The invention relates to the field of forklift structures, in particular to a wide-view three-stage portal. Comprising an outer door frame with a fixed position, a middle door frame connected to the outer door frame in a sliding mode, an inner door frame connected to the middle door frame in a sliding mode, a second-stage oil cylinder arranged on the outer door frame and driving the middle door frame and the inner door frame to move synchronously, a fork arm carrier connected to the inner door frame in a sliding mode, and a first-stage oil cylinder arranged on the inner door frame and driving the fork arm carrier to move. The two first-stage oil cylinders are located on the two opposite sides, close to the middle portal frame, of the inner portal frame in a one-to-one correspondence mode, and the positions, away from the fork arm carrier, of the two first-stage oil cylinders are each provided with a pipe clamp for fixing the position of an accessory oil pipe. And a fixer for allowing accessory oil pipes at the two primary oil cylinders to jointly penetrate through for position fixation is arranged at the position, close to the primary oil cylinders, of the inner portal frame, so that view blocking caused by the primary oil cylinders and the accessory oil pipes is reduced, and the possibility of danger occurrence is reduced.

    本申请涉及叉车结构的领域,尤其是涉及一种宽视野三级门架,包括位置固定的外门架、滑动连接于外门架的中门架、滑动连接于中门架的内门架、设于外门架且带动中门架和内门架同步移动的二级油缸、滑动连接于内门架的货叉架、设于内门架且带动货叉架移动的一级油缸,一级油缸设置两个且一一对应位于内门架靠近中门架的相对两侧处,两个一级油缸背离货叉架的位置处均设有对属具油管进行位置固定的管夹,内门架靠近一级油缸的位置处设有供两个一级油缸处的属具油管共同穿过以进行位置固定的固定器,以减少一级油缸和属具油管造成的视野阻挡,降低危险发生的可能性。
