摘要:
A dual use roadway or railroad travel vehicle such as a railcar mover (10) which includes an inner set (24) of wheel assemblies (28, 30) designed for alternate roadway or rail travel, together with fore and aft rail wheel assemblies (32, 34) which may be alternately retracted for roadway travel or lowered for rail travel. The wheel assemblies (32, 34) each have a pair of rail wheels (36, 38) mounted spindles (48) so that the rotational axes A of the wheels (36, 38) are oriented at an oblique angle &agr; of less than 6° relative to the horizontal H; this wheel orientation, together with a rail wheel geometry including a rim surface (40, 42) parallel with the associated rotational axis A and a reduced radius of curvature R between the rim surface (40, 42) and the flange (44, 46), significantly decreases the problem of rail wheel climb encountered with conventional movers (10), while also reducing flange wear.

A ballast distributing railroad car has a number of ballast hoppers, each with a selectively operable hopper discharge control member which is operable to selectively drop material from the respective hopper either inside of or outside of the rails of a railroad track. The railroad car also has a pair of ballast distributing blades pivotally attached beneath it, either between the hopper discharge control members or one at either end of the car, with the blades being mirror images of each other. Each blade and each hopper discharge control member can be selectively operated via an independent hydraulic actuator. A remote control radio transmitter and car mounted receiver provide for remote, individual and selective control of hopper discharge control members and blades on a car.

The present invention relates to a snow and ice melting device (10) comprising a road transport vehicle (12) and a railroad track transport vehicle (14) mounted on a common road transport vehicle chassis (12I). Upon the railroad track transport vehicle (14), a melter (16) is mounted on a melter rotator (16C) functioning to rotate the melter from a rearward (road transport vehicle (12) frontward) direction which is utilized as a propulsion device to a frontward (road transport vehicle (12) rearward) direction which is utilized for melting snow and/or ice. The melter (16) has a melter lift (16E) such that a user can angle the melter (16) to a desired position.

A loading wagon (1) for the transport, storage and discharge of bulk material has a wagon frame (2) supported on on-track undercarriages (3) and a wagon body (5) connected to the wagon frame, there being arranged in the base region of the wagon body a base conveyor belt (7) having a drive (11). Provided adjacent thereto is a transfer conveyor belt (8) which projects over the end of the wagon frame, has an elevated discharge end (9) with respect to the wagon frame (2), and which is provided with a drive (12), with a storing or transporting direction (31) running from the base conveyor belt (7) to the transfer conveyor belt (8). An outlet opening (14) for discharging the bulk material onto the track is provided beneath the base conveyor belt (7). The drive (11) for the base conveyor belt (7) or the transfer conveyor belt (8) is designed for selective operation in the first transporting direction or in a second transporting direction running in the opposite direction thereto.

The invention comprises essentially a first car (1) resting on a bogey running on the track to be replaced, and a second bogey (3) moving during the work cycles with the aid of two auxiliary devices (5, 6) above the old cross-ties (4) without rails. It also comprises a work unit for removing the old rails, a unit (8) for the old cross-ties (4) and a unit (10) for laying new cross-ties (2). The auxiliary devices (5, 6) are two retractable translation devices arranged so as to be able to move on the cross-ties (4) without rails and are disposed on either side of the second bogey (3).
摘要:
A railcar transport for use with a truck tractor towing means comprising a trailer having an elongated rectangular frame having the rails thereon located on the longitudinal side frame members, having a railcar ramp secured to one end thereof, having a power winch mounted on the other end thereof to pull railcars thereon, having a rail alignment mechanism on one end the trailcar ramp mounted between the rails thereon, and having railcar ramp articulation means which are mounted either at the ramp pivot point or therebelow.
摘要:
A convertible rail-highway car moving vehicle is constructed by a tractor having a front end and a rear end. A pair of rubber wheels, which may take the form of rubber-tired wheels is associated with the front end of the tractor. At least one pair of flanged wheels which can be raised and lowered is associated with the front end of said tractor. One further pair of flanged wheels is associated with the rear end of the tractor. One pair of upwardly and downwardly moveable rubber wheels, which may be rubber-tired wheels, is associated with the rear. During operation on rails, the front end of the tractor is raised and the rear end is lowered, while in the terrain driving mode the front end is lowered and the rear end is raised.
