Picture PB13 A side under view showing the clearance factor for the trolley shoes. |
Picture PB5 Another angled arial view |
Picture PB6 Getting under the wires. |
Picture PB3 An angled side arial view of the hanger with the trolleys below.
The trolley wire is soldered to the ears which are then inserted into the insulators and retained with wire
and glue. |
Picture PB4 A side arial view, if you look closely you can see the
tops of the ears appearing through the insulators. |
Picture PB7 Once again an arial view looking along the test bench. The
next hanger along has failed, hence its angle. |
Picture PB8 Corgi OOC London Q1 Trolleys pose under the
first section of live overhead, supported by twin line hangers, designed and built by Phil Bertram using similar
insulating principles as the prototype. The Trolleybuses are yet to receive their powered chassis or 'Faller'
steering units. The overhead wire used on this test bench is only 28 gauge soft brass wire. It is intended to
use the .30mm nickel silver wire produced by David Voice. |
