The invention provides a portal forward-moving type forklift. The portal forward-moving type forklift is characterized in that racks are arranged on the opposite inner side faces of a left support and a right support correspondingly; a push-pull block and a gear are arranged on the left and right sides of the portal respectively; the left supporting leg and the right supporting leg can move up and down between a first vertical position and a second vertical position relative to the left support and the right support respectively. The push-pull rod moves back and forth between a first translation position and a second translation position relative to the left bracket and the right bracket respectively; the front end of the push-pull rod at the first translation position is not in contact with the left supporting leg and the right supporting leg; when the push-pull block pushes the push-pull rod to move forwards together to a second translation position, the front end of the push-pull rod applies downward pressure to the left supporting leg and the right supporting leg, so that the left supporting leg and the right supporting leg move downwards to a second vertical position, and the push-pull rod moving to the second translation position is disconnected from the push-pull block; therefore, the push-pull block can continuously move forwards. According to the forklift provided by the invention, the gravity center of the forklift can move backwards, and the forklift is easy to maintain.

    本发明提供一种门架前移式叉车,包括:左支架和右支架在相对的内侧面分别设置齿条;门架在左右两侧分别设置推拉块和齿轮;左支腿和右支腿分别相对于左支架和右支架在第一竖向位置和第二竖向位置之间可上下移动;推拉杆分别相对于左支架和右支架在第一平移位置和第二平移位置之间前后移动;位于第一平移位置的推拉杆靠前的一端不接触左支腿和右支腿;推拉块推动推拉杆一起向前移动至第二平移位置时,推拉杆靠前的一端向左支腿和右支腿施加下压力,以使左支腿和右支腿向下移动至第二竖向位置,并且移动至第二平移位置的推拉杆与推拉块之间断开连接,以实现推拉块向前继续移动。根据本发明提供的叉车,可以实现叉车重心后移,易于维护。
