The invention discloses an electronic control multi-way valve integrating rotation control and a crane, the electronic control multi-way valve comprises a head link, a telescopic working link, a variable amplitude working link, an LS working link, an auxiliary lifting working link, a main lifting working link, a rotation working link, a tail link, a pilot oil way, a system oil return way, a control oil way, a load sensitive oil way and a main oil way, the plurality of working units are connected in parallel through the plurality of oil ways, and the electric control multi-way valve is further provided with a first main oil supply port, a second main oil supply port, a third oil supply port and a first oil return port. Therefore, the electric control multi-way valve integrates a control oil way and an oil return and recharging oil way, can provide action pilot control oil for each mechanism, saves an auxiliary pump and an oil recharging pump, simplifies a control pipeline, integrates an electric proportional control valve group, a buffer valve group and a free rotary valve group of a rotary mechanism, can greatly simplify pipeline arrangement of rotary control, saves space, and is convenient to assemble and disassemble. And the structure is more compact.

    本发明公开了一种集成回转控制的电控多路阀及起重机,电控多路阀包括:首联、伸缩工作联、变幅工作联、LS工作联、副起升工作联、主起升工作联、回转工作联、尾联、先导油路、系统回油路、控制油路、负载敏感油路、主油路,其中,上述多个工作联通过上述多个油路并联连接,电控多路阀还设置有第一主供油口、第二主供油口、第三供油口和第一回油口。由此,该电控多路阀集成控制油路、回油及补油油路,可提供各机构动作先导控制油,节省辅助泵、补油泵及简化控制管路,同时集成回转机构的电比例控制阀组、缓冲阀组、自由回转阀组于一体,可大大简化回转控制的管路布置,节省空间,使结构更加紧凑。
