Patent number: 4848481Abstract: To avoid skidding of the driving wheels of a tractor (1) which runs on tires and which is fitted with hydraulic lifting devices (3, 4) on which are mounted working tools (35, 45) which are buried in the ground (in this case ploughs), the apparatus includes detector structure for determining the force for forward movement of the tractor, comparing that force to a reference value and producing pulses of less than one second, for alternately raising the two lifting devices (3, 4), the amplitude of the pulses being proportional to the excess of the forward movement force, up to a limit amplitude of centimeters approximately. The pulses are too short for the tools (35, 45) to lift with respect to the ground and the amplitude of the raising movement appears as squashing of the tires, which increases grip in order to overcome the excess of forward movement force.Type: GrantFiled: December 11, 1986Date of Patent: July 18, 1989Assignee: Jacques BidonInventors: Jacques Bidon, Francois Degraeve

The boom lift attachment is designed to rotate the mobile connector carrier relative to the lift truck in order to accurately position the mobile connector carrier in a working space between the trailers and to move the carrier into locking engagement with the front trailer, prior to rearward movement of the front trailer to engage the kingpin of the rear trailer with the mobile connector carrier.Type: GrantFiled: June 20, 1988Date of Patent: June 13, 1989Assignees: Homer J. Beliles, M. Dale CantrellInventors: Homer J. Beliles, M. Dale Cantrell, Carl H. Sanders

Patent number: 4813695Abstract: A multi-axle road vehicle has an equalizing resilient suspension for equalizing the load over the axles of a multi-axle set. The suspension is itself carried on a suspension subframe that is in turn mounted on the vehicle to pivot about a transverse, horizontal axis. The use of a pivoting subframe provides for equal axle loading over a much wider range of road conditions. The suspension system is especially suited for application to the "B" train multiple vehicle configuration, where the common suspension will be mounted on a subframe pivoted to the lead vehicle and carrying a fifth wheel for the following vehicle.Type: GrantFiled: December 23, 1987Date of Patent: March 21, 1989Assignee: Altank Industries Ltd.Inventor: Roy C. Reid

Patent number: 4809636Abstract: A construction transportation assembly comprising a buoyant general construction component having eight corner portions defining a rectangular parallelpiped locus with a length and a width generally corresponding to those of an ISO standard freight container, and two specialty components mounted on top of the general component laterally adjacent each other and lying within the length and width of the locus.Type: GrantFiled: October 12, 1987Date of Patent: March 7, 1989Assignee: Robishaw Engineering, Inc.Inventors: Paul A. Robishaw, Reginald B. Page

Patent number: 4794867Abstract: The invention relates to an omnibus which is suitable for train formation, can be driven independently and can either be freely steered or guided on tracks. In order not to disfigure the omnibus front by protruding coupling devices, and to be able to carry out the coupling operation without an assistant from the driver's position of the particular omnibus to be coupled, it is envisaged that at least the front coupling is designed in the form of a bar which can be extended or retracted under remote control. In the extended state, the bar can be moved under control within limits and can be engaged with the counter coupling head of the omnibus in front. The coupled omnibuses of a train are simultaneously and uniformly controlled from the driver's position of the first omnibus with regard to all their traction and braking functions.Type: GrantFiled: January 4, 1988Date of Patent: January 3, 1989Assignee: Daimler-Benz AktiengesellschaftInventor: Walter Titz

Patent number: 4768802Abstract: A steerable dolly for a truck trailer resting thereon comprising a steering linkage to turn the dolly wheels relative to the dolly frame, the linkage including an engagement with the trailer that senses the yaw articulation angle of the trailer relative to the dolly frame and causes the linkage to steer the dolly wheels in response to the yaw articulation angle. The steering ratio of the dolly wheels to the yaw articulation angle is a function of the dolly tow bar length for a B-Dolly configuration, the rear overhang of the towing vehicle and the wheel base of the trailer resting on the dolly fifth wheel. The steering ratio may be adjusted by adjusting the effective length of one of the links in the steering linkage.Type: GrantFiled: May 22, 1986Date of Patent: September 6, 1988Assignee: The Regents of the University of MichiganInventor: Christopher B. Winkler

Patent number: 4766818Abstract: Novel highway trailers can be mounted on railtruck assemblies to form a train of highway trailers, the railtruck assemblies including a conventional railtruck which supports a novel intermodal adaptor. The novel highway trailers include a forwardly extending tongue and coupling structure at the rear to which may be secured the tongue of a following trailer and the intermodal adaptor of a railtruck assembly. The intermodal adaptor is mounted on the center plate bowl of the bolster of the railtruck. The adaptor includes a locating assembly adapted to be received within the coupling structure of a leading highway trailer, which locating assembly permits the leading highway trailer and intermodal adaptor to become aligned with each other upon relative movement.Type: GrantFiled: August 26, 1986Date of Patent: August 30, 1988Assignee: Railmaster System, Inc.Inventors: Harry O. Wicks, Monte P. Riefler

Patent number: 4741273Abstract: A semi-trailer and its releasable coupler for use in rail transportation of intermodal containers and other adaptable cargo. That capability is met by structuring a centered longitudinal beam to the cargo deck and fitting it with the releasable coupler of this invention, permitting the trailer to be one of an infinite number of like trailers joined end to end as a train, the flexibility and longitudinal strength gained through the beam/coupler assembly. Ease of releasing and engaging a trailer from or to the train is made practical by this coupler and the front end supports, the latter having ability to raise and lower the front section of the trailer and separating the coupler segments.Type: GrantFiled: October 7, 1985Date of Patent: May 3, 1988Inventor: Clyde L. Sherwood

Patent number: 4740007Abstract: A cargo-carrying vehicle including a forward cargo-carrying body; a rearward cargo-carrying body; and an apparatus for locking the forward cargo-carrying body and the rearward cargo-carrying body together so that the forward and rearward cargo-carrying bodies can be backed as one unit. In some embodiments, the apparatus can provide at least three spacings between the forward cargo-carrying body and the rearward cargo-carrying body.Type: GrantFiled: March 4, 1987Date of Patent: April 26, 1988Inventors: David E. Lutz, David W. Lutz

Patent number: 4685399Abstract: A bogie for use in an intermodal transport system has wheels rotatably mounted about two spaced parallel axes, and a coupling device (33) for securing the bogie to a wheeled rail wagon, one end of which is supported on the bogie. The coupling device (33) cooperates with a coupling device, provided at that end of the wagon, which are adapted to couple the wagon to another wagon or to a locomotive in normal use of the wagon.An intermodal transport system comprises such a wagon; a drive device, e.g. a tractor for road and a locomotive for rail; and a bogie provided with road wheels or rail wheels of a gauge different to that of that of the wagon, in accordance with the mode of transport over which the wheeled wagon is to be transported.Type: GrantFiled: May 29, 1985Date of Patent: August 11, 1987Inventor: Dorian R. W. Baker
