Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

A welding steering bridge structure for a forklift comprises a bridge body main body, wherein an upper bridge plate 2 and a lower bridge plate 3 which are horizontally arranged up and down relative to the bridge body main body are connected by an upright web plate in the middle of the upper bridge plate 2 and the lower bridge plate 3; the middle of the front side and the rear side of the bridge body main body is symmetrically provided with a pair of upright end plates 5, the upper ends of the end plates 5 are fixedly connected with the upper bridge plate 2, and the lower ends of the end plates are fixedly connected with the lower bridge plate 3; a pair of main pin seats 7 are correspondingly arranged at two ends of the main bridge body.
