1. A lift gate system, comprising:
- a lift gate assembly including an actuator for actuating a lift gate, a main controller configured for controlling the actuator, and a wireless transceiver for receiving an operation command;
a wireless controller including an authorization controller configured for receiving authorization information from an operator and checking the authorization information against authorization control data to determine if the operator is authorized to operate the lift gate, wherein the authorization control data is remotely maintained; and
the wireless controller configured such that upon authorization of the operator by the authorization controller, the wireless controller wirelessly transmits an authorized operator command to the main controller;
wherein the main controller receives the authorized operator command and controls operation of the lift gate accordingly; and
wherein a lift gate operation authorized by the authorization controller of the wireless controller is performed only if one or more required conditions are satisfied, wherein said one or more required conditions includes one or more operational parameters of the lift gate.
