Abstract

A supplemental remote control system for a materials handling vehicle includes a wireless remote control device that is useable by an operator interacting with the materials handling vehicle. Actuation of a travel control on the remote control device causes a wireless transmitter on the device to transmit a travel request to the vehicle. The remote control system further includes a receiver for receiving transmissions from the wireless transmitter at the vehicle and a controller at the vehicle in communication with the receiver for implementing the travel request. The wireless remote control device further includes an input component, wherein actuation of the input component causes the wireless transmitter to wirelessly transmit a second type of request to the receiver on the vehicle requesting the controller to implement a second vehicle function other than to advance the vehicle.
