A roller mounting assembly for a ground-engaging track system includes a frame, and a roller block coupled to the frame and including a shaft support surface extending through the roller block. The roller mounting assembly further includes a damper resiliently deformable, relative to the roller block, to dampen loads transmitted between the roller block and the frame. Embodiments of a roller block assembly and a damping shim assembly are also disclosed.

This disclosure concerns wheels for industrial vehicles, including scissor lift vehicles and aerial platform vehicles. More particularly, this disclosure concerns a wheel fabricated with a substantially cylindrical wheel rim and a front face surface which includes a center hub section that is inwardly offset from the front edge by an amount and at an angle providing flexibility to recover from incidences that can damage the wheel.

A track-supporting roller assembly, according to the disclosure, for supporting a crawler track of a crawler chassis includes a bearing unit and a track-supporting roller rotatably coupled to the bearing unit. The track-supporting roller includes at least one supporting body made of plastic. The supporting body serves as a damper and prevents a metal-on-metal contact between track chain links of the crawler track and the track-supporting roller. The track-supporting roller assembly according to the disclosure ensures a reduced noise development in the crawler chassis. At the same time, it is possible to also reduce the wear of the track-supporting rollers to a considerable extent.

A deformable support wheel with a resilient chamber for a vehicular track-based system, is presented. The track-based support wheel comprises a central hub aperture portion configured to receive and operatively connect to a corresponding axle; a sidewall portion configured to concentrically surround an outer peripheral surface of the central hub aperture portion, the sidewall portion comprising a pair of radially-extending flanges that are laterally spaced apart from each other; and a deformable tire portion concentrically mounted on the sidewall portion. The inner surface of the flanges and an outer peripheral surface of the sidewall portion define a resilient chamber that provides a spacing between the outer peripheral surface of the sidewall portion and an inner peripheral surface of the tire portion. The support wheel structure minimizes lateral deformations caused by compression/shearing forces experienced during challenging environmental conditions by redirecting the deformations radially inward towards the resilient chamber.
