Abstract
The electrical collector unit (41) and the overhead conductor entrance (26) are designed so that four collectors (63, 64, 66, 67) can properly enter the conductor slots (18, 19, 21, 22) without manual assistance and with the vehicle, not shown, carrying the collection unit (41) traveling at near a walking speed. Two collector subassemblies (42, 43) are mounted on the vehicle, not shown, each of which carries two collectors and includes spring biased parallel links (73, 74, 76, 77) between a pair of pivot posts (71, 86), a guide roller (61) engageable with side walls (28, 29, 36, 67) of the entrance chute (26) and equalizer beams (134, 136) supporting the collectors (63, 64 or 66, 67).
