CONSTRUCTION MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/031427
Kind Code:
A1
Abstract:
A construction machine that is a wheel loader (1) is provided with a rear vehicle body (2) and a forward frame (5); a work apparatus (30) provided on the forward frame (5); and working light units (7a, 7b) attached to the lateral walls of the rear vehicle body (2). The working light units (7a, 7b) have a light source, and a bracket that covers at least the top section of the light source, projects farther outward in the illuminating direction of the light than the lens surface of the light source does, and includes a downward illuminating part that slants downward in relation to the horizontal direction. As a result, it is possible to obtain a construction machine provided with working lights capable of ensuring visibility both far from and near to the construction machine.
