A track link for a machine track includes an elongate link body having an upper rail surface with an inboard peripheral edge and an outboard peripheral edge each formed upon a first link strap, a second link strap, and a middle section. The upper rail surface defines a longitudinal midline and at least one of the inboard peripheral edge or the outboard peripheral edge upon the first link strap and the second link strap is canted, in an inboard-outboard direction, to a longitudinal midline of the upper rail surface.

A machine track includes a track shoe having a first outboard edge and a second outboard edge, and a first set of pin lugs and a second set of pin lugs. A roller pad is positioned between the sets of pin lugs and includes a roller contact surface extending between a first roller pad end and a second roller pad end. The first roller pad end includes a relatively softer material, and the second roller pad end includes a relatively harder material that forms a trimming edge for trimming off interfering material of an adjacent track shoe in a machine track that is plastically deformed by way of roller contact with the adjacent track shoe during service.

The present invention provides a tracked wall climbing robot including a rack, two sets of track mechanisms and power components operating respectively in cooperation with the two sets of track mechanisms. Each set of track mechanism includes a track, a driving wheel, a tensioning wheel and a plurality of load bearing wheels, wherein the driving wheel, the tensioning wheel and the load bearing wheels are sleeved with the track, the tensioning wheel is used for tensioning the track, the driving wheel, the tensioning wheel and the load bearing wheels are rotatably arranged on the rack respectively through a driving wheel axle, a tensioning wheel axle and load bearing wheel axles, the driving wheel drives the tensioning wheel and the load bearing wheels to rotate through the track, the track is composed of a plurality of convex platforms, and attractive components are arranged in gaps between the convex platforms.

A machine system includes a roller frame and a roller assembly mounted to the roller frame. The roller assembly includes first and second clamping collars positioned upon a roller shaft and each including a lower and an upper collar section. Fasteners clamp the lower and upper collar sections to the roller shaft to form static seals. The clamping collars may be formed with splitlines to enable the clamping collars to deform so as to simulate interference fits with the roller shaft.

A pair of master track links has a first master track link including a first body. The first body defines a first bore and includes a first interface region including a plurality of teeth, and at least one tooth of the plurality of teeth includes a free end and a crown defining a crown width proximate the free end of the at least one tooth. The at least one tooth also includes a root disposed opposite the crown defining a root width, and the crown width is greater than the root width.
