Abstract
Official abstract text for this publication.
A wheel loader is provided with a cab, an air conditioning unit, a cooling fan which has a condenser and a compressor, an air conditioning switch which receives the operation or non-operation of the compressor, a temperature setting portion which sets a set temperature inside the cab, a room temperature sensor which detects a room temperature inside the cab, and a controller. In a case where the air conditioning switch is operated and the room temperature is higher than a set temperature, the controller maintains the rotation amount of the cooling fan at a limited rotation amount or more.
