ABSTRACT:
A light assembly specially mounted upon a lift truck load carriage at a position adjacent the bottom thereof and rearwardly of the forward end a load fork or other similar forwardly-extending load-engaging member, for forwardly projecting a shadow of the load-engaging member to aid the lift truck operator in determining the position thereof relative to a vertical array of stacked loads such as in a warehouse. A transfer mechanism is provided wherein the light assembly is removably mounted upon the carriage and, when the carriage is lowered beyond a predetermined position relative to the mast, the light assembly is transferred from its removable mount on the carriage to a fixed mount on the mast so that it does not follow the carriage downwardly. Upon elevation of the carriage above the aforementioned position, a reverse transfer takes place whereby the light is retransferred from the mast to the carriage and thus follows the carriage upwardly. The light assembly projects light forwardly in a substantially horizontal direction when on the carriage, but assumes a downwardly-tilted attitude after is has been transferred to the mast.
