A railgrinder or rail grinder is a maintenance of way vehicle or train used to restore the profile and remove irregularities from worn tracks to extend its life and to improve the ride of trains using the track. Rail grinders were developed to increase the lifespan of the tracks being serviced for rail corrugation. Rail grinding is a process that is done to stop the deformation due to use
The grinding carriage design allows the machine to address a wide range of grinding head angles even in partially obstructed areas. The grinding heads are specially designed to grind points, stock rails, frogs and close to guard rails. Grinding is effective from 075 degrees gauge side and 045 degrees field side of the rail. A range of
Rail grinding is the cornerstone of virtually every railroad maintenance program. To maximize the life and value of rail assets, precision removal of fatigued metal, restoration of the rail head profile and removal of rail defects are the optimization goals of an effective rail grinding program.
A guiding mechanism forces the rail guiding discs to turn with the pivoting grinding unit. This stops the machine from slipping while maintaining a constant grindstone contact pressure and creating a true copy of the rail head and its profile over a pivoting range of 184.
The Class 1 heavy haul railroads of North America are using rail grinding best practices to ensure maximum returns on their investment in rail to their shareholders. AREMA Committee 4, Sub Committee 9, focus group consists of rail grinding managers responsible for implementing rail grinding best practice in North America. This group
Realize special shape of rail profile. Increase the usage time in the shortterm by making grinding amount over wear limit of steel rail head. For example, when the contact area reach 2030mm between rail and wheel, special grinding can remove the metal of wheel and steel rail, and grind inner side of rail gauge.
The Hatfield accident in the UK in 2000 was a wakeup call for railway administrations the world over. The derailment of an express passenger train with passenger fatalities was shown to have been caused by rolling contact fatigue RCF, in which tiny cracks in the rail head extended down into the body of the rail, eventually causing a break.
Subsequently, Colas expanded its Rugby depot with an extension to its maintenance shed to accommodate the sevenvehicle grinder. Loram has built two fourvehicle grinders and a sevenvehicle one after it was proven this was the most consistent method of removing fatigue cracks from the rail head.
Rail grinding is a process that is usually performed by railbound machines. These vertical and traction loading which cause the rail head to plastically deform. An unlubricated rail surface is subject to higher friction forces and therefore higher rates of plastic flow. As the contract stress exceed a certain limit, the metal at the near
Rail Head Grinding Machine. This universal machine is for all grinding requirements in new construction and maintenance of railways. Precise copying with patented rail guiding system Exact adjustable turning resistance on spindle handwheel Easy cup wheel change due to quicklock technology Guide wheel distance adjusts to different rail head
The grinding unit can be adapted with less effort to the trolley travelling winch of the respective crane type. Number of grinding motors 2 x 3. Power of grinding motors up to 7,5 kW per motor. Machinable rail width up to 140 mm rail head width. Machinable grinding angles 90 field side of rail 90 gauge side of rail
ANGM4.8 Petrol Rail Profile Grinder Honda engine 4.8kw Spindle RPM 4100 Grinding wheel 150mm x 65mm Weight 90kg Large profile grinder designed to grind the rail head or either side of the rail head by simply winding the handle at the front of the machine, the grinding mid section of the machine has 1000mm wheelbase Dimensions 1860mm x 570mm x 930mm
Network Rail has unveiled three new grinding trains costing 36m, which we be deployed across Great Britain to keep the track in good condition and provide passengers with a smooth, reliable journey. The multimillion pound trains, which remove small layers of metal from the railhead, represent a significant investment for Network Rail route services who worked with industry partners Loram
One machine. Two modules. Grinding with half the weight. ROGRIND HF Head is the first rail head grinding machine that consists of two parts.A small, powerful DC motor replaces the combustion engine generally used for grinding machines.
The rail grinder can be used for removing of rolling skin, the elimination of rail corrugations grooves and short waves on the rail head as well as for reprofiling of the rail head. The grinder RRGM 016 is efficient for working in the open and closed scopes of long rail sections for winning the transverse and longitudinal target profiles.
Rail grinders will typically use a coarser stone to work out all of the dips and wear found along the rail head and a finer stone to finish the work and return the rail to a nice, polished finish.
