Abstract: A snow removal system wherein snow removers located in remote locations can be monitored and controlled at a computing device. Data collected by sensors on the snow removal unit or data collected from a secondary source can be used to control the operation of the snow removers. In one embodiment, data regarding whether it is snowing at a particular location can be collected by moister sensors on the snow removal device and verified by on-line contemporaneous weather reports corresponding to the same location.

Abstract: A snow removal apparatus having a frame, a first snow removal device, and a second snow removal device. The first snow removal device is operably mounted to the frame for removing snow from a front end of the frame. The second snow removal device is operably mounted to the frame for removing snow from a region lateral to a front end of the frame. The first snow removal device and the second snow removal device enable snow to be removed from a width that is wider than a width of the frame.

Abstract: A method for the contactless scanning of a track bed profile extending perpendicularly to a longitudinal extension of the track, comprises the steps of simultaneously effectuating the scanning and a measurement of any deviation from a desired track level at a location of the scanning, recording the scanned track bed profile, and calculating an amount of ballast required for raising the track to the desired track level and for uniformly distributing the ballast in the track bed in dependence on the measured track level deviation and the recorded scanned track bed profile.

Abstract: A track maintenance machine comprises a machine frame, a track scanning unit adjustable connected to the machine frame and having flanged rollers for moving the track scanning unit along the track, a satellite receiver connected to the machine frame, the satellite receiver having an antenna with an antenna center, a measuring device for monitoring the position of the antenna center relative to the track scanning unit with respect to the following parameters: transverse track tilting (&bgr;), transverse track displacement (d) perpendicular to a longitudinal extension of the machine frame, and vertical distance (a), and a computer for a computed repositioning of the antenna center relative to a reference point of the track scanning unit.

Abstract: A universal trailer for transporting a variety of longwall roof supports for a longwall underground mine is disclosed, along with a method of using such a trailer. The trailer includes a wheeled, U-shaped frame that can be raised and lowered relative to the ground to lift and off-load a roof support. The trailer includes forward and rearward supports, either of which may be shiftable.

Abstract: A method and device to further remove snow left by a locomotive snowplow while enhancing traction and control of a locomotive or powered car. The snow removal enhancement method and device typically include a flap arranged to extend beyond a bottom edge of a locomotive snowplow over each rail. The flap loosens and removes residual snow, as well as other debris, left by the snowplow. The device handily removes snow while being constructed of the thinnest material possible.
