Class Information
Number: 187/292
Name: Elevator, industrial lift truck, or stationary lift for vehicle > Having specific load support drive-means or its control > Includes control for power source of drive-means > With specific electrical component > For electric power source > With means for stopping vibration or bump start
Description: Control with means adjusting the functioning of the control* so as to prevent either (a) the oscillation of the load-underlying support surface during its travel or (b) any motion opposite to the intended direction of travel of the load-underlying support surface when it is leaving a landing*.
