ABSTRACT:
In an endless track for crawler type vehicles, a plurality of identical, reversable track links are articulately interconnected in transversely spaced pairs into an endless chain by sealed pivot assemblies including readily replaceable hardened wear inserts at points of greatest fatigue. Track shoes consisting of two selectively independently replaceable plates are secured to and extend between the corresponding outwardly bowed rail surfaces on the transversely spaced links of each link pair for operation until wear of the plates and/or links necessitates on site, life extending maintenance initially to individual parts and eventually to the entire endless chain. In the latter event, the entire endless chain is serviced by disconnecting one master pivot assembly to take the chain off the vehicle, ndividual parts and eventually to the entire endless chain. In the latter event, the entire endless chain is serviced by disconnecting one master pivot assembly to take the chain off the vehicle, ndividual parts and eventually to the entire endless chain. In the latter event, the entire endless chain is serviced by disconnecting one master pivot assembly to take the chain off the vehicle, removing the track shoes from the unworn rail surfaces, securing the track shoes to the corresponding worn rail surfaces on the other side of the articulately interconnected track links, and then reassembling the chain on the vehicle by resecuring the one master pivot assembly to reform the endless chain with the unworn rail surfaces about the vehicle rollers and drive sprocket for continued operation with substantially the same parts.
