Abstract
PURPOSE: To prevent wheel-drop of the shoe belt by journalling guide wheels biasedly at the rear end with their center line directed outwardly with respect to the travelling direction.
CONSTITUTION: When a machine body 1 is turned rightwardly, a shoe belt 40 of a crawler A on the left side is curved arcuately with the outer side expanding outwardly with respect to the turning center Y. Guide wheels 30 go biting core metals successively which are arranged in parallel as the machine body travells. On the other hand, the shoe belt 40 of the crawler A on the right side, which is the turning center side, is curved inwardly of the machine body 1 in the front half thereof and deformed to expand outwardly in the rear half. The expanding direction of the rear half is in coincidence with the biasing direction in which the guide wheels 30 are journalled with their center line directed outwardly with respect to the machine body travelling direction for the purpose of preventing the wheels from dropping off.
