A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks.A rolling component is typically pushed onto an axle and mounted directly on a railway carriage or locomotive, or indirectly on a bogie (in the UK), also called a truck (in North America). Wheels are cast or forged and are heat-treated to have a specific hardness. New wheels are trued, using … An outlook of the global rail wheel and axle market with reference to the automotive industry. The global industry is currently witnessing a period of stabilization as steady sales continue to sustain growth for suppliers and OEMs. However, an industry that is undergoing one of the biggest transformation, the future truly looks uncertain.
Locomotives (popularly called train 'engines') are the heart and soul of the Railway system. Locomotives give life to coaches and wagons which are otherwise dead hunks of metal which can best qualify as shelters during rains, converting them into trains. Locomotives work based on a really simple principle. Be it diesel or electric, locomotives are actually 'run' by a set of electric AC ...

Dec 23, 2019· What are the principal parts of an overhead traveling crane? Overhead crane equipment parts can be broken down into four main categories: -Power systems and motors-Electrical parts-Mechanical parts-Controls The principal parts of overhead traveling cranes are: bridge girders, end trucks, trolley with hoisting mechanism, an operator's cab or pendant control. A solid wheel of a railway vehicle (hereinafter "wheel") consists of three parts, as shown in Fig. 1. They include a hub, wherein an axle is inserted, a rim that contacts the rail, and a web that unites the two parts. The outer circumferential surface of the rim, which con-tacts the rail, is tread, and the projected part is flange.

Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of magnets, one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of friction.Along certain "medium-range" routes (usually 320 to 640 km [200 to 400 mi]), maglev can compete favorably with high-speed rail … Global Market Study on Rail Wheel and Axle: Sprouting Railway Network in Rural Areas of Emerging Economies to Remain Principal Factor Driving Adoption.

wheel-rail track assembly and decisions upon optimal design. 4. Conclusions On the basis of bibliographical surveys and researches conducted, the following conclusions can be drawn: - Most studies take into account both the contact area between wheel and rail track, and respectively the nearby areas, in the static load case. Typically a rail fracture is the result of a progressive defect, the propagation of which is related to the inherent residual stresses in the rail. Residual stresses are generated in railway rails first as a result of manufacturing processes. These may include hot …
