What are the normal operating pressures/voltages?
The minimum operating pressure is a function of the pantograph mass and extension. However, all air raised, spring operated type pantographs are designed to operated below a supply pressure of 5 bar. Direct air pantographs usually require a minimum operating pressure of 7 bar, and the minimum pressures to raise are normally between 3.5 and 5 bar. Electric actuation is available for 24v DC and 110 v DC. Other voltages may be provided dependent upon requirement.
