Description

Technical Field

[0001] The present invention relates to the field of loaders, and particularly to a side-shifting and distance-adjusting fork device for a loader. Background Art

[0002] The fork device is a commonly used working attachment for loaders and is widely used in complex working scenarios such as warehousing management, construction, agricultural production, and port loading and unloading. These working conditions usually have limited working space and materials need to be closely arranged.

[0003] The forks of existing loaders are usually fixed and the forks themselves cannot move laterally. When the materials are offset, the body position needs to be frequently adjusted, and when facing material pallets of different specifications, the fork spacing needs to be manually adjusted, which greatly reduces the working efficiency of the loader and limits its use in narrow spaces or variable working conditions.

[0004] Therefore, it is necessary to specifically develop a side-shifting and distance-adjusting fork device to overcome the above problems. Summary of the Invention

[0010] Among them, a side-shifting oil cylinder is provided above the cross plate; one end of the side-shifting oil cylinder is connected to the mounting seat above the cross plate, and the other end of the side-shifting oil cylinder is connected to the ear seat of the bracket. When the side-shifting oil cylinder expands and contracts, it drives the forklift carriage to move laterally relative to the bracket.

[0011] Among them, the fork teeth are installed on the forklift carriage through distance-adjusting pins; a distance-adjusting oil cylinder is provided below the cross plate.

[0012] Among them, both ends of the distance-adjusting oil cylinder are respectively connected to the fork teeth on the left and right sides of the forklift carriage.
