The invention belongs to the technical field of universal chassis cranes, and particularly relates to an auxiliary frame and engineering machinery. The auxiliary frame comprises an auxiliary frame main body and an auxiliary frame bottom beam; the auxiliary frame bottom beam is connected with a chassis crossbeam of the engineering machinery positioned below; the shape of the upper portion of the auxiliary frame bottom beam is matched with the shape of the lower end face of the auxiliary frame body, the auxiliary frame bottom beam is connected with the auxiliary frame body located on the upper portion, and the width of the auxiliary frame bottom beam is smaller than that of the auxiliary frame body. The universal chassis crane solves the problems that the overall space arrangement of the universal chassis crane is difficult, the section width of the auxiliary frame main body is limited, and the planeness of a bottom plate of the auxiliary frame main body is limited due to direct connection of the auxiliary frame main body and the universal chassis.
本发明属于通用底盘起重机技术领域,具体涉及一种副车架及工程机械。副车架包括副车架主体,还包括副车架底梁;副车架底梁与位于下方的工程机械的底盘大梁连接;副车架底梁上部形状与副车架主体的下端面形状相匹配,副车架底梁与位于上方的副车架主体连接,副车架底梁的宽度小于副车架主体的宽度。本发明解决了副车架主体与通用底盘直接连接导致的通用底盘起重机整机空间布置困难、副车架主体截面宽度受限、副车架主体底板平面度受限的问题。
