Heavy Duty Track Link Group
Description
The link assembly is driven by the sprocket and final drive. It supports the weight of the machine, provides a rail for the machine to travel on, and provides a place for the track shoes to attach.
Features
Cat® Sealed and Lubricated Track (SALT) seals lubricant inside the undercarriage system and keeps abrasives out. It eliminates internal pin and bushing wear, reducing maintenance costs and downtime while increasing service life and serviceability. Combined with a track design matched to the machine and working environment, SALT provides a versatile undercarriage configuration for a wide range of ground conditions.
