Abstract
Provided is a control device for a wheel loader that is capable of improving the productivity of excavation work by reducing the work time required for the excavation work. A control deviceis a control device for a wheel loaderthat excavates a target by moving a vehicle bodyforward with rotation of wheelsto plunge a bucketinto the target. The control devicemoves the vehicle bodyforward with the bucketplunged into the target, and brakes the wheelswhen a rotational speed of the wheelsexceeds a predetermined threshold BS.
