The GMC-48K rail grinder is used for the preventive grounding and repair grinding of railway rails. It can eliminate rust, fatigue cracks, corrugations, spots, and fins on the track surface. The machine can operate in both directions, with an accuracy meeting the technical requirement for 300km/h high-speed lines, and it has an operating efficiency outdoing other similar products in the world.

The vehicle consists of three coupled cars, namely cars A, B, and C. Among them, cars A and B are motor cars and car C is a driven car. Cars A and B are provided with power packs, operating devices, driver's cabs and power bogies. Car C is provided with the meeting room, maintenance room, auxiliary generator room, operating device, tool kit and driven bogie. The three cars are permanently connected with connecting rods, without elastic buffers in the longitudinal direction. The vehicle is provided with a circular aisle for operators to inspect the working condition of the vehicle.

The electrical, hydraulic, pneumatic, braking, power transmission, and water systems of the vehicle are monitored by a main control computer, and operations are performed on the display screen of the executing computer. The grinding wheel driven by motor has excellent fire protection and economical maintenance performance. The vehicle is equipped with fire fighting and water sprinkling systems. Each grinding vehicle is equipped with a collector to collect ground dust. According to the requirement of the client, two vehicles can be coupled into a rail grinder with 96 grinding wheels.

MM-1000 metro milling machine is suitable for maintenance work for metro tracks. With one-off-milling this milling machine can remove the attrition (caused by long wave and short wave), flaws, fat edges, spallings etc. on the track surface. If it’s necessary, it’s possible to increase the feeding of milling units to accomplish one-off-milling on badly worn track surface.

MM-1000 is capable of rough milling, finish-milling and collecting scrap iron. It can rectify the profiles of cross and longitudinal sections of the track, so that the track surface could be smooth again. Furthermore, this machine has advantages such as high efficiency, low noise, low air contamination, working process free of water and no residual metal chips with the help of suction device. MM-1000 is especially adequate for tracks with high environmental requests, such as urban rail traffic and tunnel.

Adopting the technology of circumferential milling and equipped with the computer monitoring system, the rail milling and grinding machine effectively helps perform copy milling and grinding of the rail and allows reaching the desired effect at one time work. It has the following beneficial effects: extending the rail life after completely eliminating rail defects and failures; improving rail longitudinal regularity and cross-sectional profile quality (reducing rail wear, improving wheel-rail contact geometric state, lowering relative wheel-rail wear); saving rail maintenance and re-use costs; decreasing the working noise; optimizing the operational safety and efficiency of the railway network. It is featured by higher working precision, favorable effect, fewer limits, shorter setup time, smaller environmental influence, and lower working costs.

Rail milling and grinding machine and rail grinding machine have their respective advantages in terms of railway maintenance, and are strongly complimentary to each other. Specifically, in terms of preventive rail trimming, treatment of slightly-defective rails, rail trimming at the inner side of the line, and unusual rail profile grinding, the rail grinding machine is featured by high efficiency and flexible grinding; while in terms of profile restoration for rail maintenance and treatment of seriously-damaged rails, the milling and grinding machine has higher potential, as well as such advantages as enhanced efficiency, and eco-friendly working process featured by less sparkling and convenience for protection.

CMC-16 turnout grinding machine can be used for continuous grinding operation for various types of turnouts. Its precision can meet the technical requirements of 300km / h high-speed railway and it has the world advanced operation efficiency among the global similar products. The complete vehicle’s electrical, hydraulic, pneumatic, brake, power transmission and water systems are monitored by the host computer, and operation and running operation are shown on the computer screen of implementation computer. Grinding wheels are driven by the motor and have good fire protection and economical efficiency.

To meet the operational requirements of suburban railways, CMC-16 turnout grinding machine is equipped with fully functional fire, spraying system; each grinding trolley is equipped with a dust collector for collecting the grinding dust; the complete vehicle is equipped with the even measurement trolley to measure the even precision of railway before and after the operation. The manual horizontal railway profile measuring instrument is also equipped.

YHG-1200 mobile flash-butt welding machine provides the good environment for the field steel track welding and reduces the labor intensity of field operation, so that the field steel track welding quality meets or gets close to the level of plant welding, and can meet the seamless requirements of high-speed railway or passenger railway etc. The application of LR1200 welder meets the on-railway welding, off-railway welding and lock welding etc.; the rail pulling and aligning system is equipped on the left and right sides of complete vehicle to pull and align the steel track during the welding; the action system is hydraulically driven to the max. self-propelled speed of 100km/h; the frame is designed as the upper chord beam, provided with stable dynamic performance, reaching the max. coupling speed of120km/h; brake system adopts the reliable brake unit. It is the ideal welding machine for seamless tracks.

YHGQ-1200 NC gas pressure welding machine is a fully automatic welding machine with the working side centralizing, pressure-holding shearing, and pressure-holding normalizing, and the welding quality meets the requirements of Steel Welding standard TB/T1632-2005. The main technical levels and performance indexes reach or exceed the foreign the flash-butt welding machine like K922 and AMS60 etc, which makes the machine especially suitable for the plateau railway steel track welding. The machine is equipped with the special fixture for welding the 50, 60 and 75-track railways, and the fixture can be replaced according to the needs to achieve the unit welding, lock welding and folding lock welding for different types of tracks. The machine can carry out the welding not only for the new railways, subway and passenger railways, but also in the "roof" of existing railways, so it is the efficient and economic complete welding machine which is suitable for the actual construction of domestic railways and meets the quality standard.
