Abstract

The invention discloses a portal frame assembly used for a forklift and the forklift with the same. The portal frame assembly used for the forklift comprises a first portal frame, a second portal frame arranged on the outer side of the first portal frame, a free lifting oil cylinder arranged on the inner side of the first portal frame, a free lifting chain wheel arranged on the top of the free lifting oil cylinder, a free lifting chain wound around the free lifting chain wheel, an installation piece and an oil pipe, wherein the free lifting chain wheel is driven by the free lifting oil cylinder to vertically move relative to the first portal frame; the installation piece is arranged on the side, away from the free lifting chain wheel, of the free lifting chain; the oil pipe is wound around the installation piece. By means of the portal frame assembly used for the forklift, the oil pipe is wound around the free lifting chain, so that a large number of oil pipe clamps and oil pipe idler wheels are omitted; the structure of the portal frames is simple, compact and orderly; the view of a driver is widened. In addition, the installation piece is simple in structure and convenient to assemble and produce.

Description

Technical field [0001] The invention relates to the field of forklift equipment, in particular to a mast assembly for a forklift and a forklift having the same. Background technique [0002] It is pointed out in the related art that the stability of the free-lifting cylinder of the three-level full-free mast is poor during lifting, which causes the lateral rollers on the fork frame and the free-lifting cylinder itself to be easily damaged and abnormal lifting noise, which reduces the door The service life of the frame, and during the lifting process of the free-lifting cylinder, there will be problems in the middle part of the mast that the oil pipe blocks the view, and the appearance of the entire mast is messy. Summary of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, an object of the present invention is to provide a door frame assembly for a forklift, which has a simple, compact, orderl...
