени - предотвращение раскачивани люльки и повышение надежности фиксации ее относительно верхнего конца стрелы. Поставленна цель достигаетс за счет того, что действие внешних нагрузок на люльку 6 передаетс на цепной контур, образованный рабочей 4 и направл ющей 3 звездочками, а концы цепи 2 соединены с двусторонним штоком гидроцилиндра 1, закрепленного на секции 7 стрелы, при этом полости через гидроцилиндры 1 сообщены трубопроводом 8 через вентиль 9. 3 ил.The invention relates to lifting and transporting devices, in particular to locking mechanisms in the vertical position of the lifting platform of the boom lifts. The purpose of the invention is to prevent the cradle swinging and to increase the reliability of fixing it relative to the upper end of the boom. The goal is achieved due to the fact that the external loads on the cradle 6 are transmitted to a chain loop formed by working 4 and a guide with 3 asterisks, and the ends of chain 2 are connected to a double-sided rod of a hydraulic cylinder 1 fixed to boom section 7, and the cavities through the hydraulic cylinders 1 communicated by pipeline 8 through the valve 9. 3 Il.
