The 450mm Tuffpad chain-on rubber pads (89x73x57mm bolt centres) are utilised when there are existing shoes bolted to the chains which have purpose-drilled holes to create the perfect fit. Chain-on rubber track pads, also known as Roadliners, are mounted to the track chain. They don't use a track shoe.
Chain on excavator track pads are commonly fitted to Komatsu and Hitachi mini excavators.
The chain-on style rubber pad is suited for applications where equipment is primarily operating on paved surfaces. They also suit other applications where surface protection in paramount, for example rail applications.
As there is no track shoe used for this style of excavator track pads, chain-on pads are not recommended for applications where it is desirable to be able to remove and refit the pads regularly depending on the project at hand.
