在救援抢险高空作业施工时，混合臂高空作业车具备折叠臂与伸缩臂高空作业车二者的优点，高空作业部分采用两节折叠臂+三节伸缩臂结构，其中两节折叠臂由一根油缸驱动，两节臂间装有连杆，可实现同步变幅以便节约时间，增加跨越能力，提高工作效率；三节伸缩臂分别由变幅油缸驱动变幅、由伸缩油缸驱动两节伸缩臂同步伸缩。下折臂与转台铰接，在回转机构驱动下，转台带动臂架、工作斗进行±360º连续回转。

In the emergency rescue overhead construction, the mixed-arm overhead working truck combines the advantages of folded arm and telescopic arm overhead working trucks, the portion for overhead operation adopts the structure of two folded arms plus three telescopic arms, the two folded arms are driven by one hydro-cylinder, and mounted with the connecting rod to achieve synchronous amplitude so as to save time, increase spanning capability and improve working efficiency; three telescopic arms are driven by hydro-cylinder with variable amplitudes respectively, and two telescopic arms are driven by telescopic hydro-cylinder to achieve synchronous telescoping. Lower folded arm is hinged with turntable, which drives the boom and working hopper to make continuous rotary of ±360º under the driving of rotating mechanism.
