Abstract
A vehicle may include a chassis, a motor, a pantograph, and a pantograph support structure. The pantograph may engage overhead wires and transmit electrical current to the motor. The pantograph support structure may include first and second leg frames, a lateral frame, and first and second bearing mount assemblies. The leg frames may include lower ends attached to the chassis. The lateral frame may be supported by the leg frames and disposed at upper ends of the leg frames. The lateral frame may support the pantograph. The first bearing mount assembly may be attached to the lower end of the first leg frame and may connect the first leg frame to the chassis. The second bearing mount assembly may be attached to the lower end of the second leg frame and may connect the second leg frame to the chassis.
