The invention relates to the field of engineering machinery, in particular to a base plate and a crane. The base plate comprises a first plate and a second plate which are arranged in a spaced mode, acontaining space is formed between the first plate and the second plate, the containing space is used for containing self-lifting supporting legs or forward-pulling supporting legs, an arc concave face is arranged on the side, facing the second plate, of the first plate, and the arc concave face is used for abutting against the self-lifting supporting legs or the forward-pulling supporting legs arranged in the containing space. According to the base plate and the crane, the bearing capacity can be improved, and the base plate lifting capacity can be enhanced.
本发明涉及工程机械领域,具体而言,涉及一种底盘和起重机;底盘包括间隔设置的第一板和第二板,第一板和第二板之间形成容置空间,容置空间用于设置自提升支腿或正扳起支腿,第一板朝向第二板的一侧设置有圆弧凹面,圆弧凹面用于与设置于容置空间的自提升支腿或正扳起支腿抵接。本发明的底盘和起重机能够改善其承载能力,有利于增强底盘起臂能力。
