PANTOGRAPH, METHOD OF ADJUSTING LIFT THEREOF, PANTOGRAPH, AND PANTOGRAPH MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method of adjusting the lift of a pantograph that can improve the lift property of a pantograph highly accurately, a pantograph, and a pantograph manufacturing method. SOLUTION: The lift of the pantograph is adjusted with the lift property of the pantograph calculated by pantograph lift property=aυ2-aυ4(1) the pantograph lift property can be obtained with high precision because a downward force is added that is proportional to the fourth power of the speed of cross-flow to the pantograph.
