description The utility model relates to the field of hoisting equipment, and discloses a crawler-type tower crane which comprises a plurality of groups of crawler walking mechanisms (1), a supporting platform (2) supported by the crawler walking mechanisms (1) and a tower crane chassis supported above the supporting platform (2), each group of crawler walking mechanism (1) comprises a pair of crawlers (12) which are connected with each other through a frame (11) and can be driven to run at a differential speed; and the supporting platform (2) is mounted on the corresponding frame (11) through a slewing mechanism (3) so as to allow the crawler walking mechanisms (1) to independently rotate relative to the supporting platform (2) by driving the crawler (12) to perform differential operation. The crawler-type tower crane can reduce internal stress generated in structural members such as a frame, is suitable for uneven road surfaces, does not need to occupy extra space during turning, and can turn in a relatively narrow fie
