<p>A light assembly (28) is removably mounted, by a supporting member (54), upon a lifttruck load carriage (22) to provide a light source (32) positioned adjacent the bottom thereof and rearwardly of a load-engaging fork (26) thereby forwardly and substantially horizontally to project light and a shadow of the fork (26) which aids the lift truck operator accurately to determine the fork elevation relative to a load stack, especially when operating in a high-lift position. Upon lowering the load carriage (22) below a predetermined position the light assembly (28) is caught by and transferred to a fixed supporting member (60) on the lift truck mast (16,17) so that it is protected from contact with the floor. It is then also tilted so that light is projected downwardly. Upon subsequent elevation of the carriage (22) above the predetermined position a reverse transfer of the light assembly takes place from the mast to the carriage.</p> |
