Engineering vehicle

Abstract

The invention discloses an engineering vehicle which comprises a rear vehicle frame. The left side and the right side of the rear vehicle frame are each provided with at least one rearview lamp in a pivoted mode. The rearview lamps can be rotated between an unfolding station and a folding station relative to the rear vehicle frame. When the rearview lamps are rotated to the unfolding station, light emitted by the rearview lamp hits the rear area of the rear vehicle frame. When the rearview lamps are rotated to the folding station, the projection of each rearview lamp in the horizontal plane is located in the projection of the rear vehicle frame in the horizontal plane. When the engineering vehicle is driven at night to turn or back, the rearview lamps are rotated to the unfolding station to illuminate the outer sides of rear axle tires and the tail area of the engineering vehicle; during normal driving, the rearview lamps are rotated to the folding station, so that the rearview lamps are located in the area of the rear vehicle frame, and the problem that the engineering vehicle is ultra wide due to the existence of the rearview lamps is avoided.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an engineering vehicle. Background technique [0002] In the prior art, construction vehicles such as concrete pump trucks, fire-fighting aerial ladder trucks, and cranes generally have longer bodies. When reversing or turning at night, the driver cannot observe the road conditions at the rear of the engineering vehicle through the rearview mirror, which makes There are potential safety hazards for drivers in the process of turning or reversing engineering vehicles at night. At present, the electric lighting system installed on the body of the engineering vehicle is generally only a width indicator light. Its function is to facilitate the pump driver and other personnel to know the body length and width of the concrete pump truck at night, and cannot reverse or drive at night. Provides night vision when cornering. Contents of the invention [0003] The invention...
