Abstract

A fork-lift truck having a chassis provided with a counterweight to balance the weight of a load carried by the mast and fork of the vehicle and an internal-combustion engine for propelling the vehicle, e.g. via a hydrostatic transmission, has the passages for the flow of cooling air to and from the engine formed directly in the counterweight and provided with flow-deflecting bends to serve as noise dampers. The noise at least emitted from the intake duct is thus partially damped by absorption of acoustic energy in the relatively massive counterweight.
