Abstract

A lift truck includes a secondary rechargeable energy storage device on a vertically movable platform that is separate from a primary rechargeable energy storage device on the lift truck's main tractor unit. Wires or hoses for transfer of power or controls between the main tractor unit and the platform are reduced or eliminated. The quantity of energy stored in the secondary rechargeable energy storage device is sufficient to power platform electrical loads for a predetermined amount of time until the platform is lowered. When the platform is lowered, the secondary rechargeable energy storage device is recharged by the primary energy storage device.
