Drive track chain tension adjustment for track tension adjustment assembly having a slack adjuster of work machine

摘要

PROBLEM TO BE SOLVED: To solve a problem of having the possibility of shortening a service life in a driving crawler chain by keeping high tension for avoiding excessive looseness, causing a wear rate of the related components, and to provide a driving crawler chain having a longer service life by adjusting the tension. ;SOLUTION: A chassis assembly of a working machine is provided with the first diving crawler chain, the first hydraulic actuator mechanically coupled to the first driving crawler chain which adjusts the tension, the second driving crawler chain, the second hydraulic actuator mechanically coupled to the first driving crawler chain which adjusts the tension, and a looseness adjusting device assembly which adjusts actuation of the first and the second actuators.;COPYRIGHT: (C)2001,JPO
