A crawler vehicle, in particular hydraulic excavator, bucket wheel excavator or the like, has tensible crawlers guided around guide and crawler wheels, as well as track and return rollers, and provided with crawler links. At least one crawler scraper mounted on the frame of the crawlers extends into the area of the crawler links and has a pin-shaped axial projection movably guided in the axial direction in a sleeve secured to the travelling gear frame.
