Crawler excavator
The invention relates to a crawler excavator which comprises a crawler chassis (10), a slewing bearing and a slewing platform (20), wherein the slewing platform (20) is rotatably mounted on the crawler chassis (10) through the slewing bearing; and the rotating diameter of the slewing platform (20) relative to the crawler chassis (10) is smaller than or equal to the length of the crawler chassis (10) in the advancing direction. According to the crawler excavator, the rotating diameter of the slewing platform relative to the crawler chassis is smaller than or equal to the length of the crawler chassis in the advancing direction, the slewing diameter of the slewing platform is effectively reduced, and operation of the excavator in a narrow space is facilitated.
本发明涉及一种履带式挖掘机，包括履带底盘(10)、回转支承和回转平台(20)，回转平台(20)通过所述回转支承可旋转地安装于所述履带底盘(10)上；其中，所述回转平台(20)相对于所述履带底盘(10)旋转的直径小于或等于所述履带底盘(10)沿其前进方向的长度。本发明中回转平台相对于履带底盘旋转的直径小于或等于履带底盘沿其前进方向的长度，有效减小了回转平台的回转直径，有利于实现挖掘机在狭小空间内进行作业。
