Description

Technical Field

[0001] The utility model relates to a lifting and positioning forklift frame, belonging to the field of forklift accessories. Background Art

[0002] Two sets of lifting guide rails need to be installed at the front of the forklift so that the forklift arm can move along the lifting guide rails to limit the direction of movement of the forklift arm. The two sets of lifting guide rails are installed on the connecting seat at the front of the forklift by bolts. In order to ensure the stable connection between the lifting guide rails and the connecting seat, multiple bolts are installed between the connecting parts of the lifting guide rails and the connecting seat. The spacing between the multiple bolts is small, so that the force applied to the lifting guide rail when the forklift arm lifts heavy objects acts on a small area of ​​the connecting seat. The part of the connecting seat where the lifting guide rails are installed is subjected to a large load, which affects the stability of the structure. Therefore, it is necessary to design a lifting and positioning forklift frame that can disperse the force applied by the forklift arm on the lifting guide rails to different areas of the connecting seat.
