A shroud for a track shoe grouser protector includes an elongate shroud body having weld holes formed in a first shroud leg and a second shroud leg attached to a base in the elongate shroud body. The shroud may have a fore to aft profile having the form of a flat-crowned arch with the shroud legs flared outward to form a grouser opening for positioning the shroud upon a track shoe grouser in a ground-engaging track system. An inventory of shrouds includes long shrouds and short shrouds positionable in a plurality of different assembly combinations to shield grousers in track shoes having a range of sizes.

The invention is about a crawler driving device, which includes a main frame, a rotary driving wheel designs over the main frame, idler wheels design at both ends of the main frame, as well as multi-pair interval roller wheels mounted at the bottom of the main frame for fore-after driving direction, and crawlers sleeved on the outside of the drive wheels, the idler wheels and the roller sets. The driving wheel of the current invention and the tooth block inside the crawler belt are in meshing structure, so as to drive the crawler belt to rotate. The roller wheels at the bottom can swing up and down during the driving, and supporting the system as well. the roller wheels swing up and down with the rotating shaft in the middle of the mechanical balancers as the fulcrum. In case of uneven terrain, the four sets of roller wheels at the both ends of the balancer can be force-buffered at the same time, so as to ensure the stable ground drive and keeping the vehicle smoothly moving. The idler wheels guide direction, and the tensioning mechanism realizing the tension adjustment between the track and the wheel under the action of the hydro-cylinder.

A track pad includes a shoe member that has two bottom voids extending upwardly from the ground engaging surface of the shoe member, and which form a central support pillar having a serpentine surface laterally on side of the central support pillar, and another serpentine surface laterally on the other side of the central support pillar. The two bottom voids form oval perimeters at the ground engaging surface.

A ground-engaging track shoe in a track joint assembly includes a shoe plate having bolt holes extending through a middle plate section between a planar link-bolting surface and a ground-contact surface. A weight relief channel is formed in the middle plate section upon a link-bolting side of the track shoe, and extends inwardly from the planar link-bolting surface. The weight relief channel is arranged between a forward bolt hole set of the bolt holes and a back bolt hole set of the bolt holes in a fore-aft direction.

A ground-engaging track shoe includes a shoe plate having link-side fixturing surfaces and ground-side fixturing surfaces. The link-side fixturing surfaces and the ground-side fixturing surfaces are raised in profile relative to a link-facing surface and a ground-facing surface, respectively. The fixturing surfaces enable a fixture to clamp the track shoe for support during processing, enabling improvements in maintaining portions of the track shoe flat and reducing part to part variation.

Provided herein is a protective rubber track shoe for an excavator, which includes a first-stage rubber mix and a second-stage rubber mix. The first-stage rubber mix consists of a natural rubber, a chloroprene rubber, a butadiene rubber, a styrene-butadiene rubber, a tire reclaim rubber, a 120-mesh rubber powder, zinc oxide, stearic acid, an anti-aging agent 3100, an anti-aging agent CTU, paraffin wax, an intermediate super abrasion furnace carbon black and an aromatic oil. The second-stage rubber mix consists of the first-stage rubber mix, sulfur, an accelerator CZ and an auxiliary agent.

A device for attaching a crawler track member of a crawler track to a crawler belt of the crawler track having a press-in element and a connection element, wherein the press-in element comprises a main body having a continuous opening, wherein when the press-in element is arranged on the crawler belt, the connection element for connecting the crawler track member to the crawler belt engages through the continuous opening. The device is characterized in that the press-in element comprises multiple holding elements projecting from the main body, wherein the holding elements are configured in such a manner that when they are arranged on the crawler belt they penetrate multiple material layers of the crawler belt, in that the holding elements displace material of the material layers, in particular transversely to the penetration direction.
