A wheel loader, which is a construction machine, includes: a rear vehicle body and a front frame; an operating device provided at the front frame; and a working lamp unit attached to a sidewall of the rear vehicle body. The working lamp unit has a light source and a bracket including a downward illuminating portion that covers at least an upper part of the light source and that protrudes more in the light illumination direction than a lens surface of the light source and that is inclined downward with respect to a horizontal direction. Thus, there is obtained a construction machine including a working lamp, in which visibility can be ensured both in a distant area and in an area near the construction machine.

Construction machine

A cooling system that is capable of cooling a working vehicle, such as a wheeled loader, at a good efficiency and at a reduced level of noise. Plural radiators are arranged in a V-shaped form within a plane behind an engine mounted in the rear of the engine compartment of the vehicle. The radiators are spread a part rearwardly to form a space between them. A cooling fan is mounted in this space. The side surfaces of the radiators are provided with intake ports that are covered by openable side covers. The top of each intake ports is covered by a hood whose top surface can be tilted rearwardly and downwardly.
