Abstract
Abstract A compact material-handling loader including a vehicle body having ground supporting wheels thereon and having upstanding stanchions and arms pivotally connected thereto and supporting a loader bucket forwardly of the vehicle. An operator''s seat is disposed between the pivotal arms, and an engine is at the lower rear end of the vehicle body. The vehicle body defines a compartment above the engine, and a radiator is disposed in the compartment but neither the radiator nor the vehicle body extends up to the upper ends of the stanchions, so the low silhoutte and compact nature of the compact loader is retained while the engine is a water-cooled engine and has a water-cooling type of radiator connected therewith.
