ABSTRACT:
The invention is concerned with an improved exhaust system for a lift truck. The lift truck comprises an engine within an engine housing, an exhaust stack, an operator seat, an overhead structure above the operator defining an operators compartment and a plurality of forks or other load engaging means controllably moveable vertically adjacent a forward end of the truck. The improved exhaust system comprises a first conduit affixed at an upstream end thereof to the engine to receive exhaust gas flow therefrom, the first conduit ending at a nozzle at a downstream end thereof. A second conduit of larger cross section than the first conduit is aligned to receive the nozzle and to accept gas flow therefrom along with ambient air and conduct said gas flow and air to said exhaust stack, which stack forms a vertical support for said overhead structure.
