A pantograph is a commonly used overhead suspension system for lamps and audio and video monitors in television studios. It is also used on a smaller scale in many photography studios. Using either motor driven cables or a spring system, the pantograph can be balanced so that a light touch can readjust the height of the load (usually a lamp).
The diamond-shaped, electric-rod pantograph of the Swiss cogwheel locomotive of the Schynige Platte railway in Schynige Platte, built in 1911 Cross-arm pantograph of a Toshiba EMU. A pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or trolley buses [1] to collect power through contact with an ...
Drafting pantograph in use Pantograph used for scaling a picture. The red shape is traced and enlarged. Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical ...
Along some sections on the northern part of the line an overhead line is also in place, to allow line M2's trains (that use pantographs and higher voltage, and have no contact shoes) to access a depot located on line M1. In depots, line M1 trains use pantographs because of safety reasons, with transition made near the depots away from revenue ...
Pantograph (four-bar, two DOF) Five bar linkages often have meshing gears for two of the links, creating a one DOF linkage. They can provide greater power transmission with more design flexibility than four-bar linkages. Jansen's linkage is an eight-bar leg mechanism that was invented by kinetic sculptor Theo Jansen.
The Brecknell Willis Low Height pantograph is one of the four standard devices in use on British railway locomotives and multiple units and is a development of the standard Brecknell Willis High Speed pantograph. The Low Height pantograph is suitable for speeds up to 160 kilometres per hour (99 mph).
Stone Faiveley pantograph in raised position on British Rail Class 86 25 kV AC Bo-Bo locomotive No.E3146 (later 86 017), London Euston, April 1969. France remained as Faiveley's core market. During the 1970s, the company introduced new corail coaches for the SNCF and provided equipment for a new generation of subway trains , the MF77.
The result was a pantograph that allowed the long horizontal bars to be rotated into the vertical to point upward at an aircraft, sighting along the upper bar. [ 1 ] A final piece was a separate vertical bar connected to the two horizontals and pivoted in the same way so that it remained pointing vertically as the horizontal bars were rotated.
