Abstract
A wheel loader configured to reduce the traveling distance required for a raise and run operation, and reduce fuel consumption includes: an engine; a torque converter; a forward and reverse switch; a stepping amount sensor; an operation amount sensor; and a controller. The controllerdetermines whether a specific condition for specifying an operation of the lift armin an upper direction during forward travel of the vehicle body, on the basis of a forward and reverse switching signal, the stepping amount on the accelerator pedal, and a pilot pressure Ti pertaining to the lifting operation amount for the lift arm. When the specific condition is satisfied, the vehicle speed is limited by reducing the maximum rotational speed of the enginein response to increase in the pilot pressure Ti.
