Abstract

A wheel loader with a front bucket is capable of preventing spillage of load materials from the bucket, even without adjusting an angle of the bucket where a traveling state is switched from a flat ground to an inclined ground. The wheel loader has a bucket provided on the front of a vehicle body to scoop and discharge a work material, an inclination sensor for detecting an inclination angle θ of the vehicle body, and a controller configured to, in the case where a height position of the bucket is higher than a predetermined height and it is determined that the vehicle body is in a state of being inclined rearward, activate a bucket cylinder for causing the bucket to correct an angle of the bucket toward a front side where the bucket dumps in accordance with the inclination angle of the vehicle body.
