To supplement to its purely rail-machining role, in the future the grinding train will also be a diagnostics vehicle. Equipped with measuring and testing technology, the HSG-2 will log the condition of a rail during every pass and in so doing compile a database for our revolutionary and highly efficient maintenance concept, Smart Maintenance.

Presentation of a rail grinding vehicle SF50. During this event the new development of the SF50 which was conceived for and with Bremer Straßenbahn AG was presented for the first time to a larger group of experts. All attendees were able to exchange views and take along many new ideas for their own operations and tasks.
The Harsco Rail by Möser road/rail-grinding machine RO-V 149 is the ideal grinding vehicle for tram and metro networks. It fulfils all requirements for rail grinding in metropolitan areas and is suitable for reprofiling, removing corrugation and rolled skin and for contact grinding.
Used with SBG100 Portable Rail Grinder, Battery-Powered Automatic shut-off protects vehicle from excessive discharge of vehicle's battery Patented voltage-booster circuitry charges the battery whether the vehicle's motor is running or not for more flexible use and reduced downtime
Rail Bound and Hi-Rail vehicles. In addition, the Contractor's grinding equipment must be equipped with a spark arrester system (grinding process), spare rail wheels, and a fire suppression system. 4.0 Required Submittals The Contractor's grinding machine shall take real- time rail profile measurements and compare them to
An experienced Loram technician conducts the profile and surface inspections using the hi-rail vehicle-based measurement system to automatically determine optimal grind angles, passes, patterns, and rail grinder speeds to ensure the proper rail profile is achieved for both main line and specialty track work.
A typical rail grinder doing work along a heavy, freight main line in the United States is not a singular unit but an entire train staffed with several workers. It includes the lead locomotive, which pulls the grinding equipment and crew quarters.
A railroad track rail grinding car having both vertical and horizontal grinding stones, with the horizontal stones being individually positionable to contact selected areas of a rail head profile and with the vertical stones being mounted on a flexible beam that can be bent to adjust the grinding path of the vertical stones. Both vertical and horizontal stones are surrounded with …
1) A railgrinder is more likely to be a train, not a single vehicle. 2) "before they need to be replaced" is tautology. 3) "Many forms are known" is completely uninformative. 4) A simple angle grinder might be used for a localized touch-up but is unsuitable for reprofiling of continuous length of rail which is what a railgrinder usually does.

The final rail-grinding car with the open abrasive belt is shown in Figure 6. Its design parameters are listed in Table 1. Like current facing grinding car by the abrasive wheel, the proposed rail-grinding car here is designed to own two statuses: the hanging state without grinding and the working state with grinding.
The rail milling train renews track by grinding away the damaged top layer of steel on the rail. It has wheels with hundreds of cutting tips, which spin to shave off small pieces of rail. Doing this slowly means the train consistently shaves off all the defects as it passes. A polishing head then ensures the renewed rail gives passenger and ...
Since 1994, Windhoff has supplied various types of rail grinding vehicles (new grinding vehicle, refurbishing older vehicles for grinding, e.g. old trolley cars, grinding trailers, etc.), and they are used for routine and special grinding jobs as part of a rail track maintenance programme.

The Rail Grinding Vehicle market is moderately consolidated, with several global and regional players catering to the needs of a large consumer base. The local companies can manufacture effective yet affordable grinding vehicles with customized specifications for the regional customers, intensifying the overall market competitiveness.
The profile of the rail head is similar to an arc shape, but the actual grinding (grinding wheel type) is to divide the rail head into different areas according to the angle, that is, the rail head profile is regarded as composed of line segments divided by angles, and the position that needs to be ground corresponds to is a certain angle.
