GCX-1000 track snow removal machine, being a scientific research tendering project of the Science and Technology Division, MOR of P.R.C., is won by KCRC. Winning a fully independent intellectual property right in key technologies, it is used to sweep snow on the surface of a railway track to ensure the failure-free operations of railway trains, or the high-speed trains in particular.

It is strongly adaptive to various working conditions, even during the night and in cold weather conditions with the super elevation of the working surface and a slope up to 180mm and 2000m respectively. With snow density of less than or equal to 250kg/m³, its working capacity can reach as much as 10000m³/h, at a working speed of 0~55km/h.

Besides, it can also serve as a track tractor, with the towing capacity up to 240t of freights on straight lines at a high self-propelled speed of 100km/h.

What is more, along with its development and production, GCX-1000 track snow removal machine not only makes breakthrough on multiple technological levels, including snow removal method for complex surfaces, the snow blowing technology for transponders and the key technology of a low-temperature cold-start, but also overcomes the difficulties in improving the efficiency and the machine’s towing capacity. 

TX-65 track sewage suction machine, a kind of track cleaning train independently developed by KCRC, acquires fully independent intellectual property rights in key technologies. It is mainly used to clean the railway ballast bed, especially ballast less track bed on the passenger dedicated line, and vacuum the dust, dirt particles, sand particles, micro pebbles and grinding powder and other sewage on the surface of the trunk line, bridge and tunnel ballast bed, to prevent damaging the precision sensors outside the train due to raising of the said sewage during a high-speed running of the train, thereby guaranteeing the train safety during its high-speed traveling. It attacks many key technical problems such as blowing consistency and air volume suction, the swinging control of blowing and suction devices, the high-degree integration of working system and structural optimization of the complete machine. The test shows that its utilization efficiency of wind blowing and suction energy reaches over 2 times above similar products abroad.

Track measurement machine is used to measure and calculate the relative amount of the fixed point from the road, track lifting volume, track lining volume, and the gauge, ultrahigh, mileage and other data, which meet the new lines, overhaul and maintenance work required tamping. At the same time, these data can be directly input to the tamping machines with the ALC system. The date are used as part of tamping machine control parameters to complete the track lifting and track lining.

Due to the reference point of measuring track lifting and track lining values is the fixed point----Geodetic coordinate system is a fixed point, The value of measurement is absolute value reference to the geodetic coordinate system. Based on these values using tamping machine for lifting, lining and tamping. The line can not only achieve the ride and keep the geometry, but also guarantee the relative to the fixed point position precision, so that the line back to the design state.

Track measurement machine can work in a straight line, curve and turnout ,to finish simultaneously the measurement of, versine, leveling, superelevation, gauge of mileage location. The working speed is no less than 2.5 km/h.

QJ-280 bridge inspection machine is a product for bridge, tunnel and aerial operation. The machine has the high-speed self-propelled function and can work independently.

QJ-280 bridge inspection machine’s jib can reach down to 13.5m below and up to 24.5 above the track surface, and levelly 21m away to the center of steel track in the working condition; The machine has the following features such as large working area, advanced technology, simple structure, reliable quality and high cost performance.

QJ-280 bridge inspection machine can meet the requirements of today's multiple sites, and has the features like short assistant time, maintenance of original ballast bed and the assurance for the operation of driving vehicle. If equipped with the corresponding accessories, it is able to weed, prune the shrubs and dig etc., so the bridge inspection machine can be the multi-purpose vehicle for the mobile inspection or maintenance.

HFX constant-tension catenary stringing machine can be used to erect the OCS wire and carrier cable separately or simultaneously to make the stringing tension change within the set value range and keep it relatively constant. It is equipped with both automatic and electronic tension control system, and has a stringing speed between 0 km/h and 6 km/h. The take-off function also enables it to be towed, with speeded up to 120 km/h. In addition to that, it can also lay 2 lines (carrier cable and wire) simultaneously so as to erect them at the same time, with the line diameter falling between 50 mm2 and 240 mm2. It is controlled on the operating board with the advanced electronic sensing technology and with electronic hydraulic devices, using a pre-set value of tension. In terms of travel control, it adopts PLC to control the flow rate of the travelling pump so as to give a gentle start and stop. With the automatic wire tracking capability, it may automatically move the wire coil rack based on the change in a wire outlet angle and therefore reduce the wire outlet angle and prevent any rigid point on the wire. It is also equipped with a tail offset device to lower the wire waste and save costs as well. Besides, it has an electrically controlled brake function, with the pre-set pressure of the brake cylinder being 0.3 MPa and adjustable based on the actual needs. Furthermore, it may be provided with high and low-speed travelling systems, knuckle boom cranes and working platforms, etc. in a customized way.
