ABSTRACT:
A multiple function control for an electric lift truck which facilitates moving the truck while the load carriage is being raised or lowered. Two vehicles speeds in forward and reverse can be selected by means of a pair of pushbuttons (34, 36) located on the load carriage lift control handle (32), independent of the normal vehicle travel control (28). Circuit means are provided to prevent simultaneous selection of both forward and reverse drive motor directions and to prevent adverse results from simultaneous operation of the normal vehicle travel control and the pushbutton control.
