摘要： A novel system for providing for safe operation of railgear, that is, a set of guide wheels that allow road vehicles to travel on railroad tracks, based on the use of overload indicators installed on the suspension arm of each guide wheel to give operators a quick, visual representation of whether or not a guide wheel is overloaded.

摘要： A camera crane mobile base for carrying a camera crane includes a first powered remotely controllable steering system having first and second axle assemblies at a first end of a chassis. A second steering system including third and fourth axle assemblies is provided at a second end of the chassis. A first electrically powered remotely controllable propulsion system includes an electric propulsion motor connected to first and second axles in the first and second axle assemblies. A telescoping center post is pivotally attached to the chassis. An on-board hydraulic system may power the first steering system and the telescoping center post.

摘要： Described is a multi-mode transportation system with roads and monorails, and vehicles that can transform to travel on either roads, or monorails, or on both simultaneously. Vehicles move in mode 1 on the roads using road wheels that roll over pavement. Vehicles in mode 2 move on the monorails and are supported by rail wheels in contact with a top of a monorail. In mode 2, the vehicle is supported by side cylinders that stabilize the vehicle on the monorail. Vehicles move in mode 3 with support from both roads and monorails simultaneously. Monorail mount locations simplify the vehicle's transition between modes. Pivoting or other mechanisms for road wheels, rail wheels, or side cylinders facilitate vehicle design. The vehicle can optionally be connected to the Internet, and be part of a traffic control system or operate autonomously. Small scale models or computer models of these vehicle can be used as toys, for product development, prototyping, animation, competitive games, entertainment, or for education.

摘要： Disclosed are various embodiments for rear railgear, pivot links, and pin-off systems. An example assembly including railgear, an attachment frame, a mounting bracket, upper and lower links is provided. The rail gear includes a pair of guidewheels, an axle, and an axle saddle; the attachment frame can connect to the axle saddle of the railgear; the mounting bracket is configured to attach to a vehicle; the upper link pivotably connected to the mounting bracket; and the lower link pivotably connected to the attachment frame, where the lower link is connected to the upper link via a pivot pin. The railgear can be secured in either the deployed or stowed position using various interchangeable pin-off systems, including but not limited to: a manual pin-off system, an air operated pin-off system, and a cable pin-off system. The railgear can also be secured in the stowed position using an automatic mechanical lock system.

摘要： A manually manipulated apparatus supports a piece of equipment beneath a rail car gate of a railroad hopper car during maintenance or removal of the gate. The apparatus has a frame and a support frame attached to the frame. The support frame is selectively raisable and lowerable between a lowered position adjacent to the frame to a raised position extending upwardly above the frame. The support frame has an equipment engagement member which has an upwardly facing surface which is adapted to engage a downwardly facing surface of the equipment when the support frame is in the raised position.

摘要： A railroad trailer chassis comprising two or more road axles, two or more rail axles operable to be moved between first and second positions, and a work unit. The railroad trailer chassis is operable to be driven or towed in a road mode when the two or rail axles are in their respective first positions. The railroad trailer chassis is operable to be driven or towed in a rail mode when the two or more rail axles are in their respective second positions. The work unit is operable to perform one or more railroad maintenance or operation functions when driven in the rail mode.

摘要： A railgear guide unit assembly for a road vehicle comprises a pair of rail wheels coupled to an axle, a first pair of pivotal links, and a second pair of pivotal links, wherein both pairs of pivotal links are coupled to the axle at one end. The assembly further comprises a pair of railgear pressure mechanisms, wherein the railgear pressure mechanisms each comprise an outer guide assembly, an inner guide translatable within the outer guide assembly, and a spring coupled to a first end of the inner guide to provide a compressive force on the inner guide. One end of each of the pair of pivotal links is coupled to a respective inner guide such that a movement of the inner guides of respective railgear pressure mechanisms corresponds to a movement of the respective pair of pivotal links.

摘要： A ballast load device for increasing a tractive effort of a railcar mover having a coupler includes a side member and a bottom attached to the side member. The bottom is adapted to support a weight. A primary coupler is attached to the side member and is adapted to removably connect to the coupler of the railcar mover such that the railcar coupler may lift the ballast load device.
