Abstract: Apparatus and method for gravity-augmented preload of drive wheels in a monorail vehicle travelling along a guide rail with bearing and contact surfaces that are non-parallel with the gravity vector. The vehicle defines a pivot location against the bearing surface and a constraint point on the contact surface for engaging the rail on the bearing and contact surfaces, respectively. The vehicle is mounted so its center of gravity is at a rear longitudinal offset rrl from the pivot location and a vertical offset rvert from the guide rail. A force and moment balance thus created result in a normal load on a drive wheel engaged with the bearing surface at the pivot location, where the load value exceeds a standard normal load generated by the mass of the monorail vehicle alone.

Abstract: A transit system is provided for application within existing routes of travel infrastructures, travelling along the median strip and utilizing the air space over the median strip and above limited height roadway traffic and beneath overpasses and height limiting infrastructures. The transit vehicles are supported on or side mounted from trucks operating on an elevated structural beam trackway with a lower upwardly facing support surface, an upper downwardly facing support surface, and (on certain vehicles) an upper medially facing support surface. Variations of the structural beam mount under overpasses or along the ground surface, and are used in switching means for secondary trackways. The transit system's vertical dimension is reduced by the interrelationship of the trucks and structural beam trackway with the transit vehicles, and by placing the vehicle to the side of the structural beam and side supporting the vehicle from the trucks.

Abstract: A material handling system of the monorail and crane type is adaptable to carry relatively heavy loads and light loads through convenient structural modification using common component parts. The system is comprised of a double track 40 for heavy loads, formed of two track parts 54, 55 that alone are suitable for light-load applications. Carriers 42, 204 are comprised of drive heads 74 and idler heads 78, each with a single load support wheel 70, 71 or 70', 71'. A drive head 74, 74' and an idler head 78, 78' can be releasably interconnected in tandem by a load bar 206 to run along a single track, or in face-to-face opposition with wheels 70, 71 coaxial to form a drive unit 44 adapted to run along a double track. In the latter arrangement two additional heads, such as two idler heads 78b, 78c, are also interconnected in face-to-face opposition to form an idler unit 46 and connected in tandem with the drive unit 44 by a load bar 52.
Abstract: A modular rail member facilitates the translation of load-bearing carriages on an overhead track and comprises a vertical wall formed with two sections of different lengths which are spaced apart from and connected to each other by a flare having a vertical web. The two spaced-apart sections have ends curved in the same direction, and a vertical plane passing through the horizontal outer edges of the curved ends is set back relative to the vertical web.
Abstract: A guide rail and follower wheel construction for a monorail are disclosed. The monorail vehicle follower wheel has a radially directed, circumferential groove shaped to fit over a raised track portion, and the cross sectional shape of the wheel groove and the track over which it fits are such that the uppermost portion of the track contacts the radially innermost portion of the wheel groove. The wheel is mounted on the system comprising: a shaft and wheel includes opposed side-plates mounted for rotation on the shaft and a center disc mounted on the shaft between the side-plates and having a diameter less than that of the side-plates so as to form the groove. The side-plates are shaped to taper in diameter towards the center disc so that the uppermost track portion contacts only the disc. The side plates are rotatable on the shaft independently of the disc.
Abstract: To permit attachment of a suspended track without drilling of holes lfor installation and connection to support elements (25), the track has an upper hollow structural section (2), for example in essentially semi-circular shape with depending vertical sections (10), a similar lower hollow structural section (2) joined by a connecting web (3), the sections in the web are unitary, the web being of generally horizontal C-shape in cross section, with a generally vertical back portion (11), mutually converging or approaching forward portions (5) which are bent over themselves to form diverging wing portions (6) leaving a groove-like gap (4) therebetween, the ends (7) of the portions (5) and the diverging wing portions (6). Hanger elements (25) can be longitudinally positioned by clamping the hanger elements against internally positioned clamping bars or plates (27), permitting longitudinal alignment by relative sliding of the clamping bars within the C-shaped chamber.
