The invention relates to a track walking assembly and a circular track crane. The track walking assembly is used for running on a track assembly comprising an arc-shaped track and bearing a hoisting machine. The track walking assembly comprises paired track pressing wheel assemblies and a first trolley connected with the paired track pressing wheel assemblies, and each track pressing wheel assembly comprises a box-shaped wheel carrier which is rotatably connected with the first trolley and is provided with a first top plate, a first bottom plate and two first side plates, two groups of pressing wheels respectively and rotatably arranged on the two first side plates, positioned on the outer sides of the two first side plates, and configured to roll on the upper surface of the arc-shaped track so as to drive the box-shaped wheel carrier to move along the arc-shaped track and bear a load in the vertical direction, and the at least one limiting wheel rotatably arranged on the first bottom plate, positioned on the lower side of the first bottom plate and configured to roll on the side surface of the arc-shaped track so as to bear lateral load. According to the embodiment, the lateral bearing requirement of the hoisting machinery with larger tonnage can be met.

    本公开涉及一种轨道行走组件及环轨起重机。轨道行走组件用于在包括弧形轨道的轨道组件上运行,且承载吊装机械。轨道行走组件包括成对的轨道压轮组件和与成对的轨道压轮组件连接的第一台车,其中,轨道压轮组件包括:箱型轮架,与第一台车可转动地连接,且具有第一顶板、第一底板和两个第一侧板;两组压轮,分别可转动地设置在两个第一侧板上,且位于两个第一侧板的外侧,被配置为在弧形轨道的上表面滚动,以带动箱型轮架沿弧形轨道移动,并承受竖直方向的载荷;和至少一个限位轮,可转动地设置在第一底板上,且位于第一底板的下侧,被配置为在弧形轨道的侧表面滚动,以承受侧向载荷。本公开实施例能够满足较大吨位的吊装机械的侧向承载需要。
