English to Portuguese Tech/Engineering Mechanics / Mech Engineering crawlers - Shovels

Crawler Track - Crawler Shoes
Other engineered enhancements to the shoe design include:
An altered roller path geometry to reduce peak contact stresses and deliver increased resistance to shoe crushing and metal flow interference.

Guide Rails
Guide rails are replaceable castings or structural plates that are either pinned or welded to the top of the side frames.
Each guide rail is contoured to the shape of the shoe’s roller path, and guides the crawler track system over the top of the side frame as the shovel propels
