Claim:
A loading machine comprising: a frame supported on front and rear drive axles respectively provided with front and rear drive wheels; a loader arm having one end pivotally mounted to said frame for pivoting vertically about an axis extending parallel to said front and rear drive axles and having a second end mounted to a loader tool by way of a tool holding fixture; a hydraulic arm tilt cylinder being cooled between said frame and said arm for selectively raising and lowering said arm; an engine mounted on said frame and including a control device for controlling power output of said engine; a drive train coupled between said engine and said front and rear drive axles and including a transmission; an overload protection device for the drive train, the device including a sensor arrangement including at least one load sensor for sensing a load condition occurring on at least one of said arm, tilt cylinder, front axle and rear axle, and for generating a load condition signal representing said load condition; a control unit coupled for receiving said load condition signal and for determining whether said load condition signal is such as to indicate an overload state for the drive train and for generating a control signal when said overload state is indicated, with said control signal being coupled to said control device of the engine, which operates to reduce engine power output.
