按照门架的级数进行分类,单级门架只有一个门架,叉车沿着它起升,最大起升高度永远低于叉车高度,结构简单,刚性好,只有起升高度很小的叉车上采用。两级门架,在单级门架的基础上多加了一个内门架。
In accordance with the classification of series door frame, single door frame only one door frame, along which forklift lifting, maximum lifting height is always lower than the height of the forklift, simple structure, good rigidity, only by lifting height small forklift. Two door frame, door frame based on single stage more of a portal frame.

Partial lifting, refers to the goods fork lift from the ground up to the maximum height of the process, generally can be divided into three stages. The first stage is the fork to the hydraulic cylinder 2 times stroke lifting, the inner frame does not move, the forklift vehicle height does not change.

The third stage door frame and fork synchronization with 2 times of hydraulic cylinder lifting until the maximum lifting height.
