The invention discloses a chassis and a crane. The chassis comprises two main beams, bases and adjusting parts, wherein the two main beams are fixedly connected in a cross manner, the bases are arranged at the lower portions of the main beams, the main beams are supported on a supporting face by means of the bases, the adjusting parts are arranged between the main beams and the bases, the bases are connected with the main beams by means of the adjusting parts, the adjusting parts are used for changing distances between the main beams and the bases, and the adjusting parts adjust levelness of the main beams in a process of changing the distances between the main beams and the bases. According to the chassis, the levelness of the main beams can be adjusted by means of the adjusting parts by arranging the bases and the adjusting parts, and when the supporting face is uneven, leveling can be achieved by adjusting the adjusting parts of the chassis, so that the chassis is prevented from inclining.
本发明公开了一种底架及起重机,所述底架包括主梁,所述主梁为两个,两个所述主梁十字交叉固定连接;底座,所述底座设置在所述主梁的下方,所述主梁通过所述底座支撑在支撑面上;调节件,所述调节件设置在所述主梁与所述底座之间,所述底座通过所述调节件与所述主梁连接,所述调节件用于改变所述主梁与所述底座的间距,所述调节件在改变所述主梁与所述底座的间距过程中,调节所述主梁的水平度。本发明的底架通过设置底座和调节件可以通过调节件调节主梁的水平度,当支撑面不平整时,可通过调整底架自身的调节件来实现调平,从而避免底架倾斜。
