The invention discloses a frame and a crane. The frame comprises a connecting cross beam, a frame longitudinal beam and a suspension oil cylinder support, the frame longitudinal beam comprises a frame left longitudinal beam and a frame right longitudinal beam, and the frame left longitudinal beam and the frame right longitudinal beam are arranged in parallel at an interval; the suspension oil cylinder support is arranged on the outer side of the longitudinal beam of the frame, and the suspension oil cylinder support is detachably and fixedly connected with the suspension oil cylinder; and the connecting cross beam is arranged above the frame longitudinal beam and is detachably and fixedly connected with the suspension oil cylinder support. An original connecting cross beam welded to the lower portion or the lower portion of the frame front section is omitted, the assembly type connecting cross beam is provided, transmission and counteracting of force of the left suspension oil cylinder and the right suspension oil cylinder are facilitated, the torsion resistance of the frame front section can be improved, the local stability of the front section can be improved, and meanwhile the assembly requirement of an engine can be met; the design space between the engine bottom and the axle is increased, the engine height can be reduced, the transmission shaft included angle is reduced, and arrangement of a transmission system is facilitated.

    本发明公开了一种车架及起重机,包括连接横梁、车架纵梁和悬挂油缸支座;车架纵梁包括车架左纵梁和车架右纵梁,车架左纵梁和车架右纵梁间隔平行布置;悬挂油缸支座布置于车架纵梁外侧,悬挂油缸支座与悬挂油缸可拆卸地固定连接;连接横梁布置于车架纵梁上方,连接横梁与悬挂油缸支座可拆卸地固定连接。本发明取消原焊接于车架前段下部或下方位置的连接横梁,提供装配式连接横梁,不仅有利于左右悬挂油缸力的传递与抵消,还能增加车架前段的抗扭转性能,提高前段局部稳定性,同时又能满足发动机的装配需求,增加了发动机底部与车桥间设计空间,可降低发动机高度减小传动轴夹角,有利于传动系统的布置。
