In a track whose rails are laterally and downwardly supported on the rail outer side and on the rail inner side via elastic intermediate inserts (4, 6) by longitudinal carriers underneath the head portion (3), the rails (2) extend at a distance above the track structure parts located therebelow. The longitudinal carriers at the rail outer side are first console ledges (5) which are part of a base plate (10) lying under the rails (2), and the longitudinal carriers on the rail inner side are secon...

An improved track system for movable apparatus for handling materials such as conveyor apparatus for distributing concrete mix and the like, comprises a plurality of track sections pivotally linked together, with each section comprising a tubular upper member mounted by means of struts on two parallel tubular lower members. The lower members are curved inwardly at one end and are beveled inwardly at the other end, so that two joined sections will mate and will form a substantially continuous out...

A track connector for track lighting mainly comprises a conductive coupler, an insulative shell and at least one flexible conductive shaft assembled to the conductive bushing corresponding to the coupling rail. The conductive coupler has a through hole and at least one coupling rail extending from one end of the through hole. The coupling rail is formed with a locking hole and a locking member is screwed into the locking hole to lock a track of the track lighting with the coupling rail. The trac...

A cushion track comprises an annular resilient driver having a track assembly mounted therearound. The track assembly comprises a pair of laterally spaced, articulated link assemblies closely coupling a plurality of ground-engaging track shoes together. Each link assembly comprises first and second parallel link members having retaining means extending transversely therefrom and releasably connected to each track shoe by at least one bolt. The retaining means comprises a flange integrally formed...

A track assembly for moving a vehicle which includes a track having lugs including both drive and guide portions on its inner surface. The guide portions substantially abut against the track rollers of the assembly. Such abutment maintains alignment of the track between those rollers so as to prevent it from moving from side to side and interfering with feeding of the drive portions onto the assembly drive sprocket. Further, the guide portions grab against the drive sprocket to maintain contact ...

A unitary flexible track for converting a wheeled vehicle into a tracked vehicle, the track being provided for mounting in longitudinal direction around at least two successive vehicle tire-wheel assemblies in movement direction of the vehicle, the track having an inner circumferential track surface provided to form a running surface for the wheels and an outer circumferential surface provided to form a running surface for the track with respect to the medium over which the track is to be displa...

The invention relates to an undercarriage, preferably for a crawler-mounted crane, comprising a crawler track which runs on a crawler carrier and which consists of base plates articulatedly connected to one another, with cams being formed on the base plates which laterally center the crawler track under the rollers, wherein two metal guide sheets which extend substantially over the length of the crawler carrier and which are engaged behind by holding plates arranged at the base plates of the cra...

A track cover adapted for use on an item of heavy construction equipment having at least one track. The track cover comprises an outside panel and a tread panel. The tread panel is preferably connected to the outside panel. The track cover also comprises an assembly for removably attaching the track cover to the item of heavy equipment. The track cover is adapted to cover at least a portion of the at least one track of the item of heavy construction equipment and retain dirt, rocks and other deb...

A track assembly having first and second hub assemblies that are operatively connected to a support frame by first and second attachment members, respectively. The first and second attachment members include resilient or movable mounts that are configured so that the track assembly can be attached to vehicles whose axles or wheel flanges are misaligned or have irregular rotational movement such as runout or wobble. The attachment members may be adjustably positioned relative to the support frame...

A curtain track, which includes a cylindrical metal profile track, the track having three longitudinal coupling grooves and one longitudinal sliding slot equiangularly spaced around the periphery thereof, and two end brackets for holding the track on a support wall, each end bracket having a mounting frame for fastening to a support wall and a coupling tube axially extended from one end of the mounting frame to hold one end of the track, the coupling tube having a longitudinal opening of width o...
