This design main content includes: 1. The design of the type and span of the legs and the checkout of the stability; 2. The design ofr otation structure and its type; 3. The design ofh ydraulic system and the choice of the hydraulic units. The advantage of the design is simple structure and operation. It can help to design truck crane. Keywords : truck crane ; rotation fulcrum arrangement ; Leg ; Hydraulic system 购买后包含有 CAD 图纸和说明书,咨询 Q401339828 III 目录 1 绪论.............................................................................................................................................................. 1 概论..................................................................................................................................................... 1 随车起重机市场的发展水平和趋势................................................................................................ 1 随车起重机的数字化简介................................................................................................................ 2 2 随车起重机的技术参数...............................................................................................................
