The invention provides a rotary table and a crawler crane, and relates to the technical field of engineering machine. The rotary table provided by the invention comprises a truss, wherein a front sealing plate and a rear sealing plate are connected to two ends of the truss correspondingly, a bottom plate is connected to the side face of the truss, an upper vertical plate and a rear transverse plate are connected to the side face, away from the bottom plate, of the truss, and the rear transverse plate is positioned between the upper vertical plate and the rear sealing plate. According to the rotary table and the crawler crane, the technical problems that the rotary table formed by using plates as main materials and welding the plates is large in design workload, low in material utilizationrate and low in bearing capacity are solved, and the purpose that a truss structure is used for replacing a plate structure to serve as a main stress structure of the rotary table is achieved.

    本发明提供了一种转台及履带式起重机,涉及工程机械技术领域,本发明提供的转台包括桁架,桁架的两端分别连接有前封板和后封板,桁架的侧面连接有底板,桁架的远离底板的侧面连接有上立板和后横板,且后横板位于上立板和后封板之间。该发明解决了以板材作为主要材料焊接而成的转台存在设计工作量多、材料利用率低以及承载能力低的技术问题,达到了使用桁架结构代替板材结构作为转台的主要受力结构的目的。
