MTS Pantograph Test System For trains to operate efficiently, the pantograph must maintain constant contact with trolley wires suspended from catenary systems. Yet these wires and their support structures exhibit different vertical stiffness along given sections. The catenary system zigzags in 30 to 100-meter intervals to prevent grooving.

The worktable guarantees a high reliability of the machine: it is a stable support even for large pieces. Operating unit supplied with 2,2 Kw electrospindle with ER25 morse spindle taper.
Yet these wires and their support structures exhibit different vertical stiffnesses along any given section. The catenary system zigzags in 30 to 100 meter intervals to prevent grooving. The force the pantograph applies to the wire must stay within a well-defined range (70N to 120N).
Place the horizontal and vertical placement lines of the Pantograph Placement Guide on the upper horizontal line and the vertical line of the pattern. (The etched lines of the
The SPV is a space saving vertical reach disconnector connecting the lower busbar to the upper one via the semi-pantograph arm. Horizontal rather than vertical separation means a space reduction of as much as 30%.
Introduction. Of all disconnector types, the pantograph disconnector design is the most compact.The application of pantograph disconnectors is especially useful for providing connection between busbars arranged at two different vertical …
Pantograph. Jiqin Wu, in Pantograph and Contact Line System, 2018. 2.1 Overview. Pantographs are a special devices mounted on electric trains to collect current from one or several contact wires. They consist of a pantograph head, frame, base, and drive system, and their geometrical shape is variable. Pantographs in operation are entirely or partially charged to build electric …

However, in these two works, only the vertical effect of the vehicle-track excitation on the pantograph-catenary interaction is considered. In reality, the rail irregularities, cross-wind [54] and flexibility [55] cause the motion of the car-body with six degrees of freedom (DOFs). Except for the vertical translation, the pitch and roll of the car-body definitely cause the vertical …
Farzad et al. attempted to reduce the vertical velocity of the overlap point at the anchoring section by implementing controllers that simultaneously operate on the pantograph and catenary. The pantograph strip currently has the problems of abnormal profile that negatively affect the variability of the PAC contact force and, as a result, the ...

Primary and secondary suspension (horizontal and vertical) Yaw dampers; Roof dampers; Pantograph dampers; Special applications; Pantograph Dampers. We have the only dampers designed for pantographs. Their fit, features, and performance characteristics are optimized to meet the unique requirements of pantographs.
In electric trains, a pantograph is mounted on the roof of the train to collect power through contact with an overhead catenary wire. The carbon-strip suspension of a pantograph, along which contact with the catenary occurs, is subjected to harmonic and stochastic contact-force excitations. In this paper, vertical dynamics of the carbon-strip suspension is studied with an …
The L200(/M) Lab Jack offers the same highly rigid dual-pantograph design as the L490 but in a smaller package size. The adjustment mechanism provides smooth vertical motion while supporting vertical loads of up to 50 lbs. The top and bottom plates each offer a generous supply of tapped holes and counterbores, adding to mounting flexibility.
As one of the three basic relationships of high-speed railway (i.e., pantograph–catenary relationship, wheel–rail relationship and fluid–solid relationship), pantograph–catenary system is the key to maintain the constant and reliable power supply for high-speed trains, as shown in Fig. 1a and b, which contains two main components—the catenary and the pantograph [1, 2].
